Pushing message to VM using Guacamole API
Hi,
I want to push notification messages in end user VM similar like Guacamole slow or unstable network messages.
Can you pls let me know if Restful APIs are available for this?
Regards,
Umesh

The way I read Umesh's question is not to send out-of-band to admin
console, but messaging within the guac client itself. For example, say
multiple users are connected to the same remote session. A side pane would
allow them to facilitate a chat.
My example from a previous post was around session sharing. As an admin I
can jump into any active session without the session owner's permission.
Would prompting the session owner to allow admin to jump into user's
session be a guac protocol or a webserver implementation?

we do something like this out provisioner.
1. When the connections is created set the flags on the access time for that
connection on Guacamole, (database entry read)
2. When time is getting close, you can use the event handler to send an SSH
for VMware/Xen/KVM or a .net call for Microsoft, then send the message
directly to the VM (vm tools need to be installed) by injecting parameters.
Other option are iframe guacamole and use java script to get the time left,
note, guacamoles Kryptonite is iframes for keyboard mouse events loosing
focus.
3. Is to use the native Guacamole messaging to popup a warning, using event
call. So there are ways of doing this.

Is there some reason you need to push the messages to the VM rather than
displaying them in the Guacamole UI? You mentioned the way network
connectivity is displayed in Guacamole - couldn't you just push the
notification in the Guacamole UI?

Is this windows, linux, mac os? If windows, what about the windows msg command (https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/msg)?

Betreff: RE: Pushing message to VM using Guacamole API
Hi,
Thanks for response.
We are using Guacamole for Cloud labs. We are giving labs for say 30 hours for a month. Now when user is close to 30 hours, we want to send a notification to learner so that they can request for extension.
Or when we want to reboot the Lab due to patch or something else we can send a reboot notification so that they can save their data.
If Guacamole allows us to push notification from outside that will be great.

Umesh

There is no current implementation for sending "out-of-band" messages like this from the Guacamole system to the remote server.
The Guacamole protocol itself could easily support such a feature, it would just need to be implemented as a channel within Guacamole. However, the ability to implement it for the remote server(s) would depend upon the protocol you're using and its ability to support such "out-of-band" messages on the remote system - things that are not normal Keyboard/Mouse/Video messages. SSH can probably do this in some form or fashion. RDP has support for implementing arbitrary data channels, so it should be possible, there, as well. VNC probably would not support it, and neither would Telnet. Also, the ability for the remote system to do something with the messages would also require something listening on the remote system for the messages - an agent of some sort - that is able to receive the out-of-band messages and do something with them - display a message to the user, etc.
Can you describe your use-case a little bit more - what messages you'd want to send back to the remote system, and why you'd need to send and/or display them on the remote system?
