Bug#706499: Ethernet with Realtek R8169 only working with IPV6

[Karsten Malcher <debian@dct.mine.nu>]

Hello Ben,

yesterday i started my tests and the system just wants to blame me.

I connected the 1000 MB card with an additional network cable and i setup the /etc/network/interfaces with

# The primary network interface 1000 MB
allow-hotplug eth0
iface eth0 inet static
        address 192.168.1.3
        netmask 255.255.255.0
        network 192.168.1.0
        broadcast 192.168.1.255

# The secondary network interface 100 MB
allow-hotplug eth1
iface eth1 inet static
        address 192.168.1.4
        netmask 255.255.255.0
        network 192.168.1.0
        broadcast 192.168.1.255
        gateway 192.168.1.1
        dns-nameservers 192.168.1.1

and rebootet.
Afterwards the R8169 card works without problem.

The problem has come like a ghost and gone like a ghost.
It's hard to say for me but - the bug can be closed.
This problem is really not reproducible.

Now i must master my routing problem - maybe the problem will come up again ...

Best regards
