[scponly] sftp works scp does not

[Pawel Mueller]

Hi Folks,

I found it out. It was the option
--enable-sftp-logging-compat

after I found out, that I can set the debuglevel variable in
../etc/scponly/debuglevel I saw that:

Feb 10 18:33:15 zsdweb1 scponly[31203]: processing request: "pwd"
Feb 10 18:33:15 zsdweb1 scponly[31203]: Unable to find "LOG_SFTP" in the
environment
Feb 10 18:33:15 zsdweb1 scponly[31203]: Found "USER" and setting it to
"scponlytest"
Feb 10 18:33:15 zsdweb1 scponly[31203]: Unable to find "SFTP_UMASK" in
the environment
Feb 10 18:33:15 zsdweb1 scponly[31203]: Unable to find
"SFTP_PERMIT_CHMOD" in the environment
Feb 10 18:33:15 zsdweb1 scponly[31203]: Unable to find
"SFTP_PERMIT_CHOWN" in the environment
Feb 10 18:33:15 zsdweb1 scponly[31203]: Unable to find "SFTP_LOG_LEVEL"
in the environment
Feb 10 18:33:15 zsdweb1 scponly[31203]: Unable to find
"SFTP_LOG_FACILITY" in the environment
Feb 10 18:33:15 zsdweb1 scponly[31203]: running: /bin/pwd (username:
scponlytest(1004), IP/port: 129.69.3.249 4873 22)

so I just disabled sftp-loggin-compat and users can login without
problems. Strange that... can anybody explain please.
What exactly it sftp-logging? And how I can enable it anyway?

thx a lot
Pawel
