DIV class=postbodyBRBRBRBRBR이것은 ICMP 및 ICMPv6를 사용한 ping구현에 대한 예제성격의 소스입니다.BR옛날에도 제가 ping 을 간략하게 구현한바 있었죠.BR이번에 올리는것은 그때버젼보다는 좀더 완성도가 있는 버젼이라고 말할수 있겠습니다.BR게다가 IPv6를 고려한 ICMPv6를 구현한 부분도 추가되었습니다.BR물론 아직도 완전한 버젼은 아니고 다음에 또 기회가 되면 좀더 완성해서 올려볼까 합니다.BRBR테스트 하실때는 당연히 RAW socket을 사용하기 때문에 root 권한으로 실행하셔야 합니다.BRBR DIV class=codetitleBCode:/B/DIV DIV class=codecontent/*BRCopyright (C) INFOEQ co.,LTD.BRAll rights reserved.BRBRAuthor: JaeHyuk Cho lt;minzkn@infoeq.comgt;BRBRTiny ping example sourceBR*/BRBR/* need for struct addrinfo */BR#if 1L amp;amp;
