lo and eth0 fail on boot

dsiguy · 03-13-2003, 12:23 PM

I have redhat 7.3 and I shutdown the computer so I could change a fan.

As the system was shuting down it showed the interactive shutdown and it said eth0 failed.

When I boot the PC back up it goes through the interactive startup and it says

lo Missing config file ifcfg [FAILED]
eth0 Missing config fiel ifcfg [FAILED]

i checked /etc/sysconfig/network-scripts/ifcfg-lo and/etc/sysconfig/network-scripts/ifcfg-eth0 and the file is there with all the proper info.

Does anyone have any suggestions?

Are the permissions on the files OK?
644 should be enough.

Have you tried restarting after the boot:
/etc/init.d/network stop
(^ Just to make sure it is stopped first)
Then
/etc/init.d/network start

OK well I changed the file permissions to 644 and

I still get the same result.

I rebooted the computer and lo actually booted OK but eth0 failed. I rebooted 1 more time and then they booth failed.

I took a look closer look at what the error was and thought I would see if anyone can help me with this.

Is there anyway that it is missing the ifcfg file.

I beleive that the system is really looking for the ifcfg-eth0 and ifcfg-lo but is it possible I am missing ifcfg

Thanks

One other thing.

when I run

/etc/init.d/network stop

it tells me that I am missing ifcfg [FAILED]

david_ross · 03-13-2003, 02:50 PM

ifcfg should reside in /sbin e.g.
/sbin/ifcfg

Does it exist?

dsiguy · 03-13-2003, 02:57 PM

it does exist.

I have checked it against another linux box and everything is the same. (Where it should be)

dsiguy · 03-13-2003, 02:59 PM

also the permisssion onthat is also 644

david_ross · 03-13-2003, 03:02 PM

ha ha - change the permisson to 755 - you need to be able to execute it

chmod 755 /sbin/ifcfg

Sorry - my second test proved inconclusive it may not be that problem?

Try installing iproute-2.4.7-1.i386.rpm

Download
ftp://rpmfind.net/linux/redhat/7.3/e...4.7-1.i386.rpm
Then enter the command "rpm -ivh /path/to/iproute-2.4.7-1.i386.rpm"

I really do appreciate all your help.

Now I only get an error on the lo but the eth0 does not even say it attempted to start.

david_ross · 03-13-2003, 03:40 PM

Can you give me the EXACT messages from the moment you type
/etc/init.d/network restart
until it finishes

It is much easier to see what is happening

# /etc/init.d/network restart

Shuttingdown interface eth0 [OK]
Missing config file ifcfg

Setting Network Paramaters [OK]

Bringing up interface lo: Missing config file ifcfg. [FAILED]

mmm - odd that it should try to shut down eth0 and not try to bring it back up!

How about recreating the config files?

Stop the network first:
/etc/init.d/network stop

1) "mv /etc/sysconfig/network-scripts/ifcfg-eth0 /root/"
2) "mv /etc/sysconfig/networking/ifcfg-lo /root/"
3) "vi /etc/sysconfig/networking/ifcfg-lo"
enter:

Code:

DEVICE=lo
IPADDR=127.0.0.1
NETMASK=255.0.0.0
NETWORK=127.0.0.0
# If you're having problems with gated making 127.0.0.0/8 a martian,
# you can change this to something else (255.255.255.255, for example)
BROADCAST=127.255.255.255
ONBOOT=yes
NAME=loopback

4) "mv /etc/sysconfig/network /root/"
5) "vi /etc/sysconfig/network"
enter:

Code:

NETWORKING=yes
HOSTNAME=YOURHOST
GATEWAY=YOUR.GW.GOES.HERE

and change YOURHOST and YOUR.GW.GOES.HERE

6) "netconfig"
7) enter your network info

Then start the network:
/etc/init.d/network start

I have not tried the last suggestion but I am thinking that something else maybe wrong now.

When booting up it seems to hang in serverl places at diferent times:

Sometimes when shutting down

NFS fails.

But i will try your suggestion now
