RE: [squid-users] Squid using a different DNS server

Actually, it looks like I am running 2.4 STABLE 1. The DNS issue is
still a problem, it's still DNSing bdogg.example.com to my ipmasq's
external ip address, rather than using the named server on the localhost
to DNS it to a specific, internal webserver. It couldn't be because I
don't have 2.4 STABLE 4 correct?

        You haven't turned on the http acceleration options.
        Search the config file for httpd_accel or http_accel.. one
        of the two.

        You need to turn it on
        probably use 'virtual', since you're using your own DNS server
to do the mapping to the backend hosts.

Cool, we're making progress.

I uncommented the httpd_accel_port 80 line in my conf file and added
httpd_accel_host virtual. I then got this error:

ERROR
The requested URL could not be retrieved

------------------------------------------------------------------------
--------

While trying to retrieve the URL: http://12.254.159.101/

The following error was encountered:

Access Denied.
Access control configuration prevents your request from being allowed at
this time. Please contact your service provider if you feel this is
incorrect.

Your cache administrator is root.

Looks like it's trying to fetch from my ipmasq's external
address...which is what attbi and other DNS servers on the internet have
as it's ip, but my internal DNS server knows otherwise.

        If you want to turn on the squid to be a Proxy _AND_ an
accelerator, then turn that option on, but be very careful rwith
your rules. They SHOULD look like this in this case:

To be a proxy and an accelerator... What are the gains from doing this?
Will it just acting as an accelerator handle my current situation?

        <rules>

Added to my conf file.

        .. this way you limit requests to either:

        * from ALL to your local webserver network, or
        * from your local network to ALL.

        Note, the dst ACL works with whatever your DNS Maps the
webservers to, rather than the "public facing" ips, obviously as
long as you have the DNS setup rightr. I'd use a hosts file (either
/etc/hosts by default, or you can change this in the squid.conf
file) to do the localised webserver -> local ip mapping. Thats how I do
it.

        Good luck, and tell me how it goes!

No dice...yet :)
