1) Makefile.in에서, AM_CXXFLAGS와 AM_FLAGS의 -Wall을 -lrt로 변경한다. 솔라리스는 nanosleep(3RT)이 librt(3LIB)에 있다. -Wall은 GCC용 옵션이기 때문에 CC에서 컴파일시 삭제해야 한다.

iperf -c 서버IP [-u] [-i] [-p 포트번호] [-w n[KM]] [-b n[KM]] [-t n] [-n n[KM]]
-u UDP를 사용. -b 옵션을 반드시 사용해야 한다. -i 출력 간격(초). -p 바인드할 포트 번호. 기본값은 [-p 5001]서버/클라이언트 옵션
-D 데몬으로 실행. -d 양방향 테스트 -b 대역폭. 기본값은 [-b 1M] -n 보낼 전송 회수. -t 대신 사용 -t 보낼 시간(초). 기본값은 [-t 10] -w 윈도 크기(버퍼크기).자세한 사항은
iperf -h 나 iperf(1)을 참조하자.
