It is commonly called as a sniffer, network protocol analyzer, and network analyzer. It is also used by network security engineers to examine security problems. Wireshark is a free to use application which is used to apprehend the data back and forth. It is often called as a free packet sniffer computer application. Wireshark can be used in the following ways: It puts the network card into an unselective mode, i.e., to accept all the packets which it receives.It is used by network security engineers to examine security problems.It allows the users to watch all the traffic being passed over the network.It is used by network engineers to troubleshoot network issues.It helps us to know how all the devices like laptop, mobile phones, desktop, switch, routers, etc., communicate in a local network or the rest of the world.Ī packet is a unit of data which is transmitted over a network between the origin and the destination.It also helps to troubleshoot latency issues and malicious activities on your network. Network packets are small, i.e., maximum 1.5 Kilobytes for Ethernet packets and 64 Kilobytes for IP packets. The data packets in the Wireshark can be viewed online and can be analyzed offline. ![]() In the late 1990's Gerald Combs, a computer science graduate of the University of Missouri-Kansas City was working for the small ISP (Internet Service Provider). The protocol at that time did not complete the primary requirements. So, he started writing ethereal and released the first version around 1998. ![]() ![]() The Network integration services owned the Ethernet trademark.Ĭombos still held the copyright on most of the ethereal source code, and the rest of the source code was re-distributed under the GNU GPL.
