First, you need to set a flag in the 'debuglevel' file:

echo "1" > $SCPONLY_INSTALL_PREFIX/etc/scponly/debuglevel

Once that's set, you should get syslog output when you try to connect
to the sftp server.  It will look something like the following:

scponly[21249]: chrooted binary in place, will chroot()
scponly[21249]: 3 arguments in total.
scponly[21249]:   arg 0 is 'scponlyc'
scponly[21249]:   arg 1 is '-c'
scponly[21249]:   arg 2 is '/usr/lib64/misc/sftp-server'
scponly[21249]: opened log at LOG_AUTHPRIV, opts 0x00000009
scponly[21249]: determined USER is "kalebp" from environment
scponly[21249]: retrieved home directory of "/home/scponly//pub" for
user "scponly"
scponly[21249]: Setting homedir to /pub
scponly[21249]: chrooting to dir: "/home/scponly"
scponly[21249]: chdiring to dir: "/pub"
scponly[21249]: setting uid to 107
scponly[21249]: winscp_compat mode, argc=3
scponly[21249]: processing request: "/usr/lib64/misc/sftp-server"
scponly[21249]: Using getopt processing for cmd /usr/lib/misc/sftp-server
(username: kalebp(107), IP/port: 127.0.0.1 37088 22)
scponly[21249]: running: /usr/lib/misc/sftp-server (username:
kalebp(107), IP/port: 127.0.0.1 37088 22)
scponly[21249]: about to exec "/usr/lib/misc/sftp-server" (username:
kalebp(107), IP/port: 127.0.0.1 37088 22)

If you get something similar to the above but see a "Connection
closed" message on your terminal, than the sftp-server is being run
correctly but is missing dependencies or something else that's causing
it to run.  The FAQ page contains some details on how to hunt these
down using strace.
