Wlan + Lan Bridge?

fabrizio432 · Apr 23, 2013

Is it possible setting vuplus to bridge wlan between lan, so the wireless network is on the same as lan network?

At the moment I can enable only one network at a time:

Hi,

i don't know if it's possible to setup bridge via menu, but you can try it via command line.

Here is how to do this

Maybe you can suggest to me where to find a bridge-utils.ipk for enigma2?

komodo · Apr 24, 2013

I have latest BH 2 and brctl is already there.

root@vusolo2:~# brctl --version
bridge-utils, 1.2

Uhm... via GUI I think it's impossible to do that you request.
You can use the wireless dongle on your box to act as Access Point using the corresponding plugin called "Wireless Access Point" into Plugin menu BUT I'm pretty sure that you don't have WLAN and LAN in the same network.

I use BH 1.7.9 at the moment, because I'm still waiting for a solution about the issues that affect media player in BH 2.
I'll see later if Bridge-utils it's available in my version.
Thank you.

fabrizio432 · Apr 24, 2013

Bridge-utils is available in bh 1.7.9 also.

I'm not sure how to proceed.

If I type these commands, I can't connect to vusolo anymore:

Code:

addbr br0
addif br0 eth0 ra0
ifconfig br0 192.168.1.97 netmask 255.255.255.0 up

fabrizio432 · Apr 24, 2013

I used this script:

Code:

#!/bin/bash
brctl addbr mybridge
brctl addif mybridge eth0 ra0
ifconfig eth0 0.0.0.0
ifconfig ra0 0.0.0.0
ifconfig mybridge 192.168.1.97 netmask 255.255.255.0 up

but it won't work

komodo · Apr 25, 2013

What exactly does not work ?

I don't have two interfaces, because i don't have wlan, but i tested with one and it's working.

Code:

#!/bin/bash
 
brctl addbr mybridge
brctl addif mybridge eth0
ifconfig eth0 0.0.0.0
ifconfig mybridge 192.168.2.200 netmask 255.255.255.0 up

and ifconfig output looks like this

Code:

When I launch the script, it returns:

Code:

add bridge failed: invalid argument

komodo · Apr 27, 2013

Maybe there is some bug in the bridge-utils or in the kernel.
Try it with new BH2 ane you will see if the problem is in the image or somewhere else.

Same message with BH 2.0.2.

komodo · Apr 27, 2013

Strange.

Could you please post output of ifconfig and script that you have ?

This is the script:

Code:

#!/bin/bash
brctl addbr mybridge
brctl addif mybridge eth0 wlan0
ifconfig eth0 0.0.0.0
ifconfig wlan0 0.0.0.0
ifconfig mybridge 192.168.1.99 netmask 255.255.255.0 up

This is ifconfig result:

As i say, i have not wlan iface, so i am not able to try exactly what you do.

What is dmesg last 10 rows, and lsmod output after you run this script ?

For me it's

dmesg

Code:

device eth0 entered promiscuous mode
mybridge: port 1(eth0) entered forwarding state
mybridge: port 1(eth0) entered forwarding state
mybridge: no IPv6 routers present

and you can see that bridge kernel module is loaded after this

lsmod

Code:

Module                  Size  Used by    Tainted: P
bridge                69070  0
stp                    1568  1 bridge
llc                    3729  2 bridge,stp

Maybe i can borrow some usb wifi at work and try it, but i don't know if there is some.

fabrizio432 · Apr 27, 2013

Maybe I do some error on launching script.
Telnetting "brctl addbr mybridge" it works
And also works "brctl addif mybridge eth0" and "ifconfig eth0 0,0,0,0", as you can see:

Of course as soon as I send "brctl addif mybridge wlan0" I loose connection.

To launch script I FTP "bridge.sh" in /tmp and then I send these commands:

Code:

cd /tmp
sh bridge.sh

What's wrong?

komodo · Apr 27, 2013

So if you run this script you have error, but from command line and brctl there is no error ?

Do you run script via telnet ?

Yes I do. I also runned via ssh with same result.

komodo · Apr 27, 2013

Ok, what error ?

If you run script you have error add bridge failed: invalid argument, but from command line it's ok ?

Btw, you loose connection because your IP is changed, so better way is to resolve problem with your script, because via command line you are not able to do all this without loosing connection.

komodo · Apr 27, 2013

Just one thing, do you edit this script via windows or linux ? There can be problem with EOL.
