+ PARAMETERS
+
+ $ipfwpath = path to ipfw command
+ $rulenumber= ipfw rule number. one number for one client
+ $clientaddr= client machine's IP address
+ $userid = user's ID. Auth server ID is attached(usr@svr), if entered.
+ $macaddr = MAC address for the client machine
+ $interface = Network interface card name
+
+ CAUTIONS
+
+*Be care to execute quickly and without delay.
+ This script runs in EXCLUSIVE mode.
+
+*Be care to add least rule set.
+ The rules are added PER each client.
+
+*Be care to eliminate bug and security hole.
+ At modification, debug it perfectly in stand along mode.
+
+*If possible, the rule should be written in rc.firewall.
+ Following can be written in rc.firewall
+ Deny some protocol though authentication passed.
+ Allow to access some server without authentication.
+
+*Following might be written in this script.
+ Deny guest users to access internal network.
+ Deny a client having specific MAC address.
+ Forward some service to proxy server after authentication.
+ (Last one might be written in rc.firewall as the rule of other
+ side interface which is not used by opengate)
+
+ SIMPLE SCRIPT
+
+If you are confused, return to the following default script.

+ When a parameter is not found in <ExtraSet>, the default is used.
+
+ When userID is entered without extraID, ExtraId matchs to "default".
+ Thus if you want to find [user1] only in default server,
+ use as <ExtraSet ExtraId="default" UserIdPattern="^user1$">.
+
+ Example1 is used when user entered as [any_user@guest],
+ where "any_user" is any string.
+ It means that [xxx@guest] uses different auth server.
+
+ Example2 is used when [anyuser@admin].
+ It means that [xxx@adimin] can use many auth servers.
+
+ Example3 is used when [user1] or [user2].
+ It means that [user1] and [user2] emerge specific syslog(eg. mail).

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 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
+ 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) <year> <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., 59 Temple Place, Suite 330, Boston, MA 02111-1307 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) year 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.

+ <h1>ezXML - XML Parsing C Library</h1>
+ <h3>version 0.8.6</h3>
+ <p>
+ ezXML is a C library for parsing XML documents inspired by
+ <a href="http://www.php.net/SimpleXML">simpleXML</a> for
+ PHP. As the name implies, it's easy to use. It's ideal for parsing XML
+ configuration files or REST web service responses. It's also fast and
+ lightweight (less than 20k compiled). The latest version is available
+ here:
+ <a href="http://prdownloads.sf.net/ezxml/ezxml-0.8.6.tar.gz?download"
+ >ezxml-0.8.6.tar.gz</a>
+ </p>
+
+ <b>Example Usage</b>
+ <p>
+ Given the following example XML document:
+ </p>
+ <code>
+ <?xml version="1.0"?><br />
+ <formula1><br />
+ <team name="McLaren"><br />
+ <driver><br />
+ <name>Kimi
+ Raikkonen</name><br />
+ <points>112</points><br />
+ </driver><br />
+ <driver><br />
+ <name>Juan Pablo
+ Montoya</name><br />
+ <points>60</points><br />
+ </driver><br />
+ </team><br />
+ </formula1>
+ </code>
+ <p>
+ This code snippet prints out a list of drivers, which team they drive for,
+ and how many championship points they have:
+ </p>
+ <code>
+ ezxml_t f1 = ezxml_parse_file("formula1.xml"), team, driver;<br />
+ const char *teamname;<br />
+ <br />
+ for (team = ezxml_child(f1, "team"); team; team = team->next) {<br />
+ teamname = ezxml_attr(team, "name");<br />
+ for (driver = ezxml_child(team, "driver"); driver;
+ driver = driver->next) {<br />
+ printf("%s, %s: %s\n",
+ ezxml_child(driver, "name")->txt, teamname,<br />
+
+ ezxml_child(driver, "points")->txt);<br />
+ }<br />
+ }<br />
+ ezxml_free(f1);
+ </code>
+ <p>
+ Alternately, the following would print out the name of the second driver
+ on the first team:
+ </p>
+ <code>
+ ezxml_t f1 = ezxml_parse_file("formula1.xml");<br />
+ <br />
+ printf("%s\n", ezxml_get(f1, "team", 0, "driver", 1, "name", -1)->txt);
+ <br />ezxml_free(f1);
+ </code>
+ <p>
+ The -1 indicates the end of the argument list. That's pretty much all
+ there is to it. Complete API documentation can be found in ezxml.h.
+ </p>
+
+ <b>Known Limitations</b>
+ <ul>
+ <li>
+ ezXML is not a validating parser.
+ <br />
+ </li>
+ <li>
+ Loads the entire XML document into memory at once and does not allow for
+ documents to be passed in a chunk at a time. Large XML files can still
+ be handled though through <code>ezxml_parse_file()</code> and
+ <code>ezxml_parse_fd()</code>, which use mmap to map the file to a
+ virtual address space and rely on the virtual memory system to page in
+ data as needed.
+ <br />
+ </li>
+ <li>
+ Does not currently recognize all possible well-formedness errors. It
+ should correctly handle all well-formed XML documents and will either
+ ignore or halt XML processing on well-formedness errors. More
+ well-formedness checking will be added in subsiquent releases.
+ <br />
+ </li>
+ <li>
+ In making the character content of tags easy to access, there is no
+ way provided to keep track of the location of sub tags relative to the
+ character data. Example:
+ <p>
+ <code><doc>line one<br/><br />line two</doc></code>
+ </p>
+ <p>
+ The character content of the doc tag is reported as
+ <code>"line one\nline two"</code>, and <code><br/></code> is
+ reported as a sub tag, but the location of <code><br/></code>
+ within the character data is not. The function
+ <code>ezxml_toxml()</code> will convert an ezXML structure back to XML
+ with sub tag locations intact.
+ </p>
+ </li>
+ </ul>

