Just called Asus for a problem with my router, went to send them my systemlog.txt for analysis
"Oh we don't have an email you can send that to"
Me: "(me calling bullshit) let me talk to the tech team.."
"Hello this is the supervisor"
"Ya we don't have an email you can send that to, but we can use a different departments verification services to get a file from you, has to be a picture though"
Me: "What? I got a .txt file here, I just want to get it to you, does it really have to be a picture?"
"Has to be a picture or a PDF, we can't take txt files"
Me: "fkin.. srsly? Fine"
I can't believe Asus's system srsly. I think it's for virus protection, but viruses can be embedded in both picture formats and PDF, but not in txt. So wtf is going on lol15
Networking Professor: Alright, how many of you disagree with the way Google collects and uses data?
*basically everyone in the lecture hall raises their hands*
Professor: Okay, now if you were offered a job at Google, how many of you would still take it?
*everyone raises their hands.*23
Six months ago my girlfriend broke up with me...
BUT since then I've...
•Found the wonderful world of devRant
•Gotten back into electronics
•Taught myself PCB design
•Gotten back into programming
•Made a discord bot
•Started teaching myself calculus
•Began building an ai for said discord bot
•Designed a wireless mesh networking NIC for the TI84+CE
Sure I feel like shit most of the time but before I did anyway but I've been super productive and it feels kind of nice48
Came home to visit parents
Dad - Internet on my laptop isn't working (I switched him on a Ubuntu platform because he picked up a hobby of mining for viruses while doing..... "research" )
Me - did you mess with your networking settings again
Dad - (Defensible sounding) Noou
Me - (looking at settings, networking is switched off)
Me circa 3am - writing a python script to check for this automatically cos fml this is basic
Thanks for listening13
Me: Hey Dave, wanna hear a TCP joke?
Dave: Uhh, sure...
Me: OK I'll tell you a TCP joke..
Dave: Please don't.
Me: Are you ready to receive my TCP joke?
Me: OK I'm sending my TCP joke. It'll be 4 words long and 27 bits large.
Dave:... Screw this, I'm going home now.6
Holy fucking hell!
Who the fuck sets up a local network with an 255.255.0.0 subnet mask and then lets the dhcp-server distribute clients onto the 192.249.x.x., 192.2.x.x and the 192.22.x.x networks AT FUCKING RANDOM???
I need to SSH onto 40 routers distributed across the entire campus and have a WORKING internet connection while doing so and you make me spin the connect-disconnect-wheel. Fucking hell dude, don't give me that "Uh, it wasn't intended for this size"-bullshit. You have about 200 active devices. And in one subnet you have space for more than 60 000. Fuck you, dumbass! OH, YOUR FUCKING LIST IS FUCKING WRONG AND YOU DON'T REMEMBER THE IP OF THE ROUTERS? OH FUCK YOU EVEN HARDER!!!
Goddamn people why does legacy maintenance always suck so much?😭😭😭4
"could you please just use the standard messaging/social networking thingies? That way it'll be way easier to communicate!!"
Oh I don't mind using standard tools/services which everyone uses at all.
Just a few requirement: they don't save information that doesn't need to be saved, leave the users in control of their data (through end to end encryption for example) and aren't integrated in mass surveillance networks.
Aaaaaand all the standard options which everyone uses are gone 😩33
Being a sysadmin, it's pretty difficult to get around the whole development of front-end stuff.. positioning, scaling, and everything... I hate it. So many ideas but only the ability to make the back-end and if it involves electronics that as well as networking. But building a pretty UI is beyond me... I love hating on all the frameworks and Node, but in all honesty.. front-end people, I kind of envy you 😅6
That moment when the resident IT guy/teacher at your school comes to you at lunch and you look sad.
Teacher: What happened?
Me: Batteries almsot dead :(
Teacher: Well, I've got good news for you. I was talking to the school director about you.
Me: Um ... shit
Teacher: We're looking to get you an intership at the company that does networking shit for us (Netcom, anybody?)
Me: FUCK YEAH ... thanks!
*Day brightened by angelic light*8
As a full time remote employee it gets lonely. Im getting ready to turn my home into a co-working space :
* Plenty of space with tables and couches
* Gigabit Internet backed by enterprise networking gear
* Lots of fresh ground coffee
* Local Kubernetes server !
* dog friendly chill space
* kid friendly play areas during the summer
* Mountain home with backyard hiking trails , wildlife lookout (wild deer live in my back yard), and fireplaces
What else would you want in your co-work space-at-my-place (TM)?14
Top 5 reasons to come to Hackathon
1. Experience for your CV
2. Free swags
4. Free swags
5. Free Stickers (swags)11
Had a team with
1 entrepreneur who has this great billion dollar Idea and want me to sign an NDA before he can share the idea
1 newb who thinks that X language is the coolest because that's what everyone on Hacker news says
1 person who spends more time with other team than yours. I'll be fortunate to even spot him during the hackathon. Aka, "networking guy"
And then there's me, wondering why was I even here in the first place
Oh wait, that's the every hackathon I've been to.8
I JUST GOT THE JOB OFFER!!! They are paying me well and with full benefits and they are going to pay for extended training on top of that!!
This internship was one of my better decisions! :)7
The download speed surpassed the speed of light this going backwards in time and appearing as negative number.
Doing some cable management, realizing after having disconnected all the cables that I've been working on the wrong rack. This is the rm -rf * of networking 😭6
A completely normal workday.
Until suddenly... the Internet was gone. Like completely gone.
Out of nowhere the head of network administration appears right beside me, yelling completely over-pitched straight into my ear "WHAT DO YOU MEAN BY ALL SERVICES ARE OFFLINE? WTF HAPPENED TO THE CONNECTION?..."
He disappeared as fast as he had arrived. With my ears still bleeding I got myself a cappuccino.
Several hours later the Internet was back. At the construction site infront of the headquarter the Internet cable was cut.
Wait. What about a second backup cable? It exists. Unfortunately both cables split only after the construction site.
You had one job anonymous engineer...2
I'm penetrationtesting a network and the servers on said network
The network administrator and IT security officer knows this, because they hired me..
TL;DR a scan caused the network to crash.
Today I received a very angry email going "Stop scanning NOW!" from one of the IT departments.
Apparently I crashed their login server and thus their entire network...
It happened d the first time I scanned the network from the outside and they had spend an entire day figuring out how and repairing the service they thought was the problem, but then it crashed again, when I scanned from within the network.
Now they want to send me a list of IP's that I'm not allowed to scan and want to know exactly what and when I'm scanning...
How crap can they be at their job, if they weren't able to spot a scan... The only reason they found out it was me was because the NA had whitelistet my IP, so that I could scan in peace...5
When your boss says "good job, you have developed something big in such a small time" (~2 weeks) but you haven't showed him the bugs and shit (gonna fix it btw)3
Many have python learning as their 2018 goal, well theres a 15$ huge humble bundle for python machine learning, networking, rest, pen-testing and more, its a good deal, check it out.59
Removed my Facebook account about Month ago. Sister was pretty sad because I'm the one person she can tag in everything. Asked me why I deleted it and I told her it was because of privacy concerns. "Then why don't you make an end to end encrypted social network?". I'd actually consider this...11
The school I went to...

Congratz for the graduation in the Pre-school of Developers (11-14 yrs old) :)5
I'm going to make 4 statements of which only 3 are true. You tell me in the comments which 3 are true.
1. At my job in the marketing department, I manage our Facebook ads campaign where we spend hundreds of thousands of dollars in advertising.
2. MIS department inexplicably blocked the marketing dept from the Facebook domain altogether near the end of the day.
3. They also block Dropbox although we still have to manage all the distribution of digital video and commercials to our tv advertisers.
4. I work in a technically progressive environment that understands how things work online.2
My manager shared the wwwroot folder directly to mine and his machine so we could move files to the server easier.
This messed up the IIS_IUSRS permissions. Turns out he did it to the production server and not the development server. So now everybody that relies on the site to do their job is fucked. Neither of us knowing especially much about IIS or networking can't fix it.
Don't worry though, the fucking cunt flap is telling everybody that I did it as he's been there for 30 odd years and doesn't want to tarnish his rep.
