Instructions for Connecting to Workshop

There will be multiple connection paths to the workshop for remote participants. For audio, we will have both telephone and ESnet video conferencing set up. For presentations, we will be using VNC. Instructions for connecting to each are given below.

Instructions for connecting via telephone

To connect by telephone:
1.) dial:
 800-377-8846 : US
 888-276-7715 : Canada
 302-709-8424 : International

2.) enter participant code: 39527048#  (remember the "#")

Instructions for connecting via ESnet

ESnet is a video conferencing system used by US DOE labs. Information on the system can be found at:

http://www.es.net

If your are using a Polycom ViewStation, make sure the connection type is set to "IP".

To connect to the conference, dial:

8542553


Instructions for connecting via VNC

VNC is a desktop sharing program that allows users to see and, if allowed, control a remote computer's desktop. There are several client programs out there that are freely available for most operating systems. Links to pages where client programs can be found Linux, Mac OS X, and Windows are given in the respective sections below.

IMPORTANT:
Cyber security realities require that all remote connections (i.e. outside of JLab) be done in a secure way. The preferred and perhaps only method is through an ssh tunnel. A tunnel can be created by the ssh client to listen on a certain port on the local machine and forward the connection through the encrypted ssh tunnel to a remote machine. Tunnels can be created easily using command line arguments on Linux and OS X and though a GUI on Windows. Instructions for doing this on each of these three systems are given below.

Linux
Many Linux systems already have the vncviewer program installed. If it is not, first check your installtion disks and if you're still unable to find it, you can try on the web a someplace like here:
http://www.tightvnc.com/download.html

  1. Open an SSH tunnel: Open an new terminal and enter the following, replacing "myUserName" with your JLab CUE account name.

    ssh -L5908:129.57.120.44:5908 myUseName@jlab.org

    You should be prompted for your password. Once you enter it and are sucessfully logged in, you can minimize the terminal window, but do not close it. As long as that window is open, the tunnel will remain in place.

  2. Connect with your VNC client and have it connect to display "8" on your local machine. You can use "localhost" to specify the local machine. For vncviewer, the command would look like:

    vncviewer localhost:8

  3. Enter the password when prompted. The VNC session password is "excited" (no quotes).

Mac OS X
Chicken of the VNC seems to wok well. This is what I use and it can be found here:
http://sourceforge.net/projects/cotvnc/

  1. Open an SSH tunnel: Open an new terminal window. On Mac OS X, use the Terminal program in Applications:Utilities. Enter the following, replacing "myUserName" with your JLab CUE account name.

    ssh -L5908:129.57.120.44:5908 myUserName@jlab.org

    You should be prompted for your password. Once you enter it and are sucessfully logged in, you can minimize the terminal window, but do not close it. As long as that window is open, the tunnel will remain in place.

  2. Open your VNC client and have it connect to display "8" on your local machine. You can use "localhost" to specify the local machine. For Chicken of the VNC, your connection settings screen should look something like this:

    For the password enter "excited" (no quotes).


Windows
There are a few clients for Windows.UltraVNC provides both a server and a client. It is what will be used as the server for the workshop. You can find UltraVNC here: http://ultravnc.sourceforge.net/

  1. Setup port forwarding: Open the PuTTY program and select tunnels from the menu tree on the left. Look towards the bottom of the port forwarding section and enter the information for "Source Port" and "Destination" as shown. Make sure the "Local" button is selected then click "Add". It should copy the information into the "Forwarded Ports" box also shown. (Note, once you click "Add", the "Source Port" and "Destination" boxes will be cleared so it won't look exactly like shown below where the information is in both places at once.)

  2. Open an SSH tunnel: Click on "Session" at the top of the menu tree in the PuTTY window. Enter "jlab.org" for the host name and make sure the "SSH" button is connected. The window should look something like this:

    Click "Open" to initiate the connection to the JLab login server.

    You will be prompted for your username and password. These are your username and password on the JLab CUE system. Once you enter them and are sucessfully logged in, you can minimize the PuTTY window, but do not close it. As long as that window is open, the tunnel will remain in place.

  3. Open your VNC client and have it connect to display "8" on your local machine. You can use "localhost" to specify the local machine. For UltraVNC, your properties screen should look something like this:

    For the password enter "excited" (no quotes).
