I just upgraded OpenSUSE from Leap 42.3 to Leap 15.0, and with this upgrade, OpenSUSE moved its default firewall application from SuSEfirewall2 to Firewalld. I opted not to use the
susefirewall2-to-firewalld script for migration, but to rebuild my rules from scratch. However, I cannot seem to allow NetBIOS queries to return successfully on my client machine. I have enabled both the
samba-client services in Firewalld.
For a host
hostname, which I can ping because of DNS or access by IP address, and from which I can access my OpenSUSE machine via Samba, I try:
> nmblookup hostname name_query failed to find name hostname
What else do I need to do to allow a NetBIOS query to succeed?
