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.

You might need to remove HWADDR line.

I'm not sure which is better to do(or if it even matters), but on my virtual interfaces I do not have "TYPE=Ethernet" or "HWADDR=..." in my config file. --Bill
Here is a really useful hint if you don't know the syntax of a config file... http://webmin.com Ryan wrote:>I have CentOS 4 running on an old (early model) p3 with 64 MB RAM.
