# Workbench pre-flight check

Follow the instructions below to install and run the pre-flight script. Run it on **each node in the system on which you plan to install Data Science & AI Workbench**, to verify that it meets the minimum requirements to install successfully.

**To install the package from Git**, run the following commands from a terminal on the node you’re checking:

```
git clone https://github.com/Anaconda-Platform/ae-preflight.git
cd ae-preflight
python setup.py install
```

**To install the package in an existing conda environment,** run the following command from a terminal on the node you’re checking:

```
conda install -c ae5-admin ae_preflight
```

**To run the profiler**, run the following command:

```
ae-preflight
```

Optionally append the command with any of these options, based on your preferences:

```
-i, --interface     Interface name (e.g., eth0 or ens3) to check for open ports
-v, --verbose       Increase verbosity of the script
--hostname          Check hostname to ensure that DNS can be resolved for TLD and wildcard DNS
```

System-specific instructions are also provided below.

The output of running the script is captured in a `results.txt` file.

**To view the results**, locate the `results.txt` file that was created in the directory that you ran the script from.

This file will contain warnings and notify you of any pre-flight checks that may have failed.
It will also describe the reason why a test failed, and provide a solution for fixing the issue.
