Step one: open the PCLinuxOS Control Center
Step two: click on "network sharing"
Step three: walk through "share drive using NFS" - if you're asked to download and install software, do so. make sure the server starts
Step four: go to another computer on your network, do steps one and two, but instead of step three, click on "Access NFS shared drives and directories". You should see the server you set up on the first PC, but if you don't, click "search servers".
Step five: when you see the server, walk through the setup using the defaults. At the very end, click the "Mount" button on the bottom. When you click "Done", a dialog will ask if you want to write to fstab - say yes, and then you'll always be able to find the share under /mnt/yourshare. I drag it from the directory to my /Desktop and choose "link here" for easy availability.
You may have to logout/login, and sometimes a reboot works better for me.
