Modifications i had to make to fail2ban to have it ban failed imap dovecot logins on Debian

I was having issues with fail2ban not catching invalid dovecot login attempts because for whatever reason invalid login attempts we're going into the mail.log. So, here is what I changed to get it to work.

In /var/log/auth.log the failed dovecot login attempts look like

Jan 2 19:41:14 shittie auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=derp rhost=10.0.0.1

Awesome, failed attempt. However, the dovecot filter in fail2ban (v0.8.6) for dovecot wasn't catching failed attempts even when I switched it to look at /var/log/auth.log instead of /var/log/mail.log.

so, all I did was open up /etc/fail2ban/filter.d/dovecot.conf and replace the failregex line with

Saving my Podfile structure for adding the Acknowledgements.plist generated by cocoa pods into my Settings.bundle, soon to be part of my default app template.

Searches auth.log for failed logins and adds them to hosts.deny. Probably a terrible way to do it, and it's potentially a massive failure. But i'm sick of fail2ban not banning
#!/usr/bin/env python
authlog=open('/var/log/auth.log','r')
lines = []
for line in authlog:
lines.append(line)
authlog.close()

A python script to parse the IP assignment/allotment list from Arin ftp://ftp.arin.net/pub/stats/arin/delegated-arin-latest as well as a bash wrapper designed to wrap the python script enabling different options. It creates a lot of unnecessary lines that could be combined when determining the subnet type. I haven't fixed that yet so in its curr…
