Establishing a VNC connection
We utilize a VNC server during analysis meetings to allow all remote parties to view a common computer desktop. It should be possible to connect to this session using one of the methods described below. If everything is working right, you'll see a web browser displaying the SANE homepage with which you can interact normally as in a standard web session. If you encounter any problems or need the password, please contact bhovik@jlab.org
Whatever platform you use to connect, please make sure to set the "shared" option in your vncviewer as described below.
From a Linux prompt
If at JLab, first set up a tunnel for VNC into JLab [Optional step if not at JLab]:
ssh -L 5927:twist.phys.virginia.edu:5927 sane@twist.phys.virginia.edu
Enter the password.
In another terminal window, start the viewer
vncviewer -shared localhost:5927 &
Enter the same password.
Nothing to show during the meeting? Please add the -viewonly flag. You will be able to observe but not control what is displayed, saves server load.
The vncviewer is standard on the CUE systems at JLab.
If you don't have the Linux vncviewer, you can download and install from Real VNC or Tight VNC
From Windows:
Download and install the viewer from Real VNC or Tight VNC
If at JLab, a tunnel needs to be set up with the putty terminal emulator, as explained here Putty Howto
From Mac OSX:
Download and install from Chicken of the VNC
If at JLab, a tunnel needs to be set up, as explained above for Linux
From Any Web Browser( easiest of all, a bit slower, great for viewing only)
If all else fails, vnc can be run from any standand web browser. To connect, just enter the following url on your LOCAL browser's address bar:
twist.phys.virginia.edu:5827
Under options, please select "Shared Desktop : YES"
If you have nothing to show during the meeting, please chose "View Only: YES". This will establish a session where you can observe but not control what is displayed.
Enter the password.
If at JLab, a tunnel needs to be set up, as explained above for Linux, but
- use port 5827 instead of 5927
- Enter localhost:5827 in your LOCAL browser's address bar
