[scponly] scponlyc + successfully connecting but immediate disconnect

[ScottO]

Hoping someone can help here.  SSH'ing in with public key, public key is 
accepted and then I am immediately dropped out of my session with the 
following debug output after doing: echo 2 > 
/usr/local/etc/scponly/debuglevel.  Really not sure how to make sense of 
this debug output or where to go next based on it.  Dug through the 
mailing list and googling hasn't turned up a solution yet for me.  Any 
help or pointers would be much appreciated.  Thanks!
