Hi George,
you could set the used dns server in Kamailio to only one and setup an
dnsmasq for example that is number one in /etc/resolve.conf.
dnsmasq can handle /etc/hosts as source or you combine your dns domain with
upstream dnserver (so dnsmasq ask for domain foo your server baa).
If you turn on dns request logging in dnsmasq you see what your server is
doing / asking for.
Just as an tricky hack. I needed that for one carrier that used split brain
dns in public.
Cheers
Karsten

Hello all,
I've come across this today when trying to setup DMQ replication:
root@sbcpub0-stage-lhe0-cn1:/root# systemctl restart kamailio
root@sbcpub0-stage-lhe0-cn1:/root# kamcmd dmq.list_nodes
{
host: 172.30.154.189
port: 5090
resolved_ip: 172.30.154.189
status: active
last_notification: 0
local: 1
}
root@sbcpub0-stage-lhe0-cn1:/root# getent hosts dmq-ng.services.domain.com
172.30.154.189 dmq-ng.services.domain.com
172.17.130.13 dmq-ng.services.domain.com
root@sbcpub0-stage-lhe0-cn1:/root# grep dmq-ng /etc/kamailio/*
/etc/kamailio/kamailio-module-params.cfg:modparam("dmq",
"notification_address", "sip:dmq-ng.services.domain.com:5090")
In another case, where the resolving IPs for the DMQ service hostname were
listed as A records in DNS, this worked as expected.
In this case, the second host of the DMQ group is not listed in
dmq.list_nodes, despite its being set in /etc/hosts, as shown by the getent
command.
Doesn't kamailio use nss for hostname resolution? Am I missing something
else? Thanks!
BR,
George
