activating a route rule on a linux X11 machine breaks Desktop remote control about meshcentral-routeplus

[ryanblenis]

Interesting, what distro are you using so I can build a test VM for this case?

[guerby]

debian 10.3 with /etc/gdm3/daemon.conf

[daemon]
# Uncomment the line below to force the login screen to use Xorg
WaylandEnable=false

Same system than for this bug report :

Ylianst/MeshCentral#1287

gdm3 is running X but the meshagent doesn't seem to be able to pick up the login screen

Thanks!

@ryanblenis I know how to recompile the linux meshagent if needed

[guerby]

And of I forgot : the machine was running a GNOME/X11 session of a logged in user.

[ryanblenis]

Thanks, I'll install a VM with Debian 10.3 on it and give it a test. The plugin doesn't require a recompile of the MeshAgent (it's all in the MeshCore / aka Javascript). If it did require a recompile we'd likely be involving Brian from the MeshAgent project because it would be a root cause of the agent functionality itself, and not the plugin.

Ok, so I

1. installed a fresh copy from https://cdimage.debian.org/debian-cd/current/amd64/bt-cd/debian-10.3.0-amd64-netinst.iso.torrent ran the default install
2. set WaylandEnable=false in /etc/gdm3/daemon.conf
3. Rebooted, installed MeshAgent (left logged into X session as user for the remainder of the test)
4. Set the debian PC as "My Computer" in RoutePlus
5. Added a route to another node
6. Was still able to remote desktop in via MeshCentral without issue.

Just want to make sure those are the repeatable steps to take to try to reproduce the issue... because I'm not seeing it on my end. Let me know if I missed something.

I tried again (cleanup/reboot/reinstall) and I got sometimes Desktop working and sometimes not but not depending on RoutePlus additions as for my first tests.

In the webagent console after my experiments I noticed ("versions" I explicitely typed it):

(long list of the last one if I go back to Desktop and do something)

For reference I have 3 plugins installed enabled in meshcentral Event Log 0.0.23, Script Task 0.0.15 and RoutePlus 0.1.3.

I will probably reinstall the server and all the agents in the next few days, feel free to close if you don't think issues are related to routeplus.

Sorry for the noise.

[ryanblenis]

Sorry, just want to confirm (probably a language gap with me reading your last comment) that you tested without plugins and have the same issues. In that case, we can close this as it is more than likely unrelated to the plugin.
