share internet with a Slack or Arch linux

Well, my problem is this:

I have my laptop, getting internet via wifi in my home, and i have it connected via crossover cable wit a old PIII that has Slack 13.1 installed on it. I use wicd (so dhcpcd) to connect in my wlan0 device (i don't know if this is relevant)

I am thinking on installing Arch on the old computer (no, i DON'T want to compile a full gentoo system with 455 mhz), or in case of saving Slack, at least update some programs i need, without moving physically the computer to a router.

I tried with ifconfig, assigning a static ip on both of them, a mask, and broadcast. I tried the same as it has the laptop (with internet working) too. I tried in the laptop also to assign the same values for eth0 that wlan0, in a hope that would bridge the wifi card with the lan card. No results (at least i can ssh the 2 computers).I don't know what more to do. I searched google, but what i found is how to do it with the connection manager of puppy or ubuntu, but i am not using anything more than my terminals (i want to learn how it works and how to do it!). I am not using iptables, so at least i don't have to create firewall rules.

Anyone can help me? Is not urgent, but i really want to know how it work, and how to do it. Thanks in advance :wink:

vladimir1986,

There are two ways to do this. Set up your laptop as a router, follow the Gentoo Home Router Guide
This is written as if you set up a deicated PC as a router but you can add it to your laptop.

This is well documented, just works, and allows you to connect a large number of machines to the internet via your laptop.

The alternative is to use PPP on the link between your laptop and Slack install. Both kernels need PPP support and you need a script to set up PPP on the laptop. The downsides are,
a) needing to run the script to get the link up
b) at most one system can be on the end of a PPP link.

I have a script you can build on if you want to go this way. Its written to do PPP over USB but it should be easy to change.

I would love to try bot ways. The PPP way would work maybe for my first computer (Pentium I, with pcmcia dial-up modem), so if you post the script, that would be really nice. I have custom kernels in both computers, so i have the fearing part in the .configs done. As for day to day, i think i would use the handbook way. Seriously, i am stunned on how many documentation is aviable for Gentoo. Thanks for everything.

vladimir1986,

Here is the script,

Hello, and thanks for the reply.

I did all you tell, but have some doubts:

IPAQ_ADDR, IPAQ_NET... are the ip of the guest system?

And what i do on the guest after executing the script on the host?

As far from the handbook... i have to adapt a bit, as they are thinking of two net cards... i have only one, and the wifi card communicating with the router. I assume is not very different.

I cant do anything untill tomorrow anyway, so i will post the results tomorrow.

Thanks!
