I want to use E-Smith as a DNS server. Can I put in 2 Nic Cards (I have 2 subnets that need to hit this server )make this a stand alone and just use this server as DNS for my network. Does anyone know?

Tyrone,

It depends is the easy answer..

Do you want to be able to server external DNS? (to the internet) or just to 2 internal Subnets?

If the answer is two internal Subnets.. you could just try adding another IP address to your singe NIC..

Lets say that you allready have the subnet 192.168.0.* on eth0
and you want to add 192.168.1.* also.. all you do is:

ifconfig eth0:0 192.168.1.254 up

check ifconfig and you should have an eth0 and an eth0:0
eth0 will have whatever IP it had before and eth0:0 will have 192.168.1.254 or whatever you specify.

Hope that helps..

Andy that sounds nlike a very good solution. See right now we are doing an IP migration. We have 2 subnets but for security monitoring we are moving to two new subnets that are just in our building so you will not have to guess when you see an address in a traffic report.

We have 2 solaris DNS servers. I wonder if I could do the same thing to the solaris servers instead of putting up a temp e-smith server to handle this job till everything is moved over. Hummmmm. Thank you for your help.
