WebThe following code sample demonstrates capturing packet data and printing it in binary form to the screen. This sample is only for illustrating the use of the Packet Capture Library APIs. It is recommended that you write your own application for optimal function in a production environment. /* * Use pcap_open_live () to open a packet capture ... Webpcap_open_live () is used to obtain a packet capture handle to look at packets on the network. device is a string that specifies the network device to open; on Linux systems with 2.2 or later kernels, a device argument of "any" or NULL can be used to capture packets from all interfaces. snaplen specifies the snapshot length to be set on the ...

To write our packet-capturing program, we need a network interface on which to listen. We can specify this device, or use a function which libpcap provides: char *pcap_lookupdev (char *errbuf). This returns a pointer to a string containing the name of the first network ... Websnaplen public PcapHandle.Builder snaplen(int snaplen) Parameters: snaplen - Snapshot length, which is the number of bytes captured for each packet. If this method isn't called, the platform's default snaplen will be applied at build(). Returns: this Builder object for method chaining. promiscuousMode good fundamental stocks to invest
