Re: CYGWIN--SSHD on a port other than 22?

Thanks Stephen Herr, Stephen Casey and Rajneesh Hegde. :-D

My Router can not do port mapping from the router's port to a different
internal port at the PC, it's a 1 to 1 deal. I was able to edit the
etc/sshd_config file and set both of my sshd servers to run on a
different port than 22. I'm now able to log in fine with both Putty and
WinSCP (sftp gui program). Once on my local machine, I can also use the
following commands to get to the other local machines:

ssh -p 55002 userid@my.ip.address
sftp -oPort=55002 userid@my.ip.address

In this example, 55002 is the port my sshd is running on and you can
substitute the domain name for "my.ip.address" if you have one. It all
worked fine :-D

Greatly appreciate all of your help, thanks - Alan
