From a local computer, we can typically log in via SSH using the following
command: ssh -p 8022 server_user@server_ip
Next, run python3 -m http.server -d ./src 8080 on the server.
But, directly accessing the server's content through
http://serverip:server_port may not work due to security restrictions. We can
overcome this using SSH tunneling.
For instance, on Android, we must first choose a valid port (e.g., 8080) for the server (ports like 3000 and 80 may not be valid). After running the server (e.g., mdbook, Python), the content will not be immediately accessible locally. We need to establish a forward tunnel to the server, mapping the server's port to a local port (e.g., 3001).
ssh -p 8022 -L 3001:localhost:8080 -L 3002:localhost:8081 server_user@server_ip
# OR
ssh -p 8022 -L 8080:localhost:8080 -L 8081:localhost:8081 server_user@server_ip
Now, the server's content will be accessible locally via
http://127.0.0.1:3001/ or http://127.0.0.1:8080/.
Therefore, to ensure proper website functionality, we must identify an available port on the server and utilize SSH tunnel forwarding.
