Using the NoMachine NX Client

Prerequisites:

Installation Instructions:

  1. Go to www.nomachine.com/download.php and choose the NX Client for Linux.
  2. Select the NX Client DEB for Linux based on the architecture of your computer (use "uname -m" in a terminal; i686 means you should download the i386 package )
  3. You will be prompted to open the package with GDebi Package Installer, click OK.
  4. Click Install Package, type in your password and the package will be installed

Launching the application:

  1. Select Applications->Internet->NX Client for Linux->NX Client for Linux


  2. Click Next on the initial NX Connection Wizard screen


  3. Enter "CSG Linux Desktop" for the Session field and "linux.divms.uiowa.edu" for the Host field and click Next.


  4. Change the pulldown from KDE to GNOME and click Next.


  5. Click Finish


  6. Enter your DIVMS username in the Login field , enter your DIVMS password in Password field, and then click Login.



     
  7. The first time you connect, you'll be asked to verify the key fingerprint of the NoMachine server.
    You are connecting to the correct server if the window shows this RSA fingerprint:
    45:61:23:71:74:9f:f7:fd:18:b9:5f:d2:c3:d5:71:b6.  If the fingerprint matches, click "Yes".



  8. You will be connected to a Linux desktop environment on one of the NoMachine servers in Mathematical Sciences. The NoMachine servers are a shared resource. Do NOT run computationally intensive programs on these servers.
     

Troubleshooting:

When logging in, I get a dialog box that says "Connection error." Why can't I connect?

The NoMachine servers allow 20 seconds to successfully authenticate. If you take too long clicking on dialogs the connection can timeout. Click "Close" on the dialog and try again. If you are still having issues, send an email to request@divms.uiowa.edu for help.

When I clicked on the NX Client DEB, the GDebi Package Installer didn't start. How do I install the package?

The download page for the DEB file has instructions on how to install. Generally, it will be 

sudo dpkg -i nxclient*.deb
