Question Multiple IPV4 addresses not working after boot, works after network restart


Fedora 12 running under VirtualBox 3.2.8 w/ Bridged networking
Host OS Windows 7

I have 3 IP addresses set up in on my Fedora 12 installation:
Directory: /etc/sysconfig/network-scripts/
ifcfg-eth0 -> 192.168.0.170
ifcfg-eth0:0 -> 192.168.0.171
ifcfg-eth0:1 -> 192.168.0.172

Hostname is configured to host associated with 192.168.0.170 in /etc/hosts

When I reboot and execute

# ifconfig

eth0 is associated with the 172 address and the other addresses are not active. After I run

# service network restart

All of the addresses are active and associated with the correct interfaces.

Any hints on where to look for the problem?

Content of my ifcfg files below:

/etc/sysconfig/network-scripts/ifcfg-eth0 :
Code:
# Intel Corporation 82540EM Gigabit Ethernet Controller

I would try wiping out the existing configs and recreating them.

Make a backup of the originals first.

/var/log/messages

You could also put
Code:
/etc/init.d/network restart
in /etc/rc.local so that the network will restart upon reboot.

Thanks to rhbegin and valen_tino for suggestions.

I tried removing and re-creating the
/etc/sysconfig/network-scripts/ifcfg-{eth0,eth0:0,eth0:1}
files and that didn't work.

Adding /etc/init.d/network restart to /etc/rc.local
would have solved the issue; but I would have learned nothing from
the exercise.

The problem was that the NetworkManager service was enabled
and the network service was not. I failed to realize this
when I decided to experiment with IP alaises. With NetworkManager
off and network on, life after reboot is sweet!
