Instructions for Windows
Downloading the Software
You'll need two pieces of software:
- VNC client (lets you view the remote screen): UltraVNC
- UltraVNC comes in a zip file. Open it and drag the executable inside to your desktop next to putty.
- putty (lets the client talk to the remote machine through the firewall): PuTTY.
- You want to save the putty.exe to your Desktop.
Setting up PuTTY
Configure host name of remote machine
- Fill in the Host Name and Saved Sessions field as shown.
Configure user name
- Select the Data entry under Connection in the left column.
- Fill in the Auto-login username field.
- Click on the + next to SSH in the list on the left, then select Tunnels.
- Fill in the Source port and Destination fields as shown.
- Then click on the Add button.
- Select the Session entry in the left column (scroll up if you have to), and click on the Save button. This will save your settings.
Open the session
- Select hacuser@hacweb2 from the Saved Sessions list and click Load.
- Click on the Open button at the bottom of the dialog box. A black terminal will open and prompt you for the usual hacuser password. Type it in and you should get a normal shell prompt.
- You can now minimize this window (do NOT quit PuTTY) and setup UltraVNC.
Using these sessions in the future
You only have to create the above configurations once. Next time, you just have to do this:
- Run putty, select 'hacuser@jlab Step 1', and click 'Load', then 'Open' login, then minimize that putty window (leave it running)
- Run putty, select 'hacuser@jlab Step 2', and click 'Load', then 'Open' login, then minimize that putty window (leave it running)
- Run UltraVNC and hit Connect (it'll use the default settings you saved earlier)
Setting up UltraVNC
- Enter localhost:5901 in the "VNC Server:" field at the top.
- Enable the Save connection settings as default at the bottom.
Connect to the VNC session
- Click on the Connect button and you should see a couple of windows pop up:
- Enter the hacuser password in the appropriate box and hit return.
- You should be rewarded with the hacuser X session.
- NOTE: If you get a black screen with yet another password prompt, it means the screen saver software has kicked in. Just type in the 'hacuser' password again and you'll be good to go.
Quitting the VNC session
- Be sure to close the UltraVNC window, not one of the windows running
inside the VNC session.
- Any program/stripchart that you start inside the VNC session will keep
running and updating in the background. You can reconnect to the VNC session anytime from (nearly) any machine.
Instructions for Linux
- Type the following at a shell prompt (ie. in an xterm)
vncviewer -Shared -via hacuser@hacweb2 :1
- When prompted, enter the hacuser password (twice)
Setting up the VNC Server
- Log in to hacuser@hacweb2
- Start the vncserver by running:
[hacuser@hacweb2]# vncserver -geometry 1600x1100 :1
Killing the VNC Server
This will quit the server and all applications that were running under that server.
[hacuser@hacweb2]# vncserver -kill :1
