Here comes an update to the old article on how to configure Squid. The new Squid 3.x which is available in Ubuntu 16.04 requires some different configuration.

Installation is easy. Just fire the following line:

apt install squid

The configuation file to edit is still located at /etc/squid/squid.conf. Make a backup of the original file and have to new one contain the following lines:

http_port 31280

auth_param basic program /usr/lib/squid/basic_ncsa_auth /etc/squid/passwd
auth_param basic children 1
auth_param basic credentialsttl 1 minute
auth_param basic casesensitive off

acl auth proxy_auth REQUIRED
acl localhost src 127.0.0.0/8

http_access allow auth
http_access allow localhost
http_access deny all

cache deny all

forwarded_for off

request_header_access Via deny all

In order to have users show some identification a password file with according hashes has to be set:

htpasswd -c /etc/squid/passwd USERNAME
chmod 400 /etc/squid/passwd && chown proxy /etc/squid/passwd

That should do it. Squid 3 will ask users for ID and password and proxy your requests.
