Help on networking?
 

I have three different ethernet cards from three different vendors. Say I have configured three IPs on three different interfaces.Now If I ping any server how can I know which interfaces is beign used.

Uh - by the IP address returned to you by "ping"?

You didn't say whether the IP's were on the same, or different subnets.

And if you want to prefer one address over another, you can always manually configure routing (e.g. "man route").

'Hope that helps .. PSM

Can you post:

what do yu mean by "By IP address returned by "ping"
I am little confused..can yu elaborate?

You still did not tell the way you have subnetted your network. Are all the three cards configured with addresses on the same network or different?
And if you want to ping other machine from this with multiple card machine, you can either prioritize or tell ping what interface to use to ping the destination.
And if you are pinging this machine from outside, then the source can tell from the ping replies what interface is responding.

How do we prioritize?

man route.

same network

Hi,
