Thank you for your responses. Can you tell me how to check the TCP
wrappers?
Also, I am new to linux (been on SGIs for ten years). Can you tell me
how to
check to make sure the firewall is letting ssh traffic thru?
Many thanks,
Paula

Also, as others suggested, make sure firewall lets through ssh traffic.
