SSH access to only users home folder

[bshosey]

I would like to set a user to only be able to be in their home directory. I have a user that sftp in to my ubuntu 8.04 server. I only want him to be able to see his home directory I dont even want this user to be able to navigate away from his /home/"USERNAME"/

I also use ssh and do not want to be restricted.

Is this possible?

You need sftp or ssh restriction? Your title doesn't match your post
I think you can restrict them using the chroot command

1) rssh + chroot: http://www.cyberciti.biz/tips/rhel-c...ssh-shell.html
2) modify your permissions, so that "others" can't see the files/folders.
Usually it's good to restrict the home folder, so that others can't see the other usernames.. as far as system files, I'm not sure.
3) I'm not sure, but you could read about bash -r / restrictive shell

4) Finally, you have chroot jail utilities
