[KLUG Members] FW: sshd_config

I've done it many times without a problem.  Are you sure it restarted  
correctly?  Check 'ps' to make sure.

Also, (dumb question) you did uncomment the line when you change the  
port?  :-)

And run 'netstat -apen' to display the process that is listening on  
port 22 to be sure.
