To capture various types of IPv6 traffic: ip6 dst host ff02::1 To capture traffic from a specific URL or host: host To exclude a specific type of traffic: not port 23 not arp To capture traffic from a specific port or range of ports: port 23 portrange 1-1024 tcp portrange 1-1024 UDP port 167 UDP portrange 1-1000 To capture traffic from a specific host: host 10.0.6.187 Capture FiltersĬapture filters allow you to capture specific types of traffic, this prevents the capture of packets you don’t want, thus not wasting valuable processing power and hard drive space. This workshop is an introduction to network conversation statistics, threat hunting, and carving documents from. At a minimum, you should understand capture filters, display filters, profiles, and how to filter for different services as well as identifying IPv6 traffic. Wireshark is a tool every security professional should be comfortable with. The most popular packet analyzer is Wireshark, so let’s take a look at how it works and how to use it. Packet analyzers can take a file of captured data (known as a pcap file) and examine it in various ways to tell us more about the traffic between different machines on a network. One of our primary tools for passive/active information gathering is a program called a protocol analyzer or packet analyzer.
