SOCKS5 optionally provides authentication so only authorized users may access a server. Practically, a SOCKS server proxies TCP connections to an arbitrary IP address, and provides a means for UDP packets to be forwarded.
How to use Socks5?

I created an Ubuntu 22.04 VM on AWS EC2 and used the docker to speed up the setup.
Run commands below to start a Socks server:
sudo docker run -d --name socks5 -p 1080:1080 -e PROXY_USER=<PROXY_USER> -e PROXY_PASSWORD=<PROXY_PASSWORD> serjs/go-socks5-proxy
Notes: make sure the firewall is enable to the port you specific.
Test Socks5 with curl
On the client side, run commands below:
curl --socks5 <Socks Server IP>:1080 https://ifconfig.me/ip -U <PROXY_USER>:<PROXY_PASSWORD>
