Ssh Connections Not Closing When Qt Application Is Opened?
https://bugzilla.redhat.com/show_bug.cgi?id86971
I have been able to reproduce the above issue on my home network and at work, but RedHat is claiming it is not a bug, so can some people on this list give it a try and see if they can reproduce it?
Thanks, Dave

I see this behaviour frequently with X11 over SSH tunnels, both from CentOS to CentOS and from OSX to CentOS. I cannot say with certainty which programs cause it, or even if said programs reliably cause the same behaviour every time, since my usual fix is to simplyC the SSH session after exiting. Next time it pops up I will note the circumstance and see if I can recreate the same behaviour.
gee, I wonder if this is the cause of an odd behavior I occasionally see: SSH from linux at work to my linux box at home (or between any two Linux boxes, actually). when I’m done I might enter ^D to close the remote terminal. Most of the time this terminates the remote session and returns to a local prompt. But sometimes the local session’s prompt does not reappear until I also do ^C.

If you connect with ‘-vvv’ you can see multiple x11 connections being open:
debug3: channel 1: status: The following connections are open:
#0 client-session (t4 r0 i0/0 o0/0 fd 4/5 cfd -1)
#1 x11 (t4 r2 i3/0 o3/0 fd 7/7 cfd -1)
#2 x11 (t4 r3 i0/0 o0/0 fd 8/8 cfd -1)
#3 x11 (t4 r4 i0/0 o0/0 fd 9/9 cfd -1)
The additional x11 connections are from automatically launched dbus stuff. On exit they don’t get closed, therefore the hang. This happens on C6 and C7 with GTK+ 2/3 or Qt4/5 but not with GTK+ 1, Qt3 or legacy apps and it’s nothing new. It just never gets fixed. (I think it’s a dbus bug.)
