Kali Linux Wireshark provides a good display and network packets to display their content so th...
I have a machine running Wireshark in promiscuous mode, but I'm unsure how to analyze the results. Is this a job for something like Snort? Are there some commands on the router or core switches that I could be running to give me some clues? I realize locking down ethernet ports, ...
In this article, we’ll show how to enable DNS logging for all user queries on a DNS server running Windows Server, how to parse and analyze DNS logs. I faced this task when I had to decommission an old Active Directory domain controller in a branch office and I needed to understand wh...
To start capturing packets, we right-click "enp0s3," and then select "Start Capture" in the context menu. You can set filters to reduce the amount of traffic Wireshark captures. We prefer to capture everything and filter out anything we don't want to see when doing an analysis. This ...
Hide capture info dialog:Disable this option so that you can view the count of packets being captured for each protocol. Enable MAC name resolution:Wireshark contains a table to resolve MAC addresses to vendors. Leave enabled. Enable network name resolution:Wireshark will issue DNS queries to re...
