Need VNC help

I am trying to connect to Windows 7 laptop that has an app I need to monitor, it's all on my local home network.

I have VncReal 4.0 running on the Win7 laptop. It says it can accept remote connections. I have it setup so as to receive connections from only one ip address. I also have it set for no encryption and no Authentication.
There is no valuable data on this laptop. It looks like it is set to use port 5900. I have never used VNC before.

I have tried to connect using xvnc4viewer, xvncviewer, vncviewer gvncviewer and rdesktop. Assume Windows ip address is
I have tried each with:

<viewing app>
<viewing app>

Nothing seems to connect. Any sugestions?

I've never used VncReal before but it sounds like vnc service is not running on remote machine. enable this on startup within the application

I've used alot. Very easy to setup and connect to. Setup on server side with password and on my host machine that has vncviewer installed, I do:

# vncviewer

How do you know?

I would test connectivity from the Linux system first.
telnet 5900
tells you if somebody is listening on the other side. If the telnet program manages to connect, somebody is listening indeed. Type a few random keys and hit enter, and you should receive an error code from the other side.

If you can't connect, it might be because the port is closed or because nothing is listening on that port. Off the cuff, I can't say what kind of error you would get in either case, but Google etc. might help there.

It was the firewall on the laptop. I had checked the firewall on the router, but forgot the windows firewall.
