+Census (formerly known as ARPING Users)
+==========
+
+This is a simplified python script which checks the available subnet for computers online and returns a list of users which are online based on their mac-address
+
+The initial idea was to find known users in the given network, now it finds and stores everyone in the given network and might try to resolve these addresses into names. This is why the name `census` is coined for the project.
+
+Return Data
+----------
+after trying to reach all hosts in the selected subnets the script spits out th e following data:
+<pre>
+    { "timestamp" : 12345678, "data" : { "ip1" : ["mac1","mac2","macn"] } 
+</pre>
+
+Census is meant to be put into a cronjob or some kind of wrapper scripts as it is currently really really (2-3 minutes) slow.
+
+SNMPWALK Command
+===============
+
+For historic reasons, this is the snmpwalk command to pull the currently  registered mac-addresses on the firewall:
+<pre>
+snmpwalk -c shammunity 10.42.0.1 1.3.6.1.2.1.3.1.1.2
+</pre>

+The connect_narf.pl script morses the IP + "connected" when a user connects to filebitchs proftpd server. 
+The disconnect_narf.pl scritp will do the obvious opposite.
+It will hopefully drive someone crazy.
+
+To make it run you need to add some lines to your proftpd config.
+I decided not to let Krebs do this as I didn't want to break your FTP Server (I know FTP is broken by default).
+The 5 necessary lines are:
+
+<IfModule mod_exec.c>
+    ExecEngine on
+    ExecOnConnect "/krebs/filebitch/connect_narf.pl %a"
+    ExecOnExit "/krebs/filebitch/disconnect_narf.pl %a"