They're requesting that the server be rebooted in hopes it'll fix the problem.
Can't wait to go to work tomorrow.......12
If you're wondering which new language or framework to learn in 2017, I suggest you learn instead about the lower levels of networking, computer hardware and how to see things from a user's perspective.
These things will help you make smarter software.8
I've just come back from a business networking event. There was a speaker who gave a talk about not wasting time.
On of her points was catching up on emails, from your smart whilst waiting to go into meetings, as that's apparently wasted time.
All I do whilst waiting to go into meetings is read devrant :)
It puts me in s good mood :)3
I'm sitting here writing a page permission control system in PHP at my internship when a fellow intern (he does something with networking) comes to me showing his first line of PHP being all proud :). I'm really proud of him because that's how we all started, didn't we!3
My friend: This networking internship is so boring! When will they start teaching the cyber security portion of it?!
Also my friend: *downloads a chess app on his phone to pass the time and allows it permission to access his media and contacts*5
Networking class. We're learning to configure switches, or at least trying to. A full hour goes by and the thing is not making a single beep. I frustration we lean back. Then my friends sees it. We never plugged in the power cable.6
At college (UK) and taking a general IT course (databases, programming, networking) a friend suggested "We should make our own network protocol." (The only language we had covered at the time was Visual Basic)4
Dev(null networking knowledge): -"i've already deployed the web but it isn't up."
Boss(strong networking skills): Found port 80 blocked.
-Option A: open port 80.
-Option B: disable firewall.
Choose option B.
TLDR: There’s truth in the motto “fake it till you make it”
Once upon a time in January 2018 I began work as a part time sysadmin intern for a small financial firm in the rural US. This company is family owned, and the family doesn’t understand or invest in the technology their business is built on. I’m hired on because of my minor background in Cisco networking and Mac repair/administration.
I was the only staff member with vendor certifications and any background in networking / systems administration / computer hardware. There is an overtaxed web developer doing sysadmin/desktop support work and hating it.
I quickly take that part of his job and become the “if it has electricity it’s his job to fix it” guy. I troubleshoot Exchange server and Active Directory problems, configure cloudhosted web servers and DNS records, change lightbulbs and reboot printers in the office.
After realizing that I’m not an intern but actually just a cheap sysadmin I began looking for work that pays appropriately and is full time. I also change my email signature to say “Company Name: Network Administrator”
A few weeks later the “HR” department (we have 30 employees, it’s more like “The accountant who checks hiring paperwork”) sends out an email saying that certain ‘key’ departments have no coverage at inappropriate times. I don’t connect the dots.
Two days later I receive a testy email from one of the owners telling me that she is unhappy with my lack of time spent in the office. That as the Network Administrator I have responsibilities, and I need to be available for her and others 8-5 when problems need troubleshooting. Her son is my “boss” who is rarely in the office and has almost no technical acumen. He neglected to inform her that I’m a part time employee.
I arrange a meeting in which I propose that I be hired on full time as the Network Administrator to alleviate their problems. They agree but wildly underpay me. I continue searching for work but now my resume says Network Administrator.
Two weeks ago I accepted a job offer for double my current salary at a local software development firm as a junior automation engineer. They said they hired me on with so little experience specifically because of my networking background, which their ops dept is weak in. I highlighted my 6 months experience as Network Administrator during my interviews.
My take away: Perception matters more than reality. If you start acting like something, people will treat you like that.3
i just started learning about networking by sending a packet saying "emoji movie leaked footage" from my laptop to my desktop
for some reason, the fact that i can have two computers interact fills me with some kind of inexplicable joy5
>Be my networking teacher
>Give a really hard test with way more topics than we're realistically able to study
>16 out of 22 fail the test
>Announce 14 hours before that we're gonna repeat the test (we had the test on monday...he sent an email on sunday)
>Give a slightly harder test
>19 out of 22 fail the test
>Get annoyed because, in your opinion, the students don't study enough4
Question for networking persons or persons who might know more about this than me in general.
I'm looking at setting up a server as vpn server (that part I know) which tunnels everything through multiple other vpn connections.
So let's say I've got a vps which I connect to through vpn. I then want that vps to have one or multiple connections to other vpn servers.
That way i can connect my devices to this server which routes everything to/through other services like mullvad :).
Tried it before but ended up losing ssh access until reboot 😬
Wk1:, Client wants stack deployed to AWS in a day... Does it in 30 minutes...
Wk2: client complains about cost of service so requests I downsize the stack they asked for... Does so... Just to save some £££ at loss of any DR or HA capability
Wk3: Client wants stack moved to a different AWS account just cos... Advised could cause issues... Client says carry on. Migrates to account as requested on the days they requested.
Wk4: client complains that said migration caused issues and that proper change control wasn't followed..... That was never informed on..
Wk5: issue discovered to actually be network fault linked to clients wanting every £££ saved in AWS... And as the stack specialist I still have to write up a summary and findings?
Wow just get a decent AWS admin will ya....3
Let's hear your embarrassing confessions.
I'll start: I have never built my own PC's or set up my home network.
I don't really know much about hardware and physical networking, and frankly I can't be bothered to deal with it.32
Dad: God I hate Windows!
Me: Why? You know you can just run the getmac command in CMD, right?
Dad: What? There is a command for that?
Needless to say, my dad is not a network engineer...1
Today the IT deparment update the firewall's configuration, they blocked almost every website except email and Google.
- Blocked some systems outside the organization, there are in another building and also network
- I can search on Google but I can't see the results outside Google
- Forget about download depencies, libraries, deploy code to outside services, search at StackOverflow
I JUST WANNA SAY GOOD JOB, GUYS
PS: The firewall also block the SSH port, I had explained to my boss and he sent a request for allowing the port, so far no answer3
I have to connect to a VPN, then RDP onto a machine halfway across the world and then use TeamViewer to access the client's test environment 🙄.
And during a Skype call, one our boss says 'There's too much lag from your end'😤10
So I'm 17, I go to a vocational school and I'm in a computer IT and networking class as a junior. We have learned programming in HTML and CSS and whenever I'm programming I'm having the most fun, so I am teaching myself C++! I don't really feel welcome due to my age but I hope all of you can help me in the future!17
When someone says they are a 'HACKER' whereas all they do is watch videos of 'How to hack a GMail account' on YouTube and read 'Learn to hack in 24 hours' , while having no knowledge of networking, security protocols and ports.10
Am I the only one who hates meet-ups and networking events? We were supposed to be introverted geeks!8
FB: once in a month
Twitter: only on notification
Gmail : twice in a day
devRant: whenever I unlock the mobile6
I passed my Security+ cert exam! I know a lot of people say it's super easy, but it actually has a lot of really specific networking stuff, and some legacy tech specifics, etc.6
!rant && networking.
Just moved offices and the previous guys (architects) left this baby here.
Not 100% sure what it is or what I can do with it but I know someone here will.
Please help oh mighty networking, sys and ops gods!7
Where I work we develop drivers and command-line software for embedded systems. The contracts we have with our customers tend to be in the £100k-£500k range and are usually completed in 6 - 9 months; our team is made up of 20 developers. You would think that it would be worthwhile investing in the department. But no, instead we have to deal with >10 year old build servers on their last legs; limited numbers of development boards with wires soldered on so that we can keep up with new board revisions; no room for R&D into new products; and to top it all off, not one of the executives has a laptop on par with the placement students in the next department. It's like the company is trying to kill the department, we've seen our staffing dwindle with no new graduate (or higher) positions being made available in the last 3 years while we've lost at least 5 people to other places. I just don't get it!3
Classroom fuckery: I'm in a Computer Information Technology program and I usually spend the last hour of class working on code. Most of the people in this program are going into networking or security. This kid looks over and freaks out, starts yelling that I'm breaking into the school's network. I was on freecodecamp.com.5
Our university labs still use computers with 512mb ram, celeron processor for programming and networking courses. Even worse some of the mouse/keyboards/monitors not working and we occasionally have to do exam on those machines ...7
There was a girl that I fell in love with.
