The criterion is of the form test : value, where test is one of:ĭuration: value Stop writing to a capture file after value seconds have elapsed.

Specify a criterion that specifies when Dumpcap is to stop writing to a capture file.

The capture filter syntax follows the rules of the pcap library. Packet capturing is performed with the pcap library. If the -w option is specified, Dumpcap writes to the file specified by that option. If the -w option is not specified, Dumpcap writes to a newly created pcap file with a randomly chosen name. Without any options set it will use the libpcap, Npcap, or WinPcap library to capture traffic from the first available network interface and writes the received raw packet data, along with the packets' time stamps into a pcap file. When the -P option is specified, the output file is written in the pcap format. Dumpcap's default capture file format is pcapng format. It lets you capture packet data from a live network and write the packets to a file.
