I have 2 laptops plugged into a ZTE ZXA10-F660 PON (like a 4 port ethernet router but with a fiber optic WAN connection). One laptop is running Linux Mint 19 Cinnamon (enp4s0) and the other is running Linux Mint 18.3 Cinnamon (eno1).

I've been using a portable external hard drive or a USB flash pen drive to transfer files between the two laptops for years because I find connecting two PCs via a LAN to be far beyond merely impossible.
I stumbled across LAN-Share (https://github.com/abdularis/LAN-Share) and fantasized that it would let me transfer files between the two laptops by going through my PON. Neither laptop can see the other on my LAN when both are running LAN-Share. There is a PON LED glowing for each ethernet connector plugged into a PON LAN port. Both laptops connect to the WWW with no problems and always have been able to do so, even when both were online at the same time.
A few magazine articles said LAN-share was really easy to use but the authors of the articles never met me. I installed samba on both laptops even though I don't know if I need it. I don't know what I do need. I don't know if what I want to do is even possible.
Is it possible to do what I want I to do?
