Not sure how you're scanning and from what. In this case the only thing sure is that Linux is the hostname assigned by your router which may or may not be allowing reverse DNS lookup (in this case maybe not) or you have DNS and/or mDNS disabled on your Linux Lite machine somehow (nsswitch. conf I think) Have you tried to set a Samba connection hostname different than the hostname you assigned to your laptop? Are you running this scan from a Windows or a Linux machine? Are you scanning from the laptop itself? I can't give a definitive answer without knowing what machine you are running the scan from.TC
