Hello all !
I spent several hours, trying to find a way around a problem with dns lookup ... but no joy ...
Here is my problem.
#1 asterisk dns request.
Running an asterisk system with NO internet connection, asterisk get 'stuck' for 60 seconds (dns timeout ?) on startup ... I don't know exactly why it's doing a dns lookup and i tried to eliminate everything i could think that may 'trigger' it ... no success ... no matter what i try it gets stuck
Here is a display of asterisk traces with the exact location where it 'blocks' ...

+===========================+
Any suggestion about the cause of this lookup and / or how to disable this ?
(Of course there are no registration nor anything that i see that could require a DNS lookup ... )
#2 As an alternative i thought of reducing dnsmasq dns lookup timeout ... but could not find how to do it ?
Anyone can tell me how to do this ?
P.S. I tried kill the dnsmasq process ... same result (maybe a shorter timeout ... but still very long ...)
... and everything else i could think of ...
Any suggestion would be appreciated ...
