I also love Fail2ban (great work guys), maybe I'm missing something but is there a way to unban an IP using fail2ban-client? If not could you add this feature?
Thank you :) You're right :/ You can't unban an IP address using fail2ban-client. This will be added in the next development branch (0.9). Be patient ;) --Lostcontrol 23:23, 21 March 2007 (CET)
Fail2ban is one of the best projects I've encountered - I love it! One suggestion: in 0.7 , the iptables.conf action uses pre-ban command"
Is there a reason for this? Maybe ip spoofing? At any rate, this can cause fail2ban to take forever in implementing its actions if the iptables chains are big, because it causes DNS lookups for each entry. I suggest adding the "n" flag to the command, to speed things up, like this:
Thank you. Added in the repository. --Lostcontrol 13:21, 14 December 2006 (PST)
Seems that upon power failure, Fail2Ban fails to start when the computer reboots because the /tmp/fail2ban.sock file still exists. Perhaps this file could be removed automatically upon boot?
Fail2Ban output (like error messages) is sent to /dev/null when Fail2Ban is started during boot (at least on my Gentoo system), so it would be nice to at least be notified of the issue during bootup. Otherwise, it just says "Failed" during bootup, and it's hard to tell why. Just a thought.

IP Addresses in Documentaion
Hello, reading thru the docs and I just noticed that there are places where one should use 126.96.36.199 as an IP Address for documentation.
Refering to http://tools.ietf.org/html/rfc3330 Section 2, Paragraph 12 please do use the TEST-NET assigned numbers. I think it would save quite a few users from misconfiguring their stuff (Just search for "TEST-NET" on the page and you'll be taken directly to the corresponding paragraph.
In short RFC3330 Special-Use IPv4 Addresses:
192.0.2.0/24 - This block is assigned as "TEST-NET" for use in documentation and example code. It is often used in conjunction with domain names example.com or example.net in vendor and protocol documentation. Addresses within this block should not appear on the public Internet.
I know this is a bit picky but personally I found that it eases use of documentation (also if you use example.com and example.net domains in documentation rather than some probably not so bogus hostname)
Thank you for the suggestion. I will adapt the documentation. --Lostcontrol 23:12, 18 April 2007 (CEST)
I installed the .80 branch on my fedora clarkconnect box. Unfortunatley clark uses python 2.3, so I had to rpm it to 2.4 I had two python libraries so once i downloaded and untarred the fail2ban source I ran "/usr/bin/python2.4 setup.py install" and everything ran fine, no complaints about @staticmod. I also note my main problem is errors in my proftpd as I'm being hacked by user "administrator" unknown. proftpd logs to /var/log/secure not /var/log/ftp/proftpd as set in the default configs. Once I set my email I allready nabbed a china hacker and got an email. Thanks, I run snort,snortsam, and fail2ban and feel pretty secure.
Could you try a nightly build from trunk? It should work with Python 2.3 which is the minimal requirement for the new development branch. I haven't done a lot of work on this branch yet (CHANGELOG) and your current configuration will work without any modifications. If you try it, please, could you give me feedback (mailing-list or e-mail)? Thank you. --Lostcontrol 09:52, 29 June 2007 (CEST)
