+ngIRCd Release 17 (2010-11-07)
+
+  - doc: change path names in sample-ngircd.conf depending on sysconfdir
+  - Fix up generation and distribution of sample-ngircd.conf
+  - contrib/ngircd-redhat.init: updated email address of Naoya Nakazawa
+  - contrib/platformtest.sh: make command name quoting consistent
+
+  ngIRCd 17~rc3 (2010-10-27)
+  - Xcode builds: detect version number correctly, updateed project file
+    to use the Mac OS X 10.5.x SDK, disable pam_fail_delay() because it
+    is only available starting with Mac OS X 10.6, and generate a default
+    PAM configuration for the Mac OS X Installer.app package of ngIRCd.
+  - Debian: updated standards version to 3.9.1, added libpam0g-dev to the
+    dependencies, and install a default /etc/pam.d/ngircd allowing all logins.
+  - Make contrib/platformtest.sh more portable.
+  - Fix connect attempts to further IP addresses of outgoing server links.
+
+  ngIRCd 17~rc2 (2010-10-25)
+  - ZeroConf: include header files missing since commit a988bbc86a.
+  - Generate ngIRCd version number from GIT tag.
+  - Make sourcecode compatible with ansi2knr again. This allows to compile
+    ngIRCd using a pre-ANSI K&R C compiler again.
+  - ./configure: check if C compiler can compile ISO Standard C.
+  - ./configure: check support for C prototypes again.
+  - Don't use PARAMS() macro for function implementations.
+  - Added m68k/apple/aux3.0.1 (gcc 2.7.2) to doc/Platforms.txt.
+  - Only try to set FD_CLOEXEC if this flag is defined.
+  - Only use "__attribute__ ((unused))" if GCC >=2.8 is used.
+  - doc/Makefile.am: don't set docdir, automake handles it already.
+
+  ngIRCd 17~rc1 (2010-10-11)
+  - New configuration option "NoZeroConf" to disable service registration at
+    runtime even if ngIRCd is compiled with support for ZeroConf (e.g. using
+    Howl, Avahi or on Mac OS X).
+  - New configuration option "SyslogFacility" to define the syslog "facility"
+    (the "target"), to which ngIRCd should send its log messages.
+    Possible values are system dependant, but most probably "auth", "daemon",
+    "user" and "local1" through "local7" are possible values; see syslog(3).
+    Default is "local5" for historical reasons.
+  - Dump the "internal server state" (configured servers, established
+    connections and known clients) to the console or syslog when receiving
+    the SIGUSR2 signal and debug mode is enabled.
+  - Enable the daemon to disable and enable "debug mode" on runtime using
+    signal SIGUSR1, when debug code is compiled in, not only on startup
+    using the command line parameters.
+  - Signal handler: added new 'delayed' signal handlers, including fallback
+    to deprecated sysv API. And removed global NGIRCd_SignalRehash variable.
+  - IO: add io_cloexec() to set close-on-exec flag.
+  - ng_ipaddr.h: include required assert.h header.
+  - Conn_SyncServerStruct(): test all connections; and work case insensitive
+  - configure script: correctly indent IPv6 yes/no summary output.
+  - Don't reset My_Connections[Idx].lastping when reading data, so the
+    client lag debug-output is working again.
+  - Implement user mode "x": hostname cloaking (closes: #102).
+  - Make configure switch "--docdir" work (closes: #108).
+  - Reformat and update FAQ.txt a little bit.
+  - INSTALL: mention SSL, IPv6, and changed handling of MotdFile.
+  - Change MOTD file handling: ngIRCd now caches the contens of the MOTD
+    file, so the daemon now requires a HUP signal or REHASH command to
+    re-read the MOTD file when its content changed.
+  - Startup: open /dev/null before chroot'ing the daemon.
+  - Allow IRC ops to change channel modes even without OperServerMode set.
+  - Allow IRC operators to use MODE command on any channel (closes: #100).
+  - Added mailmap file for git-[short]log and git-blame.
+  - Authenticated users should be registered without the "~" mark.
+  - Set NoPAM=yes in configuration files used for the testsuite.
+  - New configuration option "NoPAM" to disable PAM.
+  - Implement asynchronous user authentication using PAM, please see the
+    file doc/PAM.txt for details.
