#linuxadmin — Public Fediverse posts

I've been hosting more of my own stuff over time, but keeping up with the maintenance manually has been proving to be too much. I remember 100 years ago as a sysadmin setting up an Ubuntu management server to manage the fleet of Ubuntu servers at work in the style of the Red Hat stuff that did the same. Now I run a variety of instances, and I don't know what kind of orchestration machine I would need to spin up to keep things like OPNsense, remote *nix hosts, etc. up to date. Any recommendations?

My goal is to use only FOSS whenever possible (leaning towards things on Starlight's NO AI list so I can avoid slopcode running in my network wherever possible.

And here's another one:
https://github.com/0xdeadbeefnetwork/Copy_Fail2-Electric_Boogaloo

This one is not fixed by f4c50a40, so all current kernels are vulnerable. Looks like mitigation is possible by blocking kernel modules `esp4` + `esp6` here as well (and breaking #IPSec in doing so). Can someone confirm?

Why is it called "Electric Boogaloo"… is this a #DonaldByrd fan? Were they inspired by this week's @thekalimerashow shows??

Here we go again :-/ Another deterministic #privilegeescalation bug in the #Linux kernel. Make sure you're using at least the following version of your branch to mitigate against #dirtyfrag:

- 7.0.5
- 6.18.28
- 6.12.87
- 6.6.138
- 6.1.171
- 5.15.205
- 5.10.255

6.19 is eol, so it probably won't get patched. Remove and blocklist the following modules if you have to use an unpatched kernel: esp4 esp6 rxrpc

See https://github.com/V4bel/dirtyfrag/blob/master/README.md for more info.

I couldn't find a list of #Linux #kernel versions that include a patch for #copyfail, so I dug into the commit log and made one. Make sure you're using at least the following version of your branch to mitigate against copyfail:

- 7.0-rc7 (any stable 7.x is safe)
- 6.19.12
- 6.18.22
- 6.12.85
- 6.6.137
- 6.1.170
- 5.15.204
- 5.10.254

See https://copy.fail for more info about the #exploit.

Funny enough Mozilla Firefox :firefox: supports DoH and sets it up on application level, while Android :android: uses DoT on operating system level :blobcatnerd:
