I needed an HTTP proxy for testing busalert today so my Raspberry Pi was temporarily turned into a proxy server. Here’s the steps I needed to follow to get it to work.

Install Squid

sudo apt-get update
sudo apt-get install squid3

Edit Configuration

Open /etc/squid3/squid.conf in an editor and uncomment the following lines to make Squid accept connections:

#acl localnet src 192.168.0.0/16 # RFC1918 possible internal network
#http_access allow localnet

(You’ll have to change these if your local network isn’t 192.168.0.*)

Restart Squid

sudo service squid3 restart

Configure clients

Change the proxy settings for the client machine to use an HTTP and HTTPS proxy at the IP address of your Raspberry Pi on port 3128.

Verifying the proxy is working

Use sudo tail -f /var/log/squid3/access.log to view the access log for Squid and check that your requests on the client are being routed through the proxy.
