can't activate eth0

[Richard Reina]

I am running Centos 5.4 on a few machines here. Yesterday I used /usr/sbin/setup to switch back from dhcp to a static IP on a private LAN. When I did a /etc/init.d/network restart I get:


fgrep: ifcfg-ifcfg-eth0: No such file or directory
fgrep: ifcfg-ifcfg-eth0: No such file or directory
/etc/init.d/network: line 247: ifcfg-ifcfg-eth0: No such file or directory
Shutting down loopback interface: [ OK ]
bringing up loopback interface [ OK ]
fgrep: ifcfg-ifcfg-eth0: No such file or directory
fgrep: ifcfg-ifcfg-eth0: No such file or directory
fgrep: ifcfg-ifcfg-eth0: No such file or directory
fgrep: ifcfg-ifcfg-eth0: No such file or directory
Bringing up interface ifcfg-eth0: ./ifup configuration for ifcfg-eth0 not found.

I have googled around but still have not been able to solve. Any help would be appreciated as it would likely save my Easter weekend with my family.

Thanks,

Richard -

I believe most of those msgs are coming from /etc/init.d/network.
The pattern fgrep is complaining about (ifcfg-ifcfg-eth0) looks odd. I
would expect something like ifcfg-eth0.
I believe it should be looking for file names of the network config
files in /etc/sysconfig/network-scripts.

Take a look at /etc/init.d/network around line 45. This should become a

interfaces=$(ls ifcfg* | \
LANG=C sed -e "$__sed_discard_ignored_files" \
-e '/\(ifcfg-lo\|:\|ifcfg-.*-range\)/d' \
-e '/ifcfg-[A-Za-z0-9\._-]\+$/ { s/^ifcfg-//g;s/[0-9]/
&/}' | \
LANG=C sort -k 1,1 -k 2n | \
LANG=C sed 's/ //')

Those errors are probably coming from about line 97. This is also where

# bring up all other interfaces configured to come up at boot time
for i in $interfaces; do
unset DEVICE TYPE SLAVE
eval $(LANG=C fgrep "DEVICE=" ifcfg-$i)
eval $(LANG=C fgrep "TYPE=" ifcfg-$i)
eval $(LANG=C fgrep "SLAVE=" ifcfg-$i)

Try adding an echo after the line where interaces gets set. On my
system I end up with this: 'interfaces=eth0'.
Hopefully that will point you a little closer to a solution.

best,

Okay, this may be obvious, but the script is being called w/ "ifcg-eth0"
instead of just "eth0" so it's not finding the config file to look
through. Here, in the /etc/sysconfig/network-scripts, running that ls|sed
mess [1]
$ ls ifcfg* | \
LANG=C sed -e "$__sed_discard_ignored_files" \
-e '/\(ifcfg-lo\|:\|ifcfg-.*-range\)/d' \
-e '/ifcfg-[A-Za-z0-9\._-]\+$/ { s/^ifcfg-//g;s/[0-9]/ &/}' | \
LANG=C sort -k 1,1 -k 2n | \
LANG=C sed 's/ //'

gets a list of network devices
eth0
eth1

from:
ifcfg-eth0
ifcfg-eth0:1
ifcfg-eth0:2
ifcfg-eth0:3
ifcfg-eth1
ifcfg-lo

so you may have a
ifcfg-ifcfg-eth0

file in there.
