Hi all,

I have been reading and reading and reading and can't seem to find the explanation to the errors I am having. Just a little quick background. I used to have APF and BFD running (could never get BFD to block), but now disabled them. I am running Trixbox PBX which runs on CentOS.

Fail2ban log shows me the following errors:

any ideas?

Thank you
