Wireshark (nee Ethereal) will show the DNS traffic if this is the case. Typically the client wants to display the server's name where it can, instead of its IP address. The simplest way to address this is to put a server entry in the client's /etc/hosts (or Windows equivalent). More generally, perhaps something like the following might work: # echo 'UseDNS no' >> /etc/ssh/sshd_config # /etc/init.d/sshd restart Hope this helps. regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 Holden Web LLC/Ltd http://www.holdenweb.com Skype: holdenweb http://del.icio.us/steve.holden Sorry, the dog ate my .sigline -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
