VNC Server in Neutrino

Hi, Guys,

I have tried a lot of time on getting VNC server work with no luck. The following are information from the ~/.vnc/log file:

19/10/05 14:17:36 Xvnc version 3.3.7 - built May 21 2003 15:23:36

Anybody know what is wrong and what to do?

Thanks a lot,

I guess your hostname is lwslaptop. Make you have it in your /etc/hosts file. You can add it next to the “localhost” if you don’t have a permanent IP.

Thanks a lot. Vncserver can start now.

But still a problem: I cannot connect to it from my XP machine. The VNC Viewer error message is : Unable to connect host; Connection refused (10061).

Both of my XP and QNX machine are dhcp.

Any idea of what’re wrong?

Thanks a lot for assistances,
Jeff

A few things could be wrong:

  1. There is a firewall on your XP that blocks this outbound traffic.
  2. There is a firewall in between your XP and QNX, that blocks the VNC traffic.
  3. The IP address you used to connect is wrong.
  4. The port number you used to connect is wrong.

Thank you very much for your inputs. Appreicate it a lot.
