To access CADES resources, you must connect with a Secure Shell client. In MacOS and most Linux distributions, a ssh client is built-in to the operating system. On Windows, PuTTY and MobaXterm can be used to provide ssh capability. Recent updates to Windows 10 have added built-in support for ssh. If it is not installed on your version of Windows, please refer to Microsoft’s documentation on OpenSSH. It can then be accessed with the Command Prompt or Windows PowerShell in the same way you would access ssh from a terminal within MacOS or Linux.
1. Log in to or-slurm-login01.ornl.gov
ssh username@or-slurm-login01.ornl.gov
2. Log in to or-condo-login02.ornl.gov
3.
ssh usrname@or-condo-login02.ornl.gov
X11 Forwarding
CADES resources support X11 forwarding, which enables the use of graphical tools. To use X11 forwarding, download an X11 terminal. On most Linux distros, xterm is built-in to the operating system. On MacOS, the XQuartz system handles X11 forwarding. You can access XQuartz by typing xterm in a standard Terminal. On Windows, PuTTY with xming support can be used to provide X11 forwarding.
Once you select an X11 terminal and open it, execute the ssh -X Username@or-slurm-login01.ornl.gov command at the prompt. If the connection does not work, replace -X with -Y. Because the option is case-sensitive, make sure you use capital letters. Upon connecting to the CADES, type xeyes or xclock to verify that the X11 system is functional.
3. Log in to CADES resources with X11 forwarding enabled
ssh -X usrname@or-condo-login02.ornl.gov
ssh -X username@or-slurm-login01.ornl.gov
