Sharing Internet Connection

[Maniaman]

Ok. I'm using Mandrake 9.0
I want to share the internet connection with a Windows XP system. I tried using Mandrake's Internet Connection Sharing, but the XP machine doesn't recognize the connection. I'm running Samba Server.  Any idea how to get it to work?


And - The XP machine is my dadsmachine. He won't let me put Linux on it

You could try to set up a proxy server, or even better you could set up mandrake as a router. ipchains will do this for you.

echo "1" > /proc/sys/net/ip_forward
ipchains -P forward DENY
ipchains -A forward -i eth0 -s 192.168.0.2 -d 0/0 -j MASQ

replace 192.168.0.2 with the IP address of the winxp machine. Also make sure you set your linux computer as the gateway in winxp.

I'm having problems with this ipchains thing.

[root@ip-addy-wuz-here root]# echo "1" > /proc/sys/net/ip_forward
bash: /proc/sys/net/ip_forward: No such file or directory


Now what do I need to do? Running Mandrake 9.0

On the newer kernels it's:

# echo 1 > /proc/sys/net/ipv4/ip_forward

Also on the newer kernels (2.4+) you would want to use iptables rather than ipchains. And you would normally put that command and all the firewall commands/rules in a script. Now Mandrake is supposed to have a graphical tool for configuring the "connection sharing" which is what you are doing here. A more common name for this is "IP Masquerading". Here is the HOWTO:
