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 issue49 -

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 😆

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.10 -

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.

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: *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.

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 -

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 -
"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 -
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...6 -

Dear router
It was nice having you in my house, but it's come to the point where our ways part. I must go on and you must be recycled. You've served me well all those 7 years, my friend.
It's not me, it's you. You've grown old and unreliable. Your capacitors must have dried out and can no longer serve reliable wifi connections. I keep on getting lost ICMP packets and connection outages altogether. While these things could happen to any router, definitely not every router has a 13-16 second long wifi outage every minute. I cannot have 2 peoples' work depend on a wifi connection where a ping to a LAN IP takes 58204ms. I just.. can't. You've become a liability to my family.
I'm pissed, because I cannot afford video calls with my colleagues.
I'm pissed, because my wife spends good 5 minutes every call asking "can you hear me? how about now?" and repeating herself over and over.
I'm pissed, because I can no longer watch Netflix or listen to YT Music uninterrupted by network outages.
I'm pissed, because my Cinnamon plugins freeze my UI, waiting for network response
But most of all I'm pissed, because I was disconnected from BeatSaber multiplayer server when I scored a Full Combo in Expert "Camellia: Ghost" - right before I got a chance to see my score.
I gave you 2 second chances by factory-resetting you. I admit you got better. And then got back to terrible again.
I can no longer rely on you. It's time to say our goodbies and part our ways.
P.S. as a proof of your unreliability I'm attaching outputs of ping to a LAN IP and pingloss to the same IP (pingloss: https://gitlab.com/-/snippets/...)

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".

What if we fed all rants and comments on devRant to a neural network trained to write rants and comments on others?10
-
So I found a thing. On my laptop, I am able to create a hotspot. So someone can connect to it and I can share my internet access. Couldn't I theoretically impersonate a wifi name, by setting up the hotspot to use the SSID of the target network, then the clients that already have access to the target network would feed me the network credentials? If so, how would I go about capturing the creds?12

Always test your fucking mocks
I spent 3 weeks debugging every part of the application, except for the mock network connection. The mock network connection didn't trigger closing events on the sender side. -
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."
Oh really ?1 -

My school blocks all UDP traffic going outside their network. 1 - 65535. Which in turn means that I had to switch to TCP for my VPN to connect. Now my VPN is slow as shit. -.-8

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 -

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 -
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

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...4 -
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 -
Took the day and rebuilt my home network with no major issues along the way.
Migrated to a new NAS and gave a Raspberry Pi a new life as a PiHole + DHCP.

There will always be an idiot in a IT department that will ruin your Saturday, by adding a few more network restrictions for no freaking reason, breaking everything else.

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 -
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. -
OS can’t install the network driver because the installer can’t see the network card, the installer can’t see the network cars because the driver isn’t installed.1

A bit confused !
Must prepare an article about network pentest and defense .
Since its a very wide topic and I've been told not to just mention tools , I'm confused about categorizing these tests !
Also the footprinting stage is not likely to have any defense !(no attack is lunched yet :) )

Some <super smart> person ran DHCP in production lab (without disconnecting from main network and/or using firewall)
, now the admin turned all the ports off and went home.
Traffic gens are also unavailable now so are upgrade servers.

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?
BTW, yes: "someone" was myself.
Shame on me 😔5 -
How to know your network proxy sucks: when everything IDE-related (downloading new package, using Gradle…) is blocked, but almost everything prohibited (like streaming) isn't.

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?6 -
And this happened today:
While on ssh session, this guy restarted network manager. According to him "his Facebook page wasn't showing him recent feeds". -

We run 20.04 Ubuntu at work with fucking Gnome. I thought to myself "by now I should be able to easily make a desktop/launcher icon". Nope, fucking dark ages. What a pos window manager.
At work we have 2 networks. One is guest and one is for our work computers. I was trying to put a computer on the guest network to limit access to a vendor. I noticed when I logged in I could see all the computers on the work network. Surely this isn't so? I check on another computer on guest network. Yep I can see all the same servers and machines. Guest network has easily guessable password. How the fuck do you mess that up? We have someone doing IT work now. People were unsure if we needed dedicated IT. This is just another example of yes we fucking do need a dedicated IT person. Laughing and shaking head. It is not like we ever have foreign nationals from tentatively adversarial nations here...
I got past the barrier in Avorion on a normal play through. Was harder than in the past. I had already befriended a civilization that existed behind the barrier. So getting higher tech levels just cost about 15M credits. Avorion is getting better as a game over time. I like the economy sim and building stuff to make passive income in game.5 -
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 -

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
-
Does somebody know a js library to make a route network on a map, like the ones airlines use. Where you can enter/click on the departure and it displays a forced node graph of the destinations from a database. Like this: http://easyjet.com/ch-de/...

I just had the idea for a social network which would care about privacy, don't sell the data of its users and stuff. This would mean the users had to pay for it to keep the lights on, like 1 oder 2 bucks a month.

Anyone know private/encrypted p2p network drive app (best would be opensource) between devices in the internet, with multiple user support, invite only ?
It should work behind nat so need use some 3rd party hole punching server for handshakes.
Let’s say I got a movie I want to share with my friend but instead of him downloading it, I would stream it directly from my device and my friend would open it using ex vlc.
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.
Can it be done using ipfs ?1 -

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.
I have a background in Python and some Linux, but I'm not well versed in raspi's.
I imagine that it would be limited to 100mb/s if I used raspberry pi zeros with adapters. And I would probably need an router since they aren't setup to be both hosts with the default setup?2 -
Our ISP asked if I was satisfied with their service. I told them that it's okay, but some of our computers don't have enough powerful network card, and they can't use the internet on maximum speed, and they said that they could see it, too. WTF? I knew that the ISP's router is not the most secure thing, but it has a remote mode, which if of course OFF, and they still can see this, and maybe even more. Monitoring your traffic is a thing, but a home network should be private...2

WTF, you can create SFTP users on Linux and restrict their access and even set a home directory.
Yeah, now we need to forget about themes and plugins in WordPress.

So I just installed Elementary OS Loki on my older desktop and for that the wifi is incredibly slow, like 30 seconds to load googles home page. It also randomly stops working, and gives a no network connection. When this system was on windows I would average 50~ mb/s down speed, changing it to Linux I'm lucky to maintain 2mb/s. 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.

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

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

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 -

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! -

I'de really love to see one of the Yolo version walked through and trained but honestly any localization would be helpful.
