NIC alias
- 一つの物理NICに複数のIPを割り当てる
CentOS
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 (static)

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

- ifconfig eth0:0
- assignされた
- assignされたりされなかったりするため、不安定
Ubuntu
設定
- 全て /etc/network/interfaces に記述
# The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet dhcp
- 例
- dhcp (後述)
auto eth0:0 iface eth0:0 inet dhcp
- static
auto eth0:0 iface eth0:0 inet static address 192.168.40.250 netmask 255.255.255.0 gateway 192.168.40.2
- dhcp (後述)
- ifconfig (static)

static時の問題
- /etc/network/interfaces
auto eth0:0 iface eth0:0 inet static address 192.168.40.250 netmask 255.255.255.0 gateway 192.168.40.2 - sudo ifup eth0:0
SIOCSIFFLAGS: Cannot assign requested address
- 実際には正常にassign
- ifconfig eth0:0
eth0:0 Link encap:Ethernet HWaddr 00:0c:29:YY:YY:YY inet addr:192.168.40.250 Bcast:192.168.40.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:17 Base address:0x2000
- ifconfig eth0:0
- wireless-tools のバグ？
- 対応
- sudo chmod -x /etc/network/if-pre-up.d/wireless-tools
- sudo aptitude -R remove wireless-tools (依存関係に問題があり非推奨？)

dhcp時の問題
- CentOSと同様、dhcp時に問題が起きる
- sudo /etc/init.d/networking restart