+  - Resolver: Implement signal handler and catch TERM signals.
+  - Don't set a penalty time when doing DNS lookups.
+  - Add some documentation for using BOPM with ngIRCd, see doc/Bopm.txt.
+  - Implement user mode "c": receive connect/disconnect NOTICEs. Note that
+    this new mode requires the user to be an IRC operator.
+  - ngircd.init: require "$network" and "$remote_fs" when stopping ngircd.
+  - Show SSL status in WHOIS output, numeric 275.
+  - Include correct header files when testing for arpa/inet.h (Closes: #105).
+  - Don't access already freed memory in IRC_KILL().
+  - Fix "beeing" typo ...
+  - SSL/TLS: fix bogus "socket closed" error message.
+
+ngIRCd Release 16 (2010-05-02)
+
+  - doc/SSL: remove line continuation marker
+
+  ngIRCd 16~rc2 (2010-04-25)
+  - Updated some more copyright notices, it's 2010 already :-)
+  - Only compile in Get_Error() if really needed
+  - Fix gcc warning "ignoring return value of ..."
+  - Include netinet/in_systm.h alongside netinet/ip.h
+  - Include netinet/{in.h, in_systm.h} when checking for netinet/ip.h
+  - Only include <netinet/in_systm.h> if it exists
+  - Updated doc/Platforms.txt
+  - Enhace connection statistics counters: display total number of served
+    connections on daemon shutdown and when a new client connects using
+    the new numeric RPL_STATSCONN (250).
+
+  ngIRCd 16~rc1 (2010-03-25)
+  - Various fixes to the build system and code cleanups.
+  - contrib/platformtest.sh: Only show latest commit.
+  - Updatet doc/Platforms.txt, added new README-Interix.txt documenting
+    how to tun ngIRCd on Microsoft Services for UNIX (MS SFU, MS SUA).
+  - Updated links to the ngIRCd homepage (bug tracker, mailing list).
+  - Added missing modes to USERMODES #define
+  - Show our name (IRCD=ngIRCd) in ISUPPORT (005) numeric
+  - Quote received messages of ERROR commands in log output.
+  - ngircd.conf manual page: document missing "Password" variable.
+  - Implement WEBIRC command used by some Web-IRC frontends. The password
+    required to secure this command must be configured using the new
+    "WebircPassword" variable in the ngircd.conf file.
+  - Don't use port 6668 as example for both "Ports" and "SSLPorts".
+  - Remove limit on max number of configured irc operators.
+  - Only link "nsl" library when really needed.
+  - A new channel mode "secure connections only" (+z) has been implemented:
+    Only clients using a SSL encrypted connection to the server are allowed
+    to join such a channel.
+    But please note three things: a) already joined clients are not checked
+    when setting this mode, b) IRC operators are always allowed to join
+    every channel, and c) remote clients using a server not supporting this
+    mode are not checked either and therefore always allowed to join.
+
+ngIRCd Release 15 (2009-11-07)
+
+  - "ngircd --configtest": print SSL configuration options even when unset.
+
+  ngIRCd 15~rc1 (2009-10-15)
+  - Do not add default listening port (6667) if SSL ports were specified, so
+    ngIRCd can be configured to only accept SSL-encrypted connections now.
+  - Enable IRC operators to use the IRC command SQUIT (insted of the already
+    implemented but non-standard DISCONNECT command).
+  - New configuration option "AllowRemoteOper" (disabled by default) that
+    enables remote IRC operators to use the IRC commands SQUIT and CONNECT
+    on the local server.
+  - Mac OS X: fix test for packagemaker(1) tool in Makefile and use gcc 4.0
+    for Mac OS X 10.4 compatibility in the Xcode project file.
+  - Fix --with-{openssl|gnutls} to accept path names.
+  - Fix LSB header of Debian init script.
+  - Updated doc/Platforms.txt and include new script contrib/platformtest.sh
+    to ease generating platform reports.
+  - Fix connection information for already registered connections.
+  - Enforce upper limit on maximum number of handled commands. This implements
+    a throttling scheme: an IRC client can send up to 3 commands or 256 bytes
+    per second before a one second pause is enforced.
+  - Fix connection counter.
