Dear group,
1. My workstation "gar" is running Debian 12 with XFCE.
2. I have another PC "marlin" running Ubuntu 24.04 LTS with XFCE.
3. I recently added a PC "octopus" running Ubuntu 26.04 LTS Server,
without desktop environment.
4. Both "marlin" and "octopus" have a user "localadmin", on "gar" my
username is "cgelinek".
5. I'd like to `ssh -Y localadmin@octopus` from "gar" and then start a
podman container with `xeyes` in it and be able to see it on my screen
on "gar".
6. I can do that with "marlin" (i.e. `ssh -Y localadmin@marlin`), but
not with "octopus".
Some debugging suggests that when I `ssh -Y localadmin@octopus`, on
octopus
* $DISPLAY is localhost:10.0,
* /home/localadmin/.Xauthority has the date of connection but
* $XAUTHORITY is empty.
* Unsurprisingly, when I try to run `xeyes` from within a container
(with DISPLAY and XAUTHORITY being forwarded), it stops with `Error:
Can't open display: localhost:10.0`.
I have checked that xauth is installed on octopus and have run out of
ideas what to try next, any ideas?
Thanks for your time,
Christian
I don't know what a podman container is.
You can export X from marlin but not from octopus?
I'd compare the sshd config file on octopus with the one on marlin
