쿠분투에서 인터넷 설정(dhcp)..Network down..

페도라에서 쿠분투로 전환해 보았습니다 ^^

뭐 설치야 페도라만큼 쉽더군요.. 그리고 랜카드도 잘인식하고..(리얼텍..)

근데 dhcp 자동설정?이 실패하길래.. 일단 나중에 X 들어가서 설정해야겠다,, 하고

일단 그부분을 넘어갔죠..

X-win 들어간후에 전처럼(fedora3 처럼) (경로는 좀 다르지만,,)
dhclient.conf 파일에 다음과 같이 설정해 놨죠..

interface "eth0" {
send host-name "skynet.skynet";
send dhcp-client-identifier MAXADDRESS...;
script "/etc/dhcp3/dhclient-script"
}

그래서 확인차 dhclient 를 실행해 보았습니다 그런데..

root@skynet:/etc/dhcp3# sudo dhclient
There is already a pid file /var/run/dhclient.pid with pid 0
