can I jail ssh for more that one directory?

Question

I have working jail ssh to one directory.

I would love to give r/w access for the jail ssh user to few directories. For example

• /tmp/user
• /home/user
• /srv/www/user

is that possible?

Answer 1

You cannot symlink to anything that is not inside the chroot'ed environment.

I would suggest doing a mount --bind:

(assuming the user's chroot directory is /home/john

mount --bind /tmp/john /home/john/tmp/john
mount --bind /srv/www/john /home/john/srv/www/john

Answer 2

You can create the directories under /home/user, and then symlink them to the original places. The only problem I see is that the users /tmp will not have the /tmp's noexec.
