transfering files from PClinuxos to Kubuntu computer

[Eric]

I have two computers and I'd like to be able to transfer files between 
them. One is running PClinuxOs 2007 and the other is running Kubuntu 6.06.

Is there an easy way to network them together so that I can transfer 
files between them? Most of the time I would want to transfer from the 
PClinuxOs machine to the other.

Thanks for your help.
