#adventuresinselfhosting — Public Fediverse posts

In today's #AdventuresInSelfHosting: Good lord, I made _ONE_ networking change to my NAS and it completely borked the entire networking stack of the machine. It's been four hours of working on this.

After troubleshooting on my own and with the MFG, the only fix is to reinstall the OS. OMG. Lesson learned: stop touching shit if it's working.

Upgrade to mastodon 4.4.0+glitch GET!

Lots of new stuff in this release that I need to delve in and see if it's of any use.

I guess it is not a good idea to install #postgresql without a version on #alpine, as it's more than happy to just install the v17 and remove the v16 binaries - without doing any sort of migration.

Had to roll back the container to the snapshot taken this morning. To avoid the issue again, I've moved the Alpine packages explicitly to v16. I'll tackle v17 another day.

I suppose just running software upgrades via Ansible overnight is maybe not the best idea, either. :O

Now that I've built a Proxmox cluster at home, I figure I should be moving my networking among them and the NAS from 1G to 10G.

My coworker at the office who runs the connectivity lab gave me an old 3850-12XS switch (we only use 9k's now) and a few Cisco VICs from an old WiFi controller to see if it would work in my setup.

SUCCESS! I've got Jellyfin transcoding video on a supplemental GPU. Even the lowest tier Intel ARC A310 GPU has no issue handling HEVC to H.264.

Finally cracked the code on setting up an XMPP (chat) server for my domain. It seems to be a bit more lightweight than Matrix, tho I don't know where to find any chatrooms in the XMPP world at the moment.

It's a month in, this instance is gonna stick around :blobfox_w:, so I suppose I should introduce myself to the world.

As it's probably apparent from my fedi handle, I'm Chris. I'm a 40-something network security engineer in the north east US, but I'm mainly here to relay my #AdventuresInSelfHosting my own platforms. (No company info.)

I might also dribble on about my personal interests, such as the #Eurovision Song Contest and the #RatchetAndClank video game franchise on PS.

#introduction

I should probably find a method to reliably backup my ProxMox VMs. I take backups whenever I'm about to make a potentially breaking change, and then again after that change is done, but I ought to make backups of them more regularly.

They are just LVMs inside of the ProxMox server. I shouldn't need a $495 "ProxMox backup server" in order to do this easily.

Trying to find a way, with Ansible to have the pfsense router (with my letsencrypt certificate store) to replicate said cert files to the internal systems that need it.

Allegedly I can do this with ansible.posix.synchronize (which uses rsync) but no matter where I have the SSH keys, the synchronize task always fails with an unrecognized host key.

ansible.posix.synchronize:
src: (source file)
dest: (destination file)
delegate_to: pfsense

What am I missing?
