My externally hosted vserver runs with Debian lenny stable. Fail2ban 0.8.3 (and iptables) have been installed with the package-manager. The intention is to use fail2ban with the messages-file from asterisk, i.e. without iptables. The configuration files for fail2ban are according this howto. When I start fail2ban with /etc/init.d/fail2ban start no further information is given, so I thought it would work. Later I questioned whether it would require beforehand a /etc/init.d/fail2ban reload or a /etc/init.d/fail2ban restart and in both of these cases I obtain each time the result "failed!" How could I find out what is going wrong? Note: I'm not very familiar with Linux, I only use it in the context of the asterisk.
