接下來，就是要使用 MobaXterm 來 SSH 連線到 VM 主機。
連線的方式如上，若是 DNS 可以解析到 域名，那就在 Remote Host 打上域名，若是還不能夠成功解析，那就先打上公用 IP（外部 IP）
成功的話就設看到這個畫面。
BUT！

Welcome back to Dev Odyssey Home Networking! In this episode I visually explain how HTTP and Socket Secure (SOCKS5) proxies work.

Follow me on a Twitter and Facebook!

In this video, I show you how to set up an HTTP and SOCKS5 proxies using Squid and Ubuntu 20.04 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.

A Proxy server is simply an intermediary, or middle man, that processes requests for you on their way out to their destination, acting as a client itself on your behalf. 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.

Demonstration

Squid Proxy
1. Install squid (sudo apt install squid)
2. Make copy of squid.conf (sudo cp /etc/squid/squid.conf /etc/squid/squid.conf.default)
3. Edit squid.conf (sudo vim /etc/squid/squid.conf), 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/access.log)
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)\n" | 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

榨乾 VM 主機 Part 2 - 使用 Docker 安裝 SOCKS5 Proxy Server 代理伺服器

今天主要的內容，將會使用 GCP 的主機，設立一個免費額度的 VM 主機，並且簡單的調教他，主要的目標是如果服務死掉時，至少還可以連線到 VM 主機，將該服務重啟或關閉，而不是服務死掉， VM 主機也跟著死掉了。
