Hello everybody,

Someone is attacking for a certain time on port SSH2
He is trying to login as root and uses all kind of usernames.
See annexed textfile


How can I block a user after x failed logins?
Can I do something else?

You can reconfigure ssh to listen on another port, and set up portsentry to automatically firewall anyone who's hammering on the default ssh port.
