Here’s a direct and nonstandard way, not filled with endless command-line entries:
Download and install a version of Mepis Linux. Put it on all your machines - even dual-boot if you like (I have several machines I do this with).
After you login, right-click on any partition you wish to share and select “properties” “file-sharing”. A small window will pop up asking if you want to run the “filesharing” program. Click yes and select your partition. It will now appear on all computers connected to your local network. Copy and share all you wish. :)
See? No command-lines to memorize and laboriously type out. Right-click and share, right-click again and un-share. Simple.
Oh, and don’t forget to select the Windows Share (Samba) option when you enable filesharing.
Later, as time goes by, you can work on figuring out how to get filesharing working on other OSs’ and what it will take to get them functional. Right now this will allow you to share things immediately.
Good Luck!
I'll give it a shot. I'm headed over to PIA to see if I can get it running on Mepis.
