failregex = USER \S+: no such user found from \S* ?\[<HOST>\] to \S+\s*$
/var/log/secure:Jul 3 14:33:30 xkmail proftpd[12639]: xkmail.hopto.org (pe1950-2.sni.ne.jp[61.7.1.109]) - USER adriana: no such user found from pe1950-2.sni.ne.jp [61.7.1.109] to 71.105.58.80:21
I got hit by this about 1400 times today but fail2ban did not jail ip address.
Is the jail.conf wrong? kevin@xkmail.hopto.org ver .80 fedora 4

As Yaroslav Halchenko mentioned right in the mailing list each failregex has to contain \s+$ at the end, expect the one for "no such user found from" there is a \s* for zero or more whitespaces needed.

I've just tested it with fail2ban 0.8.2-3 on Debian etch 4.0 Before this change i had also the problem, that fail2ban didn't react on bad login attempts on ftp.
Please do not ask for help here. There are instructions here. Thanks. --Lostcontrol 13:58, 5 July 2007 (CEST)
