Wireshark is a network analyzer which can be used across lots of areas and network analyzing and performance is only some of them.
The application can be used with PC's that have Windows, Mac or Linux systems and the great thing about Wireshark it is absolutely free. On the Windows platform it uses WinPcap to analyze the network and it is simple to install. Once it has been installed it has all the tools required for grabbing network packets, filtering and analyzing them. The portable version requires you to download WinPcap every time you want to use it because when you log out it gets uninstalled automatically.
This is not designed for anybody to use but for the IT professional. It requires a great deal of knowledge how the system operate and most if all understand it. The interface is split into three sections which will cover packet capture process, customization options and opening previously saved file or any documents for the product
Wireshark has the added advantage that it comes with support for wireless and Ethernet adapters and has the ability to capture others from VLANS, USB and Bluetooth network interfaces.
Wireshark has some great features and all of them are designed for valuable information to the users. It does not only make available the traffic information but is also able to give statistics related to a specific file.This will include general information as well as how many HTTP requests and responses have been connected with the file.
Wireshark is a good system and is able to work across a multitude of platforms and will give all the information that a network administrator needs. However, the amount of information that it supplies can be overwhelming but it has a filtering feature that you can arrange the information which is relevant to you. It works with both cable and wireless adapters and allows the creation of profiles to assist in quick configurations of a session.
The only negative is that the system is complicated and requires a lot of learning but it is the preferred system that IT specialists like to use. It is comparable to most network analyzers even those available at a cost and the feature that administrators like about Wireshark is that it will operate across different platforms and the information that you get is accurate.
