hello, shown below is snapshot of too many illegal attempts to login to my server from a suspicious hacker. this is taken from the "/var/log/auth.log". my question is, how do i automatically block an IP address if it is attempting to guess my login usernames? can i configure the firewall to check the instances a certain IP has attempted to access/ssh the sevrer, and if it has failed to login for about "x" number of attempts, it will be blocked automatically? thank you in advance! -edwin ---------------- Mar 26 05:00:00 pawikan newsyslog[11879]: logfile turned over due to size>1= 00K Mar 26
