Installed Openssl and ssh and have setup public key authentication.
Looking to automate an inbound file transfer using SFTP. Everything
is working fine, however, I need to lock the user down to a specific
directory, basically a restricted user account, or virtual root.

Does SCP/SFTP use ftp where I could setup anonymous ftp maybe. I
tried a restricted shell, but that broke the public key authentication
and this needs to be an automated process.

Basically the other vendor needs to send a daily file, and I want to
make sure they can't run around on the system from the SFTP shell as
some directory permissions are open.

Currently running AIX 5.2 with openssl 0.9.6m and openssh3.6.1p2_52
with all the native AIX utilities such as FTP. Can the equivalent of
virtural root be setup for sftp or do I need to load a third party ftp
utility or something to accomplish what I'd like.

Thanks for your input,
Ron

Thanks for the responses. Once I test the suggestions I'll report my
finding and setup info. Will be a week before I can test in the lab.
