<BR>Thanks for your replies guys , but the problem is still remain. Suppose if i create an application which work in background to capture only URLS.Then i dont want my client to select the adapter by himself , 70% of commercial users are not technichal so instead of telling them to select their approperiate adapter for capturing packets seems not OK with my specifications. Plus i cant run two modules of winpcap on a system if i will do that then suppose a person has 3 adapter one genric dilaup, other twos are LAN ethernet and WAN then it became like 3 threads which will work on all of these adapters to capture the TCP IP data, while one of them will be working. So thats why i want that application to detect itself that which adapter is currently perfect to catch the data. Hope you guys got the idea of it now??<BR>
<BR>
Also my OS is winxp<BR>

If what you are interested in is IP traffic, I would probably list the adapters with their associated IP addresses. In the simple case (a machine with just one wired or wireless connection), you will get two (or three) adapters and only one of them will have a (valid) IP address associated to the adapter. And you will pick that one.<BR>> Things get much more complicated if<BR>> 1. the machine has more than one adapter<BR>> 2. (a special case of 1.) the machine has a wired and a wireless adapter (all the modern laptops have both), and the user switches often between the adapters (or use both of them at the same time). In this case you will need to capture from both the adapters.<BR>> <BR>> Hope it helps<BR>> GV<BR>> ----- Original Message ----- <BR>> From: *farhan Khan* <BR>> To: winpcap-users@winpcap.org <BR>> Sent: Tuesday, November 13, 2007 11:29 AM<BR>> Subject: [Winpcap-users] how to auto detect the interface<BR>> <BR>> <BR>> hi,<BR>> i am new user of this mail list, i would like to know how can i detect which interface is the correct one to capture the packets on TCP 8080/80 and 1080 etc. I want my application to select approperiate interface automatically without user's input for the interface....
