Then at least we will have either the address (IP or MAC) of the user or the application that he complains about or the server he is accessing. Therefore, it is important to understand what problem we are solving. Examples of configuring WireShark filters to capture trafficĪfter choosing an interface, we can either start capturing traffic in the mode - everything in a row, but this is not recommended, since, for example, at 50% load on a gigabit interface, it takes only a few milliseconds to transfer 100,000 packets. Learn how to work with filters for traffic analysis.Īs part of this article, we will focus on the penultimate point - how to set up filters to capture traffic in WireShark. Learn how to work with filters to capture traffic Study the stack of protocols and their structure If you do not have a commercial solution with built-in automatic analysis tools or an expert system, then perhaps the most correct way would be:ĭownload and install on a laptop one of the best free protocol analyzers WireShark () In the process of analyzing network or application performance problems, if your company does not have a centralized application performance monitoring system, then to analyze problems from levels 4 to 7 of the OSI network model, you will need to use a protocol analyzer (aka sniffer). Today we will look at their main examples, and show you how to set them up correctly! Most of the questions when working with the WireShark program among users are caused by filters for capturing traffic.
