[ubuntu-uk] networking two pcs- Ubuntu and xubuntu

[STONE COLD]

Hi ,

I was wondering if someone could help.

Ive connected my pc running ubuntu (main pc) with a pc running xubuntu (secondary pc). They are connected via one of those linkys ethernet routers! ive managed to get the internet working on the secondary pc but im unable to see any folders or anything else on this pc. Im using a cable to connect both pc's! 

Ideally i want my main pc to see the secondary pc and be able to save stuff on it! ive looked at the network tools but really didnt get anywhere with that!

Any ideas please?
