so annoyed rn i inherited a Azure DevOps agent nobody has touched in a year. today the test stage failed with ENOSPC and the disk looks like this: I'm scared to delete anything because I don't know what's safe ;) The whole team is blocked and looking at me.…
so annoyed rn were a school district and use number matching for MFA today 🤦 After hearing about push bombing attacks, Im wondering whether were as protected as we think. Users approve things without reading, and phishing kits proxy everything anyway. Whats…
long time lurker first post lol imagine finishing an in place OS upgarde on the primary site sevrer over the weekend, feeling proud, and then on Monday morning opening teh console to this: what am i doing wrong??
hmmmm ok inherited a ConfigMgr single pirmary site :) The previous admin warned me that WSUS is 'fragile'. Now the sync fails every night: ive restarted the server... it worked once, then failed again... id love to understand whats going on rather than…
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…
hmmmm ok a remote salesperson changed their password on Monday. Since then the account locks right after a password change: we suspect something is still using the old password, but they have a laptop, a phone, a tablet and who knows what else. how do we…
ugh. I've been tasked with converting it from a physical machine for an old server, now running on Hyper V. Everything looked fine until I powered it on: the virtual disk is attahced and the right size. the original machine booted fine yesterday. where did…
so annoyed rn a remote salesperson changed their password on Monday. since then the account locks every time they open Outlook: we suspect something is still using the old password, but they have a laptop, a phone, a tablet and who knows what else, how do we…
a developer changed their password on Monday. Since then teh account locks every 15 minutes: we suspect smth is still using teh old password, but they have a laptop, a phone, a tablet and who knows what else. how do we narrow it down? Weve already asked them…
ok weird one we need to enable multi factor authentication for all staff at our small business 😭 my worry is the practical side: people getting locked out, teh support load, staff without company phones. Any advice…
ok weird one migrated the Node.js API from a VM to containres. On the VM it was fine for years. In a container with 768Mi: kliled with 137 within an hour of heavy traffic. same code, same traffic... what changed? on the VM, nothing ever complained. i suspect…
question for people who've been through it: for a agency with a couple of APIs and a database, did moving to Kubernetes pay off? i'm interested in the operatinoal reality: upgrades, debugging, on call, not the conference talk version. im not against…
PXE was working last week at the imaging bench. then teh network team swapped a switch, and now Surface devices show this: They say teh network is fine... i say it isnt. Whos right?? Ive already redistributed teh boot images and restarted teh WDS service on…
ok so every run of my Ansible playbook shows lots of "changed" tasks, so I cant tell what actually changed. The tasks use shell commands for things like adding lines to files and restarting services. what are the usual…
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…
Small office, 10.10.20.0/24 network. Since last week the network printer disconnects every few hours, and a nearby PC shows this: rebooting fixes it temporarily lmao nobody admits to changing anything :/ i suspect something has teh same IP, but how do i find…
long time lurker first post lol the marketing lead changed their password on Monday. Since then the account locks every time they open Outlook: we suspect something is still using teh old password, but they have a laptop, a phone, a tablet and who knows what…
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…
CI pipeline went red overnight. The job that spins up the dev API on a fresh Ubuntu box fails with: it passes on retry sometimes, which makes it even worse. i suspect leftovers from earlier jobs but i can't prove it. Our pipeline runs several jobs at once on…
hmmmm ok well. our small team has API keys and database passwords scattered around: some in CI variables, some in .env files on servers, and (Im embarrassed to say) a couple committed to a private repo at some point.…
before anything else: using a three node consumer mesh at home. connected wirelessly between nodes. throughput near the satellite nodes is noticeably lower than near the main one, especially the furthest one. Wondering…
not gonna lie this is driving me nuts PXE was working last week at teh new building. then teh network team swapped a switch, and now Surface devices show this: They say the network is fine. i say it isnt. Whos right? ive already redistributed the boot images…
long time lurker first post lol rolling out 40 laptops. the client install via the task sequence fails over and over: the error is 0x80004005 😂 our consultant set this up years ago and left... i know just enough ConfigMgr to be dagnerous... where should i…
