udpreplay

udpreplay is a lightweight alternative to tcpreplay for replaying UDP unicast and multicast streams from a pcap file.

Usage

usage: udpreplay [-i iface] [-l] [-s speed] [-c millisec] [-r repeat] [-t ttl] pcap

  -i iface        interface to send packets through
  -l              enable loopback
  -c millisec     constant milliseconds between packets
  -r repeat       number of times to loop data
  -s speed        replay speed relative to pcap timestamps
  -t ttl          packet ttl
  -f fastforward  fastforward seconds, then play with normal speed
  -b              enable broadcast (SO_BROADCAST)

Example

$ udpreplay -i eth0 example.pcap
$ udpreplay -i eth0 -f 600 -s 0.1 example.pcap
