VNC Problem

Hello,

I want to use VNC to controll a server (Linux) remotly from my PC (WinXP). I
started vncserver on my Linuxbox entered a password and tryed to log on from
the client entering IP:1 in the vncviewer. In the log file of the server I
can see that a client did connect, but on my client I don't get any screen
(I even don't get the password dialog). Any idea what is wrong?

Cheers,
Jochen

Sounds like there may be a firewall enabled on your GNU/Linux box that
is blocking the port. At this stage, try turning off the firewall and
see if that helps ("/etc/init.d/iptables stop", or some such equivalent).

Hi Chris,

I haven't the command iptables in the directory you specified. Anyway I can
use the command, but it doesn't know the parameter "stop". Any other idea?

Regards,
Jochen

Forgotten to mention: the http access works. Anyway, I would prefer to use
the native VNC.
BTW, can I use VNC to get any kind of desktop? I would like to use KDE
desktop via VNC.

Thanks,
Jochen

This shows that your VNC client has successfully connected to your VNC
server on display ":1". Have you set a VNC server password?

Chris

Hi,

yes I've set a server password, but I don't see anything on the client, not
a single window or message. When I have connected and shut down the server,
I get message on the client. Something like "connection broken". But before
that just nothing happens.

For the client I use version 4.0 on windows.

Regards,
Jochen

Update of the server has helped.

Thanks for your support.

Jochen
