tinyproxy on ubuntu

• sudo apt-get install tinyproxy
• in /etc/tinyproxy.conf add a line under Allow's to Allow 123.456.789.1/24 if your IP is within that subnet
• add a new crontab to restart tinyproxy
  • crontab -e
  • 0 22 * * * root service tinyproxy restart
• open the port 8888 (which is also configurable in /etc/tinyproxy.conf)
  • /sbin/iptables -I INPUT -p tcp --dport 8888 -m state --state NEW,ESTABLISHED -j ACCEPT
  • /sbin/iptables -I OUTPUT -p tcp --sport 8888 -m state --state ESTABLISHED -j ACCEPT
• Restart tinyproxy
  • service tinyproxy stop
  • service tinyproxy start
• In Firefox, Tools->Options->Advanced->Network->Configure how Firefox connects to the Internet, select "Manual proxy configuration", add IP address of your server and port configured for tinyproxy (8888 by default)
