The browser sends a hello message anytime the user switches to the
sessions page, upon which the server sends the current state back.
THis also improves the timeout handling of broken connecions.

2024-08-01 20:53:52 +02:00

Now by default wsproxy uses a specific protocol to establish connections to the server. It does this by adding the ?wsproxy query parameter.
...
The server then sends it the protocol version and the client connection info describing whether an agent was found or not. This improves usability for users.
With the --raw option it bypasses this query parameter and wsproxy then works in the old way as a simple stdio-websocket connector. It then still works with converge server but can also be used for simple websocket troubleshooting.

Added pprof to convergeserver and optionally to
...
the agent if PPROF_PORT is set.
Fixed issue with converge server not cleaning up goroutines because of blocking channel. Made sure to create channels with > 1 size everywhere it can be done. The blocking behavior of a default channel size is mostly in the way.
Known issue: Killing the SSH client will lead to the server side process not being terminated and some goroutines still running in the agent. This would require additional investigation to solve. The remote processes are still being cleaned up ok (at least on linux) when the agent exits.
This should not be an issue at all since the agent is a short-lived process and when running in a containerized environment with containers running on demand the cleanup will definitely work.
2024-07-28 11:48:31 +02:00

621bbd8ca6
GOB channel for easily and asynchronously using GOB on a single network connection, also dealing with timeouts and errors in a good way.
...
Protocol version is now checked when the agent connects to the converge server.
Next up: sending connection metadata and username password from server to agent and sending environment information back to the server. This means then that the side channel will only be used for expiry time messages and session type with the client id passed in so the converge server can than correlate the results back to the correct channel.
2024-07-27 11:21:35 +02:00
f82601d07c
Lots of refactoring.

Now hijacking the ssh connection setup in the listener to exchange some information before passing the connection on to the SSH server.
Next step is to do the full exchange of required information and to make it easy some simple Read and Write methods with timeouts are needed that use gob.
