Using NX for GUI access to NBER computers

Full screen access to the NBER servers is via X-Windows, using either a standard X-server, or the newer NX protocol, which offers better performance. These instructions have been tested with nomachine_4.0.360_1.exe. Our servers will also work with the OpenNX client.

Installing NX

  1. Do not do use the latest Nomachine (6.x) client - it does not work at NBER. Do this ==> Download and install older Nomachine 5.1.26 client from:
    Windows Client:
    MacOS Client:
  2. Start up nomachine (nomachine...exe) and read and click through the boilerplate. Restart your computer.
  3. Login and select the Red NoMachine icon on the desktop. Read and click through the tutorial instructions.
  4. You will be put on a page of Recent connections (obviously there are no recent connectsion yet). Select "New" to add an NBER server such as "" as a host computer.
  5. Now you are in the "Create a connection" window. For "Name" enter a name you want the connection to be named, e.g. "nber4" Select the drop down for Protocol to pick "ssh" (not NX). Continue (blue box at right bottom).
  6. For "Host" enter an NBER computer hostname, e.g. "". Check that the Port is "22". If not, use the back button. Continue.
  7. Use Nomachine login (not the default). Continue.
  8. Continue past alternate server key without an entry.
  9. Don't use a proxy (default). Continue.
  10. Put a name such as "nber4" in the text box. Optionally check the "Create a link on the desktop". Done.
  11. Now you can click on the "Recent Connections" window to connect to the server. Continue.
  12. Verify host authenticity. Yes.
  13. Enter your login and password. Do not save the password. Continue
  14. Select "Create a new GNOME virtual desktop" (the first available icon).
  15. OK OK OK
  16. Now you are logged in. Use "Applications|System Tools|Terminal" to get a terminal window.
  17. Select the red X and "terminate" to log out.

These settings are saved, so you do not have to go over them again. To log in, select the red NoMachine icon on the desktop, and follow the prompts. You can add more servers with the "Configure" button on the login screen.


Does another NBER server work better? Otherwise, contact Mohan Ramanujan or other IT staff. You may need to remove the ".gconf" directory in your home directory to get a successful login.
