d109c72f66 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 .

1b1f8f2167 A lot of work in getting cut and paste from the UI to
work properly.

Wrote two web components. One for cut and paste in general, and another for code samples.
2024-09-08 11:16:49 +02:00
51be117200 Simple validation of the id and the authorized keys. 2024-09-08 11:16:49 +02:00
2cf73feef5 More clean handling of the contextpath.
Now using long option names for the options of converge to be consistent with the other components.
2024-09-08 11:16:49 +02:00
75e1bd77ba Alternative contextpath is now supported.
This will simplify hosting in cases where you have no control over DNS but only over one domain.
2024-09-08 11:16:49 +02:00
9456665a6f 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.
2024-09-08 11:16:49 +02:00
b41317c598 Lots of work on making easier interactive documentation, especially to make working with SSH public keys really easy.
Next step is to do more validation in the UI.
Specifically:
* validate authorized keys
* detection of accidental use of a private key

Then, password based access can be disabled.
2024-09-08 11:16:49 +02:00
49db7578a7 large parts of the usage is now dynamic.
Still need to generate instructions for authorized keys. A lot of troubleshooting for the form to cookie persistence.
2024-09-08 11:16:49 +02:00
62b51a6d09 work in progress:
* usage page now has more dynamic part where user
  can enter id and publis ssh keys and the server will
  generate the appropriate commmands to execute depending on the local and remote shell.

830594740b * session will now expire some time after last user
activity and updated documentation.
* downloads will now download again. Because of hx-boost
  the downloads where rendered in the browser. Now
  disabling hx-boost for the downloads section.
* relative link for sessions page
2024-09-08 11:16:49 +02:00
a9bd539175 Updated documentation:
* remote shell usage for linux, cmd, and powershell
* help of wsproxy.
2024-09-08 11:16:49 +02:00
adee89cc08 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.

e141007f0a Now displaying agent number instead of id.
Passing timezone to server side for rendering of time stamps
Configuration of preferred shells.
2024-09-08 11:16:49 +02:00
d6fc2e4118 Rendering status as HTML tables. 2024-09-08 11:16:49 +02:00
638dffd143 doing the same thing as before but now rendering the
status using a template.

882f97fa17 many small changes
* removed the Async utility
* now using Ping message to webclient for keep alive instaed of actual content
* added remote shell to AgentInfo
* retry of connections to the agent
* better logging for SynchronizeStreams
2024-09-08 11:16:49 +02:00
9d460b9cf3 usage fix (agent was renamed by intellij to session)
Now using embedded timezone database by go so setting the TZ variable will work.
2024-09-08 11:16:49 +02:00
d6d2d5648c Live updates of the sessions.
V1 in ascii-art. To be improved.

100771a7ba restructuring 2024-09-08 11:16:49 +02:00
60d641a1a4 When a duplicate id is requested the server now allocates a new unique id so that the session can be handled anyway. 2024-09-08 11:16:49 +02:00
816e8d8609 refactoring towards being able to send events from Admin to UI (websocket) without exposing connection info but only metadata. 2024-09-08 11:16:49 +02:00
0e8ed86be3 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. 2024-09-08 11:16:49 +02:00
f6ea7a56a9 tabbed interface. 2024-09-08 11:16:49 +02:00

80a536c70e docs page now working again. 2024-09-08 11:16:49 +02:00

fcfe8a6637 Split up the main page into different parts. 2024-09-08 11:16:49 +02:00
4b05d7e8d8 Now rendering the index.html using the Templ library.
This is in preparation for:
1. creating a base page
2. using tabs: Home, Using, Downloads, Status
3. htmx

e01a2bc729 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.

788050df32 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(). 2024-09-08 11:16:49 +02:00
9d0675b2f2 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.
2024-09-08 11:16:49 +02:00
ada34495ef 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.
2024-09-08 11:16:49 +02:00
d3cbf8388f 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.
2024-09-08 11:16:49 +02:00
4d660a6805 Updated deployment with username and password settings.
index.html template now also uses the configured password.
2024-09-08 11:16:49 +02:00

d839583f7b communication between agent and server. Removed the flags libray for command-line parsing.
Heartbeat mechanism from client to server over the custom connection for sending events to guarantee that the connectoin stays up.
2024-09-08 11:16:48 +02:00
40e8d56429 removed read and write dead lines. Appears to be still working. 2024-09-08 11:16:48 +02:00
