Starting malai-0.2.3. You can share your local TCP server with the world. This can be your database server or ssh server for example.

$ malai tcp 5432 --public
Malai: Sharing port 5432
Run malai tcp-bridge <id52> <some-port>
to connect to it from any machine.

Now anyone can connect to this exposed server from their machine using malai tcp-bridge:

$ malai tcp-bridge <id52> 9091
Listening on 127.0.0.1:9091

This will start a TCP server on their computer and they'll use this TCP server as if they're connecting to your real TCP server running on port 5432.

So if it's a postgres server, they can connect to it using the following command:

psql 'postgresql://user:passwd@localhost:9091/db_name'

And it'll connect to your postgres server listening on port 5432 on your machine!

$ systemctl status sshd

You don’t need to expose port 22 publicly — malai connects to it locally on this machine.

To share the SSH port using malai tcp, run:

$ malai tcp 22 --public

Malai: Sharing port 22
Run malai tcp-bridge <id52> <some-port>
to connect to it from any machine.

On another machine, run the following to connect:

$ malai tcp-bridge <id52> 9090

Listening on 127.0.0.1:9090

Replace <id52> with the ID shown by the malai tcp command.

Once the bridge is running, you can SSH into the machine like this:

$ ssh -p 9090 user@localhost

Use the appropriate user that exists on the remote machine. The SSH connection goes to localhost:9090, where tcp-bridge is listening. It then forwards the traffic to the remote machine via the Kulfi network using <id52>.
