fail2ban must be started by you.In open SUSE I would do
to start it and
chkconfig --add fail2ban
to make f2b load on startup.F2b configuration files are stored in the /etc/fail2ban directory,so there you can configure it the way you want.
Some of the configuration options are:
- ignoreip: This is a space-separated list of IP addresses that cannot be blocked by fail2ban. For example, if the computer from which you're connecting to the server has a static IP address, you might want to list it here.
- bantime: Time in seconds that a host is blocked if it was caught by fail2ban (600 seconds = 10 minutes).
- maxretry: Max. number of failed login attempts before a host is blocked by fail2ban.
- filter: Refers to the appropriate filter file in /etc/fail2ban/filter.d.
- action: Refers to the appropriate action file in /etc/fail2ban/action.d.
- logpath: The log file that fail2ban checks for failed login attempts.
If you're using Gnome,there is somewhere under System>Administration a "services" or similar option where you can add an app to be loaded on startup.There is something similar in the KDE.
