Trying to run smbtree command fails with: $ smbtree smbc_opendir: File o directory non esistente I can't find anything providing smbc_opendir. Searching in the net it seems it should be provided by samba package itself.
You need to have netbios name resoluiton configured, see: https://wiki.samba.org/index.php/FAQ#Why_does_Windows_Network_Neighborhood_not_show_Samba_server.28s.29.3F It will be addressed with a better error message in the next Samba version: https://gitlab.com/samba-team/samba/-/merge_requests/2078
