Set the DNS hostname for Squid cache server.

shobhit · 09-23-2007, 02:08 PM

I have a stand alone PC (running Fedora 7) which I use to connect to the net. I tried running squid on it, just to have its caching property to speed up net access.
I have installed squid-2.6.STABLE16 and it is up and running.

Code:

squid     9959  9527  0 Sep23 pts/6    00:00:00 ./squid -N -d 1 -D

Also the log says...

Code:

Next I configured firefox to use localhost.localdomain as proxy server and port 3128.
But I get the following error message.

Code:

    * 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.

I'd appreciate any help to get this fixed, please.

Thanks.

You don't need to use "localdomain" in your Firefox - localhost is fine. Personally, I use 127.0.0.1 so that it doesn't even have to look at /etc/hosts but it's all good. In any case, your problem is being caused by a bad ACL (or lack of a good one). This should be an easy fix. Let's see what your squid.conf looks like. Use this command to strip comments and spaces before posting:

Code:

cat /etc/squid/squid.conf | grep -v ^# | grep -v ^$

BTW, just to be clear: You are saying this Squid is only meant for use on localhost, right?

shobhit · 09-24-2007, 12:27 AM

I had already tried it without the localdomain it didn't work. Now I have also tried 127.0.0.1 still not working :-(

Yes I plan to use squid server on my localhost and use firefox from the same localhost to access the net.

Here's squid.conf

Code:

The squid startup log says squid is running on 0.0.0.0

Code:

2007/09/23 23:33:11| Accepting proxy HTTP connections at 0.0.0.0, port 3128, FD 14.
2007/09/23 23:33:11| Accepting ICP messages at 0.0.0.0, port 3130, FD 15.

Is that ok?

I suppose I put the log in as well :-)
Here is a part of it, it looks the same throughout :-(

add this code to your squid.conf

http_access allow localhost

shobhit · 09-24-2007, 01:53 AM

Yep! its working. In fact this post is going through squid.
Thanks a lot.

win32sux · 09-24-2007, 03:22 AM

Glad you got it working, I told you it would be an easy fix!

BTW, what are you using those localnet and our_networks ACLs for?

shobhit · 09-24-2007, 07:20 AM

You need only one of those not both, I realize that now :-)
I will remove one.
I was going through various documentation and web sites to fix this and I put that in to try to get it to work.

Is there any way to ensure that all inter net connection goes through squid only. Right now, I can choose to use the proxy setting for Firefox and therefore go through squid or connect directly. I have a new thread for that, kindly suggest.

If this is only for localhost then you don't need any 192.168.x.x lines at all. Also, I'd change the "http_port 3128" line to "http_port 127.0.0.1:3128" to make sure it only listens on localhost, and I'd remove the "icp_access" lines and use a "icp_port 0" line to disable ICP entirely.

I'm headed that way right now.

shobhit · 09-25-2007, 07:52 AM

What do you know, it is working without icp enabled too :-)
As I said I just put that in from somewhere, I have a long way to go with squid.
Its working without the 192.168.x.x lines too.
I guess that is because the squid server and client (Firefox) are both on localhost. If I want other machine I will have to put in that ip.

well you can do it if you're using transparent proxy...

shobhit · 10-03-2007, 10:11 PM

I tried setting up a transparent proxy, but its not working. And I am still trying to fix it.
Kindly have a look at

and let me know your thoughts.
