What it's like to be a network engineer...translated into normal people speak
User: I think we are having a major road issue.
Me: What? No, I just checked, the roads are fine. I was actually just on the roads.
User: No, I’m pretty sure the roads are down because I’m not getting pizzas.
Me: Everything else on the roads is fine. What do you mean you aren’t getting pizzas?
User: I used to get pizzas when I ordered them, now I’m not getting them. It has to be a road issue.
Me: As I said, the roads are fine. Where are you getting pizzas from?
User: I’m not really sure. Can you check all places that deliver pizzas?
Me: No I don’t even know all the places that deliver pizza. You need to narrow it down.
User: I think it is Subway.
Me: Okay, I’ll check…No, I just looked and Subway doesn't deliver pizzas.
User: I’m pretty sure it is Subway. Can you just allow all food from Subway and we can see if pizza shows up?
Me: Sigh, fine I’ve allowed all food from Subway, but I don’t think that is the issue.
User: Yeah I’m still not getting pizza. Can you check the roads?
Me: It’s not the roads, the roads are fine. I’m pretty sure Subway isn’t the place.
User: Okay, I found it. It’s Papa Johns.
Me: Okay, I looked and Papa Johns does deliver pizza. Is it the local Papa Johns or one in a different town?
User: I don’t know. Can you allow pizza from all Papa Johns to me?
Me: No I can’t do that. Can you get me an address for Papa Johns?
User: No, I only know it as Papa Johns. Can you get me all the addresses of all Papa Johns and I’ll tell you if one of them is correct?
Me: No, I don’t have time for that. Okay, I looked at the local one and it looks like they have sent you pizza in the past and they are currently allowed to send you pizzas. Try ordering a pizza while I watch.
User: Yeah still no pizza. I’m guessing they are getting blocked at the freeway. Can you check the freeway to make sure they can get through?
Me: No, this is a local delivery. They aren't even using the freeway.
User: Okay, well then it has to be a road issue.
Me: No, the roads are fine. Okay, I just drove from the Papa Johns to the address they have on file for you and there is nothing there.
User: Hmm, wait we did move recently.
Me: Did you give your new address to Papa Johns?
User: No, I just thought they would be able to look me up by name.
Me: No they need your new address. What’s your new address?
User: I’m not really sure. Can you look it up?
Me: Sigh, give me a second…Okay, I found your address and gave it to Papa Johns. Try ordering a pizza now.
User: HEY! PIZZA JUST SHOWED UP!
Me: Okay, good.
User: (To everyone else they know) I apologize for the delay in the pizza but there was a major road issue that was preventing the pizza from getting to me. The network engineer has fixed the roads and we are able to get pizza again.
Me: But it wasn’t the roads…whatever.
User: Oh, can you also check on an issue where Chinese food isn’t getting to me? I think it may be a road issue40 -
My Neural Network can recognise handwritten digits!!!
It's my second try at NN so it's faaaar from perfect (or maybe even good), but hey, it's something and only with High schools, I'm pretty satisfied with the results. If you've not seen my previous post, I'm just trying to learn NNs in C and am doing just really basic things.
Still I'm proud of my progress!
Now I'm looking forward learning some library (OpenNN + OpenCV seems cool) and trying more advanced stuff, wish me luck 😆

User Ip Address is too long (maximum is 30 characters).
Okay, dear third-party API, I guess users with IPv6 don't deserve the service... And wtf is 30-char limit for an IP address, when IPv4 can be only 15 characters long, and IPv6 can be up to 39 characters? Did you calculate a weighted average of IP length to get that number?11 -
The network starts slowing down, transactions start to fail across the 450+ stores, the website starts to spit 500 errors what is going on?
Queue a frantic running around the office working out what was going wrong... Calls from all 3 data centres, nothing is going in or out of the network.
Notice the network admin come back to his desk, his eyebrows raise and he looks left and right before unplugging his laptop ethernet from one of the server access points
The network rushes back to life, everything is fine.
That particular network mapping tool is now banned for use on production.9 -

So, continuing the story, in reverse order, on the warship and its domain setup...
One day, the CO told me that we needed to set up a proper "network". Until now, the "network" was just an old Telcom switch, and an online HDD. No DHCP, no nothing. The computers dropped to the default 169.254.0.0/16 link local block of addresses, the HDD was open to all, cute stuff. I do some research and present to him a few options. To start things off, and to show them that a proper setup is better and more functional, I set up a linux server on one old PC.
The CO is reluctant to approve of the money needed (as I have written before, budget constraints in the military is the stuff of nightmares, people there expect proper setups with two toothpicks and a rubber band). So, I employ the very principles I learned from the holy book Bastard Operator From Hell: terrorizing with intimidating-looking things. I show him the linux server, green letters over black font, ngrep -x running (it spooks many people to be shown that). After some techno-babble I got approval for a proper rack server and new PCs. Then came the hard part: convincing him to ditch the old Telcom switch in favour of a new CISCO Catalyst one.
Three hours of non-stop barrage. Long papers of NATO specifications on security standards. Subliminal threats on security compromises. God, I never knew I would have to stoop so low. How little did I know that after that...
Came the horrors of user support.
Moral of the story: an old greek saying says "even a saint needs terrorizing". Keep that in mind.4 -

