It is used by network engineers to troubleshoot network issues.It allows the users to watch all the traffic being passed over the network.It is used by network security engineers to examine security problems.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 often called as a free packet sniffer computer application. Wireshark is a free to use application which is used to apprehend the data back and forth. It is also used by network security engineers to examine security problems. It is commonly called as a sniffer, network protocol analyzer, and network analyzer. It is used to track the packets so that each one is filtered to meet our specific needs. That will translate to a better life experience for the student who now can use those skills.Wireshark is an open-source packet analyzer, which is used for education, analysis, software development, communication protocol development, and network troubleshooting. Q: What's the ONE thing you hope learners take away from this training? My hope for each student is that they will do the labs, and as a result OWN the knowledge (on a working level). By playing around more with the technology, students will become even more familiar and comfortable with the commands, and that will translate into better skills that they can apply to a real-world network. Q: Any outside-of-the-box tips for students to get the most out of your course? Yes, students should absolutely watch and practice each and every Nugget and lab, but they could go beyond that and continue to practice and experiment - starting with the topology we build in the Nuggets and labs. Every Nugget and/or lab can be done on a personal computer using GNS3, which is an emulator for Cisco hardware. I wanted to make this very easy for anyone to do, by not requiring any external/physical routers or switches for the labs. I also included details that are important for the real world, in addition to what would be important for certification. I also wanted to make sure that I covered all the core technologies regarding the network traffic that a CCNA would be expected to know. I included the configurations used in separate files (part of the NuggetLab files) so that the learner can have access to those commands as a reference for learning the commands, as well as to use when they build their labs and put in their own configurations. Q: From a student perspective, what did you keep in mind when creating this course? The exact commands to use, in the right order, to implement the configurations. One of the challenges I faced was resisting the temptation to look at and discuss packets that were not directly related to the current Nugget. With a protocol analyzer to look at the details, it is a great way to reinforce what is really happening, as the packets never lie. It reminded me that we take a lot for granted, and often "assume" what is happening on the wire. Q: What roadblocks did you come across when creating this training, and how did you overcome them? I was surprised what I personally learned from taking a look at common protocols through the Wireshark protocol analyzer. Q: What was your favorite Nugget to create? Most of them were a BLAST! One that stands out in my mind is the HDLC Nugget, because we get to see a dual-stack router, running both IPv4 and IPv6 simultaneously. Keep reading for Keith's advice on getting the most out of this new course. The 38-video course focuses on implementing and analyzing Cisco networks, including topics such as multicast, IPv4 and IPv6, and much more. This training is designed to help students apply their knowledge and skills to real-world situations. Keith Barker recently completed his "CCNA Hands-on Labs Using Wireshark & GNS3" training course.
