Windows client dies at random
Mon Nov 18 14:10:01 2002
I have just started getting this problem (hanging and crashing) on 2
different client boxes (one into a Windows 2000 server, one into a Linux
server - from the box running the WIn2k server, as it happens).
For me it has only started to happen since I moved to 3.3.4 but it still
happens with 3.3.5. I was thinking of switching back to 3.3.3r9 with which I
never seemed to have a problem. I am disappointed that you get it with
3.3.3! I have used 3.3.3 in Windows, Linux and Solaris environments with
never (as far as I can recall) a problem.
I do use ZoneAlarm (the free version) but that hasn't changed for ages - it
is only the upgrade to 3.3.4 that seems to have provoked the problem.

Subject: Windows client dies at random
I'm suffering intermittant failures of my VNC viewer, which may be
associated with ZoneAlarm Pro.
I am connecting from a Windows XP Home Edition (SP 1) machine to a
Sparc Solaris 8 box. Connection works fine and I can work in my
OpenWindows desktop environment - for an indeterminant period varying
from under a minute to when I'm done and shut down the client manually,
sometimes well over an hour. When the client dies it just disappears,
without warning. Almost always it leaves a notification box with the
helpful diagnostic "Connection closed"; perhaps 10% of the time there's
no notification box at all, and once or twice I have seen a somewhat
more technical message (which escapes me at the moment). In the VNC
server log on the Unix box it just says "Client <IP address> gone,"
followed by session statistics.
Other details: server is Xvnc version 3.3.3. Client is TightVNC
viewer version 1.2.6 - but I've tested the "real" VNC version
(approximately) contemporaneous with the server and have the same
failures. I am 99% certain that I did not see this problem during the
two weeks or so I was running this system before installing ZoneAlarm
Pro; I have fiddled with Zonealarm's settings without affecting this
behavior (specific suggestions welcome). The other details of the
setup are: Linksys router with firewall, cable modem (Roadrunner),
Contivity VPN client (the Solaris box is behind a corporate firewall).
A Windows 98 system connected to the same cable modem and running the
same software (but no ZoneAlarm) has no such problems.
Diagnostic questions or suggestions, before I deinstall ZoneAlarm?

It is not easy, these days, to go beyond the bounds of taste.
