My PC is running windows XP. I have been trying to capture HTTP traffic but if I apply the following filters, the Wireshark gives results not required
httpresult: it only show ssdp traffic
http (!udp)result: it does not show any thing
http (!http contains ssdp)result: it does not show anything
http && tcp result: it does not show anything
http (!udp.dstport == 1900)result: it does not show anything
tcpresult: it shows tcp traffic but I cannot reach my required http messages
The same thing is happening when I run it on a different OS (Windows 7) on my laptop.
