VNC (Virtual Network Computing)

I have some problem when execute vncserver in linux, I can't see the
linux desktop which computer I remote. But I only see the IceWM Desktop
(Not same with running program (Desktop) computer which I remote. Could
you help me to get the solv?

Do More with linux and open sources, OK!

Linux is not Windows, and Linux VNC server does not
copy an existing X session, but it creates a session
of its own. This is the behaviour you see, and it
is perfectly correct.

Have a lok at x0vncserver instead of the standard
server if you want a more Windows-like system.

I think you misunderstood how vnc works with linux:

With windows, you get the only desktop available: the one in use.

As linux is a multi user environment, you get a whole new x session
started with vncserver.

It is as if you just logged in a second time.

Therefore you do not get the desktop you see on the screen, but a
fresh, new, empty one.

OK, thanks for your explanation. But I need some configuration about
this file (/etc/vnc.conf). After I installed the execute file (rpm) in
redhat 9.0, this file is nothing. In an articles, I have read that file
configuration is in /etc/vnc.conf.

Buy the way, this is my command in my computer (IP : 192.168.1.45):

# vncsever
Then ;

New 'X' desktop is Pentium4C:1

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/Pentium4C:1.log

In another computer (IP : 192.168.1.44) , I do same command :
# vncserver :1 -geometry 800x600
Then ;

New 'X' desktop is Linux:1

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/Linux:1.log

After that, I do this command:

#vncviewer -fullscreen 192.168.1.45

then ;
vncviewer: ConnectToTcpAddr: connect: Connection refused
Unable to connect to VNC server

But, If I do this commnand :
#vncviewer 192.168.1.45:1
Password: xxxxxx
I can see the desktop on that computer (192.168.1.45). But not same
with running desktop.
Do you wanna help me again?

Best Regards,

Please read my first response again: the standard VNC server
*does not* connect to an existing desktop. Get and read the
VNC documentation again.

use this as your VNC server:
http://www.karlrunge.com/x11vnc/
it lets you connect to an existing x-session on one PC, which then, you
can view with vncviewer on the client side.

Let's not complicate our relationship
by trying to communicate with each other.

OK, VNC has created a *NEW* desktop display on :1 (presumably :0 is
already assigned to your screen?)

I don't see the relevance of this second server

This is trying to view VNC display :0 on the first of your servers (.45),
but there isn't such a thing.

This is successfully connecting to the newly created VNC desktop 1 on
the first of your servers (.45). THIS IS NOT THE SAME AS WHAT YOU SEE
ON THE SCREEN OF THAT SERVER.

It's the same answer as someone else has already told you. VNC on
GNU/Linux platforms does not share an existing display; it creates a
new one.

I suggest you go back and read the advice in the other posts, because
one of them even gives you a correct alternative command to achive
your requirements.
