    Question VNC server issue

    I am trying to connect to Backtrack 4 R1 from a windows computer using TightVNC Viewer. I started the VNC Server Service and entered passwords. I can successfully connect and see the screen, but the problem is that I need to see the same working screen as is showing on the running backtrack computer. The screen I end up with is a fresh new window that does not show the same working screen, like a back door into backtrack. I need to show what I am doing over VNC for a presentation.

    That is not a problem that is normal behavior. One would call it a linux feature.
    Might I suggest teamviewer?
    To be successful here you should read all of the following.

    Failure to do so will probably get your threads deleted or worse.

    I'm guessing you only need a few applications to be in your VNC session for your presentation. The easy way around without using teamview is to VNC into your backtrack computer locally, start the applications you needed "shared", then when you VNC from the remote windows workstation, the things you needed will be there.

    To VNC into your backtrack machine locally I like to use
    Code:
    root@bt:~#vncviewer 127.0.0.1:5901
    Then start whatever you need.

    I also always create a tunnel to my localhost and VNC in through the tunnel, when using a VNC screen from a remote VNC server. VNC passwords are transmitted across the wire in clear test like telnet and FTP. The tunnel protects your credentials and session.
    Code:
    c:\ssh -L 5901:127.0.0.1:5901 user@hostname.or.ip.address
    When connecting in windows using VNC you connect to
    127.0.0.1:5901

    If you are using KDE, install krfb

    I'd actually recommend you apt-get install x11vnc. It does exactly what you want (it does the same thing krfb does), but it's overall faster and more efficient than krfb.

    x11vnc "syncs" what you're doing with what's actually going on. You will notice it's a bit slower than TightVNC, but it's the only option.

    Thanks for all the replies!

    Because I am directly connected to the network, I was trying to avoid using TeamViewer (I have seen the TeamViewer servers down before and that is not acceptable).

    I like the idea of being able to remote in to the local computer, I didn't even think of that. I will keep that as an option.

    But I have opted for installing x11vnc. I found the command options to allow me to VNC into the current session, the -display :0 does that.

    x11vnc -viewonly -display :0 -auth .Xauthority -passwd (my password)

    It works easiest for me so that is what I am using. Thank you all very much.
