Introduction:
Squid server is a popular open source proxy and web cache. It has a variety of uses, from speeding up a web server by caching repeated requests, to caching web, name server query, and other network lookups for a group of people sharing network resources.
It is primarily designed to run on Linux / Unix-like systems. Squid is a high-performance proxy caching server for Web clients, supporting FTP, gopher, and HTTP data objects. Unlike traditional caching software, Squid handles all requests in a single, non-blocking, I/O-driven process.
Prerequisites:
a. Linux Machine Ex: RHEL5
b. squid-2.6.STABLE6-3.el5.i386.rpm
Installation on Linux
Use the following command to install SQUID RPM
# Rpm –ivh squid-2.6.STABLE6-3.el5.i386.rpm

No Authentication Configuration:
Specify the command for the external authenticator. Such a program reads a line containing "username password" and replies “OK" or "ERR" in an endless loop. If you use an authenticator, make sure you have 1 acl of type proxy_auth. By default, the authenticator_program is not used.
Change the http Access Parameter from http_access deny all to http_access allow all
Restart SQUID Proxy Server process
# /etc/ini.d/squid restart
Stopping squid: ................ [ OK ]
Starting squid: . [ OK ]
IE Proxy Server Configuration:
1. Open Internet Explorer
2. Go to Internet Options > Connections Tab > LAN Settings > Proxy Server
3. Enter IPAddress and Port of the SQUID Proxy Server
4. Try Accessing http://www.google.com
5. Done.

Basic Authentication Configuration:
Specify the command for the external authenticator. Such a program reads a line containing "username password" and replies "OK" or "ERR" in an endless loop. If you use an authenticator, make sure you have 1 acl of type proxy_auth. By default, the authenticator_program is not used.
Add the following configuration parameter to squid config file enable Basic Authentication.
auth_param basic program /usr/lib/squid/ncsa_auth /etc/squid/basic_passwd
Generate a basic authentication password file for any user “basic”
# htpasswd -c /etc/squid/basic_passwd basic
New password:
Re-type new password:
Adding password for user basic
Username: basic
Password file: /etc/squid/basic_passwd

2. Go to Internet Options > Connections Tab > Lan Settings > Proxy Server
3. Enter IPAddress and Port of the SQUID Proxy Server
4. Try Accessing http://www.google.com > Enter Username and password (basic) > Authenticate it
5. Done.
Digest Authentication Configuration:
Specify the command for the external authenticator. Such a program reads a line containing "username password" and replies "OK" or "ERR" in an endless loop. If you use an authenticator, make sure you have 1 acl of type proxy_auth. By default, the authenticator_program is not used.
Add the following configuration parameter to the squid config file to enable Digest Authentication.
auth_param digest program /usr/lib/squid/digest_pw_auth -c /etc/squid/digest
Create a digest.sh file to generate digest using the following script.
/etc/squid/Digest.sh
-------------------------------------------------------------------------------------------------------
#!/bin/sh
user=$1
pass=$2
realm=$3
if [ -z "$1" -o -z "$2" -o -z "$3" ] ; then
echo "Usage: $0 user password 'realm'";
exit 1
fi
ha1=$(echo -n "$user:$realm:$pass"|md5sum |cut -f1 -d' ')
echo "$user:$realm:$ha1"
-------------------------------------------------------------------------------------------------------
Give executable permissions to the above create file.
# chmod +rwx /etc/squid/digest.sh
#./digest.sh username password 'Squid proxy-caching web server' >>/etc/squid/digest
Generate a digest for the user “Admin” with the password “password”
#./digest.sh admin password 'Squid proxy-caching web server' >>/etc/squid/digest
Restart SQUID Proxy Server process
# /etc/ini.d/squid restart
