[scponly] sftp not working, but scp does

[Paul Hyder]

Sounds like the selected sftp server exits.

Have you tried setting the debuglevel to 1?  (default install puts this
file in /usr/local/etc/scponly, change it from 0 to 1)  The extended
diagnostics should be useful.

Would also help to know what options you used with configure and the
server's operating system.
