Classes
		builtins.object Sniffer   class Sniffer(builtins.object)     Sniffer(packet_printer: PacketPrinter.PacketPrinter, filter_: str = None, savefile: str = None, filetoread: str = None, iface: str = None, **kwargs)   This class sniffs, filters and saves packets.     Methods defined here: __init__(self, packet_printer: PacketPrinter.PacketPrinter, filter_: str = None, savefile: str = None, filetoread: str = None, iface: str = None, **kwargs) Initialize self.  See help(type(self)) for accurate signature. get_iface(self) -> scapy.interfaces.NetworkInterface This function get a NetworkInterface from iface arguments (a string of IP or MAC address or interface name). start(self) -> None This function starts the network sniffer. stop(self) -> None This function stops the sniffer and writes the pcap file to save the package. Data descriptors defined here: __dict__ dictionary for instance variables (if defined) __weakref__ list of weak references to the object (if defined)

Functions
		main() -> None This function start the network sniffer from the command line.
