[scponly] sftp-server "No such file or directory"

[Dean Montgomery]

I'm running debian etch on a vserver and I'm unable to get scponlyc working.  
The non-chroot scponly works fine.


When I follow the FAQ page I get 
strace -o sftp.log -f -ff -p 2126
grep "^exec" sftp.log*
sftp.log.2193:execve("/usr/sbin/scponlyc", 
["scponlyc", "-c", "/usr/lib/openssh/sftp-server"], [/* 9 vars */]) = 0
sftp.log.2193:execve("/usr/lib/sftp-server", ["/usr/lib/sftp-server"], [/* 2 
vars */]) = -1 ENOENT (No such file or directory)

if you want I'll send a full copy of sftp.log.2193.

In /var/log/auth.log I see:
