Shfs is a simple and easy to use Linux kernel module which allows you to mount remote filesystems using a plain shell (ssh) connection. When using shfs, you can access all remote files just like the local ones, only the access is governed through the transport security of ssh.
Shfs supports some nice features:
- file cache for access speedup
- perl and shell code for the remote (server) side
- could preserve uid/gid (root connection)
- number of remote host platforms (Linux, Solaris, Cygwin, ...)
- arbitrary command used for connection (instead of ssh)
- persistent connection (reconnect after ssh dies)
If these features cannot convince you, I probably cannot either. Yet, consider: the only thing you need on the server is a sshd running - and you can mount your filesystem from anywhere in a secure way.
In order to use shfs it needs to be installed and configured on the client side, NOT on the server side! Server only needs to have working sshd running.
If you want to use shfsmount as mortal user, you will have to
chmod +s /usr/bin/shfsmount and
chmod + /usr/bin/shfsumount. However it is much more comfortable to put your mount options into
/etc/fstab - this is what mine looks like:
remoteuser@Server:/data /mnt/data shfs rw,noauto,uid=localuser,persistent 0 0 remoteuser@Server:/crap /mnt/crap shfs rw,noauto,uid=localuser,persistent 0 0 remoteuser@Server:/backup /mnt/backup shfs rw,noauto,uid=localuser,persistent 0 0 remoteuser@Server:/home /mnt/home shfs rw,noauto,uid=localuser,persistent 0 0
Soon you will get tired typing passwords and once you do, you might consider Using SSH Keys.
Btw, if you are a paranoid bastard, like I am, and do not run ssh on port 22 on your server, you will need to complete your option list with
To add an entry for an shfs volume in your fstab, add a line of the format:
userid@remoteMachine:/remoteDirectory /home/userid/remoteDirectory shfs rw,user,noauto 0 0
