It's a udev problem (feature) - you''ve changed your network MAC and udev
thinks the new MAC is a new device. Check the sticky note in
Other Things Gentoo as a starting point for a fix.

Try this:
| Code: | | udevadm trigger net |
That should regenerate the persistent net rule.
Cheers!

Hi
Ok i entered the command | Code: | | udevadm trigger net |
and then rebooted
I had same problem ie no eth0 although simple enough to solve with ifconfig as before.
One thing tho i do now have 70-persistent-net.rules in /etc/udev/rules.d/
And looking at that file with an editor my eth0 and eth1 seem to be correctly specified at least mac adress is correct for each nic.
Could someone elaborate as to what i should do /edit to enable my eth0 at boot.
Thanks for everyones help thus far .

Hi
If i enter
# rc-update add net.eth0 default
I get the response:
* rc-update: service `net.eth0' does not exist
if i enter rc-update show sure enough eth1 and lo but no eth0
incidentally my /etc/conf.d/net shows eth0 as default even though rc-update show, gives eth1 as default
Does this give anyone a clue as to what is going on

Also, can you post this :
| Code: |
# ifconfig -a
# cd /etc/init.d/ && ls -la
|

does /etc/init.d/net.eth0 exist?
else try:
| Code: |
su
cd /etc/init.d/
ln -s net.lo net.eth0
|
If this gets you connected: (you have to be disconnected first & eth0 must be disabled else it could fail.)
| Code: | | /etc/init.d/eth0 start |
do
| Code: | | rc-update add net.eth0 boot |

Hi Guys thanks for all your help
It turned out Bzub got it , somehow eth0 had been knocked out of booting up during one
of the upgrades i probably skimmed over an etc-update to quickly.
Ah well all fixed now.
| Code: | | rc-update add net.eth0 boot |
fixed the prob permanently.
So thanks for that your a star.

Hi
I have compiled the amd64 kernel 2.6.27-r7,
and now i have no more eth0.
On my old kernel lspci said | Code: | | 01:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5751 Gigabit Ethernet PCI Express (rev 01) |
and dmesg said | Code: | eth0: Tigon3 [partno(BCM95751) rev 4001 PHY(5750)] (PCI Express) 10/100/1000Base-T Ethernet 00:e0:81:54:00:8a
eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] WireSpeed[1] TSOcap[1]
eth0: dma_rwctrl[76180000] dma_mask[64-bit]
tg3: eth0: Link is up at 1000 Mbps, full duplex.
tg3: eth0: Flow control is on for TX and on for RX. |
so i selected both | Code: | --- Network device support
--- Ethernet (1000 Mbit)
<*> Broadcom Tigon3 support
<*> Broadcom NetXtremeII support |
in the menuconfig
rc-update shows that net.eth0 gets started at boot time,
and i *do* have a 70-persistent-net.rules: | Code: | # This file was automatically generated by the /lib64/udev/write_net_rules
# program run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single line.
# PCI device 0x14e4:0x1677 (tg3)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:e0:81:54:00:8a", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" |
but still, during boot i get the message | Code: | Starting eth0
Bringing up eth0
130.60xxx.xxx
network interface eth0 does not exist.
Please verify hardware or kernel module
|
Now, i'm sure it's not a hardware problem, since it works when i boot with the 24 kernel.
How do i "verify" the kernel module?
I'm thankful for any helpful hints.
