    I want to "protect" from brut force attack.

    My idea is:

    If there is 10 unsuccessful logins {
    add firewall rule "disable ssh port for attacker IP"

    How to do this on centos 5.1 with ISP config (because firewall is disabled)?

    have you done the simple thing of changing the port that the ssh is on
    that will also help out big time
