two network cards in system

[Oh Chakravu]

Hi,

I have installed two network cards in my system and need to know how I can
configure them so that one of them is used for private network and the
other for public?

Also, everytime I reboot my system, I have to start network interface
manually...how can I set them so that startup at bootup time?

Thanks in advance for your help..

if possible, please cc to: [email]achana@yorku.ca[/email]

Errm, configure the IP addresses on the cards, one for the public and
one for the private, using smitty chinet.

If you want the machines communicate over the private network, you can
overwrite the ip addresses resolved by DNS in /etc/hosts and then change
the lookup order with a line "hosts=local , bind" in a file
"/etc/netsvc.conf"
By default AIX uses DNS before hosts file.

These two networks will invariably have different ip address ranges,
i.e. be two different subsets. Private, say 192.168.1.x and your
bpulic one dictated by your ISP.

So using one card for each network is just as simple as assigning an
appropriate IP address and subnet mask to each.

One example: set one nic to use DHCP to get it's address from your
ISP, and statically assign your private nic to something in teh
address range you assign to your private network, 192.168.x.x 10.x or
what have you.

Learning more about basic networking, IP addresses and subnet masks
will help you a lot.

Use "smitty inet" or "smitty mktcpip" instead of using ifconfig.

On AIX, ifconfig doesn't "stick" but using smitty gets it into the
configuration database so it survives a reboot.
