hi. I'm getting some alerts in my log files, and i getting worry.
The logs are some like this:
...
Apr 8 01:08:37 zeus sshd[9972]: warning: /etc/hosts.deny, line 15:
can't verify hostname: gethostbyname(ip.domain.pt) failed
Apr 8 01:08:37 zeus sshd[9972]: refused connect from 212.113.170.192
Apr 8 01:09:06 zeus sshd[1600]: warning: /etc/hosts.deny, line 15:
can't verify hostname: gethostbyname(ip.domain.pt) failed
Apr 8 01:09:06 zeus sshd[1600]: refused connect from 212.113.170.192
well, what this attack (i think that i can call it that), it's trying to
do?
Thanks in advantage,
Ricardo
