More and more each day I am seeing my root emails contain hundreds of entries like this: May 8 02:23:35 warpstone sshd[26092]: Failed password for root from 222.185.245.208 port 50519 ssh2 May 8 16:37:41 warpstone ftpd[34713]: FTP LOGIN FAILED FROM 211.44.250.152, Administrator Basically, people are attemtpting to hack into my server often with a few thousands of attempts each day. What measures can I take to stop these attempts? Is there a way I can detect these attacks and automatically cut them off? Are any of the security ports effective against this? Thank you!
