SSH over HTTPS with proxytunnel and nginx
- by Thermionix
I'm trying to setup an ssh over https connection using nginx. I haven't found any working examples, so any help would be appreciated!
~$ cat .ssh/config
Host example.net
Hostname example.net
ProtocolKeepAlives 30
DynamicForward 8118
ProxyCommand /usr/bin/proxytunnel -p ssh.example.net:443 -d localhost:22 -E -v -H "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Win32)"
~$ ssh [email protected]
Local proxy ssh.example.net resolves to 115.xxx.xxx.xxx
Connected to ssh.example.net:443 (local proxy)
Tunneling to localhost:22 (destination)
Communication with local proxy:
-> CONNECT localhost:22 HTTP/1.0
-> Proxy-Connection: Keep-Alive
-> User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Win32)
