Yet another commercial seminar upset I won't give up a day of my time to fly to the UK to speak at the event for no payment or reimbursement for my travel.
But of course I should think about the exposure and networking opportunities! 😕

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.."
*Get transferred*
"Hello this is the supervisor"
Me: "fml"
"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 -
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 listening10 -

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 -

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.

So...
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 -

Android Dev: *Replied with screenshot* "Failed to load resource: the server responded with a status of 503 (Service Unavailable)"
Network admin: that is a known issue. *Replied with Wordpress Links.
Android Dev: why is github working outside our network then?

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 -

A third party manages access to a web application I’m supposed to begin using. While accessible from the Internet, they whitelist IP addresses, so it rejects the login credentials if not coming from a whitelisted address.
I provided my external IP address to their support team but the application was not letting me in, so I called their help desk. A support technician said that my IP address was 10.x.x.x, a private IP address. I’m not on the same network as this application, so I did a quick check and realized they are reading my internal IP address from my X-FORWARDED-FOR (XFF) header (yes, my employer exposes this).
I explain to him that the application is incorrectly reading my external (connection) IP address and is instead reading my internal IP address from my XFF header. I also explain that it’s not a good idea to add a private IP address to their whitelist as it somewhat defeats the point as anyone can assign that IP address within their network and expose it via an XFF header.
After talking to numerous support personnel, I came to the conclusion that not a single support person on their team understands basic networking and private IP address ranges.
I finally just said, “Fine. Go ahead and add my internal IP address but keep in mind it will change a lot.”
He then proceeded to “explain” to me how my IP address is assigned by my ISP and should change very infrequently. I explained to him that the IP address their application is reading is actually assigned by DHCP inside my network, but I was clearly wasting my breath.4 -

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 -

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

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 -

Context: one of my dad's friends is a veterinarian and he's opening a new clinic. My dad is renovating the building and I'm supposed to handle the IT part (Ethernet cables, server, laptops etc.).
Last Monday I get a phonecall from the veterinarian (which I'll be calling boss from now on) that he plans to open the next Monday. I ask him what hardware is bought and if anything is already done. As you can probably guess, the only hardware bough are Ethernet cables (with no plugs) that my dad run under the floor half a year ago.
After a brief wtf?! I asked him what he needs. The conversation goes like this (shortened a bit):
> What do you want/need?
< Make it good
> What?
< Make it so that the network lasts for years
> Ok, but what do you want? Do you want cameras? WiFi? How many PCs and laptops? What software will you use for client/patient management?
< Yes, I want cameras. Look around and decide where would be best. Clients won't need WiF, so don't botheri. I think one pc and two laptops will be fine.
> Ok, what software do you use? What does it need on the server?
< Don't worry about that. I signed a deal for a monthly subscription. I got a special offer where if I sign it for at least a year I get 10% off.
// We had this conversation about 2 month earlier. I was against cloud software because internet here is flaky at best and if the company goes out of business he loses all client data
> Why would you do that? I told you it's a bad idea because [above comment]
< Yeah, but [his employee] convinced me. He said that with cloud he'll be able to check that stuff even from his home.
> I could've set it up so that he could do it anyway. Whatever, did you get an internet connection to the building?
< Well, I've been considering getting LTE...
> Stop. You already made one mistake. If you also get an unreliable internet you risk having to close the clinic when you lose connection due to storm.
// Here he tried to argue a bit, but I was able to convince him to not do the stupidest thing he could
< Oh, and can you make it so that when I'm here I have internet on my phone and laptop?
At this point I just wanted to smack him in the face.
Anyways, a week and a half later the clinic is still closed. Not just because half of the stuff needed arrived last Friday, but mostly because the building is not usable yet. The renovations on second and third floor haven't even started yet.
And there is still no internet connection. Last Friday I even went to a local ISP (with his permission) to get everything done and he just has to go and sign the contract. When I asked him today about it he said he still hasn't been there.1 -

