+
+config CONFIG_IFUPDOWN
+	bool "ifupdown"
+	default n
+	help
+	  Activate or deactivate the specified interfaces.  This applet makes
+	  use of either "ifconfig" and "route" or the "ip" command to actually
+	  configure network interfaces.  Therefore, you will probably also want
+	  to enable either CONFIG_IFCONFIG and CONFIG_ROUTE, or enable
+	  CONFIG_FEATURE_IFUPDOWN_IP and the various CONFIG_IP options.  Of
+	  course you could use non-busybox versions of these programs, so
+	  against my better judgement (since this will surely result in plenty
+	  of support questions on the mailing list), I do not force you to
+	  enable these additional options.  It is up to you to supply either
+	  "ifconfig" and "route" or the "ip" command, either via busybox or via

+	  more secure alternative, you should seriously consider installing the
+	  very small Dropbear SSH daemon instead:
+		http://matt.ucc.asn.au/dropbear/dropbear.html
+
+	  Note that for busybox telnetd to work you need several things:
+	  First of all, your kernel needs:
+		  CONFIG_UNIX98_PTYS=y
+		  CONFIG_DEVPTS_FS=y
+
+	  Next, you need a /dev/pts directory on your root filesystem:
+
+		  $ ls -ld /dev/pts
+		  drwxr-xr-x  2 root root 0 Sep 23 13:21 /dev/pts/
+
+	  Next you need the pseudo terminal master multiplexer /dev/ptmx:
+
+		  $ ls -la /dev/ptmx
+		  crw-rw-rw-  1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
+
+	  Any /dev/ttyp[0-9]* files you may have can be removed.
+	  Next, you need to mount the devpts filesystem on /dev/pts using:
+
+		  mount -t devpts devpts /dev/pts
+
+	  You need to be sure that Busybox has CONFIG_LOGIN and
+	  CONFIG_FEATURE_SUID enabled.  And finally, you should make
+	  certain that Busybox has been installed setuid root:
+
+		chown root.root /bin/busybox
+		chmod 4755 /bin/busybox
+
+	  with all that done, telnetd _should_ work....
+
+
+config CONFIG_FEATURE_TELNETD_INETD

+	default n
+	depends on CONFIG_TFTP
+	help
+	  Enable debug settings for tftp.  This is useful if you're running
+	  into problems with tftp as the protocol doesn't help you much when
+	  you run into problems.
+
+config CONFIG_TRACEROUTE
+	bool "traceroute"
+	default n

+ *****************************************************************************
+ *
+ * Typical usage:
+ *   for non root user
+ * httpd -p 8080 -h $HOME/public_html
+ *   or for daemon start from rc script with uid=0:
+ * httpd -u www
+ * This is equivalent if www user have uid=80 to
+ * httpd -p 80 -u 80 -h /www -c /etc/httpd.conf -r "Web Server Authentication"
+ *
+ *
+ * When a url contains "cgi-bin" it is assumed to be a cgi script.  The
+ * server changes directory to the location of the script and executes it
+ * after setting QUERY_STRING and other environment variables.
+ *
+ * The server can also be invoked as a url arg decoder and html text encoder
+ * as follows:
+ *  foo=`httpd -d $foo`           # decode "Hello%20World" as "Hello World"
+ *  bar=`httpd -e "<Hello World>"`  # encode as "&#60Hello&#32World&#62"
+ * Note that url encoding for arguments is not the same as html encoding for
+ * presentation.  -d decodes a url-encoded argument while -e encodes in html
+ * for page display.
+ *
+ * httpd.conf has the following format:
+ *
+ * A:172.20.         # Allow address from 172.20.0.0/16
+ * A:10.0.0.0/25     # Allow any address from 10.0.0.0-10.0.0.127
+ * A:10.0.0.0/255.255.255.128  # Allow any address that previous set
+ * A:127.0.0.1       # Allow local loopback connections
+ * D:*               # Deny from other IP connections
+ * /cgi-bin:foo:bar  # Require user foo, pwd bar on urls starting with /cgi-bin/
+ * /adm:admin:setup  # Require user admin, pwd setup on urls starting with /adm/
+ * /adm:toor:PaSsWd  # or user toor, pwd PaSsWd on urls starting with /adm/
+ * .au:audio/basic   # additional mime type for audio.au files
+ *
+ * A/D may be as a/d or allow/deny - first char case insensitive
+ * Deny IP rules take precedence over allow rules.
+ *
+ *
+ * The Deny/Allow IP logic:
+ *
+ *  - Default is to allow all.  No addresses are denied unless
+ *         denied with a D: rule.
+ *  - Order of Deny/Allow rules is significant
+ *  - Deny rules take precedence over allow rules.
+ *  - If a deny all rule (D:*) is used it acts as a catch-all for unmatched
+ *       addresses.
+ *  - Specification of Allow all (A:*) is a no-op
+ *
+ * Example:
+ *   1. Allow only specified addresses
+ *     A:172.20          # Allow any address that begins with 172.20.
+ *     A:10.10.          # Allow any address that begins with 10.10.
+ *     A:127.0.0.1       # Allow local loopback connections
+ *     D:*               # Deny from other IP connections
+ *
+ *   2. Only deny specified addresses
+ *     D:1.2.3.        # deny from 1.2.3.0 - 1.2.3.255
+ *     D:2.3.4.        # deny from 2.3.4.0 - 2.3.4.255
+ *     A:*             # (optional line added for clarity)
+ *
+ * If a sub directory contains a config file it is parsed and merged with
+ * any existing settings as if it was appended to the original configuration.
+ *
+ * subdir paths are relative to the containing subdir and thus cannot
+ * affect the parent rules.
+ *
+ * Note that since the sub dir is parsed in the forked thread servicing the
+ * subdir http request, any merge is discarded when the process exits.  As a
+ * result, the subdir settings only have a lifetime of a single request.
+ *
+ *
+ * If -c is not set, an attempt will be made to open the default
+ * root configuration file.  If -c is set and the file is not found, the
+ * server exits with an error.

