設定
- /etc/sysconfig/network-scripts/
- ifcfg-eth?:? を作る
- 書式は通常の ifcfg-eth? と同じ
- 例
- dhcp (後述)
DEVICE=eth0:0 BOOTPROTO=dhcp ONBOOT=yes DHCP_HOSTNAME=centos5-test
- static
DEVICE=eth0:0 BOOTPROTO=static IPADDR=192.168.40.250 NETMASK=255.255.255.0 GATEWAY=192.168.40.2 ONBOOT=yes DHCP_HOSTNAME=centos5-test
- dhcp (後述)
- ifconfig

dhcpについて
- 以下の問題は、BOOTPROTO=static の際には発生しない模様
- ifup eth0:0 でエラーが出る
Determining IP information for eth0:0...SIOCSIFFLAGS: Cannot assign requested address SIOCSIFFLAGS: Cannot assign requested address done.
- IP自体は正常にassignされる
- ifconfig

- ifconfig
- boot時のエラー
- IPもassignされず
- fconfig eth0:0
