eth0:0 is configured but not listed in ifconfig output
- by FractalizeR
Hello.
I have the following problem:
My server was given two IPs from [b]different[/b] subnets. Now I am trying to configure the system to work properly. I have created
[root@server ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper)
HWADDR=00:30:48:DA:B1:0E
DEVICE=eth0
BOOTPROTO=none
BROADCAST=79.174.69.255
IPADDR=79.174.69.241
NETMASK=255.255.254.0
NETWORK=79.174.68.0
ONBOOT=yes
GATEWAY=79.174.68.1
TYPE=Ethernet
[root@server ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0:0
# Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper)
HWADDR=00:30:48:DA:B1:0E
DEVICE=eth0
BOOTPROTO=none
BROADCAST=79.174.69.255
IPADDR=79.174.71.74
NETMASK=255.255.255.0
NETWORK=79.174.71.1
ONBOOT=yes
GATEWAY=79.174.71.1
TYPE=Ethernet
But both after "service network restart" and after "reboot"
[root@server ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:30:48:DA:B1:0E

Device eth0:0 is not shown as active. If I try
[root@server ~]# ifconfig eth0:0
eth0:0 Link encap:Ethernet HWaddr 00:30:48:DA:B1:0E
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
Memory:df220000-df240000
It is shown as up and running, but IP is not assigned to it.
Also it is strange, that IP address assigned to eth0:0 in config file is used by eth0.
/var/log/messages shows nothing about network configuration errors on either eth0 or eth0:0. system-config-network seem to understand all settings correctly and resaves them ok also.
"ifup eth0:0" executes ok, but ifconfig afterwards shows no eth0:0 device after that.
What did I do wrong? May be the problem is that IPs are from different subnets?
