Static WINS Entries Adding static entries to your Samba WINS server is actually fairly easy. All you have to do is add a line to wins.dat, typically located in /usr/local/samba/var/locks or /var/run/samba. Entries in wins.dat take the form of: "NAME#TYPE" TTL ADDRESS+ FLAGS where NAME is the NetBIOS name, TYPE is the NetBIOS type, TTL is the time-to-live as an absolute time in seconds, ADDRESS+ is one or more addresses corresponding to the registration, and FLAGS are the NetBIOS flags for the registration. A change that has been made to the wins.dat will not take effect until nmbd has been restarted. It should be noted that since the wins.dat file changes dynamically, nmbd should be stopped before editing this file. Do not forget to restart nmbd when this file has been edited. A typical dynamic entry looks like this: "MADMAN#03" 1155298378 192.168.1.2 66R To make a NetBIOS name static (permanent), simply set the TTL to 0, like this: "MADMAN#03" 0 192.168.1.2 66R The NetBIOS flags may be interpreted as additive hexadecimal values: 00 - Broadcast node registration 20 - Peer node registration 40 - Meta node registration 60 - Hybrid node registration 02 - Permanent name 04 - Active name 80 - Group name. The 'R' indicates this is a registration record. Thus 66R means: Hybrid node active and permanent NetBIOS name. These values may be found in the nameserv.h header file from the Samba source code repository. These are the values for the NB flags. nameserv.h 92 /* The wins flags.
