logging details

Lars -      5.5 does not seem to be available, yet.  I am running OpenSSH_5.4p1.
Damien - The xferlog was from an ftp session.  I was just using it to show that ftp can tell me the file which was transferred.
               I moved the sftp log under the chroot /dev area.  It still logs everything, except the file name.

I understand that the filename and directory information will be coming across the network encrypted.  But, there must be a way the server can figure out what file was transferred.  It knows the PID of the connecting process.  Does the logfile need to be writable by the accounts doing the transfers?

- Sue

That burden seems to have been removed starting with OpenSSH 5.5, and the following does logging with the specified log level and faclity code without needing a socket in the chroot:

  ChrootDirectory /altroot/foo/
  Subsystem	sftp	internal-sftp -f LOCAL0 -l VERBOSE
  ForceCommand	internal-sftp