As I went on a journey
We were separated by oceans
In order for me to reach her
I studied networking and programming
She is the reason
why I code1
Memo on August 4th: Staff, we're moving to the new building. IT, make sure the building is ready by September 15th.
IT: But the entire networking, surveillance, fire suppression (yes, we do that too) and power management systems have to be installed/redone.
Management: What's so hard about that? Just get it done.
Memo about a week ago: Timeline for move shifted to September 9th
IT: Sir, this request is unreasonable especially since you still want us to go through the usual procurement process of hiring vendors to deal with stuff.
Management: So you mean to tell me you can't handle that in the next couple weeks?
IT: We're a large organisation with ~300 employees. The data centre in the new building isn't even usable yet.
Management: I don't care. Make sure everything is placed and operational by the 5th. Stop making a mountain out of a mole hill!4
3 hours of "I don't have access to that router" and waiting for someone who does have access to join the line. And then they don't have access, etc..
I love networking, hate working with network engineers.
Bought a domain name to sell in the category of social networking.... then realized it sounds erotic10
Since I already posted images of my desktop setups at work(Mac) and home(Linux), I didn't want to repost this week. So, to keep it at least mildly interesting, here's a shot of my garage networking setup.
Ubiquiti UAP-AC Lite
TP-Link cable modem
A big UPS, so we'll still have wifi during a power outage, since that's apparently important
A couple of older machines I'm working on when I have time
A Philips Hue Bridge
An unremarkable 7-port switch
An Ooma phone device
A shitload of my wife's stuff that she's left there on her way in and out of the house.6
My friend cracked that UDP joke in an interview!
wham! He's now a networking engineer at Cisco! :D
Moral: Learn all the classic jokes before giving an interview!4
Friend: Networking is important. My boyfriend introduced me to X, who then introduced me to Y and that's how I got a job.
Later that day...
Friend: Why didn't you apply for this party? What did I say about networking?
Me: Because I didn't know and because I don't follow that guy on twitter so I didn't see he tweet the google forms.
In my mind: How come nobody introduces me to anybody?
I was just mad that this happened and had to get this out of my head. Nobody ever introduces me to anybody and I am really really shy and an introvert, so I almost never introduce myself to anybody. Clearly I'm gonna die homeless or have a shitty job. Hey artists, I'll gladly take that fucking exposure!10
Spent an hour trying to figure out what was wrong in my socket disconnect detection code because it was constantly reporting disconnects when it shouldn't have... Only to find it was a pinched cable causing the problem. Meaning it actually did work the entire time.1
Well I met my wife and decided my current profession wasn't going to give us the life I wanted for us. So since I did IT communications in the Army, I decided to look into that field, buy I knew I didn't want to do networking; I hated it in the Army. I read about programming I saw that I could learn some for free online before I chose that as a career. I did the website courses on Codacademy and thought it was a lot of fun! So I enrolled in It's software program, got 1 quarter away from an AAS in software development, then while I was on my honeymoon, they shut all the schools down and filed bankruptcy. Now I've started all over and community college to eventually get a BA in computer science.7
Fuck the brains of circular dependency.
On a fresh install of OS X on my hackintosh.
1) Let me install HomeBrew
2) I need Command Line Tools to install HomeBrew
3) Xcode dmg is on my Android. Opens Android File Transfer tool.
4) Error: File is larger than 4GB. Need to use adb.
5) Need to install android-platform-tools, which contains adb.
6) android-platform-tools is available in brew. Goto 1).
Note: Networking is limited to tethering mobile data as Wifi chip hasn't arrived yet.4
the admin that was pleasantly surprised a developer was interested in admin work. he taught me alot about linux, networking and vsphere because of him i get to do quite alot of admin type work in my new job, i love it!1
As we're all going about our various Easter, Passover, et al., family celebrations, I have the perfect solution to help train your families to stop asking you for help with mundane computer stuff:
Every time someone asks you to do/fix something, give them a full talk about what is going on in their computer around that system.
Don't forget you can talk about lots of things too:
- TCP IP / socket networking
- multi-threaded programs vs. single threads
- RISC vs. CISC processors
- Why linux is better than Windows or Mac
- logarithmic runtime
- teach them how to convert between hex, binary, and base ten
Really pour it on too. Soon they'll either figure out that you are a highly-skilled individual who is not their personal geek squad, or they'll be too afraid of a big lecture to ask for help.
Works with my in-laws like a charm.6
My uncle who thought me Computers and Networking ( I once worked with him on a project ) came by to my house today. He said that he created a software that automates his work on the boring stuff so when he has free time he works on his own company. My man!2
I love Unix, Linux all that shit (macOS can fuck off though). But why WHY WHY does every pissing update have to break something?! Guys I need fucking networking, not even intertubes just basic networking.
Anyway, I've come up with a solution. It is quicker for me to install a new OS and restore files from backup than to fix it, so that's what I do.16

trying out this hot new VPS host named Skysilk, aside from the EAI_AGAIN networking issues and a too basic dashboard, it works fine. Other than that its a good host. Would recommend3
Because of networking, arch is harder to install on vbox.
guess who wiped and GREW his old antergos partition?
wish me luck in the arch install6
Well today we got to test our system to the extreme and I'm pleased to say it passed. Major power surge followed by a black out. UPS for all networking and servers kicked in without missing a beat and the standby generator outside about 45 seconds later. After explaining to users how to turn on their computer (😑), we were able to get everyone working again in about 5 minutes. Lasted three hours without power from the grid without any client downtime1
that moment when you have to learn Docker at work, so you convince networks teacher to do that in classes.3
I use a Mac that implements MAC using MAC and its got multiple hardware MACs along with a hardware MAC.... btw, I'm eating a Big Mac.
Media Access Control - Networking
Manditory Access Control - Security
Message Auth Code - Security
Mac - Apple
Multiply ACcumulate - Chip Design2
I just misread Cinco de Mayo as Cisco de Mayo and started imagining what kind of party Cisco de Mayo would be....7
Someone in my class disabled my networking card from BIOS. Took an hour to find out why it was not working.
This is a followup to my earlier RealTek networking rant.
After reviewing and researching all of the wlan adapter suggestions on that rant, as well as a few more, I settled on an Alfa AWUS036ACH usb3 wireless-ac adapter. Every Alfa I've ever owned has been amazing, so I happily bought it.
It arrived today, and I excitedly threw my existing RealTek garbage across the room, hooked up my fancy new toy, and... nothing.
Fearing it was doa, I ran `lsusb` to see if it was even showing up... and it was! but identifying itself as a RealTek device...?
All of my research showed it uses the Atheros9k chipset. It's advertised and praised as using the "famous Atheros AR9271 chipset" and the Ath9k drivers. Except this particular unit appears to use the RTL8821AU chipset, therefore requiring RealTek drivers. askfja;sldf.
I unhappily fetched the garbage from the dirty laundry where it landed, installed it, and began my research anew.
I found, among all of the wonderful promises of Ath9k bliss, a thread on the Kali forums corroborating the RealTek driver nonsense, and it explained how to get the RTL8821 drivers working with it. which is pretty much the very last thing I want to do.
If you've read any of my networking rants, well, they've all been about how totally awful RealTek linux drivers are, and that's pretty much common knowledge anyway. So I'm like extremely pissed off.
ARGH WHY IS NETWORKING WITH LINUX ALWAYS SO FREAKING DIFFICULT? haslkfjasgdskg6
Wtf. So if I say I'm a web developer and I say I'm from Russia. Then I am automatically a hacker for you? "Web developer + Russian = 95% chance of being a hacker". Yeah, right. Since now, right after I say I'm from Russia I always add this: "No, I'm not a hacker and no, I didn't hack the last election, but I can tell you your last four digits of your SSN if you show me your debit card". Guess what, no one wants to talk to me anymore.12
I restarted my studies today like it's 1999.
Got a laptop, a VPS based on OpenStack,
a university in my browser, an empty Github account(cue the sad horn), Python, Apache, five cups of coffee(and tea) and a neurosis for perfection.
First goal is going to be getting my LFCS certification
which i started two days ago.
Next up will be Networking and CEH side of things.
Continuing on with developing(Python,Django,HTML5).
I think with the above i'm covered for the rest of my piddly-ass life.
