Hi all,

I need to be able to identify which networks are on which NICs on a
multi-homed box.

There is a program that, when given an IP, will cause the associated
NIC's leds to blink, whether or not it has a physical connection to an
ethernet cable.  Used for debugging.

Thought it was ping but I can't find any options for that.

Anybody else remember what it is?

"ethtool --identify <NICname>" or "ethtool -p <NICname>", example:

     ethtool -p eth0
     ethtool --identify eth0

ethtool -p eth-r8169
Cannot identify NIC: Operation not supported
ethtool -p eth-forcedeth
Cannot identify NIC: Operation not supported
ethtool -p eth-usbnet
Cannot identify NIC: Operation not supported


I was receiving the same results. When using -t (test) I got "Cannot test: Operation not supported".

Then, after some minutes of that, all went well.  I have no idea why.

@all, thanks
