From: "Ashley M. Kirchner" For example, I have absolutely no problem what so ever blocking the entire network belonging to Media Dream Land (69.42.96.0/19), who are just a big ass spamming network. You can all start flaming me now.
This is a pre-flame against anyone who disagrees with you! You are so right.
I'm using an external router/firewall, but the information is still incredibly useful. Between the Linux/Fedora community and grc.com I'm getting much useful knowledge against the crackers ("hacker" used to be a compliment), spammers and other evil cyber-folk.
One thing the original poster seems to have discovered:
Jul 17 14:42:27 localhost sshd[6748]: Illegal user guest from 130.120.81.14
Jul 17 14:42:30 localhost sshd[6748]: Failed password for illegal user guest from 130.120.81.14 port 48753 ssh2
is that Linux security is fairly strong against such attacks, provided of course you don't have a hackable "test" or "guest" username.
Another lesson is that it's dirty and dangerous out there in cyberspace. You've got to actively and diligently protect yourself.
It is often a Linux hacker (in the complimentary meaning) who cares about, discovers, analyzes and requests advice on such intrusions. Thus this list is helpful even for non-Fedora folks.
