sshfs is an easy way to provide file access to a remote system with ssh. On Ubuntu, all you need to install it (on the remote client, nothing to do on the server if it already runs ssh) is run:
sudo apt-get install sshfs
To make things easier, you can make an /etc/fstab entry with the settings to mount a remote directory:
sshfs#chip@example.unicom.com:/home/chip /home/chip/Remote-Home fuse umask=0,defaults,noauto,user 0 0
Now, to mount the directory I just type (from my home directory):
$ mount Remote-Home
The problem is that if I try to unmount the directory it fails:
$ umount Remote-Home
umount: /home/chip/Remote-Home mount disagrees with the fstab
The command you have to use is:
$ fusermount -u Remote-Home
But you can make umount work with two simple steps.
First (this is the trick), run:
$ sudo ln -s mount.fuse mount.fuse.sshfs
