: What can I do so we all see the same?? 

If what you want is multiple people to be able to join together,
that's possible in the unix version of VNC; what isn't possible is
to see the existing X sessions provided by the unix-vencor-supplied
X installation.

: we are working both in a third machine a HP-UX 10.20, we make telnet
: connections and work there, so maybe I must install vnc server in this
: workstation, no? 

You can install the VNC server anywhere you can both reach via TCP
(roughly, anyplace you could telnet to (that's only an approximation
given the way firewalls are configured nowdays; but you can use it
as an approximation).  For example, let's say we have users A and B
who both have a unix box, and a third unix box C upon which A&B wish
to run processes that they can both work on together, and both see
simultaneously on their own screens.  And let's say all three of these
boxes are mutually reachable via tcp; no firewalls between.

Then, you can start Xvnc running on ANY of the three boxes, and start
two copies of vncviewer, one on A's box and one on B's box, both viewers
set to connect to the same server.  Then, if the Xvnc was running on
C to start with, you're done.  If Xvnc was running on A or B (or D
or anything other than C) you'd have to telnet over to C; but BOTH
A and B would "see" that same telnet session on their desktops.

Is that clear?  For an example, if you install vnc on all three
machines (A, B and C), then for example on C you could run

          vncserver -alwaysshared

and it should get screen :1 on C.  The server can be started remotely.
Then, on both A and B, you'd run the viewer with the same command

          vncviewer C:1

and then the users sitting at A and B should then be able to thumb-wrestle 
for control of the mouse cursor on C's virtual X screen....

Now, if you don't want to install vnc on C (let's say, you don't
want to bother with the HP executables, or for whatever reason).
Then on A you could run the server on node A:

          vncserver -alwaysshared

and both A and B, you'd run the viewer witht he same command

          vncviewer A:1

and the first thing you'd do in that virtual desktop on A is

          telnet C

All clear?
