# Nmap nmap payload database -*- mode: fundamental; -*-
# $Id$
#
# These payloads are sent with every host discovery or port scan probe
# by default. This database should only include payloads that are
# unlikely to crash services, trip IDS alerts, or change state on the
# server. The idea behind these is to evoke a response using a payload.
# Some of them are taken from nmap-service-probes.
#
# This collection of data is (C) 1996-2010 by Insecure.Com
# LLC.  It is distributed under the Nmap Open Source license as
# provided in the COPYING file of the source distribution or at
# http://nmap.org/data/COPYING .  Note that this license
# requires you to license your own work under a compatable open source
# license.  If you wish to embed Nmap technology into proprietary
# software, we sell alternative licenses (contact sales@insecure.com).
# Dozens of software vendors already license Nmap technology such as
# host discovery, port scanning, OS detection, and version detection.
# For more details, see http://nmap.org/book/man-legal.html
#
# Each entry begins with a protocol (only "udp" is supported) followed
# by a comma-separated list of ports, followed by one or more quoted
# strings containing the payload. These elements may be broken across
# several lines. For future expansion, additional keywords may follow
# the payload data. Any data following one of these keywords must be on
# the same line as the keyword so that unknown keywords can be ignored
# by the parser. Currently this file contains some entries with the
# "source" keyword to specify a desired source port, but it is not
# honored by Nmap.

# Example:
# udp 1234 "payloaddatapayloaddata"
#   "payloaddatapayloaddata"
# source 5678
