guys pls help I have a small VPS running a website. Looking at the logs, there are thousands of failed SSH login attempts per day from all over. Nothing seems to have gotten in, but it's unsettling. Right now I log in…
ok weird one hey, looking for advice on running a game server on Linux properly. right now its started from a terminal session that I leave open, which feels fraglie. i want it to start on boot, restart if it crashes, and get backed up daily. im comfortable…
our Ruby job runner has been rock solid for a year. since heavy concurrency it dies every few minutes with this: no exception, no stack trace, teh supervisor just restarts it. customers get random failures and i have literally nothing to grep for 🤦 how do…
ugh. i need a calm person to talk me down. that's my Linux Mint laptop after switching to an NVMe drive. it just freezes there with teh caps lock light blinking. I have a live USB from when I installed it. I'm comfortable with a terminal but I've never had…
not gonna lie this is driving me nuts ive been dual booting Windows and Pop! OS for a while, and i noticed i almost never boot Windows anymore. The only reason i keep it is music production, and even that is starting to feel optional. Before i wipe the…
trying to SSH from Windows Terminal into the backup server and i get: Permission denied (publickey)... i added my public key to authorized keys, double checked it's the right one, even regenerated it once.. 🔥 password login is disabled so i can't get in any…
Fun problem! After a routine OS upgrade, a command line tool Ive used forever now does this on startup: nothing changed in the tool itself. how do i find out whether it's teh tool, a library, or the system? seriously need help here 😭
so annoyed rn our monitoring alerted that / is at 95% on a production VM. I freed some space by clearing the package cache, but its creeping back up. how do you methodically figure out what's growing? and are there…
real story: I installed Fedora for a gamer six months ago. most things just work. the one ongoing headache is fingerprint readers. I'm curious whether others have had the same experience, and whether we're honest enough about the rough parts when we…
not gonna lie this is driving me nuts home lab drama. Debian on my cloud instance got a kernel update and now it panics during boot: It was running for months without a hiccup. Is this hardware failing at the worst possible time, or the update? i haven't…
im literally losing my mind here our monitoring box started failing right after a backup run.. lmao services refuse to start, package installs fail, and monitoring shows: df h confirms /var is at 100%. I dont want to just rm things randomly on a production…
our metrics exporter.service keeps flapping. it starts, crashes, restarts, and finally systemd stops trying: i see status=217/USER in the status. The app logs to its own file, which stays empty, sooo it dies before it even gets going. Id like to understand…
hmmmm ok genuine question, not trying to start a war. for people doing programming: are you on Windows, macOS, or Linux, and would you switch? im tempted by Ubuntu because my laptop feels slow on Windows and I like the idea of controlling updates. but I…
My key works on every other server. On a new EC2 instance, from a CI job, nothing: A colleague set up teh account. They swear they pasted my key. I'm starting to suspect the server, but I don't even know where to look. It's frustrating because I can't see…
ok weird one my custom service fails during boot but starts fine afterwards by hand. i suspect its starting too early and smth isnt ready yet, but Im guessing. How do ppl dig into this properly? Id like to understand…
not gonna lie this is driving me nuts i wrote a simple unit file for our app. Running the command manually works perfectly. Running it as myapp.service: systemctl status shows status=200/CHDIR and that's it. No useful message. I've reloaded teh daemon a…
ok weird one home lab drama. fedora on my cloud instance got a kernel update and now it panics during boot: it was running for months without a hiccup.. ;) is this hardware failing at teh worst possible time, or the update? i havent touched teh hardware in…
long time lurker first post lol I'm a backend dev, not a C person. Today my Ruby job runner started crashing after heavy concurrency, and all I get is: Our own code is plain high level code. I don't manage memory anywhere xD So how can it segfault? Is the…
Reproducible crash, at least. heavy concurrency kills the C++ API server instantly: i found a core file somewhere once but no idea what to do with it :D do i really need to learn gdb tonight? i can reproduce it in staging with the exact same input, which…
ugh. help. The database VM is barely alive. SSH works, but every command complains about writing temp files. Heres the disk: i deleted the biggest log i could find and df didnt budge... am i losing my mind? im pretty suree Im missing smth fundamental about…
help!! real story: i installed Fedora for a non technical friend six months ago. most things just work. the one ongoing headache is a specific Adobe app. im curious whether others have had the same experience, and whether were honest enough about the rough…
ugh. i was jumping between a deep project folder and /var/log over and over, typing teh full paths each time. then I learned cd . It takes you back to the previous directory, and running it again takes you back again. It toggles between two places. then i…
not gonna lie this is driving me nuts our Python worker with a C extension has been rock solid for a year. since heavy concurrency it dies every few minutes with this: no exception, no stack trace, the supervisor just restarts it. customers get random…
myapp.service was fine until todays server patching. now it wont start: the status line says status=1/FAILURE 👍 i didn't touch the unit file. did teh updtae change smth underneath? the update touched a bunch of pacakges, sooo it could be anything xD ive…
i need a calm person to talk me down. thats my Pop! OS laptop after a routine kernel update 😂 it just freezes there with teh caps lock light blinking. i have a live USB from when i installed it. im comfortable with a terminal but Ive never had to repair a…
