Accessing Vulcan
================

Accessing the Vulcan Big Data Cluster requires using a Secure Shell (SSH) client and having Booth credentials (i.e. Booth ID and password).

:Connection Type: ssh
:Host Name: vulcan.chicagobooth.edu
:Port Number: 22

Mac/Linux
---------

Mac and Linux systems have a built-in Terminal that can be used to access Mercury.
In these systems, simply open a Terminal window and type the SSH command at the prompt.

.. code-block:: console

    $ ssh <BoothID>@vulcan.chicagobooth.edu

At the prompt, enter your Booth password.
The screen will not show characters as you type your password.

.. note:: You must use your Booth ID, not CNET ID!

Windows
-------

Windows users will need to first download a terminal emulator.
PuTTY for Windows is one example of a terminal emulator that can be used as a Secure Shell (SSH) client.
The official PuTTY download page can be found `here`_.

.. _here: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

Once downloaded, a connection to Vulcan can be initiated by entering the host name, port number, and connection type.
