sharing folders with passwords

Question

I have a Linux box which should share a few directories to other systems over the LAN. The other systems are running linux as well.

I'd like to associate a different password for each folder without creating different users. Is there a way to achieve that?

Feel free to put NFS and SSH combos into the mix. The key point is that I need different passwords for different directories, like this:

EXPORTED DIR: /opt/dir1 PASSWORD: 'foo'

EXPORTED DIR: /usr/lib/dir2 PASSWORD: 'bar'

Answer 1

If you simply want to password protect each folder then you'll have to use something like Samba. There is no other method of sharing a file system/directory I know of that'll allow you to put a (shared) password on a share.

Answer 2

If the folders are small in size perhaps encrypt each with a different password using gpg.
