Heres the code snippet I've used to walk a router's MAC table: snmpwalk -v 1 -c public ${GWADDR} ipNetToMediaPhysAddress \ |grep ${IPADDR} |awk '{print $4}' ${GWADDR} is your router's IP and ${IPADDR} is the target's IP. This allows you to qets MACs in another network. Would probably only work for one hop; everything I have tried it on was only a single hop away. ------------------------------------------------------------------------------ "This electronic message transmission contains confidential or privileged information from Mount Carmel .
