In order to do anything on the Shared Computing Cluster (SCC) from your local computer, you first need to connect to the SCC using an SSH (Secure SHell) client. This task varies greatly based on your local operating system; please select your operating system below for instructions.
There is also an alternate method to access the SCC using just your web browser. Simply go to http://scc-ondemand.bu.edu/ in your web browser. This does require using Duo Two-Factor Authentication. This will take you to SCC Open OnDemand, another way to use the SCC. Documentation on OnDemand is available.
There are four login nodes for the general Shared Computing Cluster. The fifth node below,
scc-lite.bu.edu, is intended to be used only by those with Linux Virtual Lab/scc-lite accounts.
|scc1.bu.edu||General purpose login node, accessible from the general internet.|
|scc2.bu.edu||General purpose login node, accessible from the general internet.|
|geo.bu.edu||Earth and Environment department node, accessible from the general internet.|
|scc4.bu.edu||BUMC node. Access to /restricted data partitions. Requires VPN or first logging in through another node, such as
|scc-lite.bu.edu||Linux Virtual Lab node for users of the scc-lite project. In following the instructions on these pages, these users should:
2) Ignore references to Project Disk Space such as
3) Ignore references to batch processing or compute nodes.

Connecting to the SCC from Microsoft Windows
There are multiple SSH clients available for Microsoft Windows, each will connect to the SCC using the same protocol. These instructions are based on MobaXterm because this application provides functionality you may find useful for other tasks; other application suggestions are below.
Using MobaXterm to Connect to the SCC
- Download and Install MobaXterm. You can also watch this MobaXterm Demonstration video.
- Launch MobaXterm and start a “New Session”:
- Select “SSH” as the session type:
- Specify “scc1.bu.edu” as the remote host and click “OK”:
- Your connection will be saved on the left sidebar, so the next time you can start your session by clicking the “scc1.bu.edu [SSH]” link. In the terminal window you will get a prompt to enter your BU login information and password (Note that the characters in your password will not be displayed when you type them as a security precaution):
Connecting to the SCC from Apple OS X
The Secure SHell (SSH) is built into the Apple OS X operating system. To connect to the SCC, we will leverage this utility using the Terminal application.
Using Terminal to Connect to the SCC
- Open the Terminal application, which is found in Applications >> Utilities >> Terminal. Alternatively, press <command> and <space> simultaneously to open Spotlight, search for Terminal and press <return>.
- In the terminal, type
- Enter your BU Kerberos password when requested. Note that the characters in your password will not be displayed when you type them as a security precaution.
exitin the terminal when you are done working on the SCC.
Connecting to the SCC from Linux
The Secure SHell (SSH) is built into the Linux operating system. To connect to the SCC, we will leverage this utility using the Terminal application.
Connecting to the SCC
- Open a Terminal. This can be done by opening the terminal application in Systems >> Accessories >> Terminal or by using the hot-key Ctrl + Alt + T
sshto connect to the SCC with your login credentials, using a command similar to this example:
your_local_machine% ssh yourBULoginName@scc1.bu.edu
- Enter your BU Kerberos password when prompted. Note that the characters in your password will not be displayed when you type them as a security precaution.
- When finished, type
exitto close the session.
