Description Chris Smith 2010-05-09 10:49:53 UTC 
Running samba-3.5.2 I notice this in the log.nmbd file after starting samba:
===============================================================
[2010/05/08 19:10:44.652249,  0] nmbd/nmbd_packets.c:738(queue_query_name)
 queue_query_name: interface 1 has NULL IP address !
[2010/05/08 19:10:44.652298,  0] nmbd/nmbd_packets.c:738(queue_query_name)
 queue_query_name: interface 1 has NULL IP address !
===============================================================

I discovered that this occurs with:
bind interfaces only = Yes
and one of the following:
===========================
interfaces = 192.168.107.6 lo
or
interfaces = eth0 lo
===========================

no other combinations cause the issue:
===========================
interfaces = 192.168.107.6 127.0.0.1
or
interfaces = lo 192.168.107.6
or
interfaces = lo eth0
or
interfaces = 127.0.0.1 192.168.107.6
or
interfaces = 127.0.0.1 eth0
===========================

Basically only when "lo" is specified second by name is the problem
seen, "lo"'s IP address works in all cases either first or second.

Adding the output of "ip addr" in case that helps:
========================================================
# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
   inet 127.0.0.1/8 scope host lo
   inet6 ::1/128 scope host
      valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
state UP qlen 1000
   link/ether 00:16:76:aa:bf:70 brd ff:ff:ff:ff:ff:ff
   inet 192.168.107.6/24 brd 192.168.107.255 scope global eth0
   inet 192.168.107.66/24 brd 192.168.107.255 scope global secondary eth0
   inet6 fe80::216:76ff:feaa:bf70/64 scope link
      valid_lft forever preferred_lft forever

Metze, Jeremy, does this ring a bell ?
Comment 2 Stefan Metzmacher 2010-05-27 05:56:45 UTC