*puts on fedora* Somebody stop me!7
The networking closet I had the pleasure of working in most of last night. That's all very loud, very warm air compressors at the bottom, and the switch, firewall, and modem up near the top. And all they had was a small step stool...
About to start my real first Java project to learn the language in-depth: a virtual ATM featuring a GUI and a networking system for the transmission of banking data to and from a server. Since I particularly care about security this will surely help me get a better understanding of everything involved. Wish me luck.16
This is true incident from my college...
We had computer networks oral exam.
Sir asked student what is Socket.
Student answered "That one on the wall"1
I just got an email that a client changed their DNS zone files to point at a new server. Turns out that they haven't set the server up yet. Client is wondering why that domain's emails aren't working, and why their site is down. They didn't want to give me the Domain's portal login credentials until now, because they "could do it without [me]." Tomorrow morning should be fun.4
I've really struggled to make friends with people who code... and it's been absolutely frustrating. Does everyone in this industry have a god complex or something? Everyone I try to make friends with ends up being super narcissistic and self obsessed it's crazy. One of them wanted to be my mentor a while back, and we still talk occasionally, but after getting to know him I decided I didn't want to learn from him. It turns out he only mentors people to showboat his greatness and claim later that all their success is directly his doing. I decided I wasn't going to be one of those people and I only ever had 2 sessions from him. One of the best choices I've ever made. But I've found a lot of people who are programmers tend to be a lot like him. A lot of them I talk to will hit me up to brag about themselves or what they've done. But none ever ask what's been up with me or how my journey is doing? Is this just a normal thing in this industry or am I just meeting terrible people. It's made me appreciate my slightly dumber friends, cause at least they care about me and it shows.
More a rant than anything, but genuinely curious if anyone else has this issue... I'm starting my bootcamp soon and I'm hoping to make friends but I'm so concerned about this it's kind of giving me anxiety.14
Anybody up for a Skype hangout tomorrow (Sunday, 03rd of June)?
My time zone: +05:30 GMT.
- General introduction
- Sharing dev and life experiences
- Anything else you wish to have28
The very first sentence in my profile on many freelancing and networking sites is "I am not looking for a full time job at the moment!" I still get fat to many job offers from recruiters, who apparently cannot read.1
At my last gig I was working at a small ISP and my boss was asking why our throughput went to shit every time he checked the router web ui. I told him it was because the web server on the router uses up a lot of CPU time, and that meant the router couldn't process as many packets since it uses that same CPU for well routing, nat, firewall rules etc...so it's probably best to use the CLI instead. Boss says, "YOU DON'T TELL ME WHAT TO DO!!!" And continues to destroy throughput by looking at the web ui.
TL;DR Boss yelled at me for telling him how things work. Yay.2
I don't know how others feel about this but every time, when the fan are spinning at full speed as you turn on the routers and they are in boot sequence.the stat lights on switch turning on/off in wave patterns
prepare to take off,

4 and a half years doing socket/network programming and I only just learnt my understanding of TCP was largely incorrect...
Well then... That's something...4
Since there is Scrum i am programmer , tester , software engineer , networking guy and application manager. Thank you Scrum didnt know that before. And i have no idea what i am doing right now ....3
So my girlfriend was Gavin wifi problems and she calls me to fix it with vague description of what's happening (not even enough to google).
"But I'm a programmer?"
"That's networking, they're quite different"
"It's computer stuff it can't be that different"8
CS Teacher today:
"Transport Layer provides Security and Encryption to the communication" (TCP/IP stack)
me: WTF? Encryption is provided on the *top* of the transport layer (aka Application) ( and below [Network Layer] there is IPsec)
Teacher: no, it's wrong.
me: so Wikipedia it's wrong, RFC 5246 is wrong, and you have right?
me: Ok. (aka fuck you!)4
For about 1.5 years on and off, we've been developing a system to rate tickets/requests sent to our team. We wrote it in Angular, and it turned into this feature-rich gorgeous application with custom-built graphical statistic tracking, in-app social networking capabilities, robust user profiles, etc.
Eventually, we no longer had time to work on it along with all the other applications we're developing. So we passed ownership of the app over to a couple of other developers on our team. You'd think that they'd just work off what we already built and keep the robust environment we created for them. But nope, instead of keeping everything we already built, they scrapped it all and started from scratch using React instead of Angular, and removed all of those robust features and turned the app into a shell of its former self. No more statistic tracking, no more social networking capabilities, no more fancy user profiles. Just a single page with a number representing how many "Good" tickets you've sent to us, and how many "Bad" tickets you've sent.
1.5 years and hundreds of hours worth of work, all gone and replaced with the most rudimentary basic React app ever.2

I am going to an AI conference in Berlin (which is kinda far away from me) next month.
I am just learning AI & ML and integrating them into a personal project, but I am going there to meet people, learn and gather info.
Do you have any advice on how I could network with people that are masters in this area?11
College. The head Prof of the IT department tries to open a site without even looking at the networking icon, which says disconnected, meaning that the Ethernet cable was unplugged. Tries to refresh a couple of times.
Goes off to find a lab assistant.
Assistant comes is, plugs in the cable.2
Well I probably should have been more prepared for this, but i was able to backup, upload and transfer my websites from my own server to my backup host provider while my ISP has been down for the past couple hours. Fun stuff.
Docker's encapsulation is amazing! I don't have to know anything about networking to get a swarm running with some demo services all talking to each other and central logging and... oh I fucked something up... better read about networking so I know what I broke1
Linux has been around since back when dinosaurs punched holes in cards, but for some reason it still takes a few hours of googling and error debugging to do something as basic as connect to a wpa2-enterprise wifi network.
What the fuck? Where's the "connect to any standard work or school wifi network" command line utility distributed with all os flavors? Why can't I just put in a username and password and be done with it instead of sudo editing networking adapter configuration files manually?3
In follow up to my last rant.....
A friend just informed me that I should enable dhcpcd to get networking in arch...
I was typing dchpd......
why don’t I read things more carefully
I’ve been at this for hours and I just installed ubuntu alongside arch because I need my laptop for tomorrow. Ugh1
You can connect to Docker containers directly via IP in Linux, but not on Mac/Windows (no implementation for the docker0 bridged network adapter).
You can map ports locally, but if you have the same service running, it needs different ports. Furthermore if you run your tests in a container on Jenkins, and you let it launch other containers, it has to connect via IP address because it can't get access to exposed host ports. Also you can't run concurrent tests if you expose host ports.
My boss wanted me to change the tests so it maps the host port and changes from connecting to the IP to localhost if a certain environment variable was present. That's a horrible idea. Tests should be tests and not run differently on different environments. There's no point in having tests otherwise!
Finally found a solution where someone made a container that routed traffic to docker containers via a set of tun adapters and openvpn. It's kinda sad Docker hasn't implemented this natively for Mac/Windows yet.4
Linux networking: A tragedy in three acts
Wherein the system administrator writes their /etc/network/interfaces file as is the custom.
Wherein the kafkaesque outputs of basic networking commands threaten basic sanity. Behold:
# ifup ens3:1
RTNETLINK answers: File exists
Failed to bring up ens3:1.
# ifdown ens3:1
ifdown: interface ens3:1 not configured
Wherein all sanity is lost:
Last week I wired up my home network (including custom modem and routers) myself, because the stuff my ISP wanted me to use was garbage.
Luckily Germany has "router-freedom" so ISPs are not allowed to force us to use their device to dial into the network.
I did everything myself, because the 'technicians' they kept sending me were just idiots who didn't know anything, considering the highly paid job they are doing. Usually they told me, to get the device from my ISP, because my "Router" (actually a business grade, standalone Modem by Cisco, to feed my Router) didn't even have WiFi ( lol ). Also all Technicians didn't arrive at the agreed date but at some other time. I wasn't able to wait any longer.
So I did it myself.
Consider me something more like a student of theoretical computer science. Not actually supposed to be experienced with hardware stuff.
The ISP is serving me with a DOCSIS 3.0 Network based on the television cable network in my city. For some reason they are providing the internet-access to only one socket in the apartment, which has a rather uncommon "WICLIC" connector. After having trouble getting an adapter for WICLIC to common coaxial F-Connectors (used by every DOCSIS-Modem), I made one myself.
