## Troubleshooting Slurm Jobs

If you want to report a problem or request for help when running jobs, please
**always provide** the following information:

1. Provide your batch script or, alternatively, the path to your batch script.
2. Add **always** the following commands to your batch script

    ```bash
    echo "User information:"; who am i
    echo "Running hostname:"; hostname
    echo "Current location:"; pwd
    echo "User environment:"; env
    echo "List of PModules:"; module list
    ```

3. Whenever possible, provide the Slurm JobID.

Providing this information is **extremely important** in order to ease
debugging, otherwise only with the description of the issue or just the error
message is completely insufficient in most cases.

## Troubleshooting SSH

Use the ssh command with the "-vvv" option and copy and paste the text
(**please don't send us screenshots**) the output to your request in
Service-Now. Example:

```bash
ssh -Y -vvv $username@<hostname>
```
