Connecting to SCRC Computers


Logging In

You connect to the SCRC computing environment using a command line interface program.


Windows

PuTTY is free and can be downloaded from PuTTY Download.  Download and save “putty.exe” on your desktop.

Start PuTTY, then type rnd.stern.nyu.edu or vleda.stern.nyu.edu in the “Host Name” field and click “Open”.  (Note: The first time you log in a dialog may appear which starts with “The server’s host key is not cached…”.  Click Yes in this dialog.)  Type your Stern NetID and password at the “login as” and “password” prompts, respectively.

You should now be logged in and see a command line prompt from which you can enter Linux commands or run programs. For help with Linux see Linux Basics or www.linux.org/forums/beginner-tutorials. For help running programs on the Stern GRID see GRID Processing at Stern.

Xming enables graphical windowing capabilities with PuTTY on the SCRC Linux computers for programs such as gvim, emacs, matlab, SAS, and Stata.

Download and install both Xming and Xming-fonts from here: sourceforge.net/projects/xming/files. In order for Xming to run correctly, it must be restarted after installing the Xming-fonts. Exit Xming, i.e., right-click its icon in the bottom right task bar and select “Exit”, after which you must restart Xming. Xming runs transparently.  You can see the Xming process in the task manager and as an icon in the taskbar but it does not itself have a window.

Now configure PuTTY by navigating the tree in the left side of the PuTTY window: Connection → SSH → X11, then check the box “Enable X11 forwarding”. To save this configuration, click “Session”, then enter a name in the “Saved Sessions” text box and click “Save”. The next time you want to connect, click on your saved session name from the “Saved Sessions” list and click “Load” then “Open”.


Mac OS X

Use the Terminal program that is included in the OS X operating system on a Mac. You can find the Terminal program by using Spotlight, i.e., click the magnifying glass in the upper right corner and type “Terminal”. At the Terminal prompt type ssh -Y yourSternNetID@rnd.stern.nyu.edu or ssh -Y yourSternNetID@vleda.stern.nyu.edu and when prompted, enter your Stern password.

You should now be logged in and see a command line prompt from which you can enter Linux commands or run programs. For help with Linux see Linux Basics or www.linux.org/forums/beginner-tutorials. For help running programs on the Stern GRID see GRID Processing at Stern.

Graphical windowing capabilities are enabled for programs such as gvim, emacs, matlab, SAS, and Stata.


Transferring Files To/From the SCRC Linux Computers

filezilla is a free stand alone program to transfer files between your PC or Mac and the SCRC Linux Computers. Download the program here: filezilla-project.org.

To start a session, type rnd.stern.nyu.edu or vleda.stern.nyu.edu into the “Host” field, your Stern netID into the “Username” field, your Stern password into the “Password” field, and 22 into the “Port” field then click Quickconnect.

The left pane shows your local files and directories and the right pane shows your home directory and files on the remote SCRC Linux system.  You can use the drag and drop feature to transfer files in either direction. Note: Your Linux home directory has a 10 GB quota. If you need more than 10 GB of file space, please contact the Stern IT helpdesk and request a ticket be created and assigned to Research Computing.