After setting up everything (not that hard, once the connectors fit) my modem told me, that, while I'm perfectly connected to the ISPs internal Network, I still can't access the internet.
So I called the ISP...
After getting ranted at, about that what I'm doing is illegal and only certified employees are allowed to do this and I will break more, than actually do good and that I can't just connect my own "Router" (again I needed to correct her: Modem) I hang up the phone.
Also she accused me of hacking their devices because I'm not supposed to see my IP address... (My Modem told me on its web interface. I didn't even need telnet for that.)
I went to the ISPs head office, told the first desk as many technical terms as I could remember and got forwarded to something like the main technician.
He was a really nice guy. The only sane and qualified person I dealt with at this company. He asked me for my Address and Device Model, I told him my MAC and last internal IP, I had seen and he activated my internet access within a minute.
We talked a while about the stupid connector that ISP is using in the homes and he gifted me some nicer adapters to connect my modem to the wall.
Why do ISPs hate their customers that much?2
Best: i learned a lot this year, cant really highlight anything but i got better at networking stuff, im happy about that
Worst: using xamarin forms probably, it was a literal hellhole and midway through the project microsoft abandoned winphone so there was absolutely no reason to keep using that shit
I saw a recruiter rant on linked in where they can't figure out why candidates won't give out current salary or they won't represent. If you have been working in and learning hot technologies in your current job but you know you can earn more why would you want to be represented at the lowest possible rate? I say give them an acceptable salary range not current rate. I am seeing why devs are moving toward meet ups and networking to get decent work.1
I'm a computer engineering student.
I'm very much interested in Systems and networking.
That's why I was thinking of persuing cyber-security as a career option.
But I'm not quite sure if that is a good choice.
Also I don't know how to proceed in order to achieve excellence in cyber-security.
It would be a great help if you guys could help me.
Was asked to crimp a simple Cat5 LAN cable in today's networking tutorial class. Little did the lecturer know I had been doing that (usually Cat6) for almost a year. Walked into the class 30 minutes late, terminated both sides within 5 minutes and just sat there helping my friends for the rest of the 2 hour class...1
Linkedin looks like some devs went to Facebook, right clicked, saved a copy of the webpage and just edited some of the text. Why do we need "Like" and "Comment" features?
It was fine when it was just a professional networking site. Boring, sure, but at least it did the thing it was created to do.
It's all very cringe now.
PS I got my current job and will probably get my next job through Linkedin, but it still makes me cringe5
I'm too young to have taken my last job...
Enough with the jokes. I have been networking with a lot of people through the years of working at companies and that paid off.
When people trust you for your knowledge, then it's normal to attract business offers. Also, you can partner up with people. That's how my last job started and is still going. At a previous company, I interviewed a guy who had the skills and motive to replace me, but he didn't get the job cause my boss was stupid (he was lucky not to work there, for real).
After I left, he called me to offer me a partnership. One year later and we are killing it, became good friends too.
It must be good to at least know computer networking?! I remember nothing about these TCP, UDP, whatever the fudge protocol shite. I don't remember these megabit and megabyte things. All I do is code from one end to another. Anyone else watched Eli The Computer Guy's series?2
What is the social networking programmers use to communicate.
So what program do you guys use to communicate? Something that I can drop here and not behing spammed. Time to start creating my own network arround you guys... You know, smart people.11
Fighting against a occasionally occurring bug, in a networking, multithreading, server-client game.
Thanks to the good excellent front end each client only uses around 20% of my cpu and ~1.3Gb of ram.
Shit happens when you join the development late and your partners code happens on-the-fly.
Maybe redoing it from scratch with something else than JSwing could improve the performanxe slightly
One of my trainees some years ago was too lazy to process his networking homework, so he just modified the binary of that cisco tool he would have to use and removed the password prompt at all to access the solutions.1
I was having internet issues -
I'm running an nongenuine iso of Win7, and installed the driver for my wifi adapter (ralink)
i performed this process three times after it one day stopped working.
i stared directly at my wireless networking button. which wasn't lit.
and then i continued searching for help on my second computer (hp stream, i cry)
and then it fucking hits me
the networking button
so i pressed the button, what you're thinking happened happened, and i both had all the motivation in the world to continue living, but simultaneously wanted to die a thousand deaths becaus I was that fucking STUPID.
have a blessed night,
write code like God's reading it ,and satan's using it.4
My office WiFi is freaking fast upto 25mbps, should I download Torrents using it. Is there a possibility that corporate networks are under more surveillance ?7
School decided to shut down their WiFi for "security" reasons (Everyone used a VPN and they were dumb fucks at networking, blocking sites like Google for having an invalid SSL certificate).
Now I'm forced to use my mobile data to keep using my Arch Linux laptop D:3
So I just started watching Eli The Computer Guy's videos on networking and I really like them so far(only on the introduction so far though), but I was a bit confused about some of the stuff and I thought to myself that some of this might be obsolote or not so much in use these days/different. So here are some questions(now bear with me, I'm still a noob to the whole topic of networking):
-Are Eli's videos on networking obsolete(besides the speeds that he talks about), what you recommend some other tutorial, if so which one?
-Is a switch necessary for a small network?
-Do we still connect routers to modems or do we just use what we refer to as a router(a mix between a router and a modem -> gateway/gateway router)?
-Can you connect an ethernet cable to your router/gateway?
-So according to Eli if you have multiple routers they make seperate networks that cant just be acessed from each other, then how come it be that I can access my rasperry pi when I'm connected on the network of one router when the raspberry pi is connected to the network of another router and how come it be that once you have the wifi password you can connect to all of them?14

"We've got a new opportunity for you."
I'm a fucking rookie. I didn't know the meaning of this sentence. Suddenly, I become the "IP PBX expert" of the society.
"-Okay, it's some networking shit, I thing I'm good at networking shit. Piece of cake.
-Okay great, you have one month to learn how this thing works, because we WILL provide this kind of service."
I spent one month learning this shit on my free time, printing RFCs and living in the fucking MATRIX to not fuck up on the very first day doing that, just in case something on the customers' network fucks with the PABX or something like that.
Oh yeah, I forgot: I'm paid 80% of the minimum wage because I am actually not qualified to do my job and I'm spending one week a month to learn how to IT (some french weirdness I think, if not, maybe it's the germans' fault. Also yes, 100% legal).
Today, they announced me that they "changed their mind".
Not really a rant but a question:
I just got accepted into a coding bootcamp. Have any of you been involved in one? How was it? What would you do to make it a better experience throughout? Any advice or suggestions?
It's full time, six months long and I start in October and I want to make sure I make the most of the experience and absorb as much as possible.
Fucking job recruiters or whoever the fuck.
If the first line on my resume is under "Objective" and it states, "To obtain a job, internship, or Co-op in the field of Networking, Cybersecurity, or Administration." You can clearly see the world sales and customer service are not in there.
If you take 5 seconds to read that or search for the words customer service or sales YOU WON'T FUCKING FIND ANYTHING.
SO WHY THE FLYING FUCK DO YOU CUMBUCKET FILLED PIECES OF SHIT KEEP OFFERING SALES AND CUSTOMER JOBS TO ME.
I even got a senior sales position before. :|
Yet I can't even get a call back from an internship that's related to what I want to do lol. Smh.1
Learning programming, networking, robotics, and other technical skills are very important but do not forget that these are future working software developers.
They will need to know a lot more intangibles. Like effective pair programming, performing proper git pull requests and code reviews, estimating work, and general problem-solving skills and more.
These people will be learning technical skills for the rest of their life (if they are smart about it) but what can really get them ahead is the ability to have good foundational skills and then build the technical skills around them over time.
Okay so I need someone to tell me if this is what its like programming for a Superior at an actual job. Background information, I go to a highschool where Im learning IT fundementals, Programming, and networking.
