Re: [Samba] Keeping a list of NetBIOS names on a network?
Thanks for the very detailed answer! For what it's worth, I've found smbtree -NS seems to give the output I'm looking for. Now I'm just looking for a more programmatic interface to get that same information. :) -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba

Thanks for the help so far! :) Matthew, The nmbd utility is akin to the Microsoft Windows Browser Service. It also provides the WINS Service IF wins support = Yes is set in the [global] stanza in the smb.conf file. The list of NetBIOS names that is in use within a particular network is complete only IF: a) All windows systems are configured to use NetBIOS over TCP/IP b) Samba is correctly configured either as a WINS server, or as a WINS client. c) If Samba is NOT the WINS server, then a Windows Server must provide the WINS server service. d) All Windows clients have been configured to use the WINS server. e) The WINS database is NOT corrupt. If the above are NOT complied with, the local browse list will not be complete for all NetBIOS names that are in use within the scope of the entire network. The Samba NetBIOS extensions (that are used only by nmbd) to get around bad WINS implementations, or where it is not used, are not 100% reliable in assuring a complete list of NetBIOS names. These extended features are: remote browse sync remote announce All clients and servers on which NetBIOS over TCP/IP has been enabled will participate in the election of the local master browser. The heuristics by which the master browser is elected is somewhat complicated. Samba's OS Level is a means of prejudicing the election criteria in favor of the Samba server if it is set high enough - but it does NOT guarantee that the Samba server will win the election. If you do not run nmbd on your Samba server then there is no way for Samba to participate in NetBIOS browsing processes. Only nmbd sends out the NetBIOS workgroup announcements and the NetBIOS host announcements that are necessary for Samba to participate in the browse master election process, and that are necessary for Samba to appear in a browse list. The solution to network browsing problems and inconsistencies in the NT4 domain and workgroup networking world is to use nmbd and WINS. Active Directory does not depend on WINS, instead it uses a combination of LDAP and DNS for browse list handling. However, it is possible to enable NetBIOS over TCP/IP on any Active Directory member Windows system and thereby ensure that it participates in the NetBIOS-based browsing process. The ability to find a NetBIOS name on the network presupposes that the particular node that might own such a name has been correctly configured to support NetBIOS over TCP/IP. In the absence of a WINS Server but with enablement of NetBIOS over TCP/IP even ADS domain members can participate in NetBIOS-based browse list management. I hope that answers your questions. - John T. -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
[Samba] Keeping a list of NetBIOS names on a network?
I'm trying to make some DNS server software aware of NetBIOS names on the local network. Is there an easy and efficient way using Samba to keep track of what NetBIOS names are present?

Another alternative would be to look at integrating your DNS server with nmbd, perhaps using the wins.dat (or whatever the WINS db is backed up to now). cheers, jerry -- = http://www.plainjoe.org/ What man is a man who does not make the world better? --Balian signature.asc Description: OpenPGP digital signature -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba

winbindd has the capability of doing hostname resolution for NetBIOS names and can then be added to nsswitch.conf. Check out the man pages.

Actually it looks like this is only available for IRIX.
