I'm using RedHat 7.2. Currently this is what my ifcfg-eth0 file looks like...

DEVICE=eth0
BOOTPROTO=static
IPADDR=192.168.45.15
NETMASK=255.255.255.0
NETWORK=192.168.45.0
BROADCAST=192.168.45.255
ONBOOT=yes


Here's my dilema. The information in the file saves, but, when the system boots up and I run "ifconfig eth0" nothing is there. I have to manually enter in the information even though it's in the ifcfg-eth0 file. Thoughts? Suggestions?

Thanks,

are you actually starting the network services on boot? does "/etc/init.d/network restart" work? if so, run "chkconfig --levels 35 network on" to make it start on boot. note that the ONBOOT option is only relevant for that interface, not networking as a whole.

I tried "/etc/init.d/network" and it failed. Gave me lots of error messages. Here are a few:

ERROR: Can't change MAC: interface up or not permission: Device or resource busy
/etc/init.d/network: network-functions: command not found
/etc/init.d/network: check_device_down: command not found
Current MAC: 00:0C:33:ED:21:AB...this is eth0
Faked MAC: 00:0C:33:ED:21:AB
MACs are the same!!

When I reboot the system the Current MAC and Faked MAC are different. The Current MAC address listed doesn't match any of the interfaces. The Faked MAC address listed is for eth0. I also noticed right after the "Faked MAC" line I got the following error message:

/etc/rc3.d/S10network: network-functions: command not found

I'm not sure what to do and, if you haven't already guessed, I don't have a lot of experience w/Linux.

Not sure if this has anything to do with this. In the /etc/init.d/network file I found the following line:

cd /etc/sysconfig/network-scripts
/usr/local/bin/macchanger -m 00:0C:33:ED:21:AB eth0
.network functions

thanks again for your help

are you runnign this as root? never seen macchanger before...

btw, you do realise that redhat 7.2 is VERY VERY old now, and you shoudl install somethign less than 7 years old if possible?

yes, I know 7.2 is old and yes, i'm running this as root. do you have any suggestions other than upgrading?
