<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;"><span style="font-family: monospace;">HI<br><br>I'm trying to use libpcap to build a software bridge using lan card and wifi card I open both cards using pcap_open_live(). Then I start two threads, each collecting frames on one of the card using pcap_next_ex() and then thread sending the frame using pcap_sendpacket(). Every thing seems fine but when i try to ping from my wifi card the ethernet card of some other machine. the wifi card gets RARP (<IP> is at <MAC Adress>) but it does not generate the echo request.</span><br><blockquote dir="ltr" style="margin-right: 0px;"><div><font style="background-color: rgb(222, 235, 246);" color="#00007f" face="verdana"><strong>Muhammad Tassadaque Zia</strong></font></div></blockquote></td></tr></table><br>