+ * Inetd - Internet super-server
+ *
+ * This program invokes all internet services as needed.
+ * connection-oriented services are invoked each time a
+ * connection is made, by creating a process.  This process
+ * is passed the connection as file descriptor 0 and is
+ * expected to do a getpeername to find out the source host
+ * and port.
+ *
+ * Datagram oriented services are invoked when a datagram
+ * arrives; a process is created and passed a pending message
+ * on file descriptor 0.  Datagram servers may either connect
+ * to their peer, freeing up the original socket for inetd
+ * to receive further messages on, or ``take over the socket'',
+ * processing all arriving datagrams and, eventually, timing
+ * out.  The first type of server is said to be ``multi-threaded'';
+ * the second type of server ``single-threaded''.
+ *
+ * Inetd uses a configuration file which is read at startup
+ * and, possibly, at some later time in response to a hangup signal.
+ * The configuration file is ``free format'' with fields given in the
+ * order shown below.  Continuation lines for an entry must being with
+ * a space or tab.  All fields must be present in each entry.
+ *
+ *      service name                    must be in /etc/services
+ *      socket type                     stream/dgram/raw/rdm/seqpacket

+ *   pseudo-terminal as stdin, stdout, and stderr. Telnetd manipulates the
+ *   master side of the pseudo-terminal, implementing the telnet protocol and
+ *   passing characters between the remote client and the login process.

+ * This program must be run by root or be setuid.  (I suggest that
+ * you *don't* make it setuid -- casual use could result in a lot
+ * of unnecessary traffic on our poor, congested nets.)
+ *
+ * I stole the idea for this program from Steve Deering.  Since
+ * the first release, I've learned that had I attended the right
+ * IETF working group meetings, I also could have stolen it from Guy
+ * Almes or Matt Mathis.  I don't know (or care) who came up with
+ * the idea first.  I envy the originators' perspicacity and I'm
+ * glad they didn't keep the idea a secret.
+ *
+ * Tim Seaver, Ken Adelman and C. Philip Wood provided bug fixes and/or
+ * enhancements to the original distribution.
+ *
+ * I've hacked up a round-trip-route version of this that works by
+ * sending a loose-source-routed udp datagram through the destination
+ * back to yourself.  Unfortunately, SO many gateways botch source
+ * routing, the thing is almost worthless.  Maybe one day...

+		    GNU GENERAL PUBLIC LICENSE
+		       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.
+
+		    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.)
+
+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.
+
+  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.
+
+  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
+
+	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.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+udhcp server/client package readme
+-------------------------
+
+The udhcp server/client package is primarily geared towards embedded
+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.

+-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
+	subnet		- The assigend subnet mask
+	timezone	- Offset in seconds from UTC
+	router		- A list of routers
+	timesvr		- A list of time servers
+	namesvr		- A list of IEN 116 name servers
+	dns		- A list of DNS server
+	logsvr		- A list of MIT-LCS UDP log servers
+	cookiesvr	- A list of RFC 865 cookie servers
+	lprsvr		- A list of LPR servers
+	hostname	- The assigned hostname
+	bootsize	- The length in 512 octect blocks of the bootfile
+	domain		- The domain name of the network
+	swapsvr		- The IP address of the client's swap server
+	rootpath	- The path name of the client's root disk
+	ipttl		- The TTL to use for this network
+	mtu		- The MTU to use for this network
+	broadcast	- The broadcast address for this network
+	ntpsrv		- A list of NTP servers
+	wins		- A list of WINS servers
+	lease		- The lease time, in seconds
+	dhcptype	- DHCP message type (safely ignored)
+	serverid	- The IP of the server
+	message		- Reason for a DHCPNAK
+	tftp		- The TFTP server name
+	bootfile	- The bootfile name
+
+additional options are easily added in options.c.
+
+
+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

+
+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:
+
+	LEASE_TIME: The default lease time if not specified in the config
+	file.
+
+	DHCPD_CONFIG_FILE: The defualt config file to use.

+TODO
+----
++ Check for valid IP, netmask, hostname, paths, strings, etc
++ Integrade README.*'s with manpages
++ using time(0) breaks if the system clock changes, find a portable solution
++ make failure of reading functions revert to previous value, not the default
++ sanity code for option[OPT_LEN]
++ fix aliasing (ie: eth0:0)
++ better standard linux distro support
++ make sure packet generation works on a wide varitey of arches
++ Interoperability testing
++ Hooks within the DHCP server
+	* Server notification when a lease is added/removed
++ Additional bootp support in client/server
++ Make serverid option in server configurable
++ Possibly add failure message to DHCP NAK
