When looking at /etc/services one can see netbios-ns, netbios-dgm and netbios-ssn being defined as "NETBIOS foo" where as this is not entirely true, because UDP and TCP are actually NetBIOS over IP (NetBT, NBT) A more proper name would be NetBIOS over TCP/IP. Reproducible: Always Steps to Reproduce: 1. Open /etc/services 2. Search for netbios- Actual Results: netbios-xy 13x/xyz # NETBIOS XYZ Service Expected Results: netbios-ns 13x/xyz # NetBIOS over TCP/IP XYZ Service Actually the first part is also inaccurate, but I bet things would break if you change it.
our /etc/services reflects IANA: http://www.iana.org/assignments/port-numbers
maybe WONTFIX would have been better, but oh well ...
