I have installed Ubuntu 11.04 on 2 of my desktops PC's. I have not installed any addon packages or anything related to network. Please guide my on how to set up a LAN between these two machines. is there any GUI program to do this instead of Terminal? Because I am completely new to linux and am not very familiar with Terminal usage. I have the ethernet cable connected to a router which inturn is connected to my DSL modem to provide internet access to both my pc's.