The stupid stories of how I was able to break my schools network just to get better internet, as well as more ridiculous fun. XD
1st year:
It was my freshman year in college. The internet sucked really, really, really badly! Too many people were clearly using it. I had to find another way to remedy this. Upon some further research through Google I found out that one can in fact turn their computer into a router. Now what’s interesting about this network is that it only works with computers by downloading the necessary software that this network provides for you. Some weird software that actually looks through your computer and makes sure it’s ok to be added to the network. Unfortunately, routers can’t download and install that software, thus no internet… but a PC that can be changed into a router itself is a different story. I found that I can download the software check the PC and then turn on my Router feature. Viola, personal fast internet connected directly into the wall. No more sharing a single shitty router!
2nd year:
This was about the year when bitcoin mining was becoming a thing, and everyone was in on it. My shitty computer couldn’t possibly pull off mining for bitcoins. I needed something faster. How I found out that I could use my schools servers was merely an accident.
I had been installing the software on every possible PC I owned, but alas all my PC’s were just not fast enough. I decided to try it on the RDS server. It worked; the command window was pumping out coins! What I came to find out was that the RDS server had 36 cores. This thing was a beast! And it made sense that it could actually pull off mining for bitcoins. A couple nights later I signed in remotely to the RDS server. I created a macro that would continuously move my mouse around in the Remote desktop screen to keep my session alive at all times, and then I’d start my bitcoin mining operation. The following morning I wake up and my session was gone. How sad I thought. I quickly try to remote back in to see what I had collected. “Error, could not connect”. Weird… this usually never happens, maybe I did the remoting wrong. I went to my schools website to do some research on my remoting problem. It was down. In fact, everything was down… I come to find out that I had accidentally shut down the schools network because of my mining operation. I wasn’t found out, but I haven’t done any mining since then.
3rd year:
As an engineering student I found out that all engineering students get access to the school’s VPN. Cool, it is technically used to get around some wonky issues with remoting into the RDS servers. What I come to find out, after messing around with it frequently, is that I can actually use the VPN against the screwed up security on the network. Remember, how I told you that a program has to be downloaded and then one can be accepted into the network? Well, I was able to bypass all of that, simply by using the school’s VPN against itself… How dense does one have to be to not have patched that one?
4th year:
It was another programming day, and I needed access to my phones memory. Using some specially made apps I could easily connect to my phone from my computer and continue my work. But what I found out was that I could in fact travel around in the network. I discovered that I can, in fact, access my phone through the network from anywhere. What resulted was the discovery that the network scales the entirety of the school. I discovered that if I left my phone down in the engineering building and then went north to the biology building, I could still continue to access it. This seems like a very fatal flaw. My idea is to hook up a webcam to a robot and remotely controlling it from the RDS servers and having this little robot go to my classes for me.
What crazy shit have you done at your University?9 -
me: do you know what is so great about UDP jokes?
you: No
me: the fact that i don't care if you got them.1 -
I JUST FINISHED MY FIRST NEURAL NETWORK!!!
But first of all, as I know you guys, it's spaghetti code and even I as a newb see places where I used too few-dimensional array or passed useless parameters or simply wrote too many redundant lines of code. I know it. I will make it MUCH better next time. Period.
But OMFG this made me scream from happiness today!! Just these few seemingly random numbers... I'm really done.. That's why I jumped into coding year or two ago..
And for some background, I didn't study any IT school, I'm just highschooler (general grammar school) who traded gaming for learning. Also my maths teacher teached NNs on university and is very keen to teach me, so that's that.
Now I wanna make the best out of it and I'm looking forward to write some well documented and flexible library, parallelized and everything (I'm gonna learn a lot in the process of doing this) better then FANN.
Maybe I'm gonna fail(99% probability but hey, I'm programmer beginner, I still think I can code everything I want). But if there is just one moment like when I saw this screen today, I'mma trade my life for it.
Sorry for taking your time guys, I was just genuinely stunned... A lot

Lord forgive me for laughing too hard at this person/situation... I kid you NOT!
So today while everything was going well, we suddenly had network issues at work. We worked to get everything back up online asap and then sent out an email for those affected to either restart their machines or refresh their desktops but we recommend restarting... After some few client calls, this special call came in..
Riiing, riiiiiing, ring....
Me: hi, how can help you?
Client: *laughing.. This is probably a stupid question but I forgot how to "refresh" my desk top..the thing is, I have Febreeze but I don't think that's for desk tops.
Me: Wait, what? 🤔 Febreeze for what?😕
Client: You guys sent an email to refresh our desk tops and I said I have Febreeze so how will that get my things in the computer back to show again?
Me: Ohhh, no no. We meant your computer desktop. You don't need Febreeze. Right click anywhere on your computer in the screen and select refresh from the pop up menu. We meant your computer "desktop" not your actual "desk top".
Client: *starts laughing...I told you it was a stupid question
Me: don't worry.. It wasn't stupid.
After I hang up, some of my team members asked me why someone is asking about Febreeze...I told them and they all started laughing hysterically
I was still trying to digest the conversation I had just have on the phone. 😂😂😂12 -
--- UK Mobile carrier O2's data network vanishes like a fart in the wind ---
One of the largest mobile carriers in the UK; O2 has been having all manner of weird and wonderful problems this morning as bleary eyed susbcribers awoke to find their data services unavailable. What makes this particular outage interesting (more so than the annoyingly frequent wobblers some mobile masts have) is that the majority of the UK seems to be affected.
To further compound the hilarity/disaster (depending on which side of the fence you're on), Many smaller independent carriers such as GiffGaff and Tesco Mobile piggy-back off O2's network, meaning they're up the stinky creek without a paddle as well. Formal advice from the gaseous carrier is to reboot your device frequently to force a reconnect attempt, Which we're absolutely sure won't cause any issues at all with millions of devices screaming at the same network when it comes back up.
Issue reports began flooding DownDetector at around 5am (GMT), With PR minions formally acknowledging the issue 2 hours later at 7am (GMT) via the most official channel available - Twitter. After a few recent updates via the grapevine (companies involved seems to be keeping their heads down at the minute) Ericsson has been fingered for pushing out a wonky software update but there's been no official confirmation of this, so pitchforks away please folks.
If you're in need of a giggle while you wait for your 4G goodness to return, You can always hop on an open WiFi network and read the tales of distress the data-less masses are screaming into the void.4 -
The link between one of the server units and our router has been disconnected and the sales dept. has gone completely offline,

