Introduction

Configurations
Squid Configuration
The squid.conf file is huge, with hundreds of options. In this howto we will only be changing a few settings. Open the squid.conf file for editing
gksudo gedit /etc/squid/squid.conf
Turn on line numbers in gedit (Edit > Preferences) Find the `http_port tag` (should be on or around line 53, its currently Line 89 in 7.10 release) By default it reads `# http_port 3128` This is the default port that Squid will listen on for requests. If you want to change it, uncomment the line and set the correct port. If you want Squid to listen only on one specific NIC, you can also change the IP address – for example `192.168.1.5:3128` Now we'll setup who is allowed access to the proxy. Find the http_access section (should start around line 1860,line 2589 in 7.04 and line 2608 in 7.10 release) Uncomment these 2 lines:
#http_access allow our_networks
You'll need to change 192.168.1.0/24 to match your network. Unless you have a second subnet you can delete 192.168.2.0/24 if you get a startup error :- 'FATAL: Could not determine fully qualified hostname. Please set visible_hostname' you will also need to modify the visible_hostname tag (around line 2909 in 7.10) to:- NOTE: this needs to be added as a new line in 7.10 (not sure about other releases) as there is no commented out line re-introduce.
visible_hostname localhost
Save the file and close gedit
Service administration
Fire up Squid If it is not running you can use :-
sudo /etc/init.d/squid start|restart|stop
then this will work
squid -k reconfigure
