Hi all,
Our intranet's WAN interface just stopped working yesterday, and I
can't figure it out.
The machine has a Gigabyte motherboard, with on-board
RTL-8110SC/8169SC Gigabit Ethernet and D-Link PCI NIC for the LAN
side. I can get into the LAN side without an issue, but can't see the
WAN side at all.
[root@intranet ~]# ifconfig eth0 up

[root@intranet ~]# lsmod | grep 8169
r8169 77125 0
mii 38849 1 r8169
So the driver is there, or so it seems. rmmod r8169 dropped both NIC's
and I had to reboot the (headless) server to get the D-Link working
again.
Removing, and re-adding the eth0 interface with system-config-network
doesn't actually re-create the NIC either.
So, how do I re-create it? Google search didn't reveal much, other
that using the r8169 module, which is already loaded.
No changes were made to the server in a long time, that I know of, and
it's running kernel 2.6.18-194.11.4.el5
[root@intranet ~]# uname -a

[root@intranet ~]# cat /etc/redhat-release

Here's something interesting though:
