Hi,
One option is to change the port that ssh uses. This can be done
by editing /etc/ssh_config. You can change it from 22 to something
like 3022. Be sure to account for the port change in you firewall.
That should drastically cut down on bandwidth waste.
HTH,

Hi,
I am running a Mac OS X Tiger Server and I am increasingly
observing attacks trying to log in via SSH and guessing user ids
and passwords. The server is only accessible via SSH from the
Internet and only two user ids whose passwords are well chosen can
log in via SSH. Nevertheless, I would like to limit those attacks
since they also consume quite some resources, esp. bandwidth. What
are you practicing or suggesting? I am using the firewall which is
included with Mac OS X.
Best regards

P.S.: Is there any literature/links on how to improve the security
of a Mac OS X Server?
