Checking for Interfaces using XMLRPC

Our builds differ in the sense that sometimes they have one interface and other times they have two. I'm having difficulty determining if a system profile has one or two interfaces. If I attempt to run this code on a system that doesn't have an eth2 interface Cheetah errors out. #if $getVar($interfaces['eth2'].get('ip_address')) != '' echo "$interfaces['eth2'].get('ip_address','') $bkuphostname $bkuphost" >> /etc/hosts #end if I've tried using $varExists, not using the $getVar and just listing the interface, and a few other variations. Each one produces the same outcome.. Any reference to eth2 will cause Cheetah to crash. Does anyone have any thoughts/ ideas on how to check what interfaces are in a system profile? Or how to accomplish this? Thanks. Rob Becker This communication is for informational purposes only.
