I (took over and spruced up, to be precise) this community specifically because of the time I've spent over the years browsing and relying on reddit.com/r/sysadmin for sources of information on tips/tricks, security exploits & patches, outages, and yes even the ranting about how our jobs all suck. (I like mine, for what it's worth.)
Instead, I want to take aim at a misconception that I think Pablo shares with many, many people in the software industry. Namely, the idea that if a software system is built correctly, it will work. Or, equivalently: if a software system doesn’t work, then it wasn’t built correctly.
Greetings! I've recently made the switch from shitbuntu (ubuntu) to alpine on my home server. However, while i was configuring the openRC service for my discord bot to run, i wanted to run 2 more. And for some reason, after i created 2 more services, only one of them runs. The other ones i made do not.
All our servers *and* company laptops went down at pretty much the same time. Laptops have been bootlooping to blue screen of death. It's all very exciting, personally, as someone not responsible for fixing it.
I am working part time for a small company, they have about 40 employees that use the email everyday for work and recently they have acquired a MS account for 10 employees that use it mainly for teams with customers but also sharepoint, etc.
I’ve started at a medium-sized org (~1500 users) that has over a dozen global admins in 365, plus another 80 users with various 365 admin access. Does anyone have any tips for how to identify what access the users actually need?
Hopefully not a lot of you had their business use BlueJeans as their core videoconferencing software. Because if you do, you’ll want to plan a migration soon.
As a sysadmin mostly used to the nice and powerful way Postgres manages dates, every time i’ve had to do stuff on SQLite i find myself missing that. Feels like they offloaded that into whatever code connects to the database instead of handling it at DB level.
I have 15 VM's running for clients and I'm looking for a way to keep the tools up to date without having to connect to each server and do it manually. A few examples are WinDirStat, Firefox, SSMS, Filelocator, etc.
So, I have a VM DC that I had to restore from a month ago. I had other DCs that were physical and up. My understanding that if sub 60 days "off" it is fine to basically "power back on" the snapshot. However, now the "restored" DC has disabled replication in both directions. Should I manually enable inbound replication first and then after a while enable outbound replication?
Hi! I've inherited a machine installed by somebody else who's no longer in the company *or* the country. The machine is running just fine, but i see no Dockerfiles or docker-compose.yml, and this looks like something that came from a Compose file with a few linked containers.
This really doesn't make me love cloud identity management. It's exactly the scenario (kind of nightmare one) where you attack the cloud infrastructure and get access to many different customers and apps... potentially in a way completely undetectable by you. At least with local identity providers they have to compromise you, and you might have logs.
I’ve been working on a project that I need constant access (and executing commands) among at least 3 hosts in work. I’ve been using SSH’s Host function to manage which host I’m connecting to. However, I find it increasingly annoying that I can’t see which host I’m connected to via the tab on my terminal emulator (I’m using Windows Terminal on Windows and Konsole on Linux).
Hello c/sysadmin, and welcome to the Patch Megathread! I'm editing this post and leaving it up as a single catch-all sticky post for patch days for the time being, since we're not seeing enough activity to warrant new threads IMO. If someone wants to help moderate / curate content and actively create new patch day posts, please let me know and I'll add you to the mod team.
Hey all, in my company we've been having a lot of trouble with our first-line support team and I wanted to get some ideas how it works in other companies.
Suncor is replacing employee computers after a cybersecurity incident last week shut down debit and credit processing at Petro-Canada gas stations across the country, among a series of other security measures at the Calgary-based company.
I got my new PC for about 3 or 4 months. Today, I was using my PC as usual and suddenly everything stopped reacting. Rebooting just boots be into the UEFI interface. Which is very concerning.
Monitoring and observability tools commit the cardinal sin of tricking people into thinking monitoring is an easy problem. It is very simple to monitor a small application or service. Almost none of those approaches scale.
Hey like the title says I'm looking for a way to keep up with outages and vulnerabilities. I mostly used r/sysadmin to alert me to things, but given everything I don't want to go to reddit if I don't have to.
Service accounts in Kubernetes are used to provide a secure way for applications and services to authenticate and interact with the Kubernetes API.

Hi guys, I recently started working at a company with about 50 people that has grown to large for their current IT setup. They have no documentation or any SOPs. Has anyone been in a similar situation and how did you go about creating documentation, especially when you are new and don't fully understand all of the services they have in place?
I started a new job as a systems engineer not too long ago and am looking for a way to get comfortable with FOS as I've never had to manage FC switches before. Anyone know of a way to emulate it, or should I just resign myself to buying an old switch on ebay and throwing it in the rack?
I sometimes have to use remote systems that I don't have root access to. I often find that I need to install packages in my home directory, so either I build from source or copy over my own pre-compiled versions.
A buffer overflow vulnerability was found within SSL-VPN in FortiOS leading to unauthorized code execution. Options are either to disable SSL-VPN or upgrade to a patched version.