This happened sometime back..
A guy came to our university with a social network that he created. It was for students and professors to interact, to form study groups and earn points as they mark done topic as "studied". He made a deal with our university, so everyone was forced to sign up for this.
While he was giving a demo of the website, me and my friend started ranting.
"This website is shit. Why are we forced to use this?"
"This UI looks just like LinkedIn"
"This top bar is right out of bootstrap"
"I have seen that graph in one of the libraries. He didn't even change the defaults."
Another friend who was sitting besides us was hearing all this.
"I don't understand a word you guys are talking. It is too high level for me"
We replied, "Don't worry. We will talk in low level. 00101110010101..."4 -

It pisses me off that germany has no proper mobile reception fucking anywhere near rural areas.
And don't get me started on railway lines.

Boss calls: "Can you give me more bandwith?"
Me: "I can, but the other coworkers will have issues"
Boss: "Doesn't matter, and please, lift up the proxy too"
Me: "I am sorry, but I can't, that could compromise our security"
Boss: "I am giving you an order..."
Me: "Ok then..."
Me: *proceeds to give boss more bandwith and lifts up proxy (all is lost now)*
I go to see what is the boss doing with the bandwith...he was downloading League of Legends in his personal notebook...
TL;DR: Boss asks to put company at risk for the sake of a game...2 -
I just launched a small web service/app. I know this looks like a promo thing, but it's completely non-profit, open source and I'm only in it for the experience. So...
Introducing: https://gol.li
All this little app offers is a personal micro site that lists all your social network profiles. Basically share one link for all your different profiles. And yes, it includes DevRant of course. :)
There's also an iframe template for easy integration into other web apps and for the devs there's a super simple REST GET endpoint for inclusion of the data in your own apps.
The whole thing is on GitHub and I'd be more than happy for any kind of contribution. I'm looking forward to adding features like more personalization, optimizing stuff and fixing things. Also any suggestions on services you'd like see. Pretty much anything that involves a public profile goes.
I know this isn't exactly world changing, but it's just a thing I wanted to do for some time now, getting my own little app out there.9 -
"PLEASE COME QUICKLY OUR INTERNAL NETWORK IS FUCKED!
-Uh, mam', could you describe the problem?"
Spent an hour, trying to fix this "network issue". Basic level 1 and 2 support. Can't connect using RDP on the server. No teamviewer either. Unplug, replug everything. Restart the server, the router, the switches. I knew that it was something dumb. I spent 3h on the highway.
To find.
That the fucking.
Ethernet cable.
Was plugged oN THE MOTHER FUCKING ILO PORT! FUCK HP, FUCK THIS, FUCK ME BECAUSE I SHOULD'VE ASKED FOR A PHOTO.
"It's fixed, mam'. Did you touch something when it was working?
-Uh, no, I swear. Also, could you please take a look at our printer? It's not working. It was out of ink so I changed the cartridge yesterday, but today it's not working!"
The cartridge was not inserted correctly.
Then she nicely made me a coffee, thanking me for the fix and asking what the problems were.
Just kidding.4 -

HACKING 90004 -
!dev
The school I went to didn't have PCs when I first joined (had some RISC OS machines instead). They got Windows 95 PCs eventually and networked them. I had no experience with networking before this, but had a PC at home. We all had mapped drives to resources on the server. The PCs were pretty locked down - no "Run" command etc.
Anyway, one day the head of IT came in to one of the lessons and asked me "how I did it".
What had I done? Well, clearly he had seen something I'd taught one of my friends. I wrote it down for him.
1. Right-click the desktop
2. New shortcut
3. \\nameofserver
4. OK
Such hax, being able to see the file shares on the server.
Shortly after this, all computer areas had signs saying "no shortcuts allowed"... -
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.
Pictured:

