I've already got a female to worry about. Her name is the Enterprise.

I was with my geekfriends at a ski resort and I managed to get an Internet connection using a cellphone. Of course I wanted to share it with my friends. As geeks we brought a switch and a couple of ethernetcables.



Using this script on a Ubuntu 9.10 I managed to share my connection:

sudo ifconfig eth0
sudo sysctl -w net.ipv4.ip_forward=1
sudo sysctl -w net.ipv4.conf.default.forwarding=1
sudo sysctl -w net.ipv4.conf.all.forwarding=1
sudo iptables -P FORWARD ACCEPT
sudo iptables --table nat -A POSTROUTING -o ppp0 -j MASQUERADE

Conmnect everymachine with the switch and the clients just needed to use a network adress and add as default gateway and it works!
