-                      Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-                          675 Mass Ave, Cambridge, MA 02139, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                           Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-\f
-                   GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-\f
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-\f
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-\f
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-                           NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-                    END OF TERMS AND CONDITIONS
-\f
-       Appendix: How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) 19yy  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) 19yy name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-

-systems. It does however, strive to be fully functional, and RFC
-compliant.
-
-
-compile time options
--------------------
-
-The Makefile contains three of the compile time options:
-
-       UDHCP_DEBUG: If UDHCP_DEBUG is defined, udhcpd will output extra
-       debugging output, compile with -g, and not fork to the background when
-       run.
-       UDHCP_SYSLOG: If UDHCP_SYSLOG is defined, udhcpd will log all its
-       messages syslog, otherwise, it will attempt to log them to stdout.
-
-       COMBINED_BINARY: If COMBINED_BINARY is define, one binary, udhcpd,
-       is created. If called as udhcpd, the dhcp server will be started.
-       If called as udhcpc, the dhcp client will be started.
-
-dhcpd.h contains the other three compile time options:
-
-       LEASE_TIME: The default lease time if not specified in the config
-       file.
-
-       LEASES_FILE: The default file for storing leases.
-
-       DHCPD_CONFIG_FILE: The defualt config file to use.
-
-options.c contains a set of dhcp options for the client:
-
-       name[10]: The name of the option as it will appear in scripts
-
-       flags: The type of option, as well as if it will be requested
-       by the client (OPTION_REQ)
-
-       code: The DHCP code for this option
-
-
-busybox drop-in
---------------
-udhcp is now a drop-in component for busybox (http://busybox.net).
-To update busybox to the latest revision, simply do a:
-
-cp *.[ch] README AUTHORS COPYING ChangeLog TODO \
-       <busybox_source>/networking/udhcp
-
-The only two files udhcp does not provide are config.in and
-Makefile.in, so these may need to be updated from time to time.

-udhcp lease dump (dumpleases)
-----------------------------
-
-dumpleases displays the leases written out by the udhcpd server. Lease
-times are stored in the file by time remaining in lease (for systems
-without clock that works when there is no power), or by the absolute
-time that it expires in seconds from epoch. dumpleases accepts the

--a, --absolute         Interpret lease times as expiration time.
--r, --remaining                Interpret lease times as remaining time.
--f, --file=FILE                Read lease information from FILE.
--h, --help             Display help.

-udhcp client (udhcpc)
---------------------
-
-The udhcp client negotiates a lease with the DHCP server and notifies
-a set of scripts when a leases is obtained or lost.
-
-
-command line options
--------------------
-
-The command line options for the udhcp client are:
-
--c, --clientid=CLIENTID         Set client identifier.  Type is first char.
--C, --clientid-none             Suppress default client identifier
--V, --vendorclass=CLASSID       Set vendor class identifier
--H, --hostname=HOSTNAME         Client hostname
--h,                             Alias for -H
--F, --fqdn=FQDN                 Client fully qualified domain name
--f, --foreground                Do not fork after getting lease
--b, --background                Fork to background if lease cannot be
-                                immediately negotiated.
--i, --interface=INTERFACE       Interface to use (default: eth0)
--n, --now                       Exit with failure if lease cannot be
-                                immediately negotiated.
--p, --pidfile=file              Store process ID of daemon in file
--q, --quit                      Quit after obtaining lease
--r, --request=IP                IP address to request (default: none)
--s, --script=file               Run file at dhcp events (default:
-                                /usr/share/udhcpc/default.script)
--v, --version                   Display version
-
-
-If the requested IP address cannot be obtained, the client accepts the
-address that the server offers.
-
-
-udhcp client scripts
--------------------
-
-When an event occurs, udhcpc calls the action script. udhcpc never does
-any configuration of the network interface itself, but instead relies on
-a set of scripts. The script by default is
-/usr/share/udhcpc/default.script but this can be changed via the command
-line arguments. The three possible arguments to the script are:
-
-       deconfig: This argument is used when udhcpc starts, and
-       when a leases is lost. The script must put the interface in an
-       up, but deconfigured state, ie: ifconfig $interface 0.0.0.0.
-
-       bound: This argument is used when udhcpc moves from an
-       unbound, to a bound state. All of the paramaters are set in
-       enviromental variables, The script should configure the interface,
-       and set any other relavent parameters (default gateway, dns server,
-       etc).
-
-       renew: This argument is used when a DHCP lease is renewed. All of
-       the paramaters are set in enviromental variables. This argument is
-       used when the interface is already configured, so the IP address,
-       will not change, however, the other DHCP paramaters, such as the
-       default gateway, subnet mask, and dns server may change.
-
-       nak: This argument is used with udhcpc receives a NAK message.
-       The script with the deconfig argument will be called directly
-       afterwards, so no changes to the network interface are neccessary.
-       This hook is provided for purely informational purposes (the
-       message option may contain a reason for the NAK).
-
-The paramaters for enviromental variables are as follows:
-
-       $HOME           - The set $HOME env or "/"
-       $PATH           - the set $PATH env or "/bin:/usr/bin:/sbin:/usr/sbin"
-       $1              - What action the script should perform
-       interface       - The interface this was obtained on
-       ip              - The obtained IP
-       mask            - The number of bits in the netmask (ie: 24)
-       siaddr          - The bootp next server option
-       sname           - The bootp server name option
-       boot_file       - The bootp boot file option

