define Package/tcpbridge/description
  tcpbridge is a tool for selectively briding network traffic across two
  interfaces and optionally modifying the packets in between
endef

define Package/tcpcapinfo/description
  tcpcapinfo is a tool for decoding the structure of a pcap(3) file with a
  focus on finding broken pcap files and determining how two related pcap
  files might differ.
endef

define Package/tcpliveplay/description
  This program, 'tcpliveplay' replays a captured set of packets using new TCP
  connections with the captured TCP payloads against a remote host in order
  to do comprehensive vulnerability testings.
endef

define Package/tcpprep/description
  tcpprep is a ``pcap(3)'' file pre-processor which creates a cache file
  which provides "rules" for ``tcprewrite(1)'' and ``tcpreplay(1)'' on how to
  process and send packets.
endef

define Package/tcpreplay/description
  tcpreplay is a tool for replaying network traffic from files saved with
  tcpdump or other tools which write pcap(3) files.
endef

define Package/tcpreplay-edit/description
  tcpreplay-edit includes all the functionality of both tcpreplay
  and tcprewrite.
endef

define Package/tcprewrite/description
  Rewrite/edit the packets in a pcap file
endef

define Package/tcpreplay-all/description
  Tcpreplay is a suite of free Open Source utilities for
  editing and replaying previously captured network traffic.
  Originally designed to replay malicious traffic patterns to
  Intrusion Detection/Prevention Systems, it has seen many evolutions
  including capabilities to replay to web servers.

  Version 4.0.0 introduces features and performance enhancements
  to support switches, routers, and IP Flow/NetFlow appliances.
