Larry, Thx for the clarification. But, I came across the below link that conveys that the network support in Cygwin is supposed to provide the POSIX API, not the Winsock API - http://www.cygwin.com/faq/faq.api.html#faq.api.net-functions What does the above link refer to ? Interestingly ,the below link conveys that raw sockets is supported unofficially ! Strange ! http://sourceware.org/ml/cygwin/2005-10/msg00753.html But, how & why is it supported unofficially ? The below link seems to convey the problems of using the Raw sockets with Winsock and it also about the restrictions w.r.t various windows releases - http://tangentsoft.net/wskfaq/advanced.html#rawsocket So, is the method of usage of winpcap is the only way to use raw sockets in cygwin environment ? From http://www.winpcap.org/docs/docs_41b5/html/main.html , I find that the purpose of WinPcap is to give this kind of access to Win32 applications that it provides facilities to: 1. transmit raw packets 2. capture raw packets and 3. filter the packets Any other ideas/ways apart from winpcap to use raw sockets in cygwin environment ?
