Welcome back to Dev Odyssey Home Networking! In this episode I visually explain how HTTP and Socket Secure (SOCKS5) proxies work. In this video, I show you how to set up an HTTP and SOCKS5 proxies using Squid and Ubuntu LTS with OpenSSH. Then we test out these proxies using Postman and FoxyProxy plugin for Firefox. Proxies have many benefits, some of which are increased anonymity browsing online, enabling access to different online content, a means to analyze web traffic, parental blocks on website, and much more. Once you know how to create and connect to proxies, your benefits are limited to your imagination.

There are many different proxy services and protocols, but in this case, we will be discussing the most popular, HTTP(s) and SOCKS (Socket Secure) proxies.

Install squid (sudo apt install squid) 2. Make copy of (sudo cp /etc/squid/ /etc/squid/) 3. Edit (sudo vim /etc/squid/), uncomment http_access allow localnet, save file 4. Restart Squid (sudo systemctl restart squid) 5. Check if its running (sudo systemctl status squid) Should see “running“ and “active“ 6. Configure Proxy in Postman and test (Settings, then Proxy tab). Add IP of Proxy Server, then default port (3128) 7. Check Access log for entries (sudo vim /var/log/squid/) 8. Add basic user / password for authentication 1. Add the following 1. auth_param basic program /usr/lib/squid/basic_ncsa_auth /etc/squid/htpasswd 2. auth_param basic realm Squid Proxy Caching Web Server 3. acl authenticated proxy_auth REQUIRED 4. acl authenticated_ips src {{CLIENT_IP_ADDRESS}}/32 5. http_access allow authenticated authenticated_ips 1. Run the following replacing “username” and “password” accordingly: sudo printf “USERNAME:$(openssl passwd -crypt PASSWORD) “ | sudo tee -a /etc/squid/htpasswd 2. Restart Squid 3. Configure Postman to use Proxy Auth (Settings then Proxy). Fill in Username and Password SOCKS Proxy 1. Login to Ubuntu Server using SSH, with -D flag for dynamic port forwarding * Dynamic Port Forwarding. - Creates a SOCKS proxy server that allows communication across a range of ports. 2. Configure Foxy Proxy By Adding a new Proxy, then changing the type to “SOCKS5“, IP Address as your localhost (127[.]0[.]0[.]1), and port you used (40932) 3. Save Configuration with name Test SOCKS. Open new tab in Firefox, set FoxyProxy to use Test SOCKS Other Dev Odyssey Network Videos: How to Create a VLAN - A Beginner’s Guide // OpenWrt - What is Port Forwarding? - How to Connect 2 Routers on the Same WiFi Network - What is a WAN Port On A Router? - Home Networking Playlist Network Security Playlist Icon Attribution Icons made by Freepik from Flaticon Icons made by Vectors Market from Flaticon Icons made by Smashicons from Flaticon Ubuntu is a trademark of Canonical Squid Artwork Creative Commons — Attribution-ShareAlike 3.0 Unported — CC BY-NC-SA 3.0 Music Attribution Sunrise by SKIRK Creative Commons — Attribution-ShareAlike 3.0 Unported — CC BY-SA 3.0 Free Download / Stream: Music promoted by Audio Library
