Q: When I try to log in to the CVS repository with WinCVS or other CVS client, I see this message: "cvs [login aborted]: connect to localhost:2401 failed: Connection refused". Why?

A: The most likely reason is that stunnel has not been started before you attempted to log in with the CVS client. Stunnel forwards messages from the CVS client on your local machine to the CVS server on the SourceHosting.net machine. It needs to be running in order for the system to work. Double-click on the stunnel shortcut you created after reading https://secure.sourcehosting.net/setup.php or run
C:\Program Files\stunnel\runstun.bat to start stunnel.
