We have a linux client which boots a small ramdisk image into RUN Level 3,

Runlevel 3 is not that well defined... If this is a graphical (X11)
based display, then there are several ways to make it viewable with a
vnc viewer. If it is a text (character) console, then there are better
ways to make it remote available.
For X11, there are the next ways:
The most easy way (well, for unix admins) is to replace the available
X11 server with Xvnc. That is an X11 server (X11R4 by head, no optional
parts available). See that it gets its dedicated vnc options and off you
go. Advantage: the console is available over the network. Disadvantage:
the graphical console is not available on the physical console, that
drops back to character mode...
With most distributions, there is a vnc (vnc-server) package. Install
that and use it to start the commands in stead of the console. Then the
app runs at this virtual display but not at the console.
There are vnc-modules for most current X11 servers as they are available
on linux. This provides a way to hook into the display at a relative low
level: it can also be used to login to the system.
There are vnc-options inside both Gnome and KDE. See your distribution
for details. This provides a way to hook into the session at a relative
high level: it is only available if a user is logged-in, it is
controllable by the console user and it resets at logout.
If the console is in text mode, vnc is not the way. /dev/console is the
device to hook into to get grip on the console, however, it does not
provide a way to see what is already there and above all, there are
various applications that can handle this but are hard to configure.

The linux client can only talk to the server it boots from, via ethernet.
That subnet is not accessible from outside of the lab.
I can access the Linux server via ssh, filezilla, etc, from outside the lab
using Windows machines.
We usually walk up to the client, log in, and run some test programs which
take hours.
I'd like to be able to remotely monitor the program running on the Linux
client, from the Windows machines, outside of the lab.
Is it possible to use VNC to forward the "console screen" to the Linux
server, then connect to the Linux server from the Windows machines, in order
to
monitor the test progress on the Linux client?