Spent 5+ years tolerating the bullshit of this guy (ex boss) and looks like it was a useless addition to my network.
I always got high praise from him and my colleagues and PMs. However, that never translated to good hikes/promotions/any favours of any type. Except for one time I never protested this because I saved the mental stress for other more important things (and that worked out well for me). It allowed me to sort of strut about the place like I own it and that was cool.
But today I needed to encash a favour from this reptile. And it was trivial enough that I thought I could count on that snake. But he did what he always does. Offered a useless alternative to any actual help.
So he helped, tried 'his best' according to 'policy', but I have to refuse it because it's like asking for water but getting air in return. Fucking chode.14 -

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 -

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.1 -

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 -

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 -
Just noticed that, at my school, the "sysadmin" forgot to put the password on one of the switches. That means I'm gonna have some fun, nothing that will get me in trouble, I'm just gonna mess up with the config a little bit so that he understands he fucked up.
I'm pretty surprised that none of the students discovered this, but I mean, none likes IT at my school. And guess who likes it but didn't take that "course"? Me.

I am going to an AI conference in Berlin (which is kinda far away from me) next month.

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. -
Linux networking: A tragedy in three acts
ACT 1:
Wherein the system administrator writes their /etc/network/interfaces file as is the custom.
ACT 2:
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

I have been working on IoT projects for last five years. After using MQTT in many of my projects I have realized that there is a huge learning curve for the beginners to understand and implement MQTT in their projects. The packet structure of MQTT is complex and MQTT packets are difficult to debug. Also customizing the open source MQTT brokers are also difficult for the beginners, and sometimes even for the experts.
To make IoT and Messaging simple, I am designing a new protocol which uses JSON packets for data exchange and is far less complex than MQTT. I am also developing an open source project which will contain a server (with load balancer support), a python client, a Javascript client and a python based load balancer. I hope this project will reduce the development time as the protocol is easy to understand and the open source code is fully modular & easy to customize.
This will be my very first contribution to the open source community. Wish me luck! -
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 -

to;dr: I think I'm retarded. I don't know how to networking.
got Proxmox set up on my server... sorta. I suck at networking. I bought a domain name, and I'm trying to have each container have a subdomain of the domain name I bought. each container has a unique internal IP address, but they all share the host's public IP address. so after a couple hours of googling, I THINK what I need to do is run a reverse proxy server on the public IP and route each subdomain manually to an internal IP address with something like nginx..... or am I retarded?4 -
Network code is hard. Events come all the time and it's really difficult to account for all orderings and uncanny timings. Have you got any advice, book or paper about it that I should read?
I'm using node and websockets btw.7 -
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?8 -
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
wasn't
fucking
lit
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,

Don't you love it when a network library is advertised as easy to use and quick to set up but the lack of proper documentation escalates the issue to a weekend long adventure about finding out how to do shit?
The Github wiki is full of small use case examples but none explain how to use the lib from ground up and everything is handled by an UI-based helper scene which you can't use anyways since the whole thing is supposed to run headless.7 -
I found out why my local server kept going offline.
Due to living constraints, it has to be connected to the network via wifi. The cable connecting the wifi card to the computer appears not to work when bent in a specific direction...
Why can't cables that come with things be of good quality?2 -

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 -

I finally managed to get my Wireguard setup to work in both ways! Beforehand I could ping from A to B, but not the other way around.
A network 10.1.0.0/16
B network 10.2.0.0/16
(both actually use multiple /24 subnets, but I reserve a /16 for each site for the sake of simplicity)
Lots of fiddling later this is my configuration:
A interface 10.1.199.1/32
A allowedIPs 10.2.0.0/16
B interface 10.2.199.1/32
B allowed IPs 10.1.0.0/16
ping from 10.1.1.1 to 10.2.1.1 => 172ms
ping from 10.2.1.1 to 10.1.1.1 => 172ms

