Wireshark: Troubleshooting in the network
Wireshark training
With around 500,000 downloads per month, Wireshark represents the de facto standard for network analysis. It can be used to record and evaluate network connections. The aim of this training is to learn a practical approach to locating network problems using the open source software "Wireshark". In addition to discussing the theoretical basics, numerous live demos provide direct insight into the approach to network analysis. Whether online or in person - various exercises allow the participants of the course to put the knowledge covered into practice immediately and to internalize what they have learned.