+
+- ezXML is not a validating parser
+
+- Loads the entire XML document into memory at once and does not allow for
+ documents to be passed in a chunk at a time. Large XML files can still be
+ handled though through ezxml_parse_file() and ezxml_parse_fd(), which use mmap
+ to map the file to a virtual address space and rely on the virtual memory

+- Does not currently recognize all possible well-formedness errors. It should

+ XML processing on well-formedness errors. More well-formedness checking will
+ be added in subsiquent releases.
+
+- In making the character content of tags easy to access, there is no way
+ provided to keep track of the location of sub tags relative to the character
+ data. Example:
+
+ <doc>line one<br/>
+ line two</doc>
+
+ The character content of the doc tag is reported as "line one\nline two", and
+ <br/> is reported as a sub tag, but the location of <br/> within the
+ character data is not. The function ezxml_toxml() will convert an ezXML
+ structure back to XML with sub tag locations intact.

+How to use
+<ol>
+<li>Connect the target terminal to the access point of this page, and
+try network access to confirm that the network for the terminal is closed.
+<li>Load this page. If you already loaded, reload it.
+<li>The above is the list of addresses using this access point. The top of the list is the one detected most recently.
+<li>Choose an address in the list and push the "open" button. When a server replies, a timer starts.
+<li>Try to use the network at the target terminal.
+<li>If the network is not available, push "close" button and try other address.
+<li>If the network is available, push "close" button and confirm that the network is not available. Then push "register" button to jump to the registration page.
+</ol>
+</p>
+<p>
+Warning
+<ul>
+<li>When the timer does not start, contact an administrator, as the server might be malfunction.
+<li>The network is closed soon, even if you do not push the "close" button.
+However, it is desirable to close the network early with the "close" button.
+</ul>

+使用方法
+<ol>
+<li>登録を希望する端末で、この端末と同じアクセスポイントに接続して、ネッ
+トワークアクセスを試み、ネットワークが閉鎖していることを確認する。
+<li>このページを表示する。確認前に表示しているときはリロードを行う。
+<li>上記の表は、同一アクセスポイントを最近利用した端末のアドレス一覧である。リストの先頭が最も最近に検出した端末である。
+<li>登録希望端末と予想されるアドレスを選択して「開放」ボタンを押す。
+<li>サーバが応答して、ネットワークを開放すると、タイマーが始動する。
+<li>タイマー作動中に、登録希望端末でネットワークを利用してみる。
+<li>利用が不可であれば、「閉鎖」ボタンで閉鎖して、別のアドレスを試す。
+<li>利用が可能であれば、「閉鎖」ボタンで閉鎖して、利用が不可に戻ることを確認し、「登録」ボタンで登録ページへ移行する。
+</ol>
+</p>
+<p>
+注意事項
+<ul>
+<li>タイマーが始動しない場合はサーバ不調の可能性があるので、管理者に連絡すること。
+<li>「閉鎖」ボタンを押さなくてもネットワークは時間切れで閉鎖される。開放のままページ移行しても問題ない。しかし「閉鎖」ボタンで早期に閉鎖することが望ましい。

+
+ 1. Packet Check Cache
+ To speed up the packet check process, the address checked once
+ is ignored for a while.
+ The cache (key: MAC address) is used to decide
+ the necessity of checking.
+ The cache is maintained the information of arrived packets
+ by using hash-table and queue in the memory of local machine.
+ 2. Session Table
+ The table (key: MAC address) maintains temporal information
+ of terminals allowing the use of network now.
+ The data are stored in the DB of local machine.
+ 3. MAC address Table
+ The table (key: MAC address) maintains MAC addresses of terminals
+ and the owners' information.
+ The data are stored in the DB of a central machine
+ and accessed via network.
+ 4. Cache of MAC address Table
+ As the network DB access is time-consuming, the access cache
+ (key: MAC address) is maintained in the memory of local machine.
+
+MAC address is used as main key for the user terminal.
+IP address is kept only for information (firstly detected address only)

+ If address is included in table and time is new, skip checking.
+ Queue:
+ Address odrered by checked time.
+ If an old item is found in table, elder items are removed from table.
