Hi,

I am having difficulty running named in a non-default rdomain, on the
following platform:

root@ns0 ~ # uname -a
OpenBSD ns0.whatever 5.0 GENERIC#36 sparc64


I have an interface in a rdomain '1':


root@ns0 ~ # ifconfig bge1 | head -1
bge1: flags=28843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,NOINET6> rdomain 1
mtu 1500

and happy:

root@ns0 ~ # ping -c 1 -V 1 10.20.30.2
PING 10.20.30.2 (10.20.30.2): 56 data bytes
64 bytes from 10.20.30.2: icmp_seq=0 ttl=255 time=0.215 ms



However, when I try to start the named daemon in that rdomain with the
following command:


# route -T 1 exec /usr/sbin/named -4 -i /var/run/named-gn.pid -c
/etc/named-gn.conf


the daemon starts successfully, but cannot open a control port on the loopback
interface, and complains thus:

Jan  1 09:12:19 ns0 named[23519]: [child]: disallowed port 954
Jan  1 09:12:19 ns0 named[23519]: /etc/named-gn.conf:21: couldn't add command
channel 127.0.0.1#954: address not available


This is fair enough I guess since the loopback interface is in the default
rdomain, and is thus unavailable to named process.


However if I instead explicitly configure the control port to be on the
correct interface (IP address), thus:


snippet from /etc/named-gn.conf :
controls {
   inet 10.20.30.2 port 954 allow {10.20.30.2;} keys {"rndc-key";};
};


then it also fails and complains thus:

Jan  1 09:01:49 ns0 named[8504]: [child]: disallowed port 954
Jan  1 09:01:49 ns0 named[8504]: /etc/named-gn.conf:19: couldn't add command
channel 10.20.30.2#954: permission denied
Jan  1 09:01:49 ns0 named[8504]: running


So I guess that named's (unprivileged?) child does not honour (inherit?) the
parent's rdomain, and thus cannot bind to either rdomain '0' or '1',
succesfully ?

To make matters worse, since I can't now use rndc to reload zones on the fly,
I tried to HUP the named process, but this also fails miserably (since it
appears to re-read the default config file instead)

Is this a bug, or am I doing something silly ?  (Suggestions regarding using
other DNS daemons are not really helpful unless they are 1. in base, 2. can
host both recursive & master services on the same IP/port)

thanks & happy new year !


/Pete
