Hi
To share internet using Win98, you need to have a gateway program like: wingate. Go to
www.tucows.com, you can find a shareware version there.
To share network files on win98 you need to set File and Printer Sharing utility installed in the network option.
To share network file on Unix, you need to set up Samba.
You also have to set up the workgroup and IP address of the 2 machines correctly so they can see eachother.
On Unix, you can use mount to connect to a network drive. Do a man page on mount.
This are the information so you can get a start. Let me know if you need more info.
Hope this would help
