Squid Caching Proxy Server

Squid 6.14 caching web proxy with Webmin on Ubuntu 24.04 LTS, closed by default: every request needs a proxy username and password, and anything not explicitly allowed is denied. Give servers in private networks one controlled way out to the internet, send traffic through a single fixed IP address, and save bandwidth by caching repeated downloads. Proxy users are added or removed with one command.

Getting started

From launch to signed in, step by step.

  1. Subscribe on AWS Marketplace and launch in your region with TCP 3128 open only to the addresses that will use the proxy (never 0.0.0.0/0), plus 22, 80 and 8000; wait a few minutes for first boot.

  2. Port 3128 is a proxy, not a web page: set http://<instance-public-ip>:3128 as the HTTP and HTTPS proxy in your browser, system or tool, with username proxyuser and your EC2 Instance ID typed with a capital leading I as the password (for example I-0123456789abcdef0).

  3. Test it: curl -x http://<instance-public-ip>:3128 --proxy-user proxyuser:<password> https://checkip.amazonaws.com prints the proxy's IP. The landing page at http://<instance-public-ip>/ repeats these details.

  4. Webmin is on port 8000 with username admin and the same capital-I password. SSH as ubuntu with your key pair. Change passwords with sudo bash /home/ubuntu/iscripts/pass_proxy.sh or pass_webmin.sh, manage users with proxy_users.sh, and check the server with sudo squid-status.

Security posture

What this image does and does not ship with, one fact per line.

  • Clean-room build on Canonical's official Ubuntu 24.04 LTS image: every component comes from its own official source, and nothing is copied from any third-party image.

  • Squid comes from Ubuntu's own repository with all security updates applied.

  • No credentials ship in the image: on first boot every instance sets its own proxy and Webmin passwords from EC2 instance metadata (IMDSv2) and creates its own server keys.

  • Every request must authenticate, and the access list denies everything not explicitly allowed.

  • Requests to the instance metadata service over IPv4 and IPv6 and to link-local addresses are blocked, so the proxy cannot be used to read the server's own credentials.

  • SSH is key-only, and build-time SSH keys, host keys, machine ID, shell history and logs were removed before imaging.

  • The bundled password tools enforce at least 10 characters with upper- and lower-case letters, a number and a symbol.

  • Open port 3128 only to the networks that need it, and restrict ports 22 and 8000 to trusted IP ranges in your security group.
