+netbeacon - monitoring your network capture
+===========================================
+
+netbeacon is a set of free software tools to send beacons over
+the network to test the accuracy and the precision of your network
+capture framework. With netbeacon you can test the following properties
+of your network capture (e.g. for honeypot packet data capture,
+data interception devices, NIDS, DPI ...):
+
+- How long it takes for a packet to reach your monitoring.
+- Time inconsistencies between devices.
+- Finding missing packets or its (re)ordering.
+- Watchdog to verify an operational network capture.
+
+netbeacon - packet format
+-------------------------
+
+The netbeacon format is a simple ASCII format encapsulated in an UDP
+packet. The format is the following:
+
+header;epoch;sequence;hmac
+
+The current header is nb
+The epoch value (in UTC format)
+The sequence an unsigned integer
+and the HMAC-SHA1 signature.
+
+Each message is encapsulated in UDP and by default using port 12345.
+
+A pre-shared key (PSK) is agreed between the netbeacon sender
+and netbeacon recipient to ensure packet integrity using HMAC (SHA1).
+There is a default key "netbeacon" but we highly recommend to set your
+own for your systems.
+
+sample netbeacon messages
++++++++++++++++++++++++++
+
+Here is a serie of 3 netbeacon messages extracted from 3 UDP packets:
+ 
+        nb;1354960619;101;335540bf3dae684c3d5cd5795fd09b9097bad656
+        nb;1354960619;102;56fc82c066644f179b58eb84a47e577bf92adc47
+        nb;1354960619;103;854207f54c1c4be97bdf4cd4a0d1068731848698
