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
