Whenever you use -U for WINS queries, you must also use -R to force recursion. (If that's the case, why would one ever use -U without -R?) So if you use WINS with BackupPC, you can use nmblookup -U wins-server-address -R as your host lookup function. If BackupPC is running on the same host as nmbd, use nmblookup -U 127.0.0.1 -R. -- Malware Security Report: Protecting Your Business, Customers, and the Bottom Line.

[BackupPC-users] WINS server (nmbd) puzzle
My client Windows XP boxes are failing to register with my WINS server (running nmbd from Samba). I'm puzzled how to figure out what I'm doing wrong. I'm setting up BackupPC to back up my Windows clients using rsync. I've installed cwRsync to the clients. BackupPC uses nmblookup to find the client's IP address given its Windows NETBIOS name. I'm distributing the WINS server address via DHCP and see it on the client using ipconfig /all. I can run tcpdump on the server (filtering for this client and the NETBIOS port) and see the register/response sequence at UDP 137: MULTIHOMED REGISTRATION; REQUEST; UNICAST REGISTRATION; POSITIVE; RESPONSE; UNICAST REGISTRATION; REQUEST; UNICAST REGISTRATION; POSITIVE; RESPONSE; UNICAST If I signal the nmbd process with SIGHUP to make it dump its table to nmbd.log, I don't see client in the list. I do see the server and my Windows Active Directory server's records in the list, but no clients. nmblookup finds the client by broadcast (the client responds with the record) but nmblookup -U 127.0.0.1 says there's no record of it. (A query for the server's own record finds it, so I know the WINS service is at least working to that degree.) So why is nmbd not remembering client records? One thing I realized is that the Samba server is configured for one workgroup, and the client in question is in a different workgroup. Will nmbd not record records for workstations outside its workgroup? -- Special Offer -- Download ArcSight Logger for FREE!
