Running it in the background is not the same as running it as a service, as you have noticed. Also, since you have been running it directly from the command-line, you have now set ownership and permissions on various files and directories the SSH server uses. These are now tuned for the user you ran it as. This means three things: 1. You won't be able to run the SSH server as a service under any other user without resetting all these files/directories. 2. Since 'ssh-host-config' is set up to create a service for the SSH server using the SYSTEM or sshd-server user, you may find that running this configuration script no longer gets you a working SSH server service (see 1). 3. While it is possible and permissible to run the SSH server as a service under any user, you loose the ability to login with public key authentication as any user other than the one the service is running under. Depending on how important this ability is and how willing you are to look through the archives for recipes on how to reset permissions and owners on these files and directories, you may find it preferable to just wipe Cygwin from your system and re-install. You can then use the supplied scripts to quickly and easily configure your SSH server the way you want. Again, the openssh readme that a number of people have pointed you to is good and important reading for you, as well as the Cygwin Users Guide. > I do know what the 'Run' menu is in Windows.

Or are you telling me > to run sshd from 'Run' menu? No, not at all. I was referring to '/usr/bin/run' which hides the console of console apps when run directly from the Windows Explorer, for example. 'cygrunsrv' is similar to 'service' under Linux. It allows you to start, stop, install, and remove services, among other things. 'ssh-host-config' uses it. -- Larry Hall http://www.rfk.com RFK Partners, Inc.
