Default output $capinfos wireless_080224_įile type: Wireshark/tcpdump/. It is a freeware tool that, once mastered, can provide valuable insight into your environment. Wireshark is a very useful tool for information security professionals and is thought of by many as the de facto standard in network packet and protocol analysis.

extract specific timestamp period in pcap files. Its a command-line tool that is part of the Wireshark family. Wireless_080224_ 13:10:09.637336 13:40:23.026171 Wireshark and tcpdump displayed different date and time stamps for the same PCAP file. Is there any easy way to create a pcap file for the packets related to a specific datetime range maybe using tshark. (See the help for details).Ĭapinfos does no dissection and so will be much faster than tshark. x of libpcap provides 10-6 second native resolution, however pcap format supports a larger 2 x 32-bit timestamp value for each stored packets.
However, Wireshark provides a program, capinfos, which reads a capture file to obtain information about the capture file such start-time, end-time, number-of-packets, etc.
