[scponly] sftp works but scp doesn't... any idea ?

[Paul Hyder]

The groups problem sounds like you didn't install the binary
compiled from the scponly release.  (Which would mean that the
platform's existing groups command is a shell script.)  That true?
[I believe you aren't chrooted so using this binary is likely to
be a bit difficult, but scponly can't execute a shell script.]

Perhaps I missed it but it would be helpful to see the full
syslog traces, with debuglevel set to 1, for a Linux scp attempt.
(Including the scp command that was used.)
