2) touch/var/lib/dhcpd/dhcpd.leases 를 만들어주었습니다.
3) /usr/sbin/dhcp eth1 을 실행했는데 메세지는 다음과 같습니다.
[root@localhost etc]# /usr/sbin/dhcpd eth1

참고로 RHEL AS 4.0을 쓰고 있습니다.
---------> 문제는 eth0은 랜카드 설정을 DHCP서버로 잡았습니다. 모뎀으로부터 나오는 이동아이피를 정확히 알수가 없습니다. 우선 들어오는 아이피를 알기 위해 PC에서 읽은 아이피가 192.168.1.97이네요. 그래서 전 eth1도 역시 위의 dhcpd.conf룰 설정한 상태에서 DHCP서버를 선택해서 잡았습니다. 여기서 eth1을 고정아이피로 주지 않으면 활성화가 되질 않습니다. 그리고 잘 되던 eth0의 인터넷도 되질 않습니다. 문제가 무엇인지요. 아 답답하네요.......헉
---------> DHCP서버로 잡으로 매스커래이드와 같은 것을 사용할 필요가 없는것 같은데 맞나요.
감사합니다.
