Install squid

plain old apt-get update && apt-get install squid3 apache2-utils -y

Basic squid conf

/etc/squid3/squid.conf instead of the super bloated default config file

# note that on ubuntu 16.04, use squid instead of squid3
auth_param basic program /usr/lib/squid3/basic_ncsa_auth /etc/squid3/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated
forwarded_for delete
http_port 0.0.0.0:3128

Please note the basic_ncsa_auth program instead of the old ncsa_auth

Setting up a user

sudo htpasswd -c /etc/squid3/passwords username_you_like, on 16.04, it's squid, not squid3 and enter a password twice for the chosen username then sudo service squid3 restart

centos

I have to use centos, since adsl providers are not capable of providing ubuntu
