address and the port the server listens to. The following figure illustrates that the server listens
on port 3102.
Figure 117: TCP client/server connection
If connection is successful, a connection is established between the client and the server. In
a NETSTAT command window, a line appears illustrating that a TCP connection is found on
port 3102 with the state ESTABLISHED.
Figure 118: NETSTAT command window
The previous figure shows the client address and port in the third column,
10.1289.65.159:4817. In many environments the client is not bound to a fixed port, and
receives a random assigned port number, for example 4817.
The capability of eFR monitoring client connections of NETSTAT is oriented towards
application environments, with a persistent socket connection. For example, DECT Messenger
is an example of a software suite based upon client/server architecture, where the majority of
client modules must be connected permanently with predefined ports on the server. Typically
you must monitor the TCP clients (eDMSAPI, eCSTA, eSMS, eCAP…) modules connected to
eKERNEL on the configured ports.
