SSH through HTTPS
Posted by jpluimers on 2020/05/04
Often, hotspots only allow http/https traffic. Other traffic – like SSH – is blocked. Nowadays, fewer hotspots block that, but too many still do.
So it can be worth a while to route your SSH server through HTTPS (I don’t like Web-based SSH that much as terminal emulation in browsers isn’t that well yet, but that seems to change rapidly, more on that in the “Further reading” section below).
After some background reading at apache – Tunnel over HTTPS – Stack Overflow, here are a few links that help you do it:
Server side: DAG: Tunneling SSH over HTTP(S).
You need:
- An internet connected Apache server (eg. with IP address 10.1.2.3)
- A FQDN that points to this IP address (eg. ssh.yourdomain.com)
- A virtual host configuration in Apache for this domain (eg. /etc/httpd/conf.d/ssh.yourdomain.com.conf)
- A configuration to adapt ssh to use the HTTP tunnel

Steps:
- Test of it works at all
- Edit your local ~/.ssh/config file to redirect SSH to HTTPS

Not all proxy configurations and hotspots support this. But it might be worth a look: SSH Over Proxy.
