FastX 2
Stronghold tenants with Linux compute environments can access their environments using FastX 2. These sessions are persistent, which allows users to disconnect and resume them at another time and from different devices. CIS has configured a lightweight graphical panel for users to launch terminal sessions and other software packages.
Due to the highly sensitive nature of the data contained in Stronghold, CIS has taken measures to restrict the ability to accidentally or intentionally move data out of the environment. Direct SSH access is not enabled for end users, as there is no way to restrict copying and pasting the contents of a file from an SSH session. Copying and pasting from remote applications to local applications is also disabled (and vice versa). Here's how it works:
- 1.Connect to tenant via FastX 2
- 2.Start a session for your environment using FastX 2
- 3.Navigate your environment
NOTE: Users on campus must be connected to the Brown WiFi or a wired connection in a research building. Off-campus users can access their environments by connecting through the Brown VPN
Launch FastX 2.
In the FastX 2 connections window, click the
+ icon and select SSHComplete the SSH connection fields.
Replace
<tenant> with your assigned tenant and <username>with the username used to access Stronghold . The Name field can be filled in with any name you would like to call your session and Sci should be left blank.Click Save
- Name:
<name> - Host:
<tenant>.stronghold.brown.edu - Port:

<username> - Sci:
SSH Connection Window
Double click the connection entry you just created.
Enter your credentials and click
Continue
You will be prompted to select a Duo two-factor authentication method. Enter the number of your choice, and click
Continue
The first time you log in, you may see a window asking to confirm the authenticity of your environment. If this is your first time logging in, type “yes” in the text box and click
OK.After logging in, you’ll see the sessions window. If you had any running sessions, they would be listed here. Since this is your first time logging in, we’ll need to start a new session.
Click the
+ icon
Click “Stronghold” and “OK” to start the launcher panel.
A drop down menu of applications is found on the upper left hand side of the window
If you click the terminal icon from the drop down, you’ll open a new terminal window. In it, you can load software modules, Conda environments, and run other commands. Expect to do most of your work here.
Note: you can only run one Stronghold panel at a time. Launching an additional panel will automatically terminate any other running sessions.
To save and disconnect your session, click the “person” icon and select “Disconnect”, as shown in the picture below. The next time you log in you can resume your existing session by clicking the triangular “play” icon
If you already close the FastX window where you can launch applications and/or start a terminal, the 'Disconnect' option will be in gray. Then you can just close the window shown in the picture above.
If you do not exit/leave a FastX session correctly, you may not be able to reconnect your existing FastX session again.
