+# DESCRIPTION
+#
+# This shell script takes care of starting and stopping Planetlab
+# Ping-Of-Death.
+#
+# The Planetlab POD is a Linux kernel patch that creates the feature
+# of resetting and rebooting a computer when a particularily
+# formatted ICMP "ping" commmand is received.
+#
+# A PlanetLab node's kernel gets a host, mask and hash value through
+# sysctl's that are performed on the node.  The node then looks
+# for an ICMP packet from a host matching the host/mask and, if the
+# packet payload is the hash value, the node forces an immediate
+# reboot.
+#
+# HISTORY
