Combing through the logs I also note huge numbers of brute-force
ssh password attempts (literally tens of thousands). So I was
pretty happy to find out about the AllowUsers and AllowGroups
keywords in /etc/ssh/sshd_config -- now there is only one username
that can log in.
It seems simpler than the denyhost package which scans the logs and
puts the offending IPs in /etc/hosts.deny.
