We use static IP's in our environment and have a need to verify default router IP's from time to time. Can anyone recommend an extension attribute or script that would display the default router/gateway info?

You can try the following



#!/bin/sh



activeDev=$(netstat -rn | awk '/default/{print $NF}')



if [ ! -z "$activeDev" ]; then

    activePort=$(networksetup -listallhardwareports | grep -B1 "$activeDev" | awk -F': ' '/Hardware Port:/{print $NF}')

    routerIP=$(networksetup -getinfo "$activePort" | awk '/Router:/{print $NF}')



    echo "<result>$routerIP</result>"

else

    echo "<result>No active network</result>"

fi

Worked like a charm. Thanks much.
