I have an OOD implementation that works on one cluster/machine, but an identical installation on a different cluster/machine does not work.

Error from output.log that is different between the two:

```auto
dbus-update-activation-environment: warning: error sending to systemd: org.freedesktop.DBus.Error.Spawn.ChildExited: Process org.freedesktop.systemd1 exited with status 1

```

I’ve been chasing this issue for a couple days. A fresh XFCE, websockify, turbovnc, etc have all been installed, reinstalled, copied from the working implementation, nothing thus far has worked.

Surely i’m missing something simple, probably related to dbus or systemd. Anyone got ideas?

Yes it is definitely a systemd/dbus error. Do you see anything relevant in `journalctl` or similar?

Off the top of my head - I’d check to see if systemd started a dbus-deamon for you.

I just spot checked our systems and I see this in my `ps -elf` output. Note the user is `dbus` and the PID is 4 - so systemd (being PID 1) booted it up pretty early.

```auto
4 S dbus 2682 1 0 80 0 - 20660 ep_pol Mar31 ? 00:20:40 /usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation

```

Other things I’d ask are if you had to set/reset any `XDG` related environment variables on the other cluster. For example, OSC sets `XDG_RUNTIME_DIR` for desktops in their `submit.yml.erb`.

```

Nothing notable in journalctl. the dbus-daemon starts, and shows

```auto
May 03 14:37:18 atlas-0022 dbus-daemon[95024]: [session uid=1727050709 pid=95022] Activating service name='org.freedesktop.systemd1' requested by ':1.5' (uid=1727050709 pid=95047 comm="dbus-update-activation-environment --systemd SSH_A" >

```

Which is basically the same as the output.log error.

and in template/desktop/xfce.sh

```auto
export XDG_CONFIG_DIRS="/apps/other/ood-depends/xfce-4.18.0/etc:$XDG_CONFIG_DIRS"

```

and that folder exists:

I see `dbus-daemon`’s launched by you, but I don’t see them launched by `dbus`. I found our systemd service file here - `/usr/lib/systemd/system/dbus.service`. I don’t know if you have the similar service enabled. I’d ask to check the working cluster to see if you can find the `dbus-daemon` launched by systemd on it.

You’re requesting a display on the 5th screen here. This could be a red-herring, but I feel like like a headless compute node likely does not have 5 or more screens. I’m trying to figure out how screens are defined in Xorg, but I suspect this is somehow off, though it may or may not be the actual issue.

`xrandr` can tell you how many screens you have - though I’m still looking for my `Xorg.conf` file, I believe they’re defined in that file.

It’s almost like websockify isn’t quite firing up. But if i peek the websockify log on both

Working

```auto
WebSocket server settings:
  - Listen on :11059
  - No SSL/TLS support (no cert file)
  - proxying from :11059 to localhost:5901
130.18.14.159 - - [03/May/2024 15:14:44] 130.18.14.159: Plain non-SSL (ws://) WebSocket connection
130.18.14.159 - - [03/May/2024 15:14:44] 130.18.14.159: Path: '/websockify'
130.18.14.159 - - [03/May/2024 15:14:44] connecting to: localhost:5901

```

non-working

```auto
WebSocket server settings:
  - Listen on :8163
  - No SSL/TLS support (no cert file)
  - proxying from :8163 to localhost:5901

```

So is the issue related to websockify not forwarding correctly?

this is also supported by a duplicate jupyter application, that works on the working cluster, but throws “URL not found” on the non-working cluster.

I also think the display number is a red herring, but i could be convinced otherwise.

ignore that psg compare. If you put a dot in your grep and don’t think about it too much, it gets the wrong list of what’s running.

What is your OS and version? I’m surprised you don’t have a `dbus.service` - what you’re showing is `dbus-broker` which could be different? Though it doesn’t appear to be on the system that’s working, so maybe that’s a red herring too…

IDK about your Jupyter issues - but Juypter is web application so there’s no X11/VNC/dbus involved with that application.

OS = Rocky-9.1

Checking reverse proxy stuff, based on websockify not connecting, and jupyter not connecting:

```auto
nc -l 5432

```

This address generates stuff

```auto
https://atlas-ood.hpc.msstate.edu/node/atlas-0022.hpc.msstate.edu/5432

```

This one doesn’t

```auto
https://atlas-ood.hpc.msstate.edu/node/atlas-0022/5432

```

This was the right place to look. my OOD Portal file did not match the cluster file. The portal file had the fqdn in the regex, but the hosts were using their short names:

```auto
host=$(hostname | awk -F. '{print $1}' | tr A-Z a-z )

```

🤦🏼

That fixed desktop and jupyter, but not rstudio

```auto
xfsettingsd: No window manager registered on screen 0.

(xfsettingsd:105274): xfsettingsd-WARNING **: 15:48:12.474: Failed to get the _NET_NUMBER_OF_DESKTOPS property.

```

Any parallel thoughts with the displays herring?

rstudio is also a web application (which doesn’t require X11/VNC/dbus) - unless you’re running the other variant which I can’t remember of the top of my head.

We are running the other version, I believe:

No, but googling that seems to indicate that XFCE is responding to files in your `~/.cache/sessions` so maybe it’s worth a shot to remove/backup things in your home directories.

removed, cache, still catching the same error:

```auto

Almost as if the display isn’t getting assigned.
