I saw this several times on the list but I could not find the solution to the problem. I have a Linux and a NT box. Running VNC as a server on the Linux and VNC as viewer in listen mode on the NT. There are no problems connection each other as server or viewer. But now, I do not understand the following. Connecting to the Linux box with SSH and making a reverse connection with vncconnect -display linux:1.0 winnt Works fine! Running an X-server on the NT and displaying a xterm window on the NT box and then giving the same command, gives the following error: Xlib: connection to "linux:1.0" refused by server Xlib: Client is not authorized to connect ot Server vncconnect: unable to open display "linux:1.0" Why can't vncconnect, running in the shell displayed in a xterm window on my Windows NT's X-server, connect to that VNC server still running fine on the Linux box? Is this a question of operating system security? Isn't that possible and why? Where is the difference in running vncconnect in a SSH connection shell and the xterm shell? I think there must be a simple explanation but I could not figure out...
