We use following 1. Compiler - ChunkVNC 3.3.1 2. Repeater - UltraVNC 2011 V2.00 3. Hosting - Goddady Virtual dedicated server. Some times "Listen port server" of repeater closes. If we exit the repeater and re-open it, port will be available. Till what time port will be open is not certain. Some times it gets closed within a minute and some times after one day. Some times it will not close for 2,3 days also. We want know what are the possible reasons for this closure of port in repeater. We have removed antivirus and switched off Windows Firewall also. Still problem occurs. Please help.
We have observed strange behavior yesterday when one customer opens instant support repeater port was getting closed and when that customer closed instant support repeater port was opened itself. it happened two three times. Any reasons for this behavior?. there is no antivirus
Sorry I don't have an explanation for you on this one, you are the first I've heard of such a thing. Are you still using Godaddy VPS for your repeater? If so, could you please try a different provider just so we know that isn't the problem?
If instant support is opened in a System with "Escan" antivirus, then the repeater port closes. In the same system PC_helpware works. Both instant support & PC_helpware connect to same website & same repeater.(port number is also same). But only when instant support is opened, repeater's port gets closed. why?
I think we need to draw our attention to some possible bug in Instant support!
ChunkVNC is written in the AutoIt language which a lot of (poor) virus scanners don't like. Not much we can do here except tell the antivirus to mark it as safe.
Just for notes if it helps: InstantSupport makes an outgoing connection the repeater server port to make sure it's up. Then it launches the UltraVNC server making the reverse connection. You could try doing a manual reverse connection with the UltraVNC server to see if Eset still blocks it. It might be a matter of removing the initial check that InstantSupport does.
