I strongly discourage VNC, it's not very secure unless you plan on
tunneling it through ssh. If you can, your better off using remote desktop,
but if that for some reason doesn't work for you, then I would suggest you
look into Simple Desktop:

http://www.moogsoftware.com/pc%20remote%20control.html

Their site looks nasty, but their Simple Desktop program is rather secure
since you can choose from several different types of encryption protocols
with up to 576 bits. The program is freeware, and you can run it in a
browser like you can VNC. I have it running on a few computers that I
needed an actual terminal screen on, and so far I haven't had any problems
with it.

First off, sorry Simon.  I ment to send this to the list but sent it to
only you instead.

Now, on to my real question.

I'm looking to use VNC on my windows machine for remote logins.  Currently
I only have the following open ports:

25/tcp   open   smtp
80/tcp   open   http
113/tcp  closed auth
1352/tcp open   lotusnotes
5902/tcp open   vnc-2
5903/tcp open   vnc-3
8080/tcp open   http-proxy

Are there any security problems that I may be over looking by using VNC on
my machine?

Regards,

JL
