我是新的Debian，我有6（6）网卡的机器。 这是一个便宜的路由器，但Linux使ethX设备仅用于4个网卡（eth0 … eth3）：
root@dc-02:~# dmesg | grep eth [ 1.474080] 8139too 0000:00:0c.0: eth0: RealTek RTL8139 at 0xd400, 00:50:ba:ca:90:87, IRQ 19 [ 1.475862] 8139too 0000:00:13.0: eth1: RealTek RTL8139 at 0x7800, 00:c0:df:12:05:1f, IRQ 18 [ 1.477545] eth2: 100/10M Ethernet PCI Adapter at 0001d000, 00:02:44:45:01:84, IRQ 16.

那么，我怎样才能打开eth4和eth5？ 可能吗？ 非常感谢和最好的问候。
所以，当我用基于RTL8139的芯片组网卡replaceSURECOM网卡时，一切都很好。
问题真的是在司机。 非常感谢您对DerfK和Danila Ladner的build议。
这一刻只有一个问题 – 为每个NIC提供“正确的”IP。
我已经在谷歌search重命名在udev的ethX设备，并发现，我可以写由udev命名设备riles。 在Debian 7中，这个规则已经存在于/etc/udev/rules.d/70-persistent-net.rules 。 II已经为我的要求编辑了这个文件。

所以，现在 – 没有任何问题，一切正常。 我想这个问题是closures的。
