Hi, I want to know how to get the IP interface index. I assume it should be something like eth0/eth1 on linux. But not sure. My question: What is IP interface index of a perticular Ethernet interface means? How to get this detail programmatically on LINUX/WIN NT?

To get the interface name on a linux box type: ifconfig On Windows, you can either view the properties of "My Network Places" (XP), or open a command prompt window and type: ipconfig /all I'm not sure what you mean by index but those will show you the "name" of the interface.

I forgot to add, for more detailed info on the a) ifconfig command type: man ifconfig b) ipconfig command type: ipconfig /?

ipconfig /all | findstr /i "description" "Computer security." — Oxymoron

Depends on the distro and the card and driver. You would need to know more about each. A very general rule is that eth0 would be the onboard while eth1 is the first adapter. Even different distro's use ifconfig a bit differently. I read it wrong and answer it wrong too. So get off my case you peanut.
