Step 1 - Spin up a Ubuntu 12.10 x64 droplet

Step 2 - Install Squid

				
					apt-get install -y squid

update-rc.d squid3 defaults

Step 3 - Setup Access Restrictions

Since this Squid proxy would allow anyone using it to make connections from your droplet’s IP address, you would want to restrict access to it.

You can register a free dynamic IP from services like noip.com

If you would like to use this Squid proxy from your phone, you would have to install a dynamic DNS update client.

You can use applications like Dynamic DNS Client for Android, or FreeDynPro for iOS.

Once you have a dynamic IP hostname, you can update it from your router at home, mobile device, or an API call.

This hostname should be added to /etc/squid3/squid.conf. Edit the file and add your hostname (nyproxy1.no-ip.org in our case):

				
					acl myhost srcdomain nyproxy1.no-ip.org

http_access allow myhost

Setup a crontab that reloads Squid every hour, in case your IP address changes:

				
					echo 0 */1 * * * service squid3 reload &gt;&gt; /var/spool/cron/root

Step 4 - Configure Squid Proxy

By default, Squid listens on port 3128. If you would like to use a different port, modify /etc/squid3/squid.conf

				
					http_port 3128

If you would like to browse through this Squid proxy and not have it detected as a proxy, setup anonymous settings by adding these lines to /etc/squid3/squid.conf:

				
					via off

forwarded_for off
