Introduction

Its often requested of me to clearly detail various feature of my firmwares. Well this is the first tip in a series I’ll try and add to occasionally. The first tip deals with a feature that I have just included in WDLXTV-LIVE, which allows you to mount NFS shares under the ‘Network Shares’ category–which means you don’t have to have any local storage connected to view 1080p goodness off your NFS!! :D

This is a momentous occasion and a great feature that I am happy to finally be able to offer.

Now this trick requires a bit of a workaround. Heres how it works in a nutshell:

• You create on your NFS a samba/cifs share; any location, any password, any username
• The WD TV Live detects the CIFS share and shows it under ‘Network Shares’
• You click on the entry and enter ok for the login info (if auto-login is not enabled)
• I intercept the login and parse a file for shares to mount instead
• You are then displayed your NFS shares!!!

Setup

Ok, so now full details and a walk through.

Step 1

Set up a CIFS/Samba share on your NFS device. The share can be anything really, all its used for is a placeholder so that our desired shares can be mounted.

Step 2

Verify that the CIFS/Samba share you set up is being detected by the WD TV Live. If it is detected, move on to step 3, otherwise go back to step 1 get it set up correctly.

Step 3

SSH into your WD TV Live and execute the following:

config_tool -c CIFSINTERCEPTOR=ON

This turns the cifs-interceptor on.

Step 4

Now for the config file, which is a text file (with no extension) called: cifs-interceptor

cifs-interceptor is of the following format:

//cifs-server/share-name|NFS01 NFS01-label|NFS02 NFS02-label|...|

cifs-server is the ip of the server where you set up the share in step 1. share-name is the name of the exposed share you set up in step 1.
NFS01 is the full address of the first NFS
NFS01-label is what you’d like the NFS01 to be mounted as
NFS02 is the full address of the second NFS
NFS02-label is what you’d like the NFS02 to be mounted as
continue on for as many NFS as you desire to be mounted.

Here is my example /conf/cifs-interceptor

//192.168.0.104/b-rad|192.168.0.104:/media/disk slug|

This says that the share I’ll be intercepting is //192.168.0.104/b-rad and instead of mounting it I’ll be mounting 192.168.0.104:/media/disk as slug. Now note I could easily have had multiple more NFS’s listed, each must just be seperated by a pipe ‘|’.

Note the ending pipe, it is very important. Be sure to end each cifs-interceptor line with one.

cifs-interceptor needs to be uploaded by /conf, so either edit it via telnet/SSH OR ftp in and upload it directory to /conf.

When you have /conf/cifs-interceptor in place you’re ready to go.

Step 5

With CIFSINTERCEPTOR=ON and /conf/cifs-interceptor configured we can go and select the server from step 1 and *hopefully* our desired NFS shares show up instead.

NOTE:
This will ONLY intercept shares you have listed in /conf/cifs-interceptor, if its not listed in that file it will be mounted like normal. This means you can have normal CIFS/Samba shares mounted, and then a special one which will be intercepted and used to mount your selected shares under.

TIP:
I don’t like having to select ok every time when it asks me for username & password … since that information is irrelevant and I’d prefer it autolog me in. So to turn autologin on, telnet/SSH in and execute the following:

   config_tool -c ENABLE_AUTO_LOGIN='1'

With that set any time you select the server it will automagically mount and display your NFS shares :D

TIP 2:
The shares we are mounting instead of the intercepted CIFS do not necessarily have to be NFS, they could just as easily be CIFS or anything else.
