===Overview===
The Ludlum Model 375 radiation monitors send out a small broadcast pact to a configurable port (55555 in our config) once a second with their current reading. This is an iptables log of that packet:
<pre>
IN=eth0 OUT= MAC=ff:ff:ff:ff:ff:ff:00:90:c2:d5:81:9c:08:00 SRC=10.0.115.200 DST=255.255.255.255 LEN=68 TOS=0x0E PREC=0xC0 TTL=207 ID=41175 PROTO=UDP SPT=55554 DPT=55555 LEN=48
</pre>

===Server set up===
The server is the (Linux) machine that it physically on the same subnet as the monitors.
<pre>
zebedee 55555:192.168.87.71:55555 -u -d
</pre>
'''-u''' is for UDP traffic. '''-d''' is don't disconnect (for debugging). The first '''55555''' is the incoming udp port. '''192.168.87.71''' is the client to connect to. The second '''55555''' is the destination port on the client.

===Client set up===
The client is the (Windows) machine that has the viewer on it.
<pre>
zebedee -s -u -d
</pre>
'''-d''' is don't disconnect (for debugging). We also want some sort of security or IP restriction.