Managed to make myself look like a fucking moron again today...
Can't mount NFS share, get "permission denied". Huh, that's weird... It's correctly exported.
Well it's correctly exported and rpcinfo -p $HOST times out... Must be firewall rule.
Firewall rule is changed but still no joy "permission denied"... Fuck sake networks, can't you do anything right first time?!!!
Firewall rule is correct I am reliably informed... Go about proving that it's not fucking correct and provide "evidence" to show this, I was a little bit more blunt than was strictly required.
Networks say they will take another look.
I turn NFS logging to verbose for my own interest and notice the line "path/to/directory is not a valid directory".
I, as a moron, had missed a "/" at the start of the path. That's why I still couldn't mount after the firewall change.
Go over and apologise in person and explain how I'm a total idiot. -
Well, I just learned how much of a pain it is to learn the math for learning neural networks. I really should have paid more attention in high school.
I will learn, the hard way I guess...6 -
Right, I've been here before.
Our app requires an internet connection, and one of our clients wants to roll it out on a strictly managed network.
We told them which addresses our app communicates with and their network team opened them up for traffic. Should work, right?
Nope, doesn't work.
So I request them to use Fiddler to do some debugging of the network traffic, and lo and behold, it does work when Fiddler is active.
One important detail is that Fiddler uses it's own SSL certificate to debug HTTPS communications. I've had moments where expired certificates were the cause of things not working and running Fiddler "fixes" this because of their own certificate.
So I point this out in numerous mails to their network team, every time I get a response saying "nah, that can't be it".
I keep insisting "I have had this before, please check if any installed Root CA Certificates is expired"
At this point I'm certain they have updates turned off on these machines, and their certificates must not have been updated for a long time.
At one point they come back to me. "Hey, when Fiddler is off, WireShark shows the app communicating with ICMP calls, but when it's on it shows HTTP calls instead".
...YOU'RE THE SUPPOSED NETWORK EXPERTS?! You think data can be send via ICMP? Do you even know what ICMP is? Of course you'll see ICMP calls when the network is rejecting the packages instead of HTTP calls when everything's fine.
(ICMP is used to communicate errors)
I'm trying to keep my patience with these guys until they find exactly what's wrong because even I am somewhat grasping at straws right now. But things like this makes me doubt their expertise...8 -
After moving, I don't have DSL yet so I have to use mobile data to get internet access. Additionally I had to finish a freelancing job. In Germany you have one of the most expensive and least reliable mobile networks in europe.
I had to upload my develpoed software to a remote server
So I suddenly was sent back in time. A single call would have disrupted the download (I can't use internet and phone at the same time, might be a phone issue). While my phone has "high speed" volume left and showed at least HSPA, but I still, the upload rate was prehistoric:
9 -
Oh look. The monitoring channel is in flames, smartphone is vibrating so hard it's having a seizure.
Hm. Nah it's fine. Not my...
Damn it. Incoming call. -.-
I'm actually on vacation (more like you need to trim down overtime before management get's angry).
They decided to test the new hardware / os stack I set up in the last weeks. I'd actually be happy about it If I wasn't on vacation and would be part in something that I invested a lot of time...
Well now I am. Guess what. It's running too good.
And that's not a joke. It's partly due to an upgrade in infrastructure (got rid of some last remaining 1 Gbps networks)… but also because I changed quite a lot on the OS / VM side plus we changed from XEN to Proxmox... With major tweaks, too.
The whole stack can now handle peak traffic where it would choke before, and even go beyond the old peak traffic.
Enough of introduction, the simple reason why shit burned down was because they tried out the current development branch and let it ran.
The development branch had an currently unfinished ratelimiter framework, since I didn't had time for an full burn in and didn't knew what the maxima / limits were. And since I hadn't finished that, I didn't finish the traffic shaping either.
Hm. Guess it's not good when you let a bunch of heavy parallelized data generators / analyzers run for free....
In the end, we simply shotgunned the docker development machines, because thanks to network congestion / retransmissions and feedback, they were not really cooperative via network / REST.
But hey: To infinity and beyond. XD2 -
A nice side effect of running a neural network on my home server is that I no longer need a white noise machine1
-
How can people use git like that ?
Paris' metro has a simpler network.
If you can stop yourself from all working on the same branch at least do `pull --rebase`.

So I just finished a prototyp for my thesis. Still need to segment the real data myself and collect some statistics stuff to write about the network, but I am pretty proud of the result considering the dataset is very small.
For now I need some god damn sleep.

My shitty neural network doesn't want to learn.

Hello everyone,
I'm new here. [OK. Let's skip this]
I want to know where to begin on my journey on learning how to create a program that predicts what a user will say next by storing already said things and by making specific characteristics for the users.
I know that I will need to train it with some data first lol.
But how will it do the prediction. I just need this part of understanding.
I'm sorry for my bad English btw.7 -

Building my own router was a great idea. It solved almost all of my problems.
Almost.
Just recently have I started to build a GL CI pipeline for my project. >100 jobs for each commit - quite a bundle. Naturally, I have used up all my free runners' time after a few commits, so I had to build myself a runner. "My old i7 should do well" - I thought to myself and deployed the GL runner on my local k8s cluster.
And my router is my k8s master.
And this is the ping to my router (via wifi) every time after I push to GL :)
DAMN IT!
P.S. at least I have Noctua all over that PC - I can't hear a sound out of it while all the CPUs are at 100%

So today's the day.
We've now successfully installed four Ubiquity AP's with a Ubiquity Security Gateway onto a 1000/1000 fiber line. Feels really nice when you're finished with the cable laying and everything just works™. Just getting the fiber in there was a project of its own, but now it's all complete. Tommorow I'll be working from home, and on Monday I guess I'll be bombarded with connectivity issues. Oh well, let's enjoy the weekend first 😁2 -
Microsoft servers just right now were the first servers giving me the full speed my connection can bear.

Fuck! My brain just had a catastrophic forgetting!!
I can't remember the PIN of my Android phone that I'm using right now. Luckily, I'm still in because of my finger print but won't help is phone restarts.
Seems like your can't reset PIN without entering previous PIN.

Customer complains that the deployed desktop app is slow at site x.
I check it out with users at site x, and indeed, it does have a delay when trying to connect to a share on a server.
Checks with users at site y and z, no issues.
After a bit of digging, the resolve of a DNS record is most likely the culprit.
Send the ticket to the customer network team to investigate.
Get it back after an hour.
"We have pinged the DNS name, and it responds fine, there must be a bug in the application".

Context: I (among other things) manage some servers for my students' club so I have first-hand information about anything network or server-related that happens. We basically run a big enterprise network and we allow devices to connect if a person has paid their membership and the device's MAC address (be it wireless or ethernet) is recognized by our switches/aruba controllers.
Story: So today a first complaint about "the wifi not working" came in because of Android 10 and its MAC randomization. We deal with MAC randomization on Windows laptops and PCs but I think it is disabled by default so we almost never get this type of complaint.
It took one of the other guys probably 5 minutes to figure out how to disable it... only to discover it is a per-network setting.
The actual question: If there are any network administrators here on devRant - how do you deal with this MAC filtering vs MAC randomization issue?7 -
First message of today :
"Hi, I'm X from the Y office. Do you remember that was you to set up our internal network two months ago? Ok, yesterday we called the elettrician to fix two wall plugs. Now our network is completely broken. Come to fix because we think you did something wrong."
I forced myself into some other jobs i had to do for about 2 hours. After that i grab the smartphone to answer.
Oh look, there is another message.
"Hi, always X from the Y office. We just restored the static IPs you setup after we've changed them early this morning. Now everything works again."

