Internet Sharing

I am new to linux and networking on linux. I was trying to set up an adhoc network between my laptop and another laptop (running windows7).
I handle the connections on the laptop with wicd.

So I went through
http://wiki.archlinux.org/index.php/Sim … l_firewall
http://wiki.archlinux.org/index.php/Iptables
http://wiki.archlinux.org/index.php/Internet_Share
http://wiki.archlinux.org/index.php/Sha … _interface
http://www.howtoforge.com/internet-conn … g-on-linux

To learn/find out how to achieve my purpose.

So I set up the iptables, set "net.ipv4.ip_forward=1" in "/etc/sysctl.conf" and set up a wireless connection in adhoc mode.
The client laptop can see the connection and can connect to it, but it has no network access.

Please advise. Thanks!

Re: Internet Sharing

How is the client laptop getting an ip address? Are you running dhcp on the other one, or setting a static ip?

Re: Internet Sharing

Well I assumed that windows would handle obtaining the ip address automatically with default settings. But since it did not work, I manually changed setting for the wireless card with:
Gateway: 192.168.0.254
IP: 192.168.0.2
Netmask: 255.255.255.0
DNS: 8.8.8.8 (google dns)

on the host I added the following to etc/dnsmasq.conf

domain-needed
bogus-priv
interface=wlan0
dhcp-range=192.168.0.1,192.168.0.100,12h

and I assigned the ip to my wireless card as follows:

ifconfig wlan0 192.168.0.254 netmask 255.255.255.0

Re: Internet Sharing

Did you try followinig the Internet Share archwiki article step by step (adapting 'client'-side to windows of course)?

I regularly use what was being explained there succcessfully to let my netbook be a gateway for another computer. (Witthout dnsmasq/other dhcp-server.)

Re: Internet Sharing

Yeah, actually I had initially followed that wiki!  When it didn't work out, I looked at the Sharing ppp connection with wlan interface Wiki and borrowed the bit about the dnsmasq.

Though the dnsmasq bit shouldn't change anything dramatically I believe. (or would it?)
