Description : An agent program for translating between amateur
radio installed programs and WebSockets
kel-agent An agent program for translating between various amateur radio
installed programs and WebSockets. This will allow the creation of
cloud-based amateur radio applications while using integration points
only available through local processes.
.
Architecture
.
At first this will support receiving status and log messages from
WSJT-X. Planned support includes rigctld and Ham Radio Deluxe for
transceiver remote control. Running on localhost In the simplest case,
kel-agent is running on the same computer as your radio programs and
browser. In this case, you can have kel-agent bind to localhost which
will only allow programs on the same computer to connect. This is
straightforward, safe and the default.
.
.
$ kel-agent 2020/10/10 18:50:32 kel-agent ready to serve at
ws://localhost:8081
.
Running on another machine If you want to run your radio programs
and kel-agent on one computer and your browser on another, this is
possible. There are a couple of approaches. Neither is super easy,
which I hope to fix.
.
NOTE: I do not recommend serving this in a way that's exposed to the
internet because there is no authentication. If exposed to the internet,
anyone could potentially initiate transmissions with your radio. SSH port
forwarding This method is relatively simple and quick to execute, but
is more brittle than serving secure websockets because there is some
setup each time you want to use the agent remotely, and conceptually
a little harder. Your remote machine must be running an SSH server for
this to work.
.
On the remote machine with your radio software, run kel-agent normally. It
can be bound to localhost.
.
.
$ kel-agent 2020/10/10 18:50:32 kel-agent ready to serve at
ws://localhost:8081
.
.
On the machine with your browser, start a command line and establish an
SSH tunnel with port forwarding:
.
.
$ ssh -N -L localhost:8081:localhost:8081 radio-pi
.
.
The first localhost:8081 means "on this (browser) machine, bind to port
8081 and only expose to localhost so other computers can't use it." The
second localhost:8081 means "once you log into the remote computer, start
forwarding traffic to port 8081 on its (remote) localhost." Finally,
radio-pi in my example is the remote hostname which is running kel-agent
and the SSH server.
.
The command will look like it's not doing anything; just let it run,
and the tunnel will stay open.
.
Now your web application can be configured to connect to
localhost. Traffic bound for localhost:8081 will get securely forwarded
to the remote machine. Both the browser and kel-agent think they're
talking to local processes, and you won't get mixed content warnings.
Secure Websocket with TLS This method needs a little more set up ahead
of time, but is easier to use once it's set up.
.
First, you'll need kel-agent to bind to 0.0.0.0 to allow connections
from other computers. Second, due to the mixed content policy which is
standard in web browsers, you'll need to specify a TLS certificate and
private key. Eventually I hope to make this easy, but for now you'll
need to follow https://stackoverflow.com/a/60516812/587091. In short,
• generate a CA key and root certificate, then• a server key and
certificate signing request with the server's hostname,• sign the
request to generate the server certificate, then finally• install the
root certificate in your browser's trusted authorities. Yeah, I really
need to make this easier.
.
.
$ kel-agent -host 0.0.0.0:8081 -key server.key -cert server.crt 2020/10/10
19:05:39 kel-agent ready to serve at wss://0.0.0.0:8081
.
.
Once running this way, your web application can be configured to
connect directly to the remote computer. Allowed origins As part of
the same-origin policy which is standard in web browsers, kel-agent
will only accept browser connections from certain origins (basically,
websites). By default, only the website https://log.k0swe.radio plus
some local developer addresses are allowed to connect to kel-agent,
but this can be customized if others develop web applications that use
kel-agent. I'm happy to accept pull requests to expand the default list!
.
.
$ kel-agent -origins "https://log.k0swe.radio,https://someother.nifty.app";
2020/10/10 19:18:52 Allowed origins are [https://log.k0swe.radio
https://someother.nifty.app]