So then my teacher is like "can you add a number showing what percent its at?" and I was like "yeah sure" so I did it, and today I showed him and he was like "Can you make it to where the percent is in the center so you can see what its at the whole time" so I obviously replied

I see here so much motivation in work you are doing and i am here standing without any inspiration, motivation in learning things, i can't stay focus more than several minutes reading interesting topic. I use to simulate and create different network, doing great stuff (i am or maybe was addict for networking) How you guy/ girls can do it? Some tips would be awesome.
Finally learning Kali linux. And one of the few who plans to use it legitely. We rely on network setup for our system for the computers and printers mainly. sometimes stores change stuff without telling us and my networking knowledge is rather limited. i think learning stuff in kali will let me learn "backdoor" ways of doing things when conventional methods don't work.
Ok so Swift's module system creates implicit namespace, meaning gone are the days of Objective-c frameworks / classes having prefixes.
I get that, and its a great advancement. But when I'm using 3 different social media SDK's, a networking library and some persistence cocoapods and I have to use classes called "AccessToken" and "Manager" ... come on guys, name your shit better.
I'm looking at you Facebook and AlamoFire!!!
Just heard about the WPA thing.

I feel sorry for your 4 years of study.2
So recently I saw a rant about a e2e encrypted social network and started to consider the idea, what do you guys / brother in code think about it2
I know very little about networking.
So I've got this modem and I am trying to configure it, I am supposed to access to it through a web browser using its IP address. I pinged the broadcast to find the IP, but when I am trying to connect I have a nice "connection refused". So any ideas ?8
Is it all worth it? We feel its freedom, We feel it's just me and my phone or my PC. Is it? Is it that private? That camera you have on your phone, what if someone is watching you right now? That microphone you have, what if someone is listening to you right now? Those stuffs you Google, Those sites you visit, you're tracked, you're tapped. Ohh Incognito, Good Luck, there's no such thing called Incognito. Is it all worth it? In fact you're getting so much out of it. Is it all worth it? Or Am I just too obsessed? Is this Internet really that free?
It's freedom but you're compelled to use. Its freedom!
So I guess this doesn't really fall under dev, more web and net admin, but here it goes.
I am trying frantically to migrate our (@Gerrymandered and I) website from a hosted solution with Namecheap to my new personal badass server, Vector. The issue is that I need to host multiple subdomains under one IP. I learned how to use apache2's VirtualHost feature, and eventually made them all work. But now we need to get our 3 year SSL Certs that we already paid for working. Try to get ssl pass through... Nope. Fine, just use the VHost then forward it unsecured to the local ip which only accepts connections from the Apache host. But wait! I want to access my ESXi config page remotely too! Good GOD it is a pain in the ass to get all of this working, but I somehow did. Evidence is at https://git.infiniit.co, which is hosted on the same network as the ESXi control panel. *Sigh of relief* now I can sleep right? 😥29
I know many of us perhaps don't get too involved with hardware and especially not with professional network installs, but I wanted to share this YouTube channel.
I've watched a couple of videos and have picked up some tips. Even if you're not interested in networking, this guy's problem solving ability is top quality.1
Changes demanded by client #140572:
* When a user comes to the web app from mobile, use section scroll (i.e. take control of the scroll for them and scroll them to the next section automatically) instead of letting them scroll independently.
This comes from a client that is basically the biggest networking company in my country.
WAY TO GO FUCKTARDS, DO YOU -REALLY- WANT 90% OF YOUR USERS TO ABANDON YOUR LAME ASS LANDING PAGE?!
MQTT - all I used to know about this is its name, untill few months back a client sent us some requirements which included MQTT. I opened its specification and I was fucking shocked! I am implementing almost similar protocol in most of my applications (which needs subscription based service) for last 3 years. I have developed IoT apps, remote monitoring systems, HMI systems using the same fucking protocol! Even I had implemented the same thing on HTTP using long polling a few years back!!
Now I feel like open sourcing my protocol. But I don't know where to start. Any help please?1
Speaking with my former coworker about networking:
Me: Coaxial uses the Ethernet layer two protocol.
Coworker: No? Coax uses the RADIUS layer two protocol.
And this guy was my "superior."
I programmed an app I've been working on. It sends ICMP packets out...the message I programmed was "One ping to rule them all".
Oh yes, I am the Ping Master ;D2
i had a project in a networking class where the provided code was meant to act as a proxy (aka just passing bytes around), but because of the implementation, every byte had to be a valid unicode character
anyway lotta people were frustrated so we asked the course staff and their response was basically "we wanted to support python 2 and 3"
Really wish there was a site that contained a library of fundamentals of development processes like basic networking, specific game mechanics and the such.
I don't mean show code but explain some of the maths and algorithms that go into the programming itself.
If I had the time I'd build it...6
Are email-only signups secure? What if I created a signup form where all you enter in is an email, and in order to log in you must click on a verification link in the email.
I would think this would remove the "stealing passwords" problem with many social networks, because there would be no passwords in the first place. But would there be a way an attacker could hack this and access accounts? Idk6
I don't want to learn every detail about networking, but I do certainly want to learn enough to make my software more robust and secure.
On a 2 week CCNA networking course. I can never look at any network the same again, and I have never had this much respect for the amazing protocols2
I have to take UDP and add packet ordering, filter in, and resend and some form of handshake, because client couldn't figure out how to change the port from UDP to TCP and refused any help2
Firstly update materials, because on our school, they are old. Also our infra and internet. My school focuses on Cisco networking and every fucking time it does not work.
Fuck DS-Lite with a rusty rod covered in sand. Also fuck 4to6tunnel.
Boy I really need to take a networking class, this is driving me nuts
So just a normal rant here. .. it was one of those moments you find in yourself in sometimes. You get so caught up in thinking you know everything that you can't implement occams razor into your everyday work routine anymore. You've worked with so many complex workarounds that when you are faced with a simple problem with a simple answer you can't see the blinking neon light shouting at you anymore , and you can't here the bells sound anymore. ..
My rant is about Me vs the infamous mikrotik router. Something I had to set up. Something I had to login to setup. Something I've done so many times before but this time , my inflated ego and overbearing sense of grandeur just could not figure out.
Class how do we login into a router? Well find your gateway and type that sucker into a browser and you will be on your way ... well that's the answer right there. But since I thought that my router was connected to three dummy switches that it would affect anything or the paranoia I had that my isp somehow disabled any connections to the router at all or that I and to open a new port to connect to it or use winbox to connect to it using only the mac address or ssh into it ..would work ...I didn't try using the tried and tested way of doing it.
I wanted it to be an adventure. I wanted it to be a problem to solve so I shoved the ordinary answer out of the way and used other methods to try and connect to it...
All I had to do was used Nmap to scan the gateway for open ports and realise to view it in the Browser on port 8080 instead and finish my journey ...
I was looking for a dragon to slay , a maze to conquer, glory at the end of my mission ... when all I felt was a sheer sense of idiocy.
I've been developping some software so an entire debian OS gets bootstrapped and installed with all the desired software with the help of puppetlabs software...i need to prepare a server that can handle virtualization and be fast at it. So all the goodies a decent server needs, the apt, caching, networking, firewall, everything checks out... I want to test kvm virtualization... Doesn't work. Wtf? Spend a decent amount of time figuring out what the hell is wrong... I finally dzcide to think 'what if my buddy accidentally gave me a bad mobo'...
$ grep -e (vmx|ssm) /proc/cpuinfo
I feel so stupid to not check the mobo virtualization capabilities.3
So being in ops, I have certifications in networking and Linux, and am currently working on my Certified Kubernetes Administrator exam.
I've been talking to a few "professional" (they have jobs) devs that I personally know, and with the exception of 1, it seems like version control, automation, networking, and server related tasks are beyond them.
As I want to get into the dev side of things (devops preferably), I feel somewhat overwhelmed at some of the requirements of the job, especially knowing that I cannot take too much of a pay hit as I have a family to support.
My question is this, based on real world experiences with hiring, how much weight do you think knowing your way around networks, cloud, virtualization, servers, and all of the other things ops does when it comes to getting your foot in the door for a dev job?
I've casually looked around, and it seems that getting the foot in from this side is almost impossible.2
I just got a free invitation to a HackerX job networking event. Has anyone ever been to one of these events? Is it worth it to go?1
There is no joy in life
So I finally managed to set up networking on my 3D printer's raspberry pi: now it can connect to my phone's hotspot or to my uni's wifi network, depending on which is available.