Took dad's phone in hand to find out a contact number and realised that his phone has become quite slow to respond.
Asked him why is that and he didn't answer my question and said that he has got a message that Airtel is giving away free 4G Sims.
Bewildered, I asked him so what is that supposed to do with his phone being slow and he said, "If we take the 4G sim, then won't that make my phone faster? I have heard that 4G is fastest network".
And my reaction was like

Which is the most promising sector of Artificial Intelligence in future(2025) ?
I am currently studying about 'Machine learning'.16 -
I'm reinventing the wheel by making yet another neural network library. It's not any good yet but I learn as I go along.
The only documentation that exists now is the admittedly quite comprehensive code comments. I'm it because Keras (using TensorFlow) requires a 3.5 compute ability rating for CUDA acceleration (which I don't have) and it doesn't support OpenCL. Eventually, I will make my implementation support both with varying levels of acceleration for different compute capabilities with the oldest supported being my hardware. If I ever get around to it.
I'd say wish me luck but determination would be infinitely more useful.2 -

Kubernetes is a breeze they said. Now I‘m sitting here for several hours trying to find out why my pods randomly fail to resolve domain names.
Coming along my adventure: broken systemd configs, systemd-resolved stub causing loops, broken k3s modules and finding out that busybox‘s nslookup is broken for versions greater than v1.28.4.
50 issues later, I figured out that the dude who setup the corporate network (where the machine in question is located) uses two nameservers: one to resolve the internal routes and one for all the external domains. Luckily, coredns randomly picks a nameserver for each request. Therefore, sometimes queries for external domains reach the nameserver dedicated to the internal network which then answers with NXDOMAIN.
I hate networking so so much...5 -
New twist on an old favorite.
Background:
- TeamA provides a service internal to the company.
- That service is made accessible to a cloud environment, also has a requirement to be made available to machines on the local network so you can develop against it.
- Company is too cheap/stupid to get a s2s vpn to their cloud provider.
- Company also only hosts production in the cloud, so all other dev is done locally, or on production non-similar infra, local dev is podman.
- They accomplish service connectivity by use of an inordinately complicated edge gateway/router/firewall/message translator/ouija board/julienne fry maker, also controlled by said service team.
Scenario:
Me: "Hey, we're cool with signing requests using an x509 cert. That said, doing so requires different code than connecting to an unsecured endpoint. Please make this service accessible to developer machines and lower environments on the internal network so we can, you know, develop."
TeamA: "The service should be accessible to [cloud ip range]"
Me: "Yes, that's a production range. We need to be able to test the signing code without testing in production"
TeamA: "Can you mock the data?"
Me: "The code we are testing is relating to auth, not business logic"
TeamA: "What are you trying to do?"
Me: "We are trying to test the code that uses the x509 you provide to connect to the service"
TeamA: "Can you deploy to the cloud"
Me: "Again, no, the cloud is only production per policy, all lower environments are in the local data center"
TeamA: "can you try connecting to the gateway?"
Me: "Yes, we have, it's not accessible, it only has public DNS, and only allows [cloud ip range]"
TeamA: "it work when we try it"
Me: "Can you please supply repro steps so we can adjust our process"
TeamA: "Yes, log into the gateway and try issuing the call from there"
Me: (╯°□°)╯︵ ┻━┻

F**king hate Windows for its insanely confusing proxy setup required for software development...
> Setup proxy in Windows network settings
> Then, setup HTTP_PROXY & HTTPS_PROXY environment variable at the system/user level.
> Followed by separate proxy settings for java, maven, docker, git, npm, bower, jspm, eclipse, VS Code, every damn IDE/Editor which downloads plugins...
> On top of everything, find out the domains which does not need to go through proxy and add them to NO_PROXY.. at each level..
> It does not end here. Sometimes, I need to setup proxy for SSH connections... like, if I have to use git with SSH and not HTTP/S... Uhhh....
More than half of the problems me and my dev team face is related to setting the right proxy. Why can't it be like, set in one place and everything picks up from there, like in any linux machine or for God's sake, a Mac ?
Worst of all is, my org uses a configuration script, which resolves into a list of proxy servers, from which one of them will be used. So, I need to download that script, find out which is the right proxy server and then, use it in all the aforesaid places... WTH ?????
Is this a common workplace problem for all developers ??? Will this be solved by Windows Subsystem for Linux ???9 -
The most crazy issue I've fixed was caused by a TCP behavior which I didn't know, called the "half-closed connection".
There was a third-party application installed on a production server which called a LDAP server for retrieving users information. During the day we had several users using the application and all worked fine. During the night, when the application was not accessed, something happened and the first call to the application in the morning was stuck for about 5 minutes before returning a response. I tried to reproduce the issue in a testing environment without success. Then I discovered that the application and the LDAP server were located on two different networks, with a firewall between them. And firewalls sometimes drop old connections. For this reason network applications usually implement a keep-alive mechanism. Well, the default LDAP Java libraries don't set the keep-alive on their connections. So, I found a library called "libdontdie", which force the keep-alive on the connections. I installed the library on the server, loaded it at the startup and the weird stuck behavior in the morning disappeared.2 -
So I was setting up ELK (Elasticsearch, Logstash and Kibana) all in one EC2 on AWS today for demo purposes. I had everything prepared. Elastic IP, correct security group rules, etc.
I figured I would just do quick test before writing filters and templates if I can access Kibana. So I started service for it and tried to open it with Chrome.
Timeout.
Checked config file. Compared it to documentation. Seemed good but changed some things just for sake of change. Restarted service.
Timeout.
Reverted changes I've made in config. Restarted service. Curl on localhost. It work... OK. 😐
It took me half an hour but finally I figured it out after I took my phone and opened it from there. It was working from the beginning. Stupid company network was for some reason blocking this connection. Fuck! 😡And I was restarting that poor service like crazy trying to fix something that wasn't broken. -

Someone wanted to take a look to kde on Ubuntu 18.04 in my laptop, so did:
`sudo tasksel install kubuntu-desktop`
After rebooting and all did:
`sudo tasksell remove kubuntu-desktop`
and now I don't have GUI. The problem is that I can't also have network, neither by WiFi or ethernet. So I can't install packages.
The best way to fix that is to reinstall Ubuntu? Or there is a way to recover the ability to connect to network?

