![]() ![]() ![]() We can even do this inverse of this and filter out the specific IP Filtering Out (Excluding) Specific IP in Wireshark This expression translates to “pass all traffic with a source IPv4 address of 192.168.2.11 or a destination IPv4 address of 192.168.2.11.”Īs you can see the packets displayed in the Packet List Pane all contain 192.168.2.11 in either the source or the destination column. Use the following display filter to show all packets that contain the specific IP in either or both the source and destination columns: ip.addr = 192.168.2.11 Related: Wireshark User Interface (GUI) Overview Filtering Specific IP in Wireshark It’s also possible to filter out packets to and from IPs and subnets.īeyond that, you can use IP filters as both capture filters (only capture packets based on the filter) and display filters (filter the display of captured packets). We can filter to show only packets to a specific destination IP, from a specific source IP, and even to and from an entire subnet. With Wireshark we can filter by IP in several ways. One of the most common, and important, filters to use and know is the IP address filter. This amounts to a lot of data that would be impractical to sort through without a filter.įortunately, filters are part of the core functionality of Wireshark and the filter options are numerous. Unless you’re using a capture filter, Wireshark captures all traffic on the interface you selected when you opened the application. You can also find a walkthrough video from Chris himself on Youtube.The ability to filter capture data in Wireshark is important. This was the first part of our series about this packet analysis room. Click on this link to open the interactive analysis.Ĭlick on next in the bottom overlay or the play button in the navigation bar to go to the next solution. One cool feature of PacketSafari is to document your analysis right within the PacketSafari app. So this filter will do fine icmp.type = 0, ending up with 16 packets. The last question is about ICMP Echo replies. It works similar for udp: udp and not icmp. Using the filter tcp and not icmp we can answer with the correct number of 5269. As you might now ICMP can quote certain packets which happens quite often with destination unreachable packets. And the non-ICMP packets not icmp with a total of 6310 packets and TCP packets tcp with 6293.Ī more interesting filter again is TCP packets that are not encapsulated in ICMP. The number of ICMP packets is again very straightforward icmp with a total of 1064 packets. Finally, at the bottom, we can find the source mac address and copy it using right-click -> copy. The source column shows the correct IP address. In the screenshot, we can see the applied filter. First, we filter for the requested IP address ip.src =192.168.56.1. Now, the third question is a bit more interesting as we need to filter first and then look at the packet details in the lower left part of the screen. The second question we can solve similarly by applying the filter ip with a matching 6342 packets. The following link directly solves the first question: solution to first question Solving the other questions One cool feature of PacketSafari is the possibility to link directly to a filtered PCAP. If you have a PacketSafari account you can also change the default limit of 1000 to a higher value. You can of course load all matching packets by clicking on Load all matching packets. This is an optimization for the application to be more responsive. PacketSafari currently displays only 1000 of these packets. Looking a bit closer we can see that there are 1032 matching packets. Applying the filter arp we can answer that question easily. The first question asks about the number of ARP packets in the trace file: How many ARP packets are in this pcap?. You can open the PCAP directly in your browser using PacketSafari. Let's try to solve it using PacketSafari. The first part of the room is about applying simple protocol filters. PacketSafari offers some advanced features and tools for analyzing and visualizing network traffic, which can make solving a Wireshark filter room more enjoyable and effective. PacketSafari is a cloud-based application, which means you can access it from any device with an internet connection, making it very convenient to use. PacketSafari is also meant to be a public archive of PCAPs and analysis for educational purposes. This can be especially useful if you are working on a device that doesn't have Wireshark installed or need the necessary permissions to install it. It allows you to easily and quickly analyze network traffic without installing and setting up Wireshark on your local machine. Solving the TryHackMe Wireshark Filter room with a SaaS application like PacketSafari can be very convenient. ![]()
