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! 😕

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?

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 -
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?
Dave:...
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.

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!!!

Android Dev: *sent and email to network admin* can you please unblock github for a few mins.
Network admin: *Replied* Can you take a screenshot whats the error your getting.
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?
Network admin: there must be a problem with your code that needs to be tweaked.

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

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 -
Windows, God damn you piece of fucking shit.
Why the fuck can't you make networking fucking easy like literally every other fucking operating system in the goddamn fucking world?
Why the fuck can't I spoof mac addresses so that I have the same IP address regardless of if I'm on a hard line or wireless?
Who in their fucking right mind thought that the pro version of Windows wouldn't need to do that?
I don't even like using you at this point, I'm forced to use you for work.
There's literally not enough explicitives that I can chain together to sufficiently convey how much I fucking hate you Microsoft. So enjoy this seizure inducing tourette's mode compilation.
Fuck shit cock piss mother fucker asshole bitch mother fucker sick and tired of your fucking shit Microsoft you fucking cuck piece of shit nobody fucking likes you they only have to use you because no fucking business in their right mind is going to spend the millions of dollars it cost to fucking switch over to fucking Mac or Linux I hope you fucking choking a bag of HIV riddled flaming dicks you fucking piece of shit.17 -

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.3 -

Today the IT deparment update the firewall's configuration, they blocked almost every website except email and Google.
The problems:
- 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 -

The new mobile app codebase i'm working with, was clearly written by someone who just read a book on generics and encapsulation.
I need to pull out 2 screens into a separate library to have it shared around. The 1 networking request used is wrapped up in a 'WebServiceFactory' and `WebServiceObjectMapper`, used by a `NetworkingManager` which exposes a generic `request` method taking in a `TopLevelResponse` type (Which has imported every model) which uses a factory method to get the real response type.
This is needed by the `Router` which takes a generic `Action` which they've subclassed for each and every use case needing server communication.
Then the networking request function is part of a chain of 4 near identical functions spread across 4 different files, each one doing a tiny bit more than the last and casting everything to a new god damn protocol, because fuck concrete types.
Its not even used in that many places, theres like 6 networking calls. Why are people so god damn fucking stupid and insist on over engineering the shit out of their apps. I'm fed the fuck up with these useless skidmarks.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 -

If finally happened. My cats broke me down.
After years of spotty internet, in which I couldn't resolve websites, to which the solution always was to reach down and push the RJ45 jack with the broken off clip that connects my router to my pihole back in, because my cats pulled it out once again.
They made me do. They finally made me do it. After all those years. Today, my cat pulled it out like ten times in a row... So I finally did it. I walked over in the other room, grabbed a new cable and plugged that one it.
Try that again, cat. I dare you. Try it again!1 -
The amount of "full stack" developers I've seen that know nothing about networking, servers or security has broken me inside over the years. Like cmon man either learn that stuff or stick to doing frontend. Don't put user's data at risk just because you wanna earn a bit more money11

What is it with devs (not all, by any means!) who don't understand networks or basic computer operation? I'm not talking about anything complex, but things like the dev who asked if his IP address could be whitelisted so he could remote in from home. We asked what his public IP address is and he said 10.0.0.27.
Or the new dev who started and said her laptop camera didn't work and logged a ticket, only to be asked if she had the camera cover open or closed and said, "oh, that's what that lever is for."
Don't get me wrong - many devs and sysadmins and IT people of all fields are excellent. And there are some who are crap in every field. This is no rant about devs in general, just *these* crap devs that I can only throw my hands in the air and think, well, they scored ok in the SQL test.4 -

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 -

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.

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'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. -
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 -
Connecting my Pi to the interwebs through my computer should be easy, right?

I've got a kinda basic networking question I can't quite figure out
How does a push notification work?
Like, on an Android app. A good example is an authenticator. Say I don't login to the service for 4 months.
Then, one day, I try to log into the web portal and it prompts me to accept the request on my authenticator app on my phone.
Immediately, there's a push notification on my phone.
Wtf.
Is there a socket open for 4 months? Does it send requests every few seconds for 4 months? I can't imagine that either of these options scale whatsoever: both horrendously waste bandwidth and server connections.

Today, I used NAT in a way I never before thought of as a solution to a problem - Exposing a service listening only on an internal address, to the internet, to a selected list of hosts.
For some reason, it made me a little sick in my mouth. It feels... Ugly, to solve this as such. But I was only copying this solution from a different server of the same client, so no reason to implement it differently and thus complicate future administration...
Is it normal to use DNAT like this?1 -
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

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.

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 -

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 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!3 -

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 -

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

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?3 -

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 -

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.

Got a legit question/semi rant for anyone who may know. I want to start by saying that I'm not really a "network" person, at least on MS systems. I can physically plug cables in and shit like that, but the software side of networking is not a thing with which I can claim familiarity. Anyone who's read my recent rants will know that I am forced to deal with IIS, because my boss is an insufferable microshit fanboy of the highest level, and is easily frightened and threatened by the use of a keyboard for anything other than using facebook.
I've got a couple of microservices running under IIS, and our customers thankfully are able to access them with no issues. Those of us in the "IT department" are also able to access it. No one else in the building, on our network can, and despite me not having set up this network, or really having anything to do with it, the rest of my "team" (LOL) refuses to help me solve the problem, because developer = networking specialist and printer fixer. Does anyone here have an idea? I found a think on Stack Overflow about firewall rules, but those are already set appropriately.7 -
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 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.
(Or help me?)
Once again.
Asshole ISP.
Fuck your firewall.

Fuck's sake, why is setting up ipv6 for an LXC container so hard?

Been thinking about game design. Making things testable and modular. I think I have a lot to learn in this area. One idea popped up in my head. How can I design the game so that it can be networked later? One idea was an interface in the logic that gives authority to another set of code (module?). Basically include the abstraction as if networking was there. So if/when I decide the next version of the game or existing version should have online play. I think learning to create client/server would be instructional. Maybe networking could be a dlc or something.5

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)3 -

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 -

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?
