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.

This paper investigated the critical success factors of project implementation in Nigeria. The study is motivated by the very low success rate of project delivery in the country which has created obvious problems of economic waste and end user unsatisfaction. The study sampled the opinion of fifty selected project professionals presently working in six project sites located in Anambra, Imo and River States. An objective realization instrument developed using twelve (12) factors identified in the literature as possible drivers of success in project implementation based on the Likert five-point scale of ranking. Weighted scores of respondents to the factors were analyzed using factor analysis, while the effects of the quantified weight of the critical factors were analyzed using the regression tool. Results of the analysis among others show that Environmental factors are more critical to the success of project implementation than skills portfolio of the project team. Collective responsibility among project stakeholders is a necessary condition for successful project implementation; Ability of project professionals to generate accurate designs, cost and time estimates will minimize the negative effects of economic instability on successful project delivery. Commitment of Clients to project financing obligations is a necessary condition for contractor commitment to project plans. The recommendation is that there is need for adequate environmental scanning, monitoring and evaluation at the planning stage of projects.

The ERP system has been identified as a tool for delivering information technology (IT) services through software and other critical infrastructures using internet technologies. Given its nature as an industry-driven concept and system, this is universally accepted in industry as a tool to solve practical problems with a view to achieving an integrated enterprise information system. However, a developing country like Nigeria still faces a lot of hurdles in managing its construction supply chain. The aim of this study is to investigate the factors affecting the successful implementation of enterprise resource planning (ERP) systems in the Nigerian construction industry. After a literature search, expert input via the Delphi technique, the study identified four main factors and 21 sub-factors. The Decision-Making Trial and Evaluation Laboratory (DEMATEL) method was used to prioritise the factors and to identify the relationship that exists between the factors. The findings revealed that the key factors affecting the implementation of ERP systems are "A lot of security concerns" (T7), "The management of ERP projects is too complex" (P5) and "The inability to align the ERP solution with the business plans of the organisation" (P2). This study recommends that the findings of this work will help both local and international practitioners alike.