Then I set up OpenVPN, using a remote server as a middleman so I can connect to the printer remotely and start/stop/monitor prints from anywhere.
Everything works great, except for one thing: whenever the Pi connects to the uni's network first, OpenVPN fails to start and connect to my server, rendering the printer unavailable (unless I use an ethernet cable, but that's not a viable operation since I need to lift the printer, and it's heavy).
The only for it to work as intended is to either:
a) keep my hotspot active (which kinda defeats the point), or
b) let it connect to my hotspot first (so that OpenVPN can start properly) and then turn off the hotspot, allowing the printer to reconnect to the uni's wifi and reconnect to my vpn.
Why won't things just work the way they're supposed to? 😭10
Can someone explain to me what is meant by, "full stack," nowadays? I see posts by people saying they're, "full stack," but don't know anything about Linux, networking, databases, or daemon configs.
How can you possibly call yourself a full stack engineer if you don't know anything about infrastructure?11
Spend 1 hour learning to configure networking interfaces via command line on an ubuntu VM for home use.
Can't ping anything.
Double check /etc/network/interfaces, restart box, check loopback interface functions, check physical cabling.
Realize that VM is attached to a separate virtual switch.
Virtual switch is tagged for Vlan 2, connected router is a flat topology.
Exam in networking in a week. It's a group project with individual presentations. No one but me have done any work until now, so I threatened leaving the group and do everything myself, which I am able to, since I have a lot of experience with this before university.
All people reacted but 1. He hasn't returned any messages nor met at campus in over a week. How should I react to this issue?4
So I installed FreeBSD beacouse I was interested in jails and bhyve on my main machine. Now I have semi-working setup and can't figure out how to run jails or Debian in bhyve. Oh and Docker doesn't work beacouse of some strange bug that no one can find solution.
But the whole system still looks fun. Just turns out there is a lot to learn, for me, about administration and networking.
Interplanetary networking and quantum computing 🤔 something to ponder about... I want to be there now!
Why must some of our clients have 2 cups and a string isp. Your business is in fucking Chicago, you have many choices for better connection. Your competitor, who we service, never had networking issues and theyre only several blocks away from you...... I hope you burn alive at the same speed as your network connection.
Co-workers conversation about the new Google Pixel... "I won't get it because they steal your soul, same reason why I don't have the iPhone with the finger print.. they want to have all your information... blah blah..."
I laugh, because they device doesn't matter... your info gets stolen in transit... so all your snap chat, IG DMs, and all of communication potentially at risk to be "stolen".
Example, Gov't splicing into underwater fiber optic cables and redirecting traffic to a data center...
Understand the tech.. please.3
Hello, i am new here and I saw a lot of great people with good advices, so here I am. I am new in sysadmin field and i need some advice from you. Now I watch CCNA videos and practice in packet tracer. What do you recomand? Videos/ programs/ OS . ( i am a computer science student).4
Hey all, I'm curious for your opinion on this one. I've got some smart home devices (e.g. Hue lights, Nest Protect) and lately I started to think of the best way to protect them. Now I did see this project on Kickstarter (https://kickstarter.com/projects/...) and it seems to be a nice and easy way. But still, you don't know what they'll do with your data.
Would MAC address filtering in my router / modem not suffice for protection?
Let me know what you think :)5
Looking to get into networking and security to help with my code in general. Any of you dev have a good recommendation book wise?3
Network management from the terminal is such a pain in the ass on linux! Far too many different config files in many different places, and I have no idea which works with which!
Just now I managed to fuck something up in my RPi's config, so I don't have wifi access anymore and I didn't have time to find its ip address while connected through ethernet :/
I'm working on a concept for an efficiency/speed focused networking project.
Any recommendations for low-level languages that support networking that can be run on both windows and Linux with relative easy?
Thanks in advance!6
As a developer for cloud based applications, if I get errors that are weird or I've never seen before it's always networking issues.
Walking past a conversation with people and over hearing the term CNN, thinking its about Convolution Neural Networking. Long story short. Im standing here between people discussing news resources. Fml
Being a full stack developer within a company that has separated departments for each stack can be very frustrating, especially when it comes to just a development environment.
Although my main role is a backend PHP developer, there are times where I need to configure or install something in a development server. But I have to put in a request to the networking team every time I want something done. Personally I find this to be very inefficient and wasting my time and the networking teams' time as well.
An example would be I want to install Supervisor to have a process restart in the event that it dies, which I explained to the networking guy. But the networking guy says that they don't want to install it, can just make a systemd service instead. I said that is fine and asked if he could do that or can I do it myself. Then he wants to know why I want to have a systemd service installed even though I just explained it to him!
Though I guess I'm always going to have this kind of issue with networking teams.1
I have several stories from the same mentor. Programming, networking etc...
2 of my biggest lessons from him:
1. "If it has to be done more than once, it can be scripted".
2. "He who controls the network packet wins".
I need some help on figuring out what to major in
My options are:
-Computer system administration
Does anyone actually compete in online hackathons? Honestly it defeats the whole networking and socializing aspect and just seems like a way to fool developers into creating free products using company apis...3
!rant / Joke
RoR dev (Me): Damn, I gotta learn more about that routing DSL... Shit's powerful.
Networker: That sentence made zero sense... Did you just use technobabble? Go to marketing you dweeb.
Well, Matz really trolled the networkers there...
DSL(Ruby) = Domain Specific Language.
Routing (Rails) = Defining URL Patterns and assigning them to controllers.
Networks(As far as I understand, I only know the absolute basics there):
DSL = Digital Subscriber Line
Routing = The act of passing a packet through another network
"Oh, you can't help that," said the Cat: "WE'RE ALL MAD HERE. I'm mad. You're mad."
And the weird penguin building a rails app is mad too I guess.1
Was told the following by an "Information Security Professional"...
"RFC 1918 addresses will not follow a default route, default routes are only for internet bound traffic and RFC 1918 addresses are dropped by any router without an explicit route."
I honestly do not get paid enough for this.2
Built a pretty cool native feeling web app with Socket.IO for event schedule management and networking. Pretty awesome to see what can be done with modern web tech!
There are no words for my annoyance with linux right now. I have spent way too long debugging the networking and still can’t connect to the internet. I’m just trying to setup a static IP on my local network... IS THAT TOO MUCH TO ASK???3
Fuuuuu Proxmox Fuuuuu Networking and Fuuuuu me being a Devops Noob
I dunno why it works again but it works again and it hadn't worked before and it just doesn't makes any sense !!
-- Edit --
Never rename a Proxmox Node ever kids!
This AWS migration is a pain.
Neither of us know anything about networking, and we can't get any help with it.
Talk about bashing your head against a wall.
I was trying to set up my own "cloud" for iot experiments. I planned to use Intel Edison with mqtt broker (using mosca) and a node js app for providing API for mobiles and browser. And also to do other book keeping.
I spent the half day trying figure how to expose these servers to internet.
I configured ddns in noip.com and ddns settings configured to it in my router.
Port forwarded to the local server services I needed.
And then tested. Worked perfectly on any device in my router connected network. Tested on mobile network. Bam! It fucking doesn't work.
Then connected another router.
Double port forwarded. Again worked perfectly on router network. And failed on mobile.
Tested if ddns is right. Did nslookup it was fine as fuck.
Then disabled port forwarding. Did dmz. Nope. Nadda. No luck.
Then scratched my head so hard that I lost more already losing hairs.
Then remembered about router hardware firewall. Disabled it.
And there it didn't work.
My dreams shattered like a fucking deer hit by car on highway.
Then I see the IP pointing to my router in nslookup. Its 172.20.xx.xx. Its a fucking private IP.
My Asshole ISP is running another private network behind firewall. Which I fucking can't port forward
Now I think how much of a noob and idiot I am. Fuck this shit. Fuck all of these shit.
I am going for SaaS option for mqtt broker.
(Or help me?)
Fuck your firewall.
(PS: I had test the next day. FML)2
Is data sciences/ML/AI a subset of web development and networking ? Most of the time i feel people need to know web development tools and languages to be successful in this ML/Ai/datasciences career. Should one go learn web dev first?12
How fucking hard is it to find a good tutorial or at the fucking least a well documented resource for setting up a full-mesh VPN in either C or C++?
Any suggestions would be welcome.3
Discord server under development for software engineering, cyber security, networking, and IT talk in general. Looking to meet new people and talk :). @ me if you're interested in testing it.4
Anyone have ideas for an independent study cs project? I'd like to do something advanced(I have a full semester to complete it). I'm pretty interested in anything dealing with ML or networking. Comment if you have any suggestions. Thanks!3
Well, after almost a year of doing self study and what not... I decided to enroll in a bootcamp. Partially to help keep me accountable, mostly to help with networking and making contacts in the industry around me. I'm really stoked for it in spite of skepticism. They do offer guaranteed job placement if you finish the course, which was a major selling point for me. I'm curious if anyone on here has attended one? Thoughts? Success stories? Horror stories? From the research I've done, seems like you get what you put into it.
If I'm at the library.
And there are Ethernet ports.
Desktop computers are connected to it and working fine.
But when I try to unplug it and connect my laptop with it it's just doesn't work, as if it says there is no Ethernet connection at all.
What are some of the reasons for such thing?
Do I have to look up specific IP configuration and configure it on my laptop?
Do these windows domain system matter?
How can I get started figuring why it says it's that there's no connection in the first place?
The librarians know Jack shit about why it's not working.
And I can't find the technician contact address to ask him/her/them directly.
WiFi works fine, but slow, Ethernet connections has a gigabit connection. (I believe that should explain why I want to use that instead)6
Right before I became a dev I was in school for networking, and even got to do an internship with the networks my department of a school but then decided to do the codez. It's been 2 years since and my dad still thinks I do networking things since he hears me mention servers . (I'm a backend developer)
The fucking Unity Transport Layer API documentation is horrible! There's a bunch of information missing, and whenever I try to send data I just get a "NoResources" error. All the docs say about that one is: "No internal resources ro acomplish request.", nothing on forums or google... Worst part is, I've not even started dev that long and Unity has already given me quite some trouble. I hope that's just inexperience, and not Unity being a bitch.2
My boss (in a good way). Both in my workplace and out of the work place. He's given me a lot of fantastic opportunities to learn on his time. He has encouraged me to do so because he saw my passion and love for programming. I'm incredibly lucky and blessed beyond belief to have him as a friend, and my manager.
He's the Senior Director of Network Services. So anything dealing with networking he's in charge of.
@Work: Every new project, we need a new server for CI/CD...
Whiteboard + bets on how many weeks it will take to get some servers provided.
tired of finding a name for my social networking platform. wanted to name it ripp.pl but richard branson invested in some patented product called ripplier2
Trying to run the examples of Boost networking in two programs with QtCreator. Same Qmake file, one program compile, the other has a linker error. Why?????2
Testing new server deployment in test env all works, then production it all breaks down. Network didn't allowed the right traffic. Took me whole week to find that out. Until some networking engineer said, you know there is a firewall between those networks?
I'm looking for a project idea in cyber-security...
I'm good with x86 assembly, c, c++, python and shell scripting.
I'm very well versed with Linux operating systems and basic networking stuff.
I'm willing to learn new concepts11
So, I know that RIP (Routing Information Protocol) timers used to synchronise although they were supposed to be started at a random time. My question, why and how did this happen?
How reliable or better freebsd is? I was thinking to use it in production server instead of ubuntu 16 LTS. I've heard it has pretty good networking stack and whatsapp uses it in their prod machines.6
Does somebody have any experience with LXC/LXD containers on servers? I basicaly want all the services separated, but still have an easy way to manage the networking/routing for all the services and containers.
Any reference, guide or tool that helped you in master this subject?
Thank you in advance!5
Is there any place like Dev rant but for networks ? And anyone know how to make the smallest lamp stack. Any help is appreciated. :)10
I am in final year in computer science and i have to do a license. I know for sure it will be something about networking( not programming)(I am junior sysadmin in a company, i told you that so you can make an idea about the field). I did not find any great idea until now. Can you help me with some ideas? Thank you.
So let's say a client wants a social networking app. This obviously requires a back end. Who pays the server cost?4
List all commands for troubleshooting networking issues! (For Microsoft) Go!!!! (I feel like I'm forgetting some!)4
I would end up on top of any other trend thing needed by humanity.
- building better AI's, building better robots
- neural networking
- quantum computing
- robot dating service
- artificial life
- holodeck design and construction
- free energy (any kind)
- running a private space shipyard
- research into new and unknown technology
And last, if nothing works, I would open up a deli on Mars. The robots would make the food anyway, I would probably only program the menu and fix them when they malfunction.
Any advice for the CCNA exam? I've been through the cisco online courses and use them for reference. I know Todd Lammle's guides are pretty good too. Any extra texts/resources I should take a look at?
I feel my weak points are:
IPv6, NAT, ACL's, and Class A/B subnetting.5
I wanted my MySpace and Xanga to look better and function better than everyone else's.
I created a very basic directory on my xanga linking people's real names to their respective xanga for my group of friends. I started getting requests to add people to my directory. All my friends would go to my xanga first so they could easily find our friend's xangas.
I created social networking.
But it felt good knowing that I made the Internet a bit easier to use.
Any networking guru's here? I have a practical question regarding network controllers (SDN)
Help please. Stackoverflow is not helping 😫
Is there an equivalent to Robert C Marin's book, Clean Code for Network design? Or do you guys have any recommended booms inters of network and server infrastructure?
Any ideas for experiments with data from WiFi monitors? Using aircrack-ng / airodump. For IoT themed UGR project
There is a feature that i have been wondering about for a while now for this app. We all know the stackoverflow community can be toxic and horrible, but sometimes I have questions that aren't right for stackoverflow and would like to be able to ask that here. I am a 2nd year Computer Engineering student, and I know I speak for many of I say you are very confused at this age. I would love a section where you can ask carreer questions and stuff like that, not coding stackoverflow type of questions. For example currently I am wondering, should I move into the networking direction or AI. I am currently doing 2 CCNA courses and I love this, and there is a feauture for this, but IA also breaks my brain and I would love to take it further. Programming is my life, and in my holidays I code, when doing a project for class I would take a break from my programming project and work on my own code or play my favourite game Screeps, but this CCNA course is amazing and I also love that. Both AI and networking have futures in this world, but now is the time for me to pick and start to work on it!
Once again the department head fucks up my degree plan!
I'm getting my associates degree in Cyber Security. So we have to take networking courses and what not. So my institution recently became a Cisco certified teaching establishment or something along the lines of that.
The department head said that everyone who was enrolled in classes before the upcoming fall semester would have to take the new Cisco networking classes and not switch to the new degree plan. (We would take 3 Cisco classes instead of the new degree plan which is 5 or 6) so we planned and register for those classes.
Now he comes back and says we don't have to take those new classes. So it just fucks up the whole shit.
Switching to the new degree plan would add like 3 semesters to my total semester count and I'm supposed to graduate. August 2018
Fuck this new shit. Even tho I need Cisco.
I plan on taking The Cisco classes after I graduate with my associates degree while I'm going to a university for a dual degree in Software Engineering and Cyber Security
Network switch or Ethernet switch can act as a lan? I mean can they do all stuffs like sharing files and data between two systems?1
Hey guys I just wanna start to know about the networking and connections from the beginning, 'cause I've got some information about them but there aren't complete enough. Could you plz suggest me some sources or paths to start studying about'em...?!
Had to do a presentation today about os hardening on embedded devices and wanted to do a quick demo.
Forgot to make a sacrifice to the demo-gods and had to pay for it, nothing worked and i was struggeling with networking issues throughout my presentation :/
Worked perfectly 10 minutes ago as i was preparing and perfectly fine afterwards as the presentation was over...
Feeling really down and frustrated right now
What are your experiences with the demo gods?
Guys, i am a beginner in networking. I want to create my own cloud computing server - (IAAS). Currently, I want to provide storage to the users.
How should i proceed.. Any site link or guidance? Thanks in advance.1
