Re: [squid-users] Help with accelerated site

Hi Ron,
Thanks for your reply and thanks for your time

This is perhaps the 10th time I uninstalled it and reinstalled it
And this is the very first time I could access my websites internally,
externally nothing yet, I am still getting the error
The following error was encountered while trying to retrieve the URL: /

  Invalid URL

Some aspect of the requested URL is incorrect.

Some possible problems are:

  a.. Missing or incorrect access protocol (should be http:// or similar)

  b.. Missing hostname

  c.. Illegal double-escape in the URL-Path

  d.. Illegal character in hostname; underscores are not allowed.

Your cache administrator is webmaster.

My clients can all access the internet, Yes I am sure that there's a
misconfiguration in my config file but I followed every tutorial

trying desperately to get something up, after a while you're saturated and
very tired, bouncing from on issue to another

I checked and triple checked my iptables rules everything looks fine so far

For instance, my backend server is listening right now on port 81, why did I
put it on port 81 because I was getting

Cannot bind to .... in the log file

so I changed it to 81 and I am getting the same error, there's absolutely
nothing else in my entire network that is using that port

So why can't it bind to port 81? You see the type of things that can drive
you through the wall

at the moment I have only three machines

A is Running the Proxy and the Router (IPTABLES)

B is the back end server

C is the DNS/DHCP servers

And only the backend server that is currently listening on port 81 and
before that it was listening on port 80

no matter which port I put in my config I get the "Cannot bind to ...." in
the log file

here is a bit of my config

*********************************************************************

http_port 192.168.1.3:81 accel parent vhost defaultsite=www.mysite.org

cache_peer 192.168.1.3 parent 81 0 no-query originserver name=main

acl dstdomain our_sites dstdomain www.mysite1.org www.mysite2.com
www.mysite3.net

http_allow_access main allow our_sites

http_peer_access main deny all

At the moment all of these sites are running on the same server
(virtualhost)

The only thing I am not sure of is probably the cache_peer directive

"cache_peer 192.168.1.3 parent 81 0 no-query originserver name=main"

If it's wrong then I don't know what to put in there

Regards

Adam