I have become the only thing I always hated in a developer. Building a project without a proper documentation.
As a solo developer in a company where I have to do database architecture, front-end, back-end, testing, NETWORKING (I am the most ignorant guy when it comes to networking), product design, there is no time for documentation.
But hey, I have structured the project, files and functions (with comment, parameters type and return type) properly and I understand what I've done even after 4-5 months without touching that specific project so I got that going for me which is nice... I guess.3 -

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...
Ruby/Rails:
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

None of the networking people want to handhold the company VP during the all hands meetings (several thousand people over Webex's high volume broadcast service), so they all fumble around when they get in there.
The company owner rage fired someone in the networking team for screwing up. He has done stupid shit like this all the time.
It's one thing if it was some other time. Right now, firing someone, especially without review or for something so trivial, should be a god damn human rights violation. I've lost total faith in my company's management.2 -

Okay so anyone experienced working with networking or VOIP applications are welcome to try to help me figure out a few questions I have.
1.) How do VOIP applications like Discord and Skype not have to require you to port forward before use?
2.) If I wanted to do stuff with sockets over the internet the user of the application would have to configure a static IP Address. but when Im using Discord, or a multiplayer game, or literally anything that requires connecting to people I dont have to configure a static IP for those applications but I do for mine?!?
3.) Is there any additional information I should learn about whilst trying to make my networking application (File Transferring application) work? or any links/PDF's I should check out?
These are kinda just things I haven't found answers to, and I didn't know where to ask.14 -
My high school networking project. I should resurrect it.

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.

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 -

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 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.
Tested
And there it didn't work.
My dreams shattered like a fucking deer hit by car on highway.
Didn't work.
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.

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!

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?

I wrote about Java sockets and networking a few weeks ago. As a follow up, how would you manage state in a scenario with a server and multiple clients? A few solutions I've thought of:
Making the client and the server share a common class that makes the both of them know what can and can not be done.
Having a "Message" class which will contain a static method for parsing a received payload and return a Message instance with intent and methods to resolve intent (i.e. sending data to the client).
Perhaps both concepts should be used, or perhaps none. I'd like to hear your ideas :)8 -

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.

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

I am working on an embedded system, a microcontroller-based design. The system has an Ethernet port. I am using NetX framework in the microcontroller firmware.
The DHCP Client is executed properly, an IP address is assigned correctly when connected to a router. I connect a laptop to the router using a LAN cable. Then TCP sockets behave the way they should, UDP broadcast behave the way they should. The only issue is, when I connect a Laptop over wireless to the same router UDP broadcast are received on application on Laptop, but data sent is not received on the embedded device.
Any idea why?
Platform:
Laptop is Windows
Embedded Device: Renesas S7G2, NetX framework.4 -
Serious question - how does one learn basics of higher level networking, beyond stuff I can mess with on my local machine?
Today, I was completely caught off guard when I had to set up BGP-based loadbalancing on a machine and I just... Didn't know how the whole topology looks or behaves...
Once I go beyond the server in the network, I tend to get lost. Especially around how routing works and stuff like that... All I know is my machine has one or more gateways to which it sends data going to specific network segments...6 -

Networking guys:
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 -

Soon launching a social networking app just for devs. Post Dev memes, Collab, rant, brainstorm over ideas, reach out to anyone for chat, post your cool devspace pictures and earn rewards. Stay tuned!
Ps- I know there are many similar platforms, this is just a project I developed learning coding app development so just don't brag me about the concept. Although, a better UI/UX never hurts!
The project is fully coded by me and am open for Sr. Devs collabs for the project.16 -

I've never used Python much, but my network class had an assignment to make a program that would convert a physical MAC address to an EUI-64 address (as well as some other, easier functions). It's not the most elegant solution, I'm sure, but I'm proud of what I created.

Reverse ip domain look up and reverse ip lookup are two different things or same ??
Can anyone explain both if they are different 🤔5 -
so I got the reverse proxy all set up on my server, forwarding all the right headers to enable SSL behind reverse proxy. awesome! my only problem remaining is, since nginx only handles HTTP/S traffic, I can't connect to my gitlab instance via ssh. anyone know how I can proxy this traffic as well to enable ssh connection for git?3
