If you’re setting up Proxmox either use the Proxmox ISO or start with Debian Bookworm. The only Linux machines I have with a GUI are my desktop and my laptop, both running Debian with KDE. All my servers run Debian unless there’s a good reason not to.

I found myself in a similar situation last year. MXRoute’s lifetime plan works well for those domains that just need basic email and not a lot of storage.

I don’t, but I’ll run some and try to remember to post back.

Nice writeup. As long as you can throw fast drives, fast networking and plenty of RAM at it Ceph is happy.

Ceph seems to work fine on my cluster at work. For less than $40k I replaced my whole VMware vSAN cluster and we’re saving as much again in software licensing over the next 5 years with buying support from Proxmox. Also much lighter as far as administrative tasks to keep it up to date and running well.

One would assume they mean sitting around, doing nothing. Some would rather use some electricity to support a good cause than have the computing power sit there idle.

There are alternatives. Akamai has a similar product. It’s not free, but it works. Also doesn’t require all traffic to go through them all the time, you can repoint your traffic at them on the fly and have them mitigate by scrubbing the unwanted traffic until the attack ends and then switch back, and this can be automated. My ISP at work uses this as they have large swaths of public IP address space to protect for vulnerable members.
