[SOLVED] ifup "[blank] does not seem to be present, delaying initialization"

I get an odd error message when trying to bring up my network/eth :-

# service network restart
Shutting down loopback interface:  [  OK  ]
Bringing up loopback interface:  [  OK  ]
 does not seem to be present, delaying initialization.

Anyone got any ideas?

This could be caused if you have an old network configuration, perhaps your system was upgraded from an earlier version of your distribution, or maybe you've changed or removed some other network card in the past.

Whatever the cause, you can probably solve this by running 'system-config-network' (or, in text mode from the command line 'system-config-network-tui') and deleting any spurious/old/out of date interfaces it lists.

I do only get this error after a scripted kickstart of which I copy (overwrite) some system files, including ifcfg-eth0 & 1.
(HWADDR was wrong once, then left blank for next try, then set correctly, wouldnt of thought that would have anything to do with this?)
The date/time are all messed up due to no clock, couldnt be this?

Other files I copy are nothing to do with networking (as far as I belive!)
grub/smb/rc.init

Thanks for your help, I will look into this more when at work tomos.

If the HWADDR is listed in the ifcfg file, then CentOS is going to consider that interface "missing" if there is no NIC in the system with that MAC address.

And there is the 70-persistent-net.rules udev rule.

Thats very intresting, thanks.

As I am setting up many computers, all with the same networking info (private/closed systems).
So I setup the ifcfg-eth0/1 and commented out the HWADDR, and saved this to copy once the new system is installed.
When I got this error, I put the correct HWADDR in, and it still occured? Which was odd. But now we belive it is related to this, I will ensure this is correct before trying to engage the network.

Many thanks.

It was the HWADDR field missing (I have 2 nics on this board)!

Once inplace it worked just great!

Many thanks.
