Sysadmin

Today I announced on the company wide Slack channel that, effectively immediately, we were rolling back to Windows XP. There were cheers! and then a lot of disappointment when I said it was just April fools Lmao

I was gifted a R720xd by work (yay!) and want to install a spare 3060 I have. Does any one know of a power cable and advice? Do I hook the power to the riser, the card, both?

Luckily the RCE only works if the device is domain joined which is against Veeams Best Practices.

Silly question: Having CNAMEs for A records just makes sense, but why can't we have a PTR redirect?

I go to investigate, and they had managed to plug the HDMI cable of one monitor into the other monitor.

I was recently looking for broken links on my websites using ahrefs tool, but it kept asking for money. I realized how easy what they were doing is to implement, so I did it myself.

That's how I made crawlr. It will recursively search all of the urls on your website save them into a csv file with their status code and let you know how many urls are broken.

It is written in go and is extremely fast. It takes a couple of seconds to index a couple hundered of urls.

Give it a ⭐ if you like it

As IT leaders move away from VMware, they face a critical decision: do they stick with traditional storage architectures, or is now the time to finally unlock the full potential of an infrastructure that converges virtualization, storage, and networking technologies?

Early convergence efforts centered on hyperconverged infrastructure (HCI), where storage ran as a virtual machine under the hypervisor, commonly called a vSAN. While adoption has lagged behind traditional three-tier architectures, recent advancements have significantly improved vSAN, making it worth reconsidering by addressing past shortcomings.

Hi all

I have been searching high and low but I think my search game is too weak. I am looking for a tool (similar to Uptime Kuma) that can monitor multiple systems via their own APIs, to centralise the status of these devices. Ex:

a) I have a sensor system that monitors a whole bunch of sensors across multiple locations. This system has an API that uses a secret key + api key for auth, and I can get the status of the sensor via the api. The idea is that the central dashboard shows the status, if offline, the control room personnel can log into the sensors system itself and determine root cause.

b) I also have a system to which a whole bunch of A/V equipment is connected, and via it's API I am able to view the status of multiple devices on the A/V equipment network. I want to also see on the status of these devices on my central monitoring system.

I don't care about doing root cause analysis via the central monitoring system, I just want the statuses which can action a person to check via the control system of that particular service.

All my searches come back with hits of systems that can monitor whether my APIs are up and running, but that is not what I want. Does anyone have any ideas? Preferably opensource, but definitely self-hosted/on-prem hosting. TIA

Please share your tips and tricks with me. I would love to hear them and use them.

Any feedback is welcomed.

I have been self-hosting for a while now with Traefik. It works, but I'd like to give Nginx Proxy Manager a try, it seems easier to manage stuff not in docker.

What are industry best practices for this stuff? Do you want a separate fabric for dev and prod? Just separate zones?

My company doesn't connect any fabrics (1 switch=1fabric) and it seems inefficient and a giant pain in the ass, as we move hosts around like we're getting paid for it. What do all of you do?

In the middle of a live VLAN readressing of a 200-node company, I encountered this gem. The ports just kept blinking on even after plugging out the cables. (HP aruba 24 port switch)

One turned off after a reboot.

Here it is:
