Cannot capture packets from remote system.

0

I have installed winpcap on a Win 7 Pro system, including opening tcp port 2002, and starting the service. However, I cannot capture any packets from this system. I get this error: "Error while capturing packets: is the server properly installed on x.x.x.153? connect() failed: A connection attempt failed because the connection party did not properly respond after a period of time, or established connection failed because connected host has failed to respond." I have 3 remote adapters showing up for this system and I have tried all 3 with the same results. Any help is appreciated. thanks

Which service did you start?

I have narrowed my problem down. I turned off the Windows firewall on my Win 7 system and now I can capture packets from this system. However, I have opened the tcp port 2002 that is specified in the Wireshark users manual. What other port(s) do I need to open in order for this to work without having to turn the firewall off?

It looks like port 2002 is it: http://www.winpcap.org/docs/docs_412/html/group__remote.html

Make sure another process is not listening on this port. The Logmein remote access application was using tcp port 2002 on my computer. You can also specify a different port for remote capturing.
