我如何更改 ETH 名称？

我有一台 ubuntu 服务器 (meerkat)，由于它出现故障，我不得不更换 NIC。因此，我移除了出现故障的 NIC，并用插入服务器两个 PCI 插槽的两个 NIC 替换了它。

一切正常，只是其中一个网卡名称是 eth1-eth3。请参见下面的 ifconfig -a 结果：

eth1      Link encap:Ethernet  HWaddr xx:xx:xx:xx:50:a5
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
          Interrupt:16

eth2      Link encap:Ethernet  HWaddr xx:xx:xx:xx:50:a4
          inet addr:xxx.xxx.xxx.98  Bcast:xxx.xxx.xxx.255  Mask:255.255.255.0
          inet6 addr: fe80::204:23ff:fec8:50a4/64 Scope:Link

          TX packets:25886 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:3423836 (3.4 MB)  TX bytes:3148479 (3.1 MB)

eth3      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:51
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
          Interrupt:24 Base address:0xe800

eth1-eth3 Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:63
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0

          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
          Interrupt:28 Base address:0xec00

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

我通过 70-persistent-net.rules 搜索如何更改 NIC 名称，但得到的结果是：

# PCI device 0x1186:0x1300 (8139too)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="xx:xx:xx:xx:xx:56", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x1076 (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="xx:xx:xx:xx:xx:a4", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"

# PCI device 0x11ab:0x4361 (sky2)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="xx:xx:xx:xx:xx:a5", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

# PCI device 0x1106:0x3106 (via-rhine)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="xx:xx:xx:xx:xx:63", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth3"

# PCI device 0x1106:0x3106 (via-rhine)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="xx:xx:xx:xx:xx:51", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth3"

我如何将 eth1-eth3 更改为 eth4？为什么 Linux 将我的新网卡标记为 eth1-eth3？

答案1

在 70-persistent-net.rules 中将第二个 eth3 接口的参数更改NAME为 eth4，然后重新启动网络。

答案2

看一下ifrename。我记得它非常容易使用。

$ aptitude show ifrename

Description : Rename network interfaces based on various static criteria
 Ifrename allow the user to decide what name a network interface will have.
 Ifrename can use a variety of selectors to specify how interface names match
 the network interfaces on the system, the most common selector is the interface
 MAC address.
Site : http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html

它使用一个配置文件来告诉 udev 如何命名接口。
