Linux eth0이 안되고 eth1로 네트워크가 잡히는 경우

해결 방법

◆ 다음과 같이 eth0이 안잡히고 eth1이 잡히는 이뉴는 udev와 관련이 있다

◆ 문제의 원인은 /etc/udev/rules.d/70_persistent-net.rules

# This file was automatically generated by the /lib/udev/write_net_rules

# program run by the persistent-net-generator.rules rules file.

#

# You can modify it, as long as you keep each rule on a single line.

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE] (rule written by anaconda)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:79:8b:58", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

# PCI device 0x1022:0x2000 (pcnet32)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:60:3c:8c", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

- 이렇게 되어있는데 위의 경우 MAC Address가 틀려서 재설정 한 것으로 보인다. 결론은 이 파일을 지워주면 된다. 지위준후 roboot 후 파일을 보면

# This file was automatically generated by the /lib/udev/write_net_rules

# program run by the persistent-net-generator.rules rules file.

#

# You can modify it, as long as you keep each rule on a single line.

# PCI device 0x1022:0x2000 (pcnet32)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:60:3c:8c", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

- 이렇게 다시 잡혀있는것을 알수 있다. 그렇게 한후

/etc/sysconfig/network 설정, /etc/sysconfig/network-scripts/ 설정후 reboot
