黑客工具介绍之DDoS攻击工具Trinoo分析
(对trinoo更进一步的分析请参阅附录E中由George Weaver of Pennsylvania State University 和 David Brumley of Stanford niversity编写的"更多的监测trinoo方法"一文。)
附录A:"ngrep"捕获的网络会话
以下是"ngrep"捕获的一个攻击会话实例:

# trinot v. 1.1
# By Dave Dittrich
#
# Send commands to trinoo daemon(s), causing them to PONG, *HELLO*
# to all their masters, exit, etc. Using this program (and knowledge
# of the proper daemon password), you can affect trinoo daemons
# externally and monitor packets to verify if the daemons are up,
# expose their masters, or shut them down.
#
# Needs Net::RawIP (http://quake.skif.net/RawIP)
# Requires libpcap (ftp://ftp.ee.lbl.gov/libpcap.tar.Z)
#
# Example: ./trinot host1 [host2 [...]]
# ./trinot -S host
# ./trinot -p password -P host
#
# (This code was hacked from the "macof" program, written by
# Ian Vitek )
require 'getopts.pl';
use Net::RawIP;
