I have a local server running Ubuntu 18.04.1 which was recently upgraded from Ubuntu 15 where I had a few shares configured manually via Samba in
[myshare] path = /home/user writeable = yes valid users = root, user
This has continued to work just fine since the upgrade but today I noticed if I right-click on a directory in Gnome I get a dialog window with a tab called "Local Network Share" that looks like this:
I enabled it and now it's showing up on my LAN as another share. My question is, where is this configured? Is it using Samba as well or some other service? I took a look at
smb.conf where the other shares are configured but its not there.