So today I was messing with a side project and for context it’s a networking program.
So I’ve designed the programs packets and what each do. The final step is just constructing them and sending them, but wait some random error that I traced from the file path being wrong to the packet containing a files name but then I realized that the packet after the file name wasn’t sending and so I looked at the contents of the first packet and IT WAS SENDING BOTH CONTENTS IN ONE and I fucking can’t tell you how hung up on this I got because there was nothing wrong with any other packet in anyway, and if I commented the file name packet out the next one worked and vice versa and it was so fucking infuriating and out of desperation I thought “what if I just gave it time between sending both” AND IT FUCKING WORKED. ONE LITTLE FUCKING sleep(.5) FIXES THE PROBLEM THAT PLAGUED ME QUITE LITERALLY ALL DAY I CANT. IM PRETTY SURE ITS STILL NOT A GOOD SOLUTION BUT IM ROLLING WITH IT!1 -

Here some more information to despise Apple.
In the past few weeks I keep having a problem making the iMac connect to whatever website/host, so I had to rerun whatever I had to do: fetching from github, push to github, connecting to a LAN server, pinging to know to IP, accessing a webpage and so on.
Luckily enough, browsers tend to request again if an error occurs.
At my job, I upload app files to servers, like GooglePlay and AppStoreConnect.
For those who don't know, Google makes you upload the app through the browser (among other ways) while Apple requires you to upload your app either through XCode. No other possible ways.
Whenever XCode requires an update, the authentication is required, but the authentication server cannot be reached for at least 5-6 tries.
Then I have to upload the app and just to be ready to hit the "upload button" it takes like 3-4 minutes, which might be completely useless if a network error occurs.
How hard is it to make your fucking app-loader to try again at least a few times?7 -

Hey Dominique, are you sure the password you used is correct? Is it yours or the sysuser pw what you sent to the server? How did you send it?
Me: (kind of confused) Hey dear admin, did you look at my error message? It says Hostname not found. What do you think how I provided any credentials?
Support: yes, I saw your screenshot and don't see any password entry. That's why I asked!
Me: Well, than... ok... go and search for another job. Yeah and consider fucking yourself. Kisses. -

Same with other files, on computer can be mounted as network drive.
Or small app with drag drop or cli to add / remove shared directories.
Can be raspberry pi device.
Thinking more, it should work like vpn network but with tunnels between computers.

I currently use Github as my git server and have worked a little bit with Travis. Sadly Travis can't deploy to local network targets and that's why I had the idea to create my own basic CI for the local network: It will be a simple nodejs-app and listens to pushes via Github Webhooks. Then it fetches the code from Github and runs a task runner like Gulp over it and tests it with any nodejs testing framework. Then it deploys the compiled, tested and linted app to the local network. What do you think of this idea?8

I've been googling for hours and nothing I try seems to work, any Linux pros here able to give me some suggestions. The network card in the PC is an Aetheros one, I it supports a,b,g,n and Bluetooth, I'm currently using the desktop with a Bluetooth mouse / kbd.

Customer: You don't seem very comfortable with this; maybe you could pass it on to another engineer..?
Situation:
I'm a System Management team engineer. Customer is asking about licensing (which is a different team) and has that very rude habit of asking a question, doing a small pause in which I start answering, and then speaking again and cutting me off; thus causing me to seem very splutter-y. Since I couldn't give a definitive answer to his licensing question he doubts everything and thinks I can't do crap. And he's the one who wants me to sit on an upgrade with him because he's too afraid to follow documentation.
His words to me: "Have you ever done this upgrade before; I mean are you familiar with it?"
Me: "Nope since it's not policy to sit on upgrades as we are a break-fix center but I've directed other customers to do it through the documentation I've given you and they got on fine."
Seriously doubt the capacity of some of these guys to do an upgrade where there's step-by-step videos and very legit documentation (never mind this upgrade uses the tool which has the best record for not breaking)4 -
What would it take to connect two Raspberry Pi's together via Ethernet ports? I want to make a low latency network connection between them, for Retropie Netplay.

Does any one of you own a Omnia Turris (https://omnia.turris.cz/en/)?
In our new apartment, we'll have a 1 Gbps fibre connection (not that we would realy need it, but hey!)

Ever since I started learning about React with Typescript my respect for design patterns that restrict how state can change has grown massively.

Not a rant more like a question
Hello devRant,
I am currently planning to purchase a small home server + media client (with Kodi).
A small Linux Distro running the Hometheateroftware Kodi will run on the media clients (Odroid C2). The control is then over an app over the local network. The database of Kodi should be on the server in the form of a MySQL database. The movies, pictures, music are also streamed by the server (max. 2 simultaneously) via SMB (simplest variant). In addition, the server is to be accessible to the outside via a web interface to act as a cloud (maybe nextcloud). The whole should be optimized for stability and longevity. In addition, a small GitLab CE instance will probably run on the server. Do you have any comments or objections? The fact that I only take 2x ne 2 TB hard drive has the simple reason that I currently have no need for more space. Sometimes it happens to me that I forget completely obvious things :D -
So I just got a Watchguard Firebox x500 for free. What should I do with it? And how do I set it up? (For a home network).4

Hi fellow DevRanters! I've been studying software engineering for a while now and, while I love programming, I'm starting to think that all I'll be doing as a software engineer now a days is pulling data from a database, sticking it in a nice gui with some buttons and moving on to the next, similar, project. At the same time I am loving linux more and more, I love working with bash and other unix-like tools and I am interested in systems languages like C and Rust. It is for these reasons that I am playing with the idea of switching to Systems and network engineering. What are your thoughts on this? Is Systems and network engineering a field in which I get to program a lot? Will there be more variation in it? Is my view of software engineering completely off? Please share your thoughts and opinions! -

So, something changed at our company not allowing me to connect with the correct network. Now this is barely a problem since I can still connect with another network, however the only thing I can't do now is push and pull from git... Every time I have to sync, I have to set up the hotspot on my phone. Apparantly, that's more often than I thought. Also, in order to work on the application I have to be connected to the company network because our application uses windows authentication, so I keep switching back and forth.1

!rant => question?
I'm hired as a freelancer for a start-up that wants to create a social-network-like platform. I've always been a "basic" PHP and javascript developer like using AngularJS, MySQL and my own kinda like PHP MVC framework etc.. But I'm worried that 'this' will come short when the platform expands on the user-base and stuff. That MySQL won't be able to keep up with the expectations and the amountof data, that AngularJS will not be enough for the Frontend,.. I've taken a look at ReactJS, RethinkDB, NodeJS and such, but this is not really within my "comfort zone" and I'm not willing to invest time in something new if it's not able to handle the platform (I don't know if it will..) and I'm afraid that I'll have to start from scratch if it all fails.. (and this is something I can't afford)
So.. What are you guys's opinions? We're not looking at millions of users, but it will have feeds, comments, connections, messages, post scopes,.. Etc. RethinkDB looks promising with the 'watchers' to get live data instantly, but it's a whole new way of query'ing and such.. It just feels like I'm wasting my time because I'm afraid that I'll reach a point in development where I'll have a situation for example like "damn.. This is impossible with angular or php.." [I've shouldn't have agreed to this project..] :D1 -
I can't post a collab from the web client and I don't have a decent phone atm, anyways, this is an idea, tell me if you have any improvements or if you know of an implementation or would be interested in creating one.
A social network comment system that connects people across fields of interest and aids keeping relevant posts alive for a long time.
The basic principle is this: Every post may identify itself as a child to any number of other posts, or sections in other posts, which then act much like a bidirectional hyperlink between parent and child.
This leads to two unusual results:
1. that comments aren’t only added to posts, but specific paragraphs, sentences or even words.
2. that any comment may receive comments in much the same way the original post did, making comments identical to posts. (they could have their own pages and all).
This is in many ways like Reddit's infinite comment chains. The main difference is that here comments aren’t organized in trees but graphs, which makes it possible to connect related conversations from entirely different groups and times, resulting in a much more open yet concise discourse style with an increased persistence of topics. -
Network Support is the worst place to work in especially when you done all your work in the first hour. Also, when managers are pain in the ass.
Might as well call it a call centre rather than Service Desk -
I was ten years old. At this point, despite being in my early 20's, I've officially been programming more than half of my life. From the first moment I knew that this was possible, that we, as software engineers, can do what we do... I've been quite literally obsessed with the idea.
I don't like to give other people credit for the events in my own life, but there is one thing that, more than anything else at the time that lead me down the path of computer science, directly lead me to where I'm at today. If you're at all interested in film and cinema (not to mention programming) then you've undoubtedly heard of The Social Network, directed by David Fincher. Amazing film, I'd recommend it to anyone based off of the film alone, but for me that movie holds a special place in my heart.
My mom took me to see it that movie in theaters when it came out, I would not stop bugging her to take me, there was just something about the founding of Facebook that... Sparked my young imagination. I swear to you that I didn't blink for the entire time I was in the theater watching it. It blew my mind, not only that you could do that kind of stuff with computers, but that you could actually make a lot of money working with computers as well... Ten year old me had different priorities in regards to programming 😂 Starting the moment I got home from the theater, I dedicated my life to learning everything I could about computers. Originally my goal was to, shock of all shocks, create a social networking site for me and my friends to use. I still like to brag about it to this day, but that project eventually became my groups final project in our computer class in Middle School. It was funny, middle school computer class, I had already been programming a few years by that point and was rather proficient in PHP. There were kids submitting literal spreadsheets in Excel as their final project, a few static HTML pages, that sorta jazz. My group and I submitted a full fledged twitter clone, with complete functionality. We got 100% on the project 😂😂
My reasons and interests have changed over the years. For example, I'm not particularly interested in creating a social media application these days, and I don't program because I think it'll make me rich one day (though the hopes always there) but the one thing that hasn't changed since that night I sat enraptured in the beautiful cinematography of David Fincher and facepaced dialogue of Aaron Sorkin, is the complete and total fascination with computers and technology. For that reason The Social Network will forever be my favorite movie.3 -
This literally just happened: "Our network is down". No internet and backup seems to be failing as well. Thankfully I can still develop locally with git. Now to be able to focus. I'm not shitting you when I say a guy with a sandbelt machine is grinding down a door 3 metres away from me.

At my boarding school the admins are too bad : all the 5 min the internet go out for 30s because of overload (when too many computers are downloading) and now when we must work the internet go out so we can't work....
Windows says that the proxy is not responding so it's again a big overload and the internet came back the next day thank of reboot ...
This system is soooo shity.....
And my school want to have a good image of technology....... WOW ! -
I was surfing the web.....
Let's see if there is something new about comma ai
Maybe they decided to really release their source (visiond, etc...)
[Actually they don't :-( ]
So my trip begins...
comma(.)ai -> youtube -> github -> youtube (again) ->> etc...
Then i found this:
openpilotlegacy(.)org

Fucking Intel. Only allowing specific SFP transceivers on their x520-da2 card. I gotta load the firmware with a flag to be allowed to use my ubiquti transceivers.
And for some reason grub doesn’t let me use the “array” as the firmware said. So only one sfp port is active on boot. So I gotta find a clever way to get it to load properly. Maybe add a script to run at boot that does what I want. -
Four major network disruptions on east coast the past week. Today fiber cut in Florida effecting central Florida. Verizon, AT&T and Sprint have each had disruptions impacting many businesses and customers. Coincidence?

