Network Alias and multiple networks on 1 NIC

Stratus_ss · 04-20-12, 02:03 PM

So I have this laptop which is serving as my local repository. I recently wanted to spin off a network for Virtual Machines (.122.*). Running Centos 6.2 I tried putting these in /etc/sysconfig/network-scripts

ifcfg-eth0

Code:

HWADDR=00:08:74:3E:86:30
DEVICE=eth0
TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.99.247
PREFIX=24
GATEWAY=192.168.99.253
DNS1=192.168.99.253
DOMAIN=stratus-sphere
IPV6INIT=no
ONBOOT=yes

ifcfg-eth0:1

Code:

DEVICE=eth0:1
BOOTPROTO=static
IPADDR=192.168.122.247
PREFIX=24
GATEWAY=192.168.122.233
DNS1=192.168.122.233
DOMAIN=stratus.local
ONBOOT=yes
HWADDR=00:08:74:3E:86:30

No matter what I do, it will only activate one or the other and not both. I have followed the Red Hat docs, as well as online guides and this should be all I need to do with what I have read.

Anyone have any pointers?

The virtual nic should be named ifcfg-eth0:1

Rename the config file, restart the network, and run ifconfig. The virtual interface should be listed.

I've used this method before, looks slightly different than what you are doing: http://blog.rackwire.com/2010/05/how...ans-in-centos/

I tried this (though that wasn't clear in my first post). This is how it is currently set. It still only activates the one IP

Splat, Thanks for that I will give that a try!

The vlan suggestion worked.

I needed to append

Code:

VLAN=yes

Inside of my eth0.122 and eth0.99. Thanks!
