Are the scripts not running? Scripts? Brian's scripts that push out new configs upon IP change. I don't have brians scripts, and I'm using a config tool based on netconf/yang to configure my routers. A Yang model for HECNet, anyone? Meanwhile, if anyone need me to change a tunel on a box I hapens to operate, send me a email with the needed info. (Why do addresses change? T10 nor T20 speak DHCP or ND?) -P
