改变接口的顺序

希望有人能帮助我，我想要做的是更改 Ubuntu 12.04LTS 上的接口顺序。我们在具有三个虚拟接口的 VMWare 机器上运行 Ubuntu 服务器。

我已经阅读了如何控制网络接口的up顺序？但它似乎没有提供我们所寻找的东西。

我们遇到了一个小问题，我们正在运行的一款软件使用它找到的第一个接口作为控制接口。我们实际上需要它使用第三个接口。我们已经与供应商核实过，他们确认我们无法配置软件来指定哪个接口。不过，这是另一回事了。

当前 ifconfig 看起来像这样：

eth0      Link encap:Ethernet  HWaddr 00:0c:29:b5:dd:c1  
          inet addr:192.168.10.117  Bcast:192.168.10.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:feb5:ddc1/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:21 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:1368 (1.3 KB)

eth1      Link encap:Ethernet  HWaddr 00:0c:29:b5:dd:cb  
          inet addr:192.168.20.117  Bcast:192.168.20.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:feb5:ddcb/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:11 errors:0 dropped:0 overruns:0 frame:0
          TX packets:6 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:660 (660.0 B)  TX bytes:468 (468.0 B)

eth2      Link encap:Ethernet  HWaddr 00:0c:29:b5:dd:d5  
          inet addr:192.168.30.117  Bcast:192.168.30.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:feb5:ddd5/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:9 errors:0 dropped:0 overruns:0 frame:0
          TX packets:6 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:540 (540.0 B)  TX bytes:468 (468.0 B)

我们理想情况下希望现在的 eth2 和 MAC 为00:0c:29:b5:dd:d5eth0。当我们进行/etc/network/interfaces相应更改时，我们得到了更改，但不正确：

eth0      Link encap:Ethernet  HWaddr 00:0c:29:b5:dd:c1  
          inet addr:192.168.30.117  Bcast:192.168.30.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:feb5:ddc1/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:5 errors:0 dropped:0 overruns:0 frame:0
          TX packets:25 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:526 (526.0 B)  TX bytes:1666 (1.6 KB)

eth1      Link encap:Ethernet  HWaddr 00:0c:29:b5:dd:cb  
          inet addr:192.168.20.117  Bcast:192.168.20.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:feb5:ddcb/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:17 errors:0 dropped:0 overruns:0 frame:0
          TX packets:9 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:1246 (1.2 KB)  TX bytes:706 (706.0 B)

eth2      Link encap:Ethernet  HWaddr 00:0c:29:b5:dd:d5  
          inet addr:192.168.10.117  Bcast:192.168.10.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:feb5:ddd5/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:12 errors:0 dropped:0 overruns:0 frame:0
          TX packets:13 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:946 (946.0 B)  TX bytes:946 (946.0 B)

有人能想到改变接口顺序的方法吗？

我们相信这可以通过 VMWare 来完成，但在理想情况下，如果无需重新启动服务器就可以完成，那就太好了。

我可能问错了问题，或者问的方式不对。任何指点都将不胜感激！

正如评论中所建议的，我显然没有进行足够的搜索......:)

在我上面的例子中：

nano /etc/udev/rules.d/70-persistent-net.rules

输入以下内容，并在正确的位置输入正确的 MAC 地址：

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:b5:dd:d5", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:b5:dd:cb", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:b5:dd:c1", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"

重新启动服务器，您将看到类似以下内容：

eth0      Link encap:Ethernet  HWaddr 00:0c:29:b5:dd:d5  
          inet addr:192.168.30.117  Bcast:192.168.30.255  Mask:255.255.255.0

          RX packets:21 errors:0 dropped:0 overruns:0 frame:0
          TX packets:6 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:1260 (1.2 KB)  TX bytes:468 (468.0 B)

eth1      Link encap:Ethernet  HWaddr 00:0c:29:b5:dd:cb

          inet6 addr: fe80::20c:29ff:feb5:ddcb/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:21 errors:0 dropped:0 overruns:0 frame:0
          TX packets:6 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:1260 (1.2 KB)  TX bytes:468 (468.0 B)

eth2      Link encap:Ethernet  HWaddr 00:0c:29:b5:dd:c1  
          inet addr:192.168.10.117  Bcast:192.168.10.255  Mask:255.255.255.0
