Debian 7 中如何配置 6 张网卡

我是 Debian 新手，我的机器有 6 个网卡。这将是一个便宜的路由器，但 Linux 仅为 4 个网卡（eth0...eth3）制作 ethX 设备：

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.
[    1.479051] eth3: 100/10M Ethernet PCI Adapter at 0001b800, 00:02:44:47:04:b0, IRQ 17.
[   15.225247] 8139too 0000:00:0c.0: eth0: link up, 100Mbps, full-duplex, lpa 0xC5E1

lspci 显示所有卡：

root@dc-02:~# lspci

00:0a.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)

那么，我该如何打开 eth4 和 eth5？有可能吗？非常感谢，并致以最诚挚的问候。

答案1

因此，当我SURECOM用基于芯片组 NIC 替换 NIC时RTL8139，一切都正常。

问题确实出在驱动程序上。非常感谢 DerfK 和 Danila Ladner 的建议。

当时只有一个问题——为每个 NIC 提供“正确的” IP。

我在 Google 上搜索了如何ethX在 udev 中重命名设备，发现我可以编写规则来通过 udev 命名设备。在 Debian 7 中，此规则已存在/etc/udev/rules.d/70-persistent-net.rules。我已根据自己的要求编辑了此文件。

所以，现在 - 没有任何问题，一切正常。我认为，这个问题已经解决了。
