Somebody trying to Break into my server
I'm using Red Hat. It's been going on for a long time, and I'm getting tired of adding ip's to hosts.deny. They must be using proxy ips or something. If anyone knows any good methods on how to prevent this, I would appreciate it very much.
This is a sample of what's in my /var/log/secure file:
