FarmVNC
This page documents a new script - farmvnc - which has been introduced with the upgrade to Ubuntu 13.04. The steps involved in setting up VNC on Farmshare are largely the same with just the change of substituting farmvnc script instead of vncserver.
running farmvnc
First, run farmvnc to see what resolution's are supported:
$ module load farmvnc $ farmvnc please give desired resolution on command line: for example: farmvnc 1440x900 you can choose any of the following 1024x768 1280x1024 1440x900 1920x1080
I am using a macbook air so I will choose 1440x900 so that full screen vnc will match with native mac resolution.
$ module load farmvnc $ farmvnc 1440x900 using display 1 Initializing built-in extension Generic Event Extension Initializing built-in extension SHAPE Initializing built-in extension MIT-SHM Initializing built-in extension XInputExtension Initializing built-in extension XTEST Initializing built-in extension BIG-REQUESTS Initializing built-in extension SYNC Initializing built-in extension XKEYBOARD Initializing built-in extension XC-MISC Initializing built-in extension SECURITY Initializing built-in extension XINERAMA Initializing built-in extension XFIXES Initializing built-in extension RENDER Initializing built-in extension RANDR Initializing built-in extension COMPOSITE Initializing built-in extension DAMAGE Initializing built-in extension MIT-SCREEN-SAVER Initializing built-in extension DOUBLE-BUFFER Initializing built-in extension RECORD Initializing built-in extension DPMS Initializing built-in extension X-Resource Initializing built-in extension XVideo Initializing built-in extension XVideo-MotionCompensation Initializing built-in extension SELinux Initializing built-in extension XFree86-VidModeExtension Initializing built-in extension XFree86-DGA Initializing built-in extension XFree86-DRI Initializing built-in extension DRI2 Loading extension GLX ### ## # Mac and Linux users # run this command in another window to setup the SSH tunnel # # ssh -L 5901:localhost:5911 bishopj@corn12.stanford.edu # # Windows users # use these values in SS-VNC # # VNC Host Display: localhost:11 # Proxy/Gateway: bishopj@corn12.stanford.edu ## ### The VNC desktop is: localhost:11 PORT=5911
At this point the VNC server is running. Next step is to setup an SSH tunnel so that the vncclient that we need to run on your desktop/laptop can connect to the vncserver.
If you are running linux or macos on your laptop/desktop I would suggest cutting and pasting the ssh command that is displayed in the output of farmvnc into a new terminal window. For example I would run this command (keep in mind that the username and port numbers will change from what is written here).
Linux/Mac:
ssh -L 5901:localhost:5911 bishopj@corn12.stanford.edu
Windows:
For windows, cut and paste the SS-VNC config from above into the appropriate spots
VNC Host Display: localhost:11 Proxy/Gateway: bishopj@corn12.stanford.edu
choice of vnc client
Ubuntu 13.04 desktop makes use of 3D effects. You can turn some of these effects off, however, you are going to want a reasonably good VNC client. I would suggest turboVNC if it is available to you. For Windows, setting up the ssh tunnel for TurboVNC perhaps makes it not worth the trouble. For Windows, SS-VNC does it tunnel for you so for the moment we recommend using it instead of TurboVNC.
You can get turboVNC from: http://sourceforge.net/projects/virtualgl/files/TurboVNC
You can get SS-VNC from: http://sourceforge.net/projects/ssvnc
MAC: Launch turbovnc and type in localhost:5901
Linux: /opt/TurboVNC/bin/vncviewer -highqual -encodings "tight copyrect" localhost:5901
Windows: launch SS-VNC and enter settings
Type in your vnc password that you set in previous step.
You should see an Ubuntu desktop environment that looks something like this
reconnecting vnc client
If you login to FarmShare again, you can discover your vnc sessions by running listfarmvncsessions as in:
$ module load farmvnc $ listfarmvncsessions active vnc session: TurboVNC ssh -L 5901:localhost:5911 bishopj@corn12.stanford.edu SS-VNC Vnc Host:Display localhost:11 Proxy/Gateway bishopj@corn12.stanford.edu
Logging out
When you are done with your VNC session and you want to shut everything down. Select Logout from the menu in upper right of your screen.
Wait for a few seconds while the logout screen fades in (takes around 5-10 seconds)
Click the logout icon and you should see turboVNC say closed connection.
