![]() a file showing the packet details of each packet as text (showing, for each packet, the default middle pane of Wireshark).a file showing the packet summaries as text (the topmost pane of Wireshark, by default)."Text file" covers a number of text file formats, such as: inverse bounded (time intersection): Finds which packets are unique to each packet capture in a given timeįrame and saves each as a packet capture.I can save this a.pcap to text file (.txt) with wireshark GUI. This can help to identify traffic that sholud be in both packetĬaptures, but is in only one. Limts to return all frames in each pcap that are between these twoįrames. bounded (time intersection): Find the first and last frames in the frame intersection of all pcapsĪccording to their timestamp Use these two frames as upper and lower symmetric difference: Find all packets that are unique to each pcap. union: Find all unique packets found in all provided pcaps. intersection: Find all packets that two pcaps have in common. Reencode the packets in a pcap using text2pcap.ĭifference: Remove all packets that are present in one pcap from another. ![]() Apply the operation and generate a list of packets.Strip L2 and 元 headers if those options are specified.Find all unique packets by their ASCII hexdump value (and hash).To each packet capture and opens all of them in wireshark.Īll set operations require packet captures and do the following: The same method and then filter both packet captures by frame number.įinds all traffic in the bounding intersection that is unique Then find the latest packet in both using Normally, you might find an ip.id of a packetĮarly in one packet capture and search for it in the other with You know that there will be other traffic on this Pings to a remote destination and file2.pcap that should have those $ pcapgraph file1.pcap file2.pcap -inverse-bounded -wĪssume that you are looking at two packet captures: file1.pcap that has Which ones are available by running this in your python interpreter: Image formats are those supported by matplotlib on your system. If no format is specified, a graph is printed to the screen and stdout. packet capture: pcapng, pcap, cap, dmp, 5vw, TRC0, TRC1,Įnc, trc, fdc, syc, bfr, tr1, snoop OUTPUT: This program can read all files that can be read by tshark. When PcapGraph detects aĭirectory, it will go one level deep to find packet captures. (shortcut for –output pcap –output wireshark)ĮXclude empty pcaps generated by a set operationįrom being saved. Recommended for more than 10K total packets. Packet in a pcap instead of a fully-colored When graphing, show a vertical line for each The default if no output options are specified. Plot the graph with a GUI matplotlib window. Print the 10 most common frames with count, frameĪnonymize packet capture file names with fictional Output results as a file with format type. Then subtracting the intersection from each. ![]() Shortcut for applying -b to a group of pcaps and Excise packetsīetween the first and last packet in each capture Insert a dummy TTL so identical packets areįirst packet capture minus packets in allĪll packets that are shared by all packet capturesĪll unique packets across all pcaket captures.ĬOMPOUND SET OPERATIONS: -b, -bounded-intersectionįind the first and last common packets between Use if pcaps track flows across IPv4 NAT. Remove IP header and encode dummy ethernet/IP AnĪP will have Ethernet/Wi-Fi interfaces that encode Or L2 frame formats differ between pcaps (e.g. Use if pcaps track flows across layer 3 boundaries Remove layer2 bits and encode raw IP packets. Apply these operations prior to performing set operations -2, -strip-l2
