{{% notice tip %}}
The **pcluster ssh** is a wrapper around SSH. Depending on the case, you can also login to your head node using ssh and the public or private IP address.
{{% /notice %}}
You can list existing clusters using the following command. This is a convenient way to find the name of a cluster in case you forget it.
```bash
pcluster list-clusters
```
Now that your cluster has been created, login to the head node using the following command in your AWS Cloud9 terminal:
```bash
pcluster ssh --cluster-name hpc -i lab-your-key.pem
```
The EC2 instance asks for confirmation of the ssh login the first time you login to the instance. Type **yes**.
