oh sweet denyhosts...
Weekend well spent I say, quality time with Irfan & Munchkins and best of all configured denyhosts to block all those bruteforce attacks on myserver. Worked very well, immediately denied connection from about 8 hosts and blacklisted 2 new ones. And about 1500 blacklisted host from central denyhost sync server.
Failed logins from these:
 root/password from ::ffff:210.116.110.136: 6 Time(s)
 root/password from ::ffff:210.51.162.245: 3 Time(s)
Refused incoming connections:
   ::ffff:203.197.246.56 (::ffff:203.197.246.56): 4 Time(s)
   ::ffff:206.225.91.39 (::ffff:206.225.91.39): 4 Time(s)

bruteforce attack
I noticed today some brute force attacks on my server.. hmm interesting..
too bad I can't work on it full time so I did a quick add to the iptables firewall to drop all packets from that network. hehehe I hope we dun have users from italy and china then.
