Purge old eth1, add new nic as eth0

10-13-2012, 11:46 AM

How can I completly remove all remnants of an old eth1
Everytime I go to add a new nic it wants to call it eth1

I will be replacing the old nic with ano identical chipped card,
which it wants to call eth1

I would prefer eth0

F17 using system-config-network
I have through s-c-n removed all hardware nic,
also removeed ~/network-scripts/ifcfg-eth*
Keeps coming back,

Where else do I look.

/etc/udev/rules.d/70-persistent-net.rules this is the only
place which matters for manual NIC-naming and ifcfg_eth*
scripts should NOT contain MAC-addresses to leave the
udev-rule the only point to assign

you need to reboot or restat udev

cat /etc/udev/rules.d/70-persistent-net.rules

Where do I find some of this info to put in the udev rule.
It's not being auto-generated.

using lshw I get:

"ifconfig --a" will show you every interface with the MAC address
only the MAC and NAME has to be changed in teh udev-rule

Check in /etc/udev/rules.d/70-persistent-net.rules

So, ifconfig returns no info about eth0, or any eth# device.

So, ifconfig returns no info about eth0, or any eth# device.

In your log file, the MAC address is 00:03:0d:15:2b:9e.
The udev rule looks for MAC address 00:03:0d:13:0b:0e.
No match, no action.
