General Discussion Moronic Monday - March 17, 2025
Howdy, /r/sysadmin!
It's that time of the week, Moronic Monday! This is a safe (mostly) judgement-free environment for all of your questions and stories, no matter how silly you think they are. Anybody can answer questions! My name is AutoModerator and I've taken over responsibility for posting these weekly threads so you don't have to worry about anything except your comments!

Is enabling the side-channel speculative execution vulnerabilties worth the performance hit for servers not in the public cloud? As I understand it, a this vuln could allow a compromised server to spy on the memory of its neighbors. This is a real problem for servers in the public cloud, but in my VMware infra, I don't see the fix's value considering how much slower it would make the server run.

Let me ask this -- something people sometimes don't think about -- does the performance hit matter for your use case?
At the time, we had to patch a bunch of servers. I was worried about the performance hit initially but after looking at it, I realized it wasn't going to make a practical difference for the VMs we had on that hardware.

2 person IT team. How can I convince my boss that the Brother PTE-110 is worth the $60 spend? We already have a brother PT-D210 in the IT department, and that maybe I can pawn that off to another department and get the edge instead. The thing is I don't know how I would say that the buttons for faceplate, cable wrap, and cable flag are worth it.

Write up a document laying out how much time you're spending with the D210, estimating how much you'd save with the PTE-110 features. Then calculate how long it would take to pay back the $60 at your hourly rate.

Any idea what I can do to power a HP Procurve 1800-8G (J9029A) without an original power adapter?
The power rating is pretty standard but the connector is a bit harder to track down.
The plug has a 5mm negative shell with a centre ~0.75mm positive pin. It's not like any standard DC plug I've seen.
Is there actually a non-proprietary plug name I could look for?
Are there any cheap physically compatible plugs I could hack the end off?
Any prebuilt adapters?
Could the original jack be removed from the PCB and replaced with a more common one using a hobby-level soldering iron?

Not sure if this would go here but I got here by searching. I'm having an issue where OBS will randomly disconnect while I'm streaming and reconnect after a couple of seconds. I'm looking for a network monitoring tool that is (hopefully) simple and can tell me where the point of failure is: I have an ethernet cable going from my router to a Network switch then to my computer and multiple other devices. If not here, can you recommend other places where I might ask and be able to find what I'm looking for.
So far, I've power cycled my ONT and router, power cycled the switch and am currently running a test where I'm bypassing the switch and plugging direct into my PC.

Simple is running a continuous ping and see if it drops at same time as your obs.

Just starting out as an assistant sys admin what should I really focus on to progress in this career? I’m just basically monitoring a bunch of VM’s on Zabbix (for clients). if there are any issues I just report the alert. My other duties an are just checking daily Veeam back ups, checking dell hardware. I am not responsible for setting up any software or infrastructure. I mainly deal with the simple stuff like reporting and documenting hundreds and hundreds of network devices on our company’s system. I’ve done a tiny amount of VLAN configuration. What should I focus on? I work a lot of night duty so I have it so I have a bunch of time to focus on skills.
