Hi,

I am trying to use the demo at [GitHub - ubccr/hpc-toolset-tutorial: Tutorial for installing Open XDMoD, OnDemand, & ColdFront](https://github.com/ubccr/hpc-toolset-tutorial)

The problem is the machine I am running it on does not have browsers or graphical access (why don’t I run it on my desktop machine you ask? That is a whole other thing that I may post about later.).

So I can’t access these containers via `localhost` from my desktop machine. When I go to [https://the-hostname:3443](https://the-hostname:3443) it redirects to [https://localhost:3443](https://localhost:3443).

I exec’d into the ondemand container (which is the one I want to use in a demo) and edited `/etc/ood/config/ood_portal.yml` to change the servername from localhost to the FQDN of my host name. I then ran `/opt/ood/ood-portal-generator/sbin/update_ood_portal` which suggested restarting the web server with `sudo systemctl try-restart httpd24-httpd.service httpd24-htcacheclean.service` but that command gives me:

```nohighlight
Failed to get D-Bus connection: Operation not permitted

```

Some googling suggested that I needed to run the container with `privileged: true` but I added that to the `docker-compose.yml` and restarted the containers and I am getting the same error.

Any suggestions?  
Thanks

Yea I just went through a bunch of trouble with our own container. My guess is you need cgroup v2 enabled on your machine to be able to restart systemd in the container. But then again - I wonder why it was able to come up at all in the first place but then not be able to restart? When I was having issues it was just with bringing up systemd in the first place, no issues restarting it.

Thanks. I’m not sure how to enable cgroup v2 on this machine? It’s just an AWS EC2 instance running ubuntu 22.04 but it could really be any distro/version if that makes it easier…

It’s a boot parameter. I don’t know if you can edit ec2’s kernel boot parameters or not.
