3c803d6125 removed password based access
authorized keys can now be modified within the session.
keep last set of keys when no valid keys were found and keys are changed during the session .

b875540d6b Preparation for alternative context path.
The contextpath parameter in converge.go is
temporary and should be removed later. What is needed is autodetectio of the context path for the usage page and passing on the context for rendering.

21463a5cad * session will now expire some time after last user
activity and updated documentation.
* downloads will now download again. Because of hx-boost

367043e0c5 When a duplicate id is requested the server now allocates a new unique id so that the session can be handled anyway. 2024-07-30 19:45:25 +02:00
bf5120aa5b refactoring towards being able to send events from Admin to UI (websocket) without exposing connection info but only metadata. 2024-07-30 19:03:21 +02:00
39cf088a41 basic htmx with server sending content to the client over a websocket is now working. This only worked when text message where being sent so the websocket handling had to be made configurable with a 'text' boolean field. 2024-07-29 23:56:44 +02:00
d17ad9bc3e 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.

7a51e3ac45 Unique ids for clients generated by converge server and made available to the ssh session through a net.Conn extension that passes the ID to the SSH session through the LocalAddr(). 2024-07-27 22:37:40 +02:00
5a492f3855 initialization of username, password on client (from server) and initialization of agentinfo on server is now done as soon as the agent registered and not through a side channel.
Making use of some simple utilities for GOB to make it easy to send objects over the line.
2024-07-27 20:46:53 +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.
