Project mention: Alternative to MailCow | /r/selfhosted | 2023-06-04

I can recommend Docker mailserver (it also works with Podman). It is already pretty lightweight but you can even make it lighter and it has an active community as well as regular updates.

  Drop repeat-offending IP addresses in-kernel (netfilter)

Project mention: Fail2ban Sucks | news.ycombinator.com | 2024-01-01

I think ssh on a non-standard port is a no-brainer, have been doing this for years.

But at some point I got too many log entries of failed ssh access attempts. So I looked into fail2ban, but found the system too involved, and I don't like python for this kind of thing to start with. Then I started looking for alternatives, because I figured you only need something very simple, that checks certain log files and then instructs the kernel through netfilter to drop traffic from all infracting IPs. I like single-binary applications, especially for things installed outside the normal package manager. Found a skeleton of a golang app that claimed to work (it didn't), but I managed to rework it, and it serves my use cases: https://github.com/pepa65/fail2drop
