# HPC Leasing

Tutorial on utilizing Digilab's HPC lease for training and other research compute necessities.

# 2. Connecting to the HPC

## Tailscale SSH Setup
Digilab uses Tailscale SSH to access its HPCs. 

### Installing Tailscale

Visit Tailscale's [installation page](https://tailscale.com/docs/install) and follow its instructions according to your device's operating system. 

> Further Tailscale commands on Linux devices might require you to sudo into your system.

Ensure that Tailscale is installed properly by running the following command on your terminal:
```
tailscale status
```

### Login into Tailscale
Run the following command to login into Tailscale CLI:
```
tailscale login
```

Visit the authentication link and login with Google `guest.digilabui @ gmail.com`. The password should be given by the HPC coordinator.

### SSH into The Machine
By now, the coordinator should have given you a username and a Tailscale name for the HPC. You can connect to the HPC by doing:
```
ssh USERNAME@TAILSCALE_NAME
```
