SSHFS

by strikeforce — last modified Mar 10, 2008 12:52 PM

The idea of sshfs was taken from the SSHFS filesystem distributed with LUFS, which I found very useful. There were some limitations of that codebase, so I rewrote it. Features of this implementation are: * Based on FUSE (the best userspace filesystem framework for linux ;-) * Multithreading: more than one request can be on it's way to the server * Allowing large reads (max 64k) * Caching directory contents This install will explain how to install and mount sshfs. It will give examples of how to mount on boot using the /etc/fstab

Applicable to Fedora Versions

Fedora Core 7+

Requirements

You must have Fedora Extra's as a repository
You must have a ssh server to test this on

Doing the Work

You will need to install sshfs:

su -c 'yum install fuse-sshfs'

The user needs to be added to group fuse:

su -c 'gpasswd -a yourusername fuse'

How to mount it (Remeber to change it to your specific settings):

sshfs [email protected]: yourmountpoint/

To unmount:

fusermount -u yourmountpoint/

The next bits are your choice and are not required for SSHFS to function

We will set it up so that it automatically mounts on boot using fstab:

su -c 'gedit /etc/fstab'

You will need to add this line:

sshfs#[email protected]:/home/myname    /mnt/sshfs/homebox    fuse    comment=sshfs,noauto,users,exec,uid=1000,gid=1000,allow_other,reconnect,transform_symlinks,BatchMode=yes

Troubleshooting

How to test

If you get a fusermount denied error you may need to set sshfs to SUID:

su -c 'chmod u+s /usr/bin/sshfs'

You may get issues with SELinux you can either disable it or set it to permissive:

su -c 'gedit /etc/selinux/config'

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#       enforcing - SELinux security policy is enforced.
#       permissive - SELinux prints warnings instead of enforcing.
#       disabled - SELinux is fully disabled.
SELINUX=permissive
# SELINUXTYPE= type of policy in use. Possible values are:
#       targeted - Only targeted network daemons are protected.
#       strict - Full SELinux protection.
SELINUXTYPE=targeted


# SETLOCALDEFS= Check local definition changes
SETLOCALDEFS=0

We test this stuff on our own machines, really we do. But you may run into problems, if you do, come to #fedora on irc.freenode.net
