Introduction
As we all know, sometimes, it’s hard for us to connect our remote server directly or the connection is not stable, we have to conduct some method to access our remote server.
Method
Using some 3rd party application
FinalShell: We can set proxy directly
Windows
It’s not friendly to Windows
Note: on Windows, an easy option is using PuTTY/FinalShell and configuring the SOCKS5 proxy in the client settings.
Linux
We can use nc and ssh itself to proxy ssh trafic.
ssh -o "ProxyCommand=nc -x socks_proxy_host:socks_proxy_port %h %p" user@remote_host(base) firstsnow@DESKTOP-7DDCJ5H:~/.ssh$ ssh -o "ProxyCommand=nc -x 192.161.0.101:7897 %h %p" root@xyz.xxxxx.online
The authenticity of host 'xyz.xxxxx.online (<no hostip for proxy command>)' can't be established.
RSA key fingerprint is SHA256:As8XEpRKA0TtNH5poEgpTI5LqZmId0WZnQowWqJMcME.
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

rootNOTE: If you can’t access your server through proxy, that could because your proxy service banned traffic through port 22. The best way is to find and change a proxy server merchant who allow traffic through port 22.
