Hi all,
this is a rather strange problem, I hope the title is explicit enough.
Here is what happens chronologically :
1. I start various SSH connections to a host, some normal, some with X
forwarding, like that: "ssh user@host" and "ssh -X -n user@host GUI_APP"
(like firejail firefox, firejail thunderbird, etc). There's no user
connected under X yet, only the greeter is displayed.
2. using VNC or rdesktop, I then log on to X on the machine, do some
stuff, then hit "log off" from the desktop menu.
Immediately, ALL the previous SSH connections started in step 1 get
closed, hence all the shells and the GUI apps (firefox, etc) !
Everything is done using the same local and remote users (same UID but
different names). sshd is the parent process of all my remote SSH sessions.
I don't get how apps and shells NOT started via the X session, moreover
previously to its creation, are closed when the X session closes, what's
happening here ?!
As the outcome is the same with VNC and rdesktop, I guess the problem is
lying in the OS. Could it be related to logind ? Or an SSH(d) setting ?
Both systems are Debian 11/bullseye stable with X(org).
The client is running XFCE (but has MATE installed), the remote server
is only running MATE (no other DE installed).
It happens since at least a year.
Ideas anyone ?
Have a nice evening,
