samba nmbd: query_name_response: Multiple (2) responses received

  • 772

The nmbd logs of a linux samba4 domain member server are filled with lines like:

query_name_response: Multiple (2) responses received for a query on subnet 192.168.1.54 for name ADOMAIN<1d>.
This response was from IP 192.168.1.19, reporting an IP address of 192.168.1.19.

where:

  • 192.168.1.54 is the IP of the member server
  • 192.168.1.19 is the IP of the PDC
  • ADOMAIN is a SAMBA NT-style domain

Those lines appears every 5 minutes.

What is going on?

Random steps taken:

  • rm /var/cache/samba/browse.dat;
  • double check interfaces broadcast configuration (it is correct);
  • systemctl restart nmbd (a evergreen classic).

  1. It could be because of a host in the same physical network which have two interfaces. The broadcast query coming in is replied to both of them by your nmbd. Please see this 17 years old answer at https://thr3ads.net/samba/2000/08/1675707-query_name_response-Multiple-responses-received

  2. For me, the answer was to be found here: https://forums.freebsd.org/threads/samba-multiple-2-responses-two-freebsd-systems-on-my-network.65759/
    And specifically the last sentence

    If you are doing standalone, then you should have local master = no, domain master = no and preferred master = no. Disable all the wins stuff too. I think all you would need is workgroup = WORKGROUP

    However, I don't use an NT domain to log on to. I actually use nothing more than a workgroup. the "prefered master = no" was the one I had to change. I had it set to 'yes' on 1 host. Changed to 'no' and restarted samba. Everything kept working after that and the messages stopped.
