This is my first OOD deployment. Alma Linux 8, OOD installed via RPMs (ondemand-2.0.28-1.el8.x86_64). I’ve got OOD allocating a slurm node and starting the desktop session (xfce4). I see the Xvnc server start, but noVNC fails to connect. I’m a bit out of my depth with this; not sure where to find the next step in getting this working. Here are the details…
Dev tools on the browser (Chrome) says:
WebSocket connection to ‘ws://linstattest.ssc.wisc.edu/rnode/linstattest.ssc.wisc.edu/44696/websockify’ failed:
open @ websock.js:185
rfb.js:255 WebSocket on-error event
(anonymous) @ rfb.js:255
rfb.js:721 Failed when connecting: Connection closed (code: 1006)
_fail @ rfb.js:721
The desktop config:
cat /etc/ood/config/apps/bc_desktop/slurm_desktop.yml
title: “Slurm Desktop”
cluster: “slurm”
attributes:
desktop: “xfce”
batch_connect:
template: vnc`
I’m not seeing anything particular in the user ouput.log…
