[edit] Introduction

The purpose of this document is to explain how I finally succeded in mounting a samba folder from my Linux Server into my /jffs WRT54G folder. The idea is explained here but If you are a newbie in Linux [I am] you may find it difficult to reach.

My main problem was to obtain permission to write into the shared folder, so I will explain how I changed the file smb.conf as well as the full process.

  • Note: As I'm a newbie in Linux, someone should correct this wiki to improve security issues.

*Note: If you don't have a Linux server but a Windows server to do battle against the permission problem, you can create a EXT3 image file (the linux filesystem, permission friendly) to have on the windows machine or for example a nas drive with the FAT filesystem (that was my problem) and install a ext3 module and a loopback module on the WRT54G and then mount the file as /JFFS.

[edit] Instructions

Replace <....> text with your settings.

[edit] Linux SERVER

Create and user if you only have the root user:

[Debian / Ubuntu]:
#adduser <user> #passwd <user> enter <password_user>

Install samba if you don't have it:

[Debian / Ubuntu]:
#apt-get install samba smbfs

Edit config file /etc/samba/smb.conf (in my case it worked adding this at the end of the file):

     comment = JFFS mounting folder
     path = <your_jffs_path_in_the_server>               
     read only = No
     valid users = <user>
     invalid users = root bin daemon nobody named sys tty disk mem kmem users

You should finally restart your computer for the changes to take effect or stop/start the samba service:

#/etc/init.d/samba stop
#/etc/init.d/samba start

In <your_jffs_path_in_the_server> create the <script_file> with these commands inside:

umount /jffs/
smbmount //<IP.SE.RV.ER>/jffs /jffs -o username=<user>,password=<password_user>

  • Note: If <your_jffs_path_in_the_server> (mine is /media/data/jffs) is in a FAT32 partition, you should permit rw access to it within the /etc/fstab config file. This is how is mounted my FAT32 partition inside fstab (you should restart your computer if you change this file):
/dev/hda5       /media/data     vfat    users,umask=000        0       0

[edit] WRT54G Web Interface

Enable JFFS2 Support under Administration -> Management:

JFFS2 Configuration:
JFFS2 enabled: X Enable Disable Clean JFFS2: X Enable Disable

Enable Samba FS Automount under Administration -> Management:

SAMBA Configuration:
SMBFS enabled: X Enable Disable Share: //<IP.SE.RV.ER>/jffs User: <user> Password: <password_user> Startscript: <script_file>

Restart your WRT54G
