Como configurar 6 placas de rede no Debian 7

Question

Eu sou novo no Debian e tenho uma máquina com 6 (seis) placas de rede. É um roteador barato, mas o Linux faz dispositivos ethx apenas para 4 placas de rede (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.
[    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

o lspci mostra todos os cartões:

root@dc-02:~# lspci
 . . .
00:0a.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)

00:0e.0 Ethernet controller: MYSON Technology Inc SURECOM EP-320X-S 100/10M Ethernet PCI Adapter
 . . .

Então, como posso ativar eth4 e eth5? É possível? Muito obrigado e cumprimentos.

    

Answer 1

Então, quando substituí o NIC do SURECOM NIC pelo chipset RTL8139 , tudo estava bem.

O problema realmente estava nos drivers. Muito obrigado por conselhos para DerfK e Danila Ladner.

Apenas um problema ocorreu naquele momento - para fornecer IP "correto" para cada NIC.

Eu pesquisei no google por renomear ethX devices no udev e descobri que posso escrever riles para nomear dispositivos pelo udev. No Debian 7, essas regras já existem em /etc/udev/rules.d/70-persistent-net.rules . Eu editei este arquivo para minhas necessidades.

Então, agora - não há problemas e tudo funciona bem. Eu acho que esta questão está encerrada.
