I've configured gnome-file-share-properties on all my Ubuntu's PC for sharing the directory Public to each other. I following some guide found on Internet for the configuration of it, all explain the same procedure but in my case I don't see any Public directory shared with the PC. Following this link
I'd see the directory Public plus the name of PC that shares its directory on Nautilus Places.
In my case I don't see anything, therefore on the Network place see all the machines 'n if I try to click on one receive this:
"DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)"
note: I don't want to use Samba because I've all Ubuntu PC, and the firewall is disabled on all PC.
