    I was interested to learn of this port and we tried it this morning.; but we can't make it work.

    Setting debug level 2 in /usr/local/etc/scponly/debuglevel we get denied:

     ** ericx@king1 ** ~ ** Thu Aug 21 10:40:55
    $ scp bdrtest@k2:/usr/local/customers/customers.king2/bdrtest/personal/foo.txt .
    bdrtest@king2.vineyard.net's password:
    [48256]: 3 arguments in total.
    [48256]: arg 0 is scponly
    [48256]: arg 1 is -c
    [48256]: arg 2 is scp -f /usr/local/customers/customers.king2/bdrtest/personal/foo.txt
    [48256]: opened log at LOG_AUTHPRIV, opts 0x00000029
    [48256]: retrieved home directory of "/usr/local/customers/customers.king2/./bdrtest" for user "bdrtest"

    [48256]: processing request: "scp -f /usr/local/customers/customers.king2/bdrtest/personal/foo.txt"

    Apparantly this question has been asked on the scponly mailing list; but never answered.
