.
To determine the IP address of your EAM-R(s), start Scream and open the
network control window (
+
). Key
to add a new UDP server and
enter the address
255.255.255.255
– this is a broadcast address that will be
recognised by all hosts on the network. The new server will appear in the
Servers list: click on it once to highlight it and then key
+
. This
sends a “GCFPING” packet to which all GCF servers will reply. The address of
your EAM-R will appear in the control pane as shown below:
In this case, a single acknowledgement response (GCFACKN) was received
and it came from the address
192.168.42.32
so this is the address of the
EAM-R. If there are more than one EAM-R (or other GCF servers) on the
network, multiple GCFACKN packets will be reported.
