 Here you can find various hacky scripts made for various purposes, that may or may not be useful. 
+
+=== pingmapper ===
+A Ruby script that uses SSH to log into each imaged node and 
+ 
+ 1. sets the data plane interface address to 192.168.x.y, where the node is nodex-y,
+ 1. pings the arbitrary address 192.168.0.1 
+ 1. fetches the HW address of each node 
+
+The output of this script is a list of [x,y] : HWaddr pairs that can be compared with the MAC address table in a switch to determine which port a node lives on. 
+The script forces the switch to populate its table by pinging the nonexistent address. The syntax is:
+
+{{{
+ruby pingmapper.rb [MAX_X] [MAX_Y]
+}}}
+
+Where the script is run from a sandbox console and MAX_X and MAX_Y are the largest x and y for a node's ID.
