TV=Network HUB for WIRELESS-ETH0?

[gchirtoaca]

Hi,

This may be an absurd question, but...I want to use the network connection of the TV, that is wirelessly connected to my router, so that my IPTV box, connected to the unused wired LAN port of TV, will be able to also get a connection to the router.
This is because I want to get rid of the cable that's now connecting the IPTV box to my router.
I'm a Linux beginer, but I guess there is a way to connect the wired LAN interface eth0 to the wireless interface ra11n0. I have access to the TV shell. I activated the eth0 interface using "ifconfig eth0 up" and gave it an IP address.

Thank you.

Actually I think we need to set up network client-bridge.

What is needed:

• busybox brctl applet
  It can be downloaded from here.
• bridge module support for kernel (recompiled kernel or separate module)
  I stuck on error:

  Code: Select all

  LD [M]  net/bridge/bridge.o
  /bin/sh: .tmp_versions/bridge.mod: No such file or directory
  make[1]: *** [net/bridge/bridge.o] Error 1
  make: *** [net/bridge/bridge.ko] Error 2

  After some researches i found possible solution:

  The solution:
  make -C /usr/src/redhat/BUILD/kernel-2.6.21/linux-2.6.21.i686/ SUBDIRS=net/bridge/ modules

  But it did not help:

  Code: Select all

  root@localhost:/usr/src/linux/linux-r011# make -C /usr/src/linux/linux-r011/ SUBDIRS=net/bridge/ modules
  make: Entering directory `/usr/src/linux/linux-r011'
  
    WARNING: Symbol version dump /usr/src/linux/linux-r011/Module.symvers

  make[1]: *** [__modpost] Error 127
  make: *** [modules] Error 2
  make: Leaving directory `/usr/src/linux/linux-r011'
  

  Another possible solution did not help as well.
• Some configuration to convert TV to wireless client (or repeater?)
  http://www.adamsinfo.com/brctl-creating ... rk-bridge/
  http://www.faqs.org/docs/Linux-HOWTO/BR ... -THE-UTILS
  https://help.ubuntu.com/community/Bridg ... Interfaces

The question is: what is wrong with my compiler? (i use native toolchain)

p.s. Finally i figured out - the missing *.mod file for module i get with this command:

Code: Select all

make -C /usr/src/linux/linux-r011/ SUBDIRS=net/bridge/ module
make -C /usr/src/linux/linux-r011/ SUBDIRS=fs/cifs/ modules

I do not know why i got this error earlier...
I still get same error after distclean for any module i want to compile and fix it with command above.

Now my cross-compiler runs (well? not sure yet - i still get a lot of warnings while kernel compilation and it ends with error...)

p.p.s. I installed CodeSourcery compiler for arm. I`ll write short how-to later.
Linux version grab here.

Don't know what went wrong juuso,

I just did
make menuconfig, switch on Ethernet bridging,
make -j3
and hey presto,
bridge.ko built within seconds. (not that I am going to use it)

kernel 2.6.18_SELP_ARM-something, cross-build toolchain from Samsung (gcc 4.2.0 etc)

probably your kernel configuration is missing some dependencies, as set in the configuration stage.
Mixing modules from different kernel version in general is not a good idea, unless you like backporting .

grtz,

[juusso]

thanks! i will try find out whats wrong, but... could i have compiled binary?

[marcelru]

on its way:

[juusso]

It seems, it won`t load:

Code: Select all

insmod /var/bridge.ko
insmod: cannot insert `/var/bridge.ko': Unknown symbol in module (-1): No such file or directory

[marcelru]

Hmm,

Looks like there's some extra built-in stuff to it:

So possibly you will need a kernel replacement for this to work ...

Hi,

It seems it's harder than I thought.
Thanks for the investigation anyway, guys.

[juusso]

I`m trying to compile whole kernel with bridge enabled. I`m not going to use bridged network on TV, but it is interesting to get it working.
Just for fun...

That would be great, thanks!
