Could not determine Asterisk version (got: Asterisk GIT-master-2fd0a875d4 built by root @ myhost on a x86_64 running Linux on 2018-06-30 16:00:25 UTC). Please report this

No luck getting Fail2ban to work. Using the how-to from the Wiki and assuming v1.4/1.6 of asterisk.

You’re using asterisk 15. Not 1.4 or 1.6. Very old versions.

Whose Wiki is that? It’s no less than 10 years old and we’re 9 versions past there.

Yea, I see when this one was posted.

I’ll keep looking for a more recent how-to. Maybe something with UFW and Fail2Ban
