# 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 # GenericLines.
