Hi, I was running fail2ban now for about one year. Suddenly it stopped working. Does anyone know what could be a reason? I tried to restart it but the same. I tried to stop iptables and than stop fail2ban, that start fail2ban. In log everything is fine. [root@fs1 log]# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination fail2ban-freeswitch-tcp all -- anywhere anywhere fail2ban-freeswitch-udp all -- anywhere anywhere Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain fail2ban-freeswitch-tcp (1 references) target prot opt source destination RETURN all -- anywhere anywhere Chain fail2ban-freeswitch-udp (1 references) target prot opt source destination RETURN all -- anywhere anywhere [root@fs1 log]# 2012-10-19 14:59:46,009 fail2ban.server : INFO Changed logging target to /var/log/fail2ban.log for Fail2ban v0.8.4 2012-10-19 14:59:46,010 fail2ban.jail : INFO Creating new jail 'freeswitch-udp' 2012-10-19 14:59:46,011 fail2ban.jail : INFO Jail 'freeswitch-udp' uses Gamin 2012-10-19 14:59:46,026 fail2ban.filter : INFO Added logfile = /usr/local/freeswitch/log/freeswitch.log 2012-10-19 14:59:46,026 fail2ban.filter : INFO Set maxRetry = 3 2012-10-19 14:59:46,027 fail2ban.filter : INFO Set findtime = 600 2012-10-19 14:59:46,028 fail2ban.actions: INFO Set banTime = 600 2012-10-19 14:59:46,038 fail2ban.jail : INFO Creating new jail 'freeswitch-tcp' 2012-10-19 14:59:46,038 fail2ban.jail : INFO Jail 'freeswitch-tcp' uses Gamin 2012-10-19 14:59:46,039 fail2ban.filter : INFO Added logfile = /usr/local/freeswitch/log/freeswitch.log 2012-10-19 14:59:46,039 fail2ban.filter : INFO Set maxRetry = 3 2012-10-19 14:59:46,040 fail2ban.filter : INFO Set findtime = 600 2012-10-19 14:59:46,041 fail2ban.actions: INFO Set banTime = 600 2012-10-19 14:59:46,051 fail2ban.jail : INFO Jail 'freeswitch-udp' started 2012-10-19 14:59:46,054 fail2ban.jail : INFO Jail 'freeswitch-tcp' started 2012-10-19 15:06:10,585 fail2ban.filter : INFO Log rotation detected for /usr/local/freeswitch/log/freeswitch.log 2012-10-19 15:06:10,608 fail2ban.filter : INFO Log rotation detected for /usr/local/freeswitch/log/freeswitch.log I tried with wrong pass but fail2ban does not ban ip (I also look in white liste, but there is no problem). Thanks! Miha
