How to connect 2 linux pc with a sharing connection
you should have 2 network interfaces:
– one directly connected to internet (i use ppp0 in this tutorial)
– and the other for the connection of the 2 pc (i use ethernet eth0)
on the pc connected to internet (the “server”):
sudo ifconfig eth0 192.168.100.1 up
sudo iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
sudo sh -c “echo 1 > /proc/sys/net/ipv4/ip_forward”
and then look at the resolv.conf file: gedit /etc/resolv.conf
on the other pc (“client”):
sudo ifconfig eth0 192.168.100.x (substitute x with a number from 2 to 255)
sudo route add default gw 192.168.100.1
then open the resolv.conf file and add here the address that you have find on the server pc.
enjoy your shared connection!!!
