Who knew, Usb and rj45 are the same width? Not me after spending 10 mins trying to work out why mouse not working.

University dorm admin story:
One guy had a problem with his ethernet cable. He broke RJ45 and wanted new one, so he asked on dorms group what to do. He was pointed to admin. So he grabbed a knife, cut the cable as close to wall as he could and walked with it to the admin guy. He said that he had problem with his cable and want new RJ45, so admin applied it on the both sides. Then he asked how to plug it back to the wall :D19 -
Man : Just give me the bald overhead with RJ45 clips to keep my hair tied at the back
Barber : I got you fam

Lenovo, you dumb fuck cunts.
How the fuck did you think it might be okay to ship a laptop with a BROKEN FUCKING WLAN DRIVER??????
This piece of shit doesn't even have RJ45 anymore.
And also who shit in your empty cavities where your brains should be when you thought it was a good thing to disable booting from anything but the main windows partition? My Mint installer stick works on any and everything I have ever tried him with except for this.3 -
If finally happened. My cats broke me down.
After years of spotty internet, in which I couldn't resolve websites, to which the solution always was to reach down and push the RJ45 jack with the broken off clip that connects my router to my pihole back in, because my cats pulled it out once again.
They made me do. They finally made me do it. After all those years. Today, my cat pulled it out like ten times in a row... So I finally did it. I walked over in the other room, grabbed a new cable and plugged that one it.
Try that again, cat. I dare you. Try it again!1 -
Murphy's law:
When you try to unplug a USB from a FULL USB HUB with twisted (and same color wires)
You always will unplug the wrong usb at fist shot.
I think that this can be applied also to phone chargers,RJ45,RJ11,etc.....2 -
## Building my own router
So after poor luck with mPCIe in my miniPC I decided to go with USB wifi solutions. So I got the https://aliexpress.com/item/... , hooked it up and started setting things up. Took me a day to figure out that firewalld (CentOS7/8 firewall) is not directly compatible with raw iptables commands. Damn it! But hey, a lesson learnt is time well spent!
Installed named, dhcpd, hostapd, disabled NetworkManager for my wifi card, etc.. And had to learn another lesson -- if a netowrk interface is bridged then iptables sees the bridge rather than the raw interface. That's another 2 hours well spent :)
In the end I have a working AP!!! It's still hooked in to my router via RJ45, but it does work and does work quite well!
Here's some comparison for now:
via router (2.4): https://speedtest.net/result/...
via router (5): https://speedtest.net/result/...
via miniPC (2.4): https://speedtest.net/result/...
via miniPC (5): <TBD>
Not that bad, aye?
All in all I'm happy with my decision to build a miniPC based router. Now I have the modularity I wanted so mush and a complete control on my networking! Can't wait for wifi6 USB dongles to be released :)3 -
I already wrote a rant about this yesterday, but since I'm a sysadmin trying to convert to dev.. I dunno, maybe it's not a bad idea to muddy the waters a bit and talk about why not to be a sysadmin.
Personally I think it's that the perceived barrier to entry is just too high, while it isn't. You don't need a huge Ceph cluster and massive servers when you're just starting out. Why overbuild an appliance like that if it's gonna start out at maybe 5 requests a minute?
Let's take an example - DNS servers! So there's been this guy on the bind-users mailing list asking how to set up a DNS server on 2 public servers, along with a website. Nothing special I guess - you can read the thread here: https://0x0.st/ZY-d. Aside from the question being quite confusing, there was advice to read RFC's, get a book, read the BIND ARM, etc etc. And the person to deny this? No one less than Stephane Bortzmeyer, one of the people who works for nic.fr (so he maintains the .fr TLD) and wrote some of those RFC's as part of the DNSOP working group in the IETF. As for valid reasons to set up a DNS server? Could just be to learn how the DNS works, or hell even for fun. As far as professional DNS servers go.. this (https://0x0.st/ZYo9) is the nugget that powers the K root server, one of the 13 root servers that power the root zone of the internet, aka the zone apex. 2 RJ45 connections, and a console connection. The reason why this is possible is the massive recursor networks that ISP's, Google DNS, Cloudflare DNS, Quad9, etc etc provide. Point is, you don't need huge infrastructure to run a server!
Or maybe your business needs email. How many thousands of emails per second are you gonna need to build your mail server against? How many millions will you need to store? If your business has 10 employees and all of those manage about 10k emails total.. well that's easy, 100k emails total. Per second? Hundreds of emails per second per employee? Haha, of course not. Maybe you'll see an email a minute at most. That is not to say that all email services are like this - it is true that ISP's who offer email to their customers, and especially providers like Microsoft and Google do need massive mail servers that can handle thousands of emails per second. But you are not Microsoft or Google. So yeah, focus on the parts of email that are actually hard.. and there is plenty.
Among sysadmins you have this distinction between "professional" sysadmins and homelabbers. I don't mind the distinction itself but I think both augment each other. If you've started out by jumping into a heap of legacy at an established company, you will have plenty of resources, immediately high complexity, and probably a clusterfuck right away. But you will have massive amounts of resources. If you start out with a homelab, you will have not many resources, small workloads, and something completely new for you to build and learn with. And when running a server like that, you'll probably find that the resources required are quite small, to provide you with your new services. My DHCP servers take 12MB memory each. My DNS servers hover around the 40MB mark. The mail server.. to be fair that one consumes around 150. But if you'd hear the people saying that you need huge servers.. omg you need at least a TB of RAM on your server and 72 cores, massive disks and Ceph!1!
No you don't. All that does is scaring people away and creating a toxic environment for everyone. Stop it.1 -
today I learned that there are actually two ways how you can wire a RJ45 socket (wifi cable)
today was also a longer day than planned ...11 -
What's your view on workplace relationships or hook ups? 😄
(Sticking an RJ45 in your pooper doesn't count btw.)9 -
I have created a small system of care records for the provider i wich i work. I did It because i realized it would be useful and much more pratical. After being ready and properly tested, i introduced the supervisor of my sector. Their words were the followers: "I think at the moment se need something more pratical and simple."
Imagine how frustrated i was. I made the entire system of free Will spontaneously, so that a supervisor who does not know or make a RJ45 cable(is TRUE) disapprove only because he was jealous of something i did for the good of all.
I was a supervisor of the same type of sector in my old job, and frankly, If i had a programmer on my team, i was GLORIFYING FOOT!!!
How to proceed...
