I have CentOS 4 running on an old (early model) p3 with 64 MB RAM. It
is acting as a router and firewall for my LAN.
CentOS is doing a really good job with Shorewall + DHCPd - on a 10 Mbps
cable modem, I see ~ 9.7 Mbps of throughput even when numerous tcp
streams to different LAN hosts are running.
I would like to add a virtual interface to one of my LAN interfaces.
My LAN interface (/etc/sysconfig/network-scripts/ifcfg-eth2) looks like:
DEVICE=eth2
BOOTPROTO=static
BROADCAST=192.168.10.255
HWADDR=00:60:08:C3:F9:71
IPADDR=192.168.10.1
NETMASK=255.255.255.0
NETWORK=192.168.10.0
ONBOOT=yes
TYPE=Ethernet
would adding the below:
/etc/sysconfig/network-scripts/ifcfg-eth2:0
DEVICE=eth2:0
BOOTPROTO=static
BROADCAST=192.168.20.255
HWADDR=00:60:08:C3:F9:71
IPADDR=192.168.20.1
NETMASK=255.255.255.0
NETWORK=192.168.20.0
ONBOOT=yes
TYPE=Ethernet
Would this create a virtual interface eth0:0 with the IP address
192.168.20.1?
Thanks in advance.
