Another option in addition to all the other good advice you've been sent is to use sshd via xinetd and you can restrict access to specific IP addresses/ranges, times of day, connection frequeceny and the other options listed in "man xinetd.conf". A typical configuration to limit access to the 192.168.1.0 network would look something like: service ssh { disable = no socket_type = stream type = UNLISTED port = 22 protocol = tcp wait = no user = root server = /usr/sbin/sshd server_args = -i -u0 only_from = 192.168.1.0 } Regards, Mike Klinke
