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
