It is the entire file; it was generated using the Ansible vars that I included. I will attach the files tomorrow, for better context.

**Update** : Attaching the file and some more information.

[ood.yml](https://discourse.openondemand.org/uploads/short-url/y3pGfL98fRfmeQsdEtx5cFk5zIK.yml) (3.6 KB)

After manually modifying the file as seen [here](https://discourse.openondemand.org/t/linux-host-adapter-errors/886/3) I do not see the “undefined method” issue, however I see that it is trying to connect using Slurm.

Logs **/var/log/ondemand-nginx/bcasano/error.log**

```shell

```

Reviewing the session output logs **/cluster/home/bcasano/ondemand/data/sys/dashboard/batch\_connect/sys/bc\_desktop/tenanta/output/79d6b124-9a6c-43d6-b81f-4f52ccb1b740** I see the job is trying to connect to a different host.

**connection.yml**

```yaml
host: compute-tenanta-01
port: 5902
password: SOMEPASSWORD
display: 2
websocket: 21984
spassword: SOMEOTHERPASSWORD

```

**output.log**

```shell

```

The `line 7: module: command not found` error seems to be because it’s running the default script from `/var/www/ood/apps/sys/bc_desktop/template/script.sh.erb`.

Just in case, I removed `slurm-client` package from the host but I’m still seeing the same behavior.

Please, let me know if you need any other logs or something. I get the impression this might be a problem with my Ansible YAML configurations but I’m unable to see it.