-note on udhcpc's random seed
----------------------------
-
-udhcpc will seed its random number generator (used for generating xid's)
-by reading /dev/urandom. If you have a lot of embedded systems on the same
-network, with no entropy, you can either seed /dev/urandom by a method of
-your own, or doing the following on startup:
-
-ifconfig eth0 > /dev/urandom
-
-in order to seed /dev/urandom with some data (mac address) unique to your
-system. If reading /dev/urandom fails, udhcpc will fall back to its old
-behavior of seeding with time(0).
-
-
-signals accepted by udhcpc
--------------------------
-
-udhcpc also responds to SIGUSR1 and SIGUSR2. SIGUSR1 will force a renew state,
-and SIGUSR2 will force a release of the current lease, and cause udhcpc to
-go into an inactive state (until it is killed, or receives a SIGUSR1). You do
-not need to sleep between sending signals, as signals received are processed
-sequencially in the order they are received.
-
-
-compile time options
--------------------
-
-options.c contains a set of dhcp options for the client:
-
-       name[10]: The name of the option as it will appear in scripts
-
-       flags: The type of option, as well as if it will be requested
-       by the client (OPTION_REQ)
-
-       code: The DHCP code for this option

-udhcp server (udhcpd)
---------------------
-
-The only command line argument to udhcpd is an optional specifed
-config file. If no config file is specified, udhcpd uses the default
-config file, /etc/udhcpd.conf. Ex:
-
-udhcpd /etc/udhcpd.eth1.conf
-
-The udhcp server employs a number of simple config files:
-
-udhcpd.leases
-------------
-
-The udhcpd.leases behavior is designed for an embedded system. The
-file is written either every auto_time seconds, or when a SIGUSR1
-is received (the auto_time timer restarts if a SIGUSR1 is received).
-If you send a SIGTERM to udhcpd directly after a SIGUSR1, udhcpd will
-finish writing the leases file and wait for the aftermentioned script
-to be executed and finish before quiting, so you do not need to sleep
-between sending signals. When the file is written, a script can be
-optionally called to commit the file to flash. Lease times are stored
-in the file by time remaining in lease (for systems without clock
-that works when there is no power), or by the absolute time that it
-expires in seconds from epoch. In the remaining format, expired leases
-are stored as zero. The file is of the format:
-
-16 byte MAC
-4 byte ip address
-u32 expire time
-16 byte MAC
-4 byte ip address
-u32 expire time
-.
-etc.
-
-example: hexdump udhcpd.leases
-
-0000000 1000 c95a 27d9 0000 0000 0000 0000 0000

-0000020 0000 0000 0000 0000 a8c0 140a 0d00 4e29
-0000030
-
-
-udhcpd.conf
-----------
-
-The format is fairly simple, there is a sample file with all the
-available options and comments describing them in samples/udhcpd.conf
-
-compile time options
--------------------
-
-dhcpd.h contains the other two compile time options:
