 * Cisco VPN client: may hide all packets, even if not connected - disable the firewall in the Cisco VPN client or stop the "Cisco Systems, Inc. VPN Service" -- ''Matthias Andree''

Is this problem special to Win32 systems?!?

Software that's working together with the network protocol stack at a low level can cause problems together with WinPcap.

Some known problems are:

  • SonicWALL Global VPN Client, Version 3.1.0.556: When installed together with WinPcap 3.1, the network interfaces are no longer available (ipconfig /all doesn't show them)

  • Cisco VPN client: duplicates packets, even if not running (installation is enough to cause problems) - Steve Masters

  • Cisco VPN client: may hide all packets, even if not connected - disable the firewall in the Cisco VPN client or stop the "Cisco Systems, Inc. VPN Service" -- Matthias Andree

  • F-Secure Anti-Virus Client Security - disable the firewall part of the suite and it works again. Kim Tiedemann

  • <please append other known problems here>

If you have any such problems, you may contact the WinPcap team directly as the Wireshark developers can't do anything against it.

Discussion

Is this a Win32 only problem, or are other OS/software combinations also problematic?

I had this happen to me using Windows XP Professional, Version 2002, SP2 and SonicWALL Global VPN Clinet, Version 3.1.0.556. This happens with both the 0.10.13 and 0.10.14 downloads of Wireshark. I would be willing to help debug a solution (wvpowell@indesign-llc.com).

We (the Wireshark developers) have outsourced Windows NDIS expertise to the WinPcap developers; you should contact them to see if they can work with you on this. --Guy Harris
