/***************************************************************************
* nmap.cc -- Currently handles some of Nmap's port scanning features as *
* well as the command line user interface. Note that the actual main() *
* function is in main.cc *
* *
***********************IMPORTANT NMAP LICENSE TERMS************************
* *
* The Nmap Security Scanner is (C) 1996-2012 Insecure.Com LLC. Nmap is *
* also a registered trademark of Insecure.Com LLC. This program is free *
* software; you may redistribute and/or modify it under the terms of the *
* GNU General Public License as published by the Free Software *
* Foundation; Version 2 with the clarifications and exceptions described *
* below. This guarantees your right to use, modify, and redistribute *
* this software under certain conditions. 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, version detection, and the Nmap Scripting Engine. *
* *
* Note that the GPL places important restrictions on "derived works", yet *
* it does not provide a detailed definition of that term. To avoid *
* misunderstandings, we interpret that term as broadly as copyright law *
* allows. For example, we consider an application to constitute a *
* "derivative work" for the purpose of this license if it does any of the *
* following: *
* o Integrates source code from Nmap *
* o Reads or includes Nmap copyrighted data files, such as *
* nmap-os-db or nmap-service-probes. *
* o Executes Nmap and parses the results (as opposed to typical shell or *
* execution-menu apps, which simply display raw Nmap output and so are *
* not derivative works.) *
* o Integrates/includes/aggregates Nmap into a proprietary executable *
* installer, such as those produced by InstallShield. *
* o Links to a library or executes a program that does any of the above *
* *
* The term "Nmap" should be taken to also include any portions or derived *
* works of Nmap, as well as other software we distribute under this *
* license such as Zenmap, Ncat, and Nping. This list is not exclusive, *
* but is meant to clarify our interpretation of derived works with some *
* common examples. Our interpretation applies only to Nmap--we don't *
* speak for other people's GPL works. *
* *
* If you have any questions about the GPL licensing restrictions on using *
* Nmap in non-GPL works, we would be happy to help. As mentioned above, *
* we also offer alternative license to integrate Nmap into proprietary *
* applications and appliances. These contracts have been sold to dozens *
* of software vendors, and generally include a perpetual license as well *
* as providing for priority support and updates. They also fund the *
* continued development of Nmap. Please email sales@insecure.com for *
* further information. *
* *
* As a special exception to the GPL terms, Insecure.Com LLC grants *
* permission to link the code of this program with any version of the *
* OpenSSL library which is distributed under a license identical to that *
* listed in the included docs/licenses/OpenSSL.txt file, and distribute *
* linked combinations including the two. You must obey the GNU GPL in all *
* respects for all of the code used other than OpenSSL. If you modify *
* this file, you may extend this exception to your version of the file, *
* but you are not obligated to do so. *
* *
* If you received these files with a written license agreement or *
* contract stating terms other than the terms above, then that *
* alternative license agreement takes precedence over these comments. *
* *
* Source is provided to this software because we believe users have a *
* right to know exactly what a program is going to do before they run it. *
* This also allows you to audit the software for security holes (none *
* have been found so far). *
* *
* Source code also allows you to port Nmap to new platforms, fix bugs, *
* and add new features. You are highly encouraged to send your changes *
* to nmap-dev@insecure.org for possible incorporation into the main *
* distribution. By sending these changes to Fyodor or one of the *
* Insecure.Org development mailing lists, or checking them into the Nmap *
* source code repository, it is understood (unless you specify otherwise) *
* that you are offering the Nmap Project (Insecure.Com LLC) the *
* unlimited, non-exclusive right to reuse, modify, and relicense the *
* code. Nmap will always be available Open Source, but this is important *
* because the inability to relicense code has caused devastating problems *
* for other Free Software projects (such as KDE and NASM). We also *
* occasionally relicense the code to third parties as discussed above. *
* If you wish to specify special license conditions of your *
* contributions, just say so when you send them. *
* *
* This program is distributed in the hope that it will be useful, but *
* WITHOUT ANY WARRANTY; without even the implied warranty of *

*
* Fyodor - Wrote original
* William McVey - Added T:, U:, P: directives
* Doug Hoyte - Added [], name lookups, and wildcard expansion
*
* getpts() handles []
* Any port ranges included inside square brackets will have all
* their ports looked up in nmap-services or nmap-protocols
* and will only be included if they are found.
* Returns a scan_list* with all the ports that should be scanned.
*
* getpts() handles service/protocol name lookups and wildcard expansion.
* The service name can be specified instead of the port number.
* For example, "ssh" can be used instead of "22". You can use wildcards
* like "*" and "?". See the function wildtest() for the exact details.
* For example,
*
* nmap -p http* host
*
* Will scan http (80), http-mgmt (280), http-proxy (8080), https (443), etc.
*
* Matching is case INsensitive but the first character in a match MUST
* be lowercase so it doesn't conflict with the T:, U:, and P: directives.
*
* getpts() is unable to match service names that start with a digit
* like 3com-tsmux (106/udp). Use a pattern like "?com-*" instead.
*
* BE CAREFUL ABOUT SHELL EXPANSIONS!!!
* If you are trying to match the services nmsp (537/tcp) and nms (1429/tcp)
* and you execute the command
*
* ./nmap -p nm* host
*
* You will see
*
* Found no matches for the service mask 'nmap' and your specified protocols
* QUITTING!
*
* This is because nm* was expanded to the name of the binary file nmap in
* the current directory by your shell. When unsure, quote your port strings
* to be safe:
*
* ./nmap -p 'nm*' host
*
* getpts() is smart enough to keep the T: U: and P: directives nested
* and working in a logical manner. For instance,
*
* nmap -sTU -p [U:1025-],1-1024 host
*
* Will scan UDP ports 1025 and up that are found in the service file
* and all TCP/UDP ports below <= 1024. Notice that the U doesn't affect
* the outer part of the port expression. It's "closed".
