Hi,
We have a custom guacamole client for a web application based on
guacamole-common-js and we are using the guacamole-lite NodeJS library as
“gateway” to guacd.
I’m currently implementing an auto-reconnect functionality in our app, because
we have to deal with random disconnects in the future.
I would like to implement a version that auto-reconnects as seamless as
possible to work around short connection issues (such as Kubernetes Nginx
Ingress reloads, which kill websockets).
I’m currently re-initializing the common-js Guacamole.Client on tunnel
disconnects and re-attaching the websocket to the existing guacamole-lite
session, which keeps the connection to guacd open in the meantime. From guacd’s
perspective, the session was never disconnected. This works fine so far.
I just can’t get the audio channels to work again. My client is subscribing to
Guacamole.Client.onaudio(), which is of course not triggered with my described
behaviour, since guacd doesn’t know about the lost session.
I tried the following things after a reconnect:
* Sending a “select” command with the guacd session ID followed by a new
handshake upon reconnect
* Guacd in DEBUG says: Handler not found for “select” followed by
“handler not found” for all the other handshake instructions I’m sending
* Do I have to tell guacd something before initializing a new “select”
command?
* Sending an “audio” command
* have the problem that the buffer handling in guacamole-lite is
creating trouble for me (so nothing to help for you here)
* The mimetype value seems to get mixed up with other messages, so I
need to investigate that further
* I just wanted to ask: Will guacd respond with a new audio output
stream anytime when a correct “audio” command arrives?
Thanks, and best regards
Benjamin
