Do you already know how to intercept tcp/ip network packets?

tcpdump --x -n -ieth0 port 80| nc 192.168.1.X 12345

from a unix box sends the following:

I am running TCP Server from vdsipp.dll

and getting the following:

0 - 192.168.1.32 c0a8 0120 0050 0c46 25f8 fb3c d684 6113
0 - 192.168.1.32 c0a8 0120 0050 0c46 25f8 fb3c d684 6113

Hi Nathan;

Not sure if this is what you want but....

Last year I built a couple of apps that transmitted and received UDP/SNMP packets over TCP/IP. To decode them and troubleshoot the responses I used VDSIPP and a wonderful open source packet analyser. Without the analyser I would have been really stuck. Exclamation
