how to block an IP do illegal ssh on my server? some one do brute shh to login my root..
I read old posted in this forum use this method:

/sbin/route add -host ip_address reject

or

iptables -I INPUT -s ip_address -j DROP

this method can't use permanently on server.. if server reboot all setting will flush and remove all..

There are a number of easily available apps

Root login is disabled, I hope? Disabling password based login would give peace in mind.

DenyHosts is another way to block them.
