The first step in accessing Bridges-2 is to request an XSEDE account.
First, head Head to the XSEDE User Portal.
In the upper left hand corner of the Portal, under 'Get Started on XSEDE', click 'Create an Account' if you are new to XSEDE, or, if you already have an account created, click on 'Sign In'.
...
The XSEDE's Single Sign On (SSO) login hub, login.xsede.org, is a single point-of-entry to the XSEDE cyberinfrastructure. Upon logging into the hub with your XSEDE User Portal (XUP) username and password, a 12 hour proxy certificate is automatically generated, allowing you to access XSEDE resources for the duration of the proxy. You may then gsissh to any XSEDE compute resource where you have an account without the need for a resource-specific username and password.
4. Use ssh to connect to Bridges-2 using XSEDE credentials and DUO MFA
Using your ssh client, use your XSEDE credentials and connect to hostname bridges2.psc.edu using port 2222.
ssh -p 2222 xsede-username@bridges2.psc.edu
Enter your XSEDE password when prompted.
If you are registered with XSEDE DUO, you will receive a prompt on your device. Once you have approved it, you will be logged in
You will be met with a similar output if the connection was successful:
[XUPusername@ssohub ~]$ gsissh bridges
