Hi I used VNC over a VPN (Raptor / Symantec) last year with NT / W2K computers. I never left a VNC connection open for many hours (for security reasons, as I was an administrator). However, I noticed the VPN tunnels regularly (a few times a day) terminated on their own and restarted automatically (keys are supposed to last for a certain while, and then new ones are regenerated). Check with your provider if this is the case and what can be the consequences for the current idle and non idle connections. I also noticed some tcp/ip errors (fragmentation or checksum or header, I don't remember), but they are transparently recovered. So I'm almost sure that there is no need to change the packet size, and this would lead to a performance penalty. I don't believe either that the latencies figures are the problem. I had VNC working over a 300 ms - 3000 ms WAN between Europe and Asia. It was just slow sometimes, and had to click on the refresh menu when nothing happened for a while. Marc
-----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] De la part de Terry Doherty Envoyi : vendredi 20 septembre 2002 23:18 @ : [EMAIL PROTECTED] Objet : Connection Timeout Hello, I'm using VNC both remotely and locally. Locally I have don't have any problem running VNC. It stays connected for days and weeks on end. When I connect remotely through a VPN tunnel I get connection timeouts from VNC and my VNC client window stops responding or dies. Also, my VPN software logs a packet fragmentation error. I'm suspecting that when the VPN software encapsulates the VNC packets it sometimes exceeds the maximum packet size and must fragment the packet. Is there a way to force VNC to use a smaller packet size so that when it gets encapsulated it never exceeds the maximum packet size? It could also be a latency problem. If I continuously ping the host I'm connecting to it occasionally will get a 200-300ms response time. Would that be a problem for VNC? Any help is appreciated.
