Sysadmin

Hi sysadmins, I am thinking of doing a pretty drastic career change. I have 10+ years of experience in chemistry doing bioanalysis and a few years repairing breath alcohol analyzers. I have always considered messing around with electronics, networking, and computers/servers as a hobby and have been using various Linux distros as my main os for almost 20 years.

Projects like Arubis use a web based proof of work to slow down and and potential stop not traffic. The idea is that the proof of work makes the client spend some computer resources accessing the page so that it isn't as computationally feasible to abuse public websites.

I have a SMB share on a computer. It's set to anonymous access, meaning I don't have to enter a password to access the shares. All my PC's at home are Linux so this has served me for many years. I now have a Windows 11 laptop from work that refuses to connect to this device. The message it gives me is you can't access this shared folder because your organization's security policies block unauthenticated guest access

I need to replace a bunch of ancient Cisco stuff. Also looking at other brands like Dell, Juniper and Extreme

I posted last week about building a NAS, and on friday I saw that the Jonsbo N4 case I had been eyeing for a while was in stock at a good price.

I am sorry if this the wrong community to ask in, while I have been on Lemmy for more than a year now, I am still learning my way around, and this seems like a relatively active community in a relevant area.

After decades of using the standard mouse cursor in Windows, and loosing track of it more and more as displays and resolutions grew, I have finally changed it to black and increased the size of it one step.

The first email of my day was sent to our head of HR asking what their hiring projections were for the next 6 months-1 year (usually I just get 1-2 months advanced notice) so I can shore up our tech stock

From a simple KeePass database to enterprise credential management solutions—what’s your setup at work?

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?

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.

Hi all

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?

Here it is:

Essentially, I'd like to have pictrs delete all of the images that aren't uploaded by my users, because my storage usage was going through the roof, so I just disabled the proxying of images. Here is my config:

Went to do a test restore of one of my databases and I noticed the dump files over the last few months were all 0kb. Glad I caught it this way and not because I needed to restore. Put it on your calendar, schedule a test restore of your critical stuff a couple times a year. I know y'all are busy but it is worth the time and effort. A backup you can't actually restore isn't a backup at all.

The storage usage is at 340GB currently, which is a lot and it's rapidly increasing. I use Backblaze B2 for my storage. Here is my docker compose file: x-logging: &default-logging driver: "json-file" options: max-size: "50m" max-file: "4"

Windows Server 2022 creates one recovery partition just on the right of the C: partition. So, when it is required to expand the C: partition it is impossible due to this recovery partition. I realised of this problem because our IT department provides Windows Server virtual machines users are unable to expand.

If you're in the U.S. anyway.

I was literally told to set up this new service as quickly as possible and it didn't need to be correct or best practice because this was just a proof of concept.

Let me tell you about the hell that is Roku. They create so much wireless interference and I can't just get rid of them.

What are you guys working on? Anything new in the world

Doing a PhD in humanities and enjoy it. I’ve recently really started to enjoy Linux, self hosting, and messing around with various lab stuff.

Anyone here have any experience with a Datto Backup Appliance?

As you all might be aware VMware is hiking prices again. (Surprise to no one)

That’s sounds strange to say but hear me out. Before ransomeware there was no economic incentive for companies to worry about security. There was a strong “why would you hack us” vibe that made it hard to talk management into doing anything basic like locking down ports.

So using qemu with hyper-V acceleration is something that is not well documented. Historically, you would setup HAXM but that has been discontinued and deprecated.

So we run VMware, and this morning I go and check a thing, and Firefox gives me an error.. connection insecure cert is invalid

Took me a few hours to figure this out, figured I'd pass it along. Forgive formatting, I'm on mobile.

It keeps showing Internal server error and has been for over 2 hours now. I tested from different locations (China, US, EU) and same errors everywhere. Yet I don't see any news or posts about this anywhere. I have an exchange server that needs installing today and I can't download the prerequisites to even launch the install. Sigh

Just a quick fyi for anyone using Intune to distribute firewall rules with the "Endpoint Protection > Windows Firewall" profile for the first time. Any rules you set won't be visible in the wf.msc GUI or using PowerShell's Get-NetFirewallRule.

So I have been a part of this community for a while and it seems pretty quiet. I know Lemmy is not as big as Reddit so this community will always be much smaller but I kind of miss the activity on r/sysadmin. Infinity for Reddit still works for view only so I have been scrolling though posts on Reddit as some of the stories and discussion there are fun to read.

Hello friends. Work email is crushing me. The ticketing systems, plural, email me on everyone's tucket. (Because some people only work tickets via email and others through the web interface.)

Hello everyone, I hope I came to the right place to ask my stupid question. I'm currently working in a company that stuck way way back in time. I'm talking *some people are still working in DOS* level back in time. There is some revamping of this in progres, but it's going to be a long run.

Hello!

I have created a new Samba community on lemmy.sdf.org

The location of VMware Security Advisories (VMSAs) has changed on May 6, 2024. They are now available from the Broadcom Support Portal. The legacy VMSA URLs still work but are now redirected to the portal, for example: https://www.vmware.com/security/advisories/VMSA-2024-0002.html points to https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/23681.

Samba is amazing, Windows server is a lot less so. The problem with Windows server is that it takes tons of steps to do basic things. On Samba I had Samba tool and it was very nice and friendly. On Windows server you have a ton of different management panels.

Hey all!

I received the below message. It states Skyline Advisor Pro can't be activated after 4/1. This doesn't look good for the Skyline program. I've been using it for a long time and between log assist and the recommendations, i've found it very helpful. I have the Dell integration in place but I haven't really used it much. It's unfortunate that this appears to be getting set out to pasture.

Basically what it says in the title. I did a lot of searching in Internet. I think small form factor computers are mt best bet. But I still feel they are costly for my purpose.

Debian has less complexityand is very stable. It has a nice wiki and a Debian system can run for a few years on unattended upgrades.

Hey guys,
