我想通过端口 443 通过免费的公共 ssh 服务器使用 ssh 作为袜子服务器。
我访问提供此类服务的网站并获取以下信息： 帐户信息：
主机：server_ip（我用'server_ip'替换了实际的服务器ip）
Dropbear 端口：443、80
OpenSSH 端口：22
代理端口：8080
OpenVPN 端口：
PPTP端口：1723
用户名：user（我将实际用户名替换为“user”）
密码：通过
mkdir .ssh/
chmod 700 .ssh
ssh-keygen -t rsa -b 4096
cat .ssh/id_rsa.pub > .ssh/authorized_keys
chmod 600 .ssh/*
check ~/ to 755
check .ssh/ to 700
我的 ssh_config：

注意：dropbear 与 ssh v2 兼容；然后它应该与 openssh-client 一起使用（来源：https://en.wikipedia.org/wiki/Dropbear_%28software%29--> “Dropbear 在客户端和服务器中实现了完整的 SSH 版本 2 协议。” ）
ssh -D 1080 -vvv -p 443 user@server_ip
这是输出：