So I just received the WiFi Route for my new apartment where I will move in with my girlfriend next week. This friday I will install this thing so everything will work when we arrive next week. So now I standing in front of the most important question:
How to call my network? Any suggestions? Maybe not that hard tech/coding relating bc I really don't want to explain it to everyone visiting me.
Thanks for your ideas!5 -
I want to do ssh is from outside the network. But I'm unable to do it. Very much frustrated. Has anyone tried it successfully?7

SMB/CIFS support on Linux distros is a nightmare! Switching from wired to wireless will cause ALL mounts to freeze, and they all become impossible to dismount normally. You can't even ls the root folder anymore if there are frozen mount folders inside. It's f#&%ing retarded to have to reboot your PC twice a day because you lost WiFi signal for one second, and the underlying processes don't understand SIGTERM. And I could go on about MTP! Standard file transfer protocol for Android but boy it is hellish. Trying to copy a structure with subfolders will take forever because every ls call to the phone is like an API call to some free webhosting company in Australia, takes forever, if it even succeeds. I won't even get started on WebDAV and SSHFS (the latter is even worse than CIFS). Those make me want to do unpleasant things to my computer. So frustrating! I can't be the only one who has experienced this, right?1

Is there a cloud service that does nothing but redirect incoming HTTP requests to your home server without the need to have a static IP or an open TCP port ? Sort of like proxy2

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?

Have anyone tried to train a neural network(CNN) with cuda enabled on laptop with nvidia mx150?
How was it? And what about another one with 1050 ti? Is the difference huge?5 -
Im facing an issue with my schools network.they block almost all ports. Ssh isnt open and a lot of websites are blocked. Cant use a vpn to surpass that sadly. Tho a vpn with sstp support works. Can someone reccomend a vpn that allows sstp or can i somehow make mullvad use sstp?4

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?

If I would be a network administrator , I would troll everyone by creating 2 networks, one called x-fast and another called x-slow. Obviously I would reverse them so the one called slow is actually fast, and the fast one is slow. So I can benefit myself from a private network with no one on it because it's "slow" :-)
Evil me or genius?2 -
I've been struggling with the network I set up for my bachelor thesis for weeks. Today I figured out it was all caused by STP which disabled connections that I tried to use. Disabling STP solved all my problems.
The relieve is strong -
Google hangouts on air: if you could not drop everything you recorded so far when I lost connection with the internet for a minute once I am an hour and a half into the meeting... that would be great.1

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 -
Thank God for "Screen" my remote Linux build session is alive in spite of fucking network outages! I'm telling you, when your company doesn't have voltage regulators, network goes down everytime there's an electrical fluctuation!

Since the new update I have many issues with loading oft rants.
When I click on a rant, the devRant Logo Smiley Shows up for several seconds, than it Just disappears. And then nothing Happens.
Have to Go Back again, and Back again and sometimes also Close the App before the rant is loading again.
Is it only me?

Does anyone know of a simple facial recognition program that I could train locally on a set of people’s faces?
I’m tasked with culling through a few hundred photos to find ones of certain people. I need the originals taken off the network drive and copied to a hard-disk.1 -

Hey there. Does anybody know a good tool to visualize a computer network? I've played around with cytoscape and gephi, but it's not really what i'm looking for. I also tried http://graph.io It's ok but kind of a pain in the butt to work with.
Just to let you know: i want to show our intern next week how we are organized with our servers :)2 -
Looking to get a good understanding of the fundamental ideology and math behind neural networks and support vector machines. I am well versed with math so I can deal with heavier stuff if needed, I would like to see formulas but an explanation to their conception would be nice. Does anyone have any resources like this? Practical hands on practice exercises would be a plus2

please whats the easiest way i could train a neural network without writing a code,i have data set of about 700 images9

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 -
Todays website fail, looks like someone is using a NFS mount for the site:
"Deprecated: Non-static method PageLinesTemplate::current_admin_post_type() should not be called statically, assuming $this from incompatible context in /nfs/c03/h03/mnt/166492/domains/makerspace.com/html/wp-content/themes/pagelines/admin/class.options.metapanel.php on line 30" -
Oh your router can't find its eigrp neighbour, hmm oh look you switched 27 to 72 in your anouncement network ip. This was my mistake that cost me and my m8 1,5 hours of head scratching....

I have never heard anyone say Gee-Nome. Does anyone actually do this or is the Cisco Network Academy bullshitting me again?

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.

What's your experience with Activity Stream (v1/2)?
Is it worth the trouble building a social network system with this tech in mind? -

I have a couple of "at risk" teens (I won't say what) who need an extra level of Internet filtering and restriction for their own protection against their use of really bad judgment. I've already enabled the OpenDNS parental control URL/content filters on my Netgear R8000 router but one of the teens has figured out how to install a VPN on mobile. I want to enable the router's OpenVPN feature for better overall security for all of us. But is there a way to block the use of an "unauthorized" VPN, like on a mobile device, without also effectively blocking my router's OpenVPN as well? I was looking at this post (https://community.netgear.com/t5/...) but wondered if anyone here has experience with this.6

Has anyone here tried spacehey.com. Recently, i checked there are now 50,000 people on spacehey. If someone has tried it, i just want to know why people are registering themselves there? 🤔1
