Access the VNC server from your MacOS computer

On your Mac OS-X computer we will use TigerVNC to connect to the VNC server running on the spectrometer computer.

If you don’t have it already, download and install TigerVNC:

• Navigate to: http://tigervnc.bphinz.com/nightly/
• Scroll down to the Mac OS-X section and download latest version of TigerVNC
• Install TigerVNC on your Mac OS-X computer

Open a terminal window: Launchpad > Other > Terminal

In the terminal window:

• Navigate to the Mac OS-X subfolder of TigerVNC:

cd /Applications/TigerVNC\ Viewer\ 1.XX.XX.app/Contents/MacOS

• Replace 1.XX.XX.app with the installed version of TigerVNC (e.g. 1.10.80.app)

• Start the program “TigerVNC Viewer” with the ‘-via’ option to tunnel through gw1 (or gw2):

./TigerVNC\ Viewer -via NetID@gw1.nmrfam.wisc.edu fleckvieh.nmrfam.wisc.edu:1

• Replace NetID with your NetID username
• Enter the NMRFAM spectrometer computer and VNC session number started in step 1 above (e.g. fleckvieh.nmrfam.wisc.edu:1)
• If the terminal does not immediately prompt you for a password, click the TigerVNC Viewer app logo in your toolbar. This should cause the terminal to ask for your password.
• You will be prompted (in the terminal) to enter your NetID password
• The next password requested (in a pop-up window) is the VNC password (provided by a staff member)

• A new window will appear with the desktop from the spectrometer computer.

NOTE: expanding this window to full screen is sometimes required to ensure that the position of the mouse pointer matches the screen coordinates clicked.
