This is a simply configuration settings for “Squid” server to be used as a proxy server to forward the connection thought the server.

Digested Authentication also added to force users who are not white-listed to  authenticate before using the server. White-listed IP addresses won’t be authenticated for simplicity. 

# File /etc/squid/squid.conf
#+++++++++++++++++++++++++++

# Create Cache Directory
cache_dir ufs /opt/squid/var/cache/ 500 16 256

# Access Control List for users
acl my_machine src 192.168.1.250
acl ubuntu src 192.168.1.52
http_access allow my_machine
http_access allow ubuntu

#Authentication with digest mode -  PASSWORD SENT IN MORE SECURE WAY AND DIGESTED 
auth_param digest program  /usr/lib/squid/digest_file_auth -c /etc/squid/passwords
auth_param digest realm proxy
auth_param digest children 5

acl authenticated proxy_auth REQUIRED
http_access allow authenticated
