Re: [Dnsmasq-discuss] Serving out NetBIOS reverse results?
Hi Vincent, I have dnsmasq 2.57 and reverse DNS resolution works on the server against hosts stored in /etc/hosts. Manual entries in /etc/hosts work for me too, but I was interested in trying if dnsmasq could also be made to serve reverse queries for the dynamic NetBIOS names. That is, names that (DHCP-configured) Windows hosts advertise in their SMB workgroup. The NetBIOS reverse lookup can be done manually by nmblookup -A ip address, so I was wondering if there's either some internal support for NetBIOS/Samba/Wins or perhaps a mechanism to plug in new dynamic query methods (e.g. shell one-liners) to implement this with dnsmasq. One way to implement this might be to write a cron script that parses system log for DHCP acks, performs an nmblookup against them and stuffs them into /etc/hosts but that's too kludgish for my taste. This is basically just for administration, diagnostics and completeness' sake anyway -- I doubt any program actually *requires* reverse lookups for NetBIOS. -Jarno ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss

That is, names that (DHCP-configured) Windows hosts advertise in their SMB workgroup. If my memory serves me right Windows does not need WINS as NetBIOS over TCPIP does the same. Every Windows machine can be a master browser and an election is triggered on the network to decide which workstation will be the master browser. So you don't need to change anything to dnsmasq in fact as it should already be working -- somebody correct me if I'm wrong. Also note that, as a personal experience return, we ran several times into troubles at work with WINS running alongside DNS. For instance when we were using vnc viewer to remote control a computer using its FQDN name we ended up on the wrong machine because WINS and DNS weren't in sync. And if I'm still right Windows first makes a NetBIOS query before falling back onto DNS. In fact DNS should be preferred over WINS. Any time. WINS is just a trouble maker.

[Dnsmasq-discuss] Serving out NetBIOS reverse results?
Hi, I'd like to configure dnsmasq to answer reverse IP queries for Windows workstations, replying with their NetBIOS names (perhaps by querying a Wins server or doing an nmblookup -A). Any ideas on how to achieve this? Current situation: 1) Dnsmasq is serving Windows workstations from a Linux server 2) Samba (v3) works as a Wins server on the same server 3) Manual reverse lookups work: nmblookup -A ip address 4) I can ping NetBIOS names from the server (/etc/nsswitch.conf configured correctly) 5) Reverse queries agains dnsmasq work for hosts that are manually entered into /etc/hosts ...but, obviously... 6) nslookup 192.168.1.68 on the server gives ** server can't find 68.1.168.192.in-addr.arpa.: NXDOMAIN -Jarno ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
