As far as I recall your speculation is indeed correct: a TYPE command is only necessary before a transfer (it's only used to transform data passing over the secondary data connection). I'm reasonably certain you don't need *anything* before a SITE command (like SITE CHMOD), not even PORT or PASV (unless the specific SITE command being invoked requires a data transfer, which CHMOD shouldn't). But as Steve suggests, the best way to know for sure is to give it a whirl and see what happens :-) Incidentally, you might like to experiment with the command line ftp client. On both Linux and Windows, the "quote" command can be used to send commands "raw" to the FTP server. For example: ftp> quote SITE CHMOD 755 afile.py Dave. -- -- http://mail.python.org/mailman/listinfo/python-list
