When I started with an Ubuntu home server, fail2ban was a lifesaver - alerting me to multiple attempts at unauthorized SSH access to my server. Recently, after moving to a way off port, the only thing fail2ban bans is me. Specifically, whenever I use FileZilla for SFTP to try to download multiple items off my home server, I get banned right away, even though I correctly entered my password.
It looks like I'm not the only one who has been affected by this issue: http://sourceforge.net/p/fail2ban/mailman/message/32194650/ - but this thread ends with no solution, and I'm not sure how fail2ban-regex will help anything.
Is there a way to permanently whitelist a certain local IP address as a fail2ban exception? Or, better yet, get fail2ban to stop banning legitimate use that was properly authenticated? (Or is this a bug with f2b or filezilla?)
My home server runs Ubuntu 12.04, with fail2ban 0.8.6-3wheezy3build0.12.04.1
My clients run a variety of operating systems, but the one that's been getting banned most often recently is running FileZilla 3.10.3 on Windows, but this has also affected other clients.
