tcpdump 툴로 패킷을 잡아서 분석하는 레포트를 하다가..

만만하다~ 싶어서 한번 만들어봤습니다.. ^_____________^


TCP/IP 패킷(TCP/UDP/ICMP)

이동경로(IP/MAC), 패킷길이, TTL, 프로토콜, 윈도우사이즈

3 Handshaking, Sync, SeqNumber(시퀀스) 보여주기

개발환경 : Linux 2.4.18, gcc


컴파일 명령 : gcc pico.c -lpcap -o pico_dump

실행 명령 : pico_dump  src_ip_addr  dst_ip_addr

(src_ip_addr, dst_ip_addr 생략 가능 - 생략시 초기값으로 실행)

src_ip_addr(출발)과 dst_ip_addr(종착)호스트 사이의 통신을 감시
