Ole,
I have attached the fail2ban.conf and the jail.conf file. I am running
the following:
*> uname -a*
Linux laetitia.area510.net 2.6.18-128.7.1.el5 #1 SMP Mon Aug 24 08:20:55
EDT 2009 i686 athlon i386 GNU/Linux
*> rpm -qa|grep release*
remi-release-5-4.el5.remi
centos-release-notes-5.4-4
rpmforge-release-0.3.6-1.el5.rf
epel-release-5-3
centos-release-5-4.el5.centos.1
Have a great weekend.
Cheers,
CJ
