I'm running the latest Free RealVNC server in service mode on a WinXP

unexpectedly. I'm not prompted for a password.
I realized that I was allowing connections only from a certain other
machine on the subnet, and was therefore blocking connections from
localhost. I fixed that and then was able to make the connection from
localhost. So I guess this is what we see in the event log when WinVNC is
disallowing a connection (at least if it is from localhost):
SocketManager: unknown listener event: 0
This is still a problem:
But when I try to connect from a Linux machine on the subnet, it doesn't
register anything. When I use nmap on the Linux box to look at the
Windows box, I see that port 5900 is "filtered" rather than "open".
I was able to use "vncviewer -listen" on the Linux box to receive a
connection from the VNC server on Windows. That worked but only
momentarily. It locked up almost right away and then the VNC server
crashed on Windows, including the usual Microsoft request to report the
error, which I did.
Any ideas? Why would the server crash after making a connection to a
listening viewer?
I'm guessing that my problem making a normal connection is due to some
kind of firewalling problem. I'm trying to turn all of that off. It's
hard to figure out exactly where the problem is, though.
