[SR-Users] Re: Internal DNS resolver

2024-01-12 Thread Igor Potjevlesch via sr-users 
You're right, sorry:

kamcmd dns.add_srv _sip._udp.example.com 3600 0 50 5060 srv1.com 2

kamcmd dns.add_srv _sip._udp.example.com 3600 0 50 5060 srv2.com 2

kamcmd dns.add_a srv1.com 3600 192.168.1.1 2

kamcmd dns.add_a srv2.com 3600 192.168.1.2 2



Finally, it looks to work fine by adding:

dns_srv_lb=yes

use_dns_failover=yes

Just so ppl you're asking don't lose their minds either trying to be 
clairvoyants of your particular setup, can you post what records exactly were 
added and what makes you think they are not followed by Kam when selecting a 
destination?



So you add records with dns.add and then lookup them up with dns.lookup

Hello,

the core rpc lack proper documentation, not like the case of modules. In this 
case, the code should be suggestive of what parameters have to be provided:

  - https://github.com/kamailio/kamailio/blob/master/src/core/dns_cache.c#L4744

For each of those values, the corex docs for dns_cache parameter should give 
details.

Cheers,
Daniel

Hello!



I have a quick question about the internal DNS resolver and cache embedded in 
Kamailio.

Is the ability to add an entry with dns.add_a bypass the "real" DNS lookup? So, 
let's say that sip.example.com <http://sip.example.com>  is publicly resolve 
alternatively with 1.2.3.4 & 5.6.7.8.9, if I do a dns.add_a to add my own 
sip.example.com <http://sip.example.com>  with, alternatively, 127.0.0.1 and 
127.0.0.2, will it work?





yes, it should work, the internal cache is checked first and if entry found, 
then it is used.

You can also add entries in the dns cache at startup via dns_cache modparam 
from corex.
