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> https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/msg)?

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.

Can you pls let me know if Restful APIs are available for this? 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? -Nick
