It is more likely that you or someone had edited /etc/ssh/ssh_config to change ForwardX11Trusted or ForwardX11Timeout, and the Sierra upgrade overwrote it with a new default. -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com ballb...@sinenomine.net unix, openafs, kerberos, infrastructure, xmonadhttp://sinenomine.net ___ Do not post admin requests to the list.

Re: Intermittent Display Not Found Error After Sierra Upgrade
It's definitely client side. I logged into the same server on a Snow Leopard machine and did not have the same problem. I looked at my /etc/ssh directory and no modifications were made there since 2015, so it doesn't seem that Sierra overwrote anything. What I think happened is that the defaults in the binary for ssh have changed in Sierra. One way to verify that for sure would be to try logging in from a Yosemite VM; or is there perhaps a way to make ssh show it's build defaults? For now I've set ForwardX11Trusted to Yes and will see how it goes.

It's actually the client end doing this (since the client has the X server being forwarded) so I can't see it being based on a change to the server config. You would need to run ssh (not sshd) with -vvv and watch for a message in response to trying to run a new client: Rejected X11 connection after ForwardX11Timeout expired -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com ballb...@sinenomine.net unix, openafs, kerberos, infrastructure, xmonadhttp://sinenomine.net ___ Do not post admin requests to the list.

Are there any log files that I could look at (on either end) to help me verify whether this is indeed the problem?

Re: Intermittent Display Not Found Error After Sierra Upgrade
This just happened. I have two apps open. Both are running and functioning normally. I go to open a third. I get the display not found error. I open a new SSH session *without* closing the old one. The apps keep running, and I am able to open the third app in the new SSH session. I close the new SSH session and go back to the old one. When I attempt to launch an app I still get the display not found error.

Re: Intermittent Display Not Found Error After Sierra Upgrade
I don't think that is it. Today I had one app open and then tried to launch another. The former app kept running, but the console spit back a display cannot be found error when I attempted to launch the second. I closed the first app and attempted to relaunch it -- but it wouldn't. I killed the ssh session and opened another one, and then launched both apps with no problem.

Intermittent Display Not Found Error After Sierra Upgrade
Hi, Since upgrading to Sierra the other day I randomly get errors about the display not being found when launching apps from a Linux machine. When I logout and log back in to the remote machine things work again, but then after some time the problem reappears. Is this a known issue? Haroon ___ Do not post admin requests to the list.
