Samba Port Requirements
I'm setting up a firewall for a guy and he is running samba...
I noticed that samba has four ports it listens on.
netbios-ns/udp (Netbios Name Service)
netbios-dgm/udp (Netbios Datagram Service)
netbios-ssn/tcp (Netbios Session Service)
microsoft-ds/tcp (Microsoft Domain Service?!?)
I can take the logical guess and say netbios-ns, netbios-ssn, and probably microsoft-ds are totally neccesary for running a Windows Domain Server and doing filesharing. My question is what the heck do they use the dgm service for?
