Note that NetBIOS names are qualified by a ``scope'' string. All machines that are to interact via NetBIOS must agree on the setting of the scope string. By using different scope names on different sets of machines, several disjoint NetBIOS name spaces may exist on one network.
The scope, internet addresses, and other parameters are set by the NetBIOS daemon, in.nbd. See netbios(ADMN) and in.nbd(ADMN) for further information.
Each open of /dev/netbios creates a new, distinct NetBIOS user environment. Each user environment has its own local name table, local session table, and permanent node name. Users in different NetBIOS user environments on a machine appear, to each other and to users on other machines, to be on separate machines.
This device should be accessed through the NetBIOS Transport Provider devices (see nbtpi(ADMP)). The actual protocol used to interact directly with the netbios driver is not documented here.
