[squid-users] DNS lookup fails initially for FQDN in squid

[Aashima Madaan]

>* Hi,

*>* that name initially

Please define "initially" - do you mean:

 - when the squid server is booted up
 - when the squid service is started on an already-running server
 - something else?

@Aashima - initially here means when I start squid service

>* My concern is why there is so much delay in resolving fqdn of an ip. *
What is your DNS setup?

@Aashima - We got company DNS servers which we have added in our
/etc/resolv.conf of that squid machine.

Where is the Squid server pointing for its DNS
resolver?

@Aashima - I see in cache.log that its adding nameservers from /etc/resolv.conf

2016/05/27 10:32:52 kid1| Adding nameserver 8.8.8.8 from /etc/resolv.conf

Is that DNS server running and answering queries before the Squid

server/service starts up?

@Aashima I do curl/ping/nslookup for icap server from squid machine,
it is able to resolve that particular ip.


Thanks
