A docker image with OpenSSH server configured for tunneling TCP connections.

Supported environment variables:

• USER - a login of a user (optional, default value: anonymous).
• PASSWORD - a password of that user (optional, default value is randomly generated).
• AUTHORIZED_KEYS - keys that should be written to ~/.ssh/authorized_keys (optional, default value: none).
• AUTHORIZED_KEYS_PATH - a path to a file that should be copied to ~/.ssh/authorized_keys (optional, default value: none).

On the remote side:

docker run -d -p 443:22 -e USER=user -e PASSWORD=1234 sekogan/tunneling-ssh

Create a SOCKS proxy on your PC:

ssh -D 1234 -p 443 -N user@<your server url>

Then configure your browser to connect to the localhost:1234 SOCKS proxy and verify it forwards all connections to the remote side.
