OpenSSH sftp doesn't log much (anything?) - Have a look at the sftp-logging patches for openssh - they'll give you what you (we all!) want... I can honestly say I've used it with success in a few locations. http://sftplogging.sourceforge.net/ Sample debug output (from the link): Apr 27 17:00:35 host sftp-server[2888]: client is not permitted to chown. Apr 27 17:00:35 host sftp-server[2888]: realpath . Apr 27 17:00:39 host sftp-server[2888]: opendir /u/mikem/ Apr 27 17:00:45 host sftp-server[2888]: realpath /u/mikem/temp Apr 27 17:00:53 host sftp-server[2888]: setting file creation mode to 0666 and umask to 22 Apr 27 17:00:53 host sftp-server[2888]: open /u/mikem/temp/somefile.file Apr 27 17:00:53 host sftp-server[2888]: writing 32768 bytes to file Apr 27 17:01:00 host last message repeated 873 times Apr 27 17:01:00 host sftp-server[2888]: writing 9882 bytes to file Apr 27 17:01:07 host sftp-server[2888]: sftp-server finished. -- cheers brian
