       randpkt - Random	packet generator

       randpkt [ -b <maxbytes> ] [ -c <count> ]	[ -t <type> ] <filename>

       randpkt is a small utility that creates a pcap trace file full of
       random packets.

       By creating many	randomized packets of a	certain	type, you can test
       packet sniffers to see how well they handle malformed packets.  The
       sniffer can never trust the data	that it	sees in	the packet because you
       can always sniff	a very bad packet that conforms	to no standard.
       randpkt produces	very bad packets.

       When creating packets of	a certain type,	randpkt	uses a sample packet
       that is stored internally to randpkt. It	uses this as the starting
       point for your random packets, and then adds extra random bytes to the
       end of this sample packet.

       For example, if you choose to create random ARP packets,	randpkt	will
       create a	packet which contains a	predetermined Ethernet II header, with
       the Type	field set to ARP. After	the Ethernet II	header,	it will	put a
       random number of	bytes with random values.

       -b <maxbytes>
	   Default 5000.

	   Defines the maximum number of bytes added to	the sample packet.  If
	   you choose a	maxbytes value that is less than the size of the
	   sample packet, then your packets would contain only the sample
	   packet... not much variance there! randpkt exits on that condition.

       -c <count>
	   Default 1000.

	   Defines the number of packets to generate.

       -t <type>
	   Default Ethernet II frame.

	   Defines the type of packet to generate:

       To see a	description of the randpkt options use:


       To generate a capture file with 1000 DNS	packets	use:

	   randpkt -b 500 -t dns rand_dns.pcap

       To generate a small capture file	with just a single LLC frame use:

	   randpkt -b 100 -c 1 -t llc single_llc.pcap

       pcap(3),	editcap(1)
