Now you've got me kind of curious about the unofficial ssh "hacks" you mentioned. ;-) It would be sweet if "we" could just simply set the users shell to usr/bin/false to prevent ssh while still allowing scp/sftp. I've got a hunch doing this involves non-trival code changes. JCR -- A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting.
