[scponly] Environment variables

[Ryan J Ollos]

I'm sure this has been posted before, but I'm not having much luck searching
the archives.
 
I have compiled scponly as follows:
 
> ./configure --disable-gftp-compat --enable-sftp-logging-compat
--enable-passwd-compat
> make
> make install
 
Then I set the debugging level to 2.  The log messages are below, and I have
only edited them to remove the username and IP address, replacing these with
XXXXXXX.

May 22 20:32:13 XXXXXXX sshd[9065]: Accepted password for XXXXXXX from
::ffff:XXX.XXX.XXX.XXX port 2936 ssh2

the environment
May 22 20:32:13 XXXXXXX scponly[9068]: Unable to find "SFTP_LOG_LEVEL" in
the environment
May 22 20:32:13 XXXXXXX scponly[9068]: Unable to find "SFTP_LOG_FACILITY" in
the environment
May 22 20:32:13 XXXXXXX scponly[9068]: Environment contains "USER=XXXXXXX"
May 22 20:32:13 XXXXXXX scponly[9068]: running:
/usr/libexec/openssh/sftp-server (username: XXXXXXX (102), IP/port:
::ffff:XXX.XXX.XXX.XXX 2936 22)

 My question is ... how do I set the environment variables: SFTP_UMASK,
SFTP_PERMIT_CHMOD, SFTP_PERMIT_CHOWN, SFTP_LOG_LEVEL, and SFTP_LOG_FACILITY?

According to what I have read online, it appears that the only way to set
these is to recompile OpenSSH after applying a patch ... but I'm not even
sure how to set the variables after doing that.

Thanks!
