Okay, what you got now is the KDE Remote Desktop implementation of vnc...
The XWindows VNC (Which I've never done!) Would be.....
=============

Yep, you guessed it. Adding the vnc module to the XConfig file, (and
removing) turning the KDE Remote Desktop off.

I Use the Vnc Terminal Server approach, as I don't really want to see
what's on the screen down stairs, I just want a graphical environment
(or two 8-). It's also easier to setup (I think). Some one else will have
to jump in and help you out with that, as I wouldn't know how to set
the required password.

The Terminal Server process is setup as follows:
got to: Yast2->Network Services->Remote Administration
  There you select "Allow Remote Administration"
  I would not select "Open firewall port", but the risk is yours.
  Click finish

Now on XP connect with vncviewer to Linux as usual but add ":1" to the
end of the linux-ip address. You should get a graphical login just like
you do on the linux screen!

If you like this, but want bigger desktops, you can go to:
Yast2->Network services->Network services (xinetd)
There scroll down till you find vnc2, (and possibly vnc3?).
Select the line, click "Toggle On/Off Status",
Click Finish...

Now you can get 1280x1024 screens by using the suffix :2
and 1600x1280 with the suffix :3

Secure Remote access from Internet
=======================

my way to do this is via ssh. Now many other people have other ways.
Here is how to vnc via ssh from linux:
vncviewer -via <remote-user>@<remtoe-ip> localhost:0 (or :1, :2, etc).
After entering the remote user's password vnc-window will open up...

Of course, under windows it's a good deal more complicated!
First we get it working from XP to Linux INSIDE your network,
then we mess with your routers!

So you need a windows ssh client. Putty is the defacto Freeware standard
and it's on the SuSE DVD's. install it.

Then you need to open an encrypted tunnel from you XP to Linux that is
pointed to the VNC server of your linux. This is down as follows:

Start up Putty:
- Enter linux host name or linux ip address.
- Select ssh.
- (in lefthand category tree) select SSH
- click Enable Compression (this compresses the data thru the tunnel)
- (in lefthand category tree) select Tunnels
Now Depending on Which VNC you want to connect to
do one or more of the following:

Tunnel XWindows VNC or KDE Remote Desktop:
- Create a local tunnel from XP port 5950 to linux and
  from there to localhost:5900
  - put 5950 in source port
  - put localhost:5900 as Destination.
  - Click add

Tunnel Vnc Terminal Server login 1024x768 size
- Create a local tunnel from XP port 5951 to linux and
  from there to localhost:5901
  - put 5951 in source port
  - put localhost:5901 as Destination.
  - Click add

Tunnel Vnc Terminal Server login 1280x1024 size
- Create a local tunnel from XP port 5952 to linux and
  from there to localhost:5902
  - put 5952 in source port
  - put localhost:5902 as Destination.
  - Click add

Tunnel Vnc Terminal Server login 1600x1280 size
- Create a local tunnel from XP port 5953 to linux and
  from there to localhost:5903
  - put 5953 in source port
  - put localhost:5903 as Destination.
  - Click add

After you defined your tunnel(s), You need to save the settings!
- (in lefthand category tree) select Session
- In Saved Sessions enter a name
- Click save

Okay... Configuration is done:

Now you can start the tunnels by double-Clicking the name
in the list under saved sections.
You will get a "Dos-Box" (actual your linux shell) where linux
will ask you for username and password.
After entering then you get the linux prompt, as long as this
linux terminal is open the defined tunnels are open.

So now you can connect to linux via vnc by connecting to
The ports 5950, 5951, 5952, and/or 5953.

NOTE: Theese are the entrance ports to the tunnels from
your XP to linux; so the ports are on your local XP!

So start vnc, enter as address localhost:50, (or :51, etc)
and you wil get a Secure (and compresssed) vnc connection
to your linux machine.

Boy that was a long one....
And I probably confused everbody out there!

Oh well, I'll let you get past this before we discuss how to
modify your internet router to allows ssh in to your linux box
(and thereby allowing you to securely access both your Linux
and your XP boxes from the internet!)
