Thanks for the reply.<br>
<br>
However guess, its better to restate my problem, so that i can make you<br>
people clear about my query.<br>
<br>
I am using some 3 NICS ( network interface cards), which together get me 10<br>
ports.<br>
2 NICs are are from D-Link NIC cards which have 4 ports each in them, and<br>
another is NETGEAR NIC, which has 2 ports in it.<br>
<br>
with the help of pcap_findalldevs() , i can obtain the list of all ports ,<br>
along with details of NIC cards, their MAC_ addresses and others.<br>
<br>
But my question is , pcap_findalldevs( ), gives me list of all 10 ports i am<br>
using,<br>
<br>
assume i use a cross-cable and connect any 2 ports to form a loopback<br>
condition,then is their any function in wpcap, which tells me<br>
which 2 ports are in loopback state among the 10 ports i am using.<br>
<br>
or any other function is their apart from wpcap, which helps me to do this.<br>
<br>
<br>
please help me to figure out this problem.<br>
<br>
<br>

Thanks for the reply.<br>
<br>
However guess, its better to restate my problem, so that i can make you<br>
people clear about my query.<br>
<br>
I am using some 3 NICS ( network interface cards), which together get me 10<br>
ports.<br>
2 NICs are are from D-Link NIC cards which have 4 ports each in them, and<br>
another is NETGEAR NIC, which has 2 ports in it.<br>
<br>
with the help of pcap_findalldevs() , i can obtain the list of all ports ,<br>
along with details of NIC cards, their MAC_ addresses and others.<br>
<br>
But my question is , pcap_findalldevs( ), gives me list of all 10 ports i am<br>
using,<br>
<br>
assume i use a cross-cable and connect any 2 ports to form a loopback<br>
condition,then is their any function in wpcap, which tells me<br>
which 2 ports are in loopback state among the 10 ports i am using.<br>
<br>
or any other function is their apart from wpcap, which helps me to do this.<br>
<br>
<br>
please help me to figure out this problem.<br>

I am using some 3 NICS ( network interface cards), which together get me 10 ports.</div><div>2 NICs are are from D-Link NIC cards which have 4 ports each in them, and another is NETGEAR NIC, which has 2 ports in it.</div>
<div><br></div><div>with the help of pcap_findalldevs() , i can obtain the list of all ports , along with details of NIC cards, their MAC_ addresses and others.</div><div><br></div><div>But my question is , pcap_findalldevs( ), gives me list of all 10 ports i am using,</div>
<div><br></div><div>assume i use a cross-cable and connect any 2 ports to form a loopback condition,then is their any function in wpcap, which tells me </div><div>which 2 ports are in loopback state among the 10 ports i am using.</div>
<div><br></div><div>or any other function is their apart from wpcap, which helps me to do this.</div><div><br></div><div><br></div><div>please help me to figure out this problem.</div><div><br></div><div><br></div><div><br>
