SLAX as a wireless client & bridge for wired network


hello.

I have a linux BOX running BackTrack 1.0 , with ethernet card and a wireless network card, i would like to use it to connect to an access point & use the eth0 to connect to my Desktop.
I think i am trying to ask if there is a way to Run my linux machine as a linksys WAP 54 g or WRT 45G they both can be setup as wireless repeaters or clients or bridges.

First off, it is frowned upon to bump your own thread within 24 hours. We are a worldwide community here, so some folks have been at work/school/asleep while your post has been waiting.

Your question is also not very clear. What are you looking to do? Do you have both a computer and an access point, or are you looking to turn a computer with both wired/wireless cards into a router/access point?

The title of the tread seems to indicate you want to put this device between your computer and the access point, so the device receives the wireless signal from the access point, and delivers it to your desktop through the wired card?

The first technical thing to look at is why bother? You can get a wireless network card for very little money. If you are in the US, go to http://pricewatch.com and search for wireless G network card. Also check the HCL here are linuxquestions so you know the card will work. You can get them for around $20. If you're not in the US you still probably have access to cheap cards, at least cheaper than an unnecessary piece of equipment to connect.

It is possible to set up WAP54G linksys APs (older versions) as linux based units, but the recent version 5 cannot work, as they shrunk the memory by half. Still, that device is twice the cost of just a wireless card.

You can build linux routers out of PCs, I did that with my very first box. I would expect it would be possible ot make a bridge, but that might get more complicated. All you need for the router are the dhcpd program, some forwarding on the network card, and firewall rules to keep things safe. Not sure how the bridge would go. Probably something similiar, but I'm unsure.

Peace,
JimBass

Thank you for replying, 1st of all.

the issue at hand here is like i clearly stated in my 1st post and i quote
" have a linux BOX running BackTrack 1.0 , with ethernet card and a wireless network card, i would like to use it to connect to an access point & use the eth0 to connect to my Desktop"

in other words, i need this linux box to act as a wireless to wired bridge ( that can be achieved by making the box act as a wireless client and route the traffic to the eth0)

I found posts where people routed the traffic from wired and setup the linux box as an access point, what i need is to route from wireless to wired, the box will not be an access point but a client.

I know we can install linux on WRT and some other access points, my question is can I install the WRT linux to a PC running linux ?

Yes, I read your post, and it continued to confuse me. You mention a desktop, which I assumed was the linux box. Now that you spelled out that you want to use the linux box just to pass a wireless connection a wired, it is very easy to do.

Google or the tutorials here have articles on setting up a linux router. You should do that, using the wireless card on the linux box as the external device, and the wired as the internal. You don't need to run a DNS server on the linux box however. All you need is to enable dhcp, and forward the DNS server(s) to the wired machine. You'll need to have IP forwarding enabled on the linux machine.

From the quick google I did, WRT is just the firmware necessary to run linux on a linksys ap. It shouldn't be necessary or at all useful on a actual PC.

Again, what you are proposing to do here is akin to using a fire extingusher to put out a match, but if you have the time to do it, go right ahead. Get more fimiliar with google and the search feature here, as all of this has been asked many times before, and is well documented.

Peace,
JimBass

JimBass. Thank you for replying, Again.

I appreciate your input, if I wanted to use a router, and i have 2 of those, i would not have posted this question here....

WRT has a user interface that i want to duplicate on a linux machine, it is like having that wireless router + the storage space,

I'll wait for any other remarkes rather than searching google, which I did, and on the forum, again, there are posts where people explain routing from a wired network to wireless, i could not find a post that answeres my question, cause if there was, i would not be here.
