This paper presents the full implementation of the Psniffer application software that captures
network data as well as provides sufficient means for the decision making process of an administrator.
The aim of this application is to rewrite C language sniffer into Java, and also develop an
application that consumes little memory on the hard disk. This work illustrates the requirement
needed to design a new application; it was developed in Java and it consumes little memory on
the hard disk. This application comprises of five independent modules that handles different tasks
efficiently. This program can monitor network traffic, analyzes traffic patterns, identify and troubleshoot
network problems. This application does not transmit any data onto the network, uses
1MB of the hard disk space, friendly GUI and it is very easy to install.
