</div>It's been an extremely busy day for the exploiters. I moved my phone<br>
system from one circuit that I have (10Mb) to another that is behind a<br>
firewall (100Mb) and the fail2ban alerts are all gone.<br>
I'm not really concerned that someone will determine the passwords, as<br>
I use the phones serial numbers to determine that. But still, very<br>
irritating to see so many attempts at exploiting my phone system.<br>
fail2ban is nice, but I recommend you put your system behind a<br>
firewall and only allow necessary connections. pfsense is doing the<br>
trick for me. - Niles<br>
