One of the things you might miss on a DD-WRT enabled router is its ability to write to storage. If you run a Linux samba or Windows server on your LAN, the Samba file system provides a convenient solution to customize this storage! It adds a vast amount of writable storage to your router and even offers an automatic startup script.

Instructions

  1. Create a SMB network share on the host computer.
    • On Linux, use Samba to create a SMB network share. HOWTO
    • On Windows, this is the default file sharing system. Simply right click and select "Sharing and Security" to set up sharing.
  2. Use the Web Interface and go to the Administration tab.
  3. Enable the Samba FS Automount option. If new options do not appear the "Save Changes" and go back to the page.
  4. Enter the share location in the 'share' field. eg: //192.168.1.160/myshare
  5. In 'user' and 'password' enter the user credentials of a user allowed to access the share.
  6. You may optionally enter a Startscript. For example if you have a script on your share \\lanserver\myshare\startup.sh you enter startup.sh in the 'Startscript' box. This script (/tmp/smbshare/startup.sh on the router) will be executed when the router mounts your share on boot.

You can see sample of startup script on Jffs page.

Mount Manually

You may want to manually mount a share. To do this, simply enter this command in a Telnet or SSH prompt:

  • /tmp/Path/ is the path you want it mounted
  • Don't forget that only /tmp/, /dev/ and potentially /jffs/ are writeable!
mkdir /tmp/Path/
smbmount //<IP.SE.RV.ER>/Share /tmp/Path/ -o username=<user>,password=<password_user>

Receiving errors like this seems normal:

 load_client_codepage: filename /usr/lib/codepages/codepage.850 does not exist.
 load_unicode_map: filename /usr/lib/codepages/unicode_map.850 does not exist.
 session request to 192.168.1.99 failed
 Can't get /etc/mtab~ lock filesmbmnt failed: 1

To unmount a share, enter this command in a shell prompt:

 umount /tmp/Path/
 rmdir /tmp/Path/

Note for Windows Server 2003

Especially on Windows Server 2003, assert that your server accepts NTLM v1.

  1. Goto Start > Run
  2. Type "gpedit.msc" and push enter.
  3. Goto Computer Configuration / Windows Settings / Security Settings / Local Policies / Security Options.
  4. Verify that "Network security: LAN Manager authentication level" is NOT "Send NTLMv2 response only\refuse LM & NTLM"

Install Samba Server on DD-WRT

If you have a powerfull Router like the Asus Asus WL-500gP(remium) you might want to use the USB 2.0 Ports for HD sharing with Windows Clients. At first install the USB stuff according to http://www.dd-wrt.com/wiki/index.php/USB#Installation


To install Samba just type:

ipkg install samba

after some package installing the samba server is ready.

Errors

Unfortunately /jffs/etc/init.d/samba start fails with

nmbd: can't resolve symbol 'fopen64'
smbd: can't resolve symbol 'stat64'

this can be solved with the uclibc_0.9.28-6_mipsel.ipk Package. A nice Howto for this is located here http://www.dd-wrt.com/wiki/index.php/Optware

You should really try it the optware way because it works :)

Ready

Now the Samba server is ready, only the config file (/jffs/etc/samba/smb.conf)needs some adaptation.
