When sniffing network traffic with Wireshark, I can see only the TCP
3-way handshake captured but not the traffic itself afterwards. This
happens using any winsock application including Internet explorer and
such , see attached: Browsing_through_iexplore.cap
The most bizarre thing is that if I am doing "telnet" to the same web
server and passing data through the connection I can indeed see the
traffic, see: Browsing_through_telnet.cap
I thought at first it could be a running Antivirus application or such
that at some level captures the network traffic to analyze viruses
before it reaches winpcap but I doubt it because no such application
exist on the server.
I wouldn't worry about AntiVirus software but rather VPN software. Any
of that installed?
