DSL Tips and Tricks :: mount from remote system using fuse and sshfs



Here's a script to mount something from a remote system running an SSH server.  On your local machine you need a mountpoint, load the fuse module and mount using sshfs.
Code Sample

# script mounts a path from a remote system using fuse and sshfs

THISPROG=`basename $0`
PUBLICIP=12.34.56.78
LOCALIP=192.168.0.2
SSHPORT=22

USAGE="
Usage : $THISPROG [options] {username} {remote path to mount} {local mount point}

local mount point must be an existing directory

options :

-r {IP address} : use IP adress for remote host , e.g. -r 123.45.67.89
  Default remote IP is $PUBLICIP

-p {port number} : Port number to use for ssh connection , default $SSHPORT

-l {IP address | d} : remote host at local LAN , no caching.
  Use provided IP address or default (d) $LOCALIP

Unmount :
Code Sample
sudo fusermount -u $MPOINT


Enjoy

Sorry, follow_symlinks is not recognised by DSL as an sshfs option.

Correction to the script :
FSOPTIONS="-o compression=yes,transform_symlinks,allow_other,nonempty"
