Aliased IPs

[Oliver]

look  at  the  /etc/sysconfig/network-scripts/ifup-aliases script, whether
it's configured correct.

at me, the interface config files look like this...

DEVICE=eth0:x
BOOTPROTO=static
BROADCAST=xxx.xxx.xxx.xxx
HWADDR=xx:xx:xx:xx:xx:xx
IPADDR=xxx.xxx.xxx.xxx
NETMASK=xxx.xxx.xxx.xxx
NETWORK=xxx.xxx.xxx.xxx
ONBOOT=yes
TYPE=Ethernet