+  - Fix a few error handling glitches for SSL/TLS connections.
+  - Minor fixes to manual pages and documentation.
+
+ngIRCd Release 14.1 (2009-05-05)
+
+  - Security: fix remotely triggerable crash in SSL/TLS code.
+  - BSD start script contrib/ngircd.sh has been renamed to ngircd-bsd.sh.
+  - New start/stop script for RedHat-based distributions:
+    contrib/ngircd-redhat.init, thanks to Naoya Nakazawa <naoya@sanow.net>.
+  - Doxygen: update source code repository link to GIT.
+  - Debian: build ngircd-full-dbg package.
+  - Allow ping timeout quit messages to show the timeout value.
+  - Fix error handling on compressed links.
+  - Fix server list announcement.
+  - Do not remove hostnames from info text.
+
+ngIRCd Release 14 (2009-04-20)
+
+  - Display IPv6 addresses as "[<addr>]" when accepting connections.
+
+  ngIRCd 14~rc1 (2009-03-29)
+  - Updated Debian/Linux init script (see contrib/Debian/ngircd.init).
+  - Allow creation of persistent modeless channels.
+  - The INFO command reports the compile time now (if available).
+  - Spell check and enhance ngIRCd manual pages.
+  - Channel mode changes: break on syntax errors in MODE command.
+  - Support individual channel keys for pre-defined channels: introduce
+    new configuration variable "KeyFile" in [Channel] sections in ngircd.conf,
+    here a file can be configured for each pre-defined channel which contains
+    individual channel keys for different users.
+  - Remove limit on maximum number of predefined channels in ngircd.conf.
+  - Updated ngircd.spec file for building RPM packages.
+  - Add new and missing files to Mac OS X Xcode project, and update project.
+  - Reject masks with wildcard after last dot.
+  - TLS/SSL: remove useless error message when ssl connection is closed.
+  - Fix memory leak when a encrypted and compressed server link goes down.
+    (closes bug #95, reported by Christoph, fiesh@fiesh.homeip.net)
+  - Fix handling of channels containing dots.
+    (closes ug #93, reported by Gonosz Csiga)
+
+ngIRCd Release 13 (2008-12-25)
+
+  - Updated documentation, especially doc/Services.txt and doc/SSL.txt.
+  - Make the test suite work on OpenSolaris.
+
+  ngIRCd 13~rc1 (2008-11-21):
+  - New version number scheme :-)
+  - Initial support for IRC services, using a RFC1459 style interface,
+    tested with IRCServices (http://www.ircservices.za.net/) version 5.1.13.
+    For this to work, ngIRCd now supports server-server links conforming
+    to RFC 1459. New ngircd.conf(5) option: ServiceMask.
+  - Support for SSL-encrypted server-server and client-server links using
+    OpenSSL (configure: --with-openssl) or GNUTLS (configure: --with-gnutls).
+    New ngircd.conf(5) options: SSLPorts, SSLKeyFile, SSLKeyFilePassword,
+    SSLCertFile, SSLDHFile, and SSLConnect.
+  - Server local channels have been implemented, prefix "&", that are only
+    visible to users of the same server and are not visible in the network.
+    In addition ngIRCd creates a "special" channel &SERVER on startup and logs
+    all the messages to it that a user with mode +s receives.
+  - New make target "osxpkg" to build a Mac OS X installer package.
+  - Debug mode: enable support for GNU libc memory tracing (see mtrace(3)).
+  - SysV init script: use LSB logging functions, if available.
+  - Added some more FAQ entries (regarding logging and IRC operators).
+  - Allow IRC operators to overwrite channel limits.
+  - Support for enhanced PRIVMSG and NOTICE message targets.
+  - More tests have been added to the test-suite ("make check"), and two
+    servers are started for testing server-server linking.
+  - Added a timestamp to log messages to the console.
+  - New configuration option "NoIdent" to disable IDENT lookups even if the
+    daemon is compiled with IDENT support.

+ngIRCd Release 17 (2010-11-07)
+
+  - doc: change path names in sample-ngircd.conf depending on sysconfdir
+
+  ngIRCd 17~rc2 (2010-10-25)
+  - Generate ngIRCd version number from GIT tag.
+  - Make sourcecode compatible with ansi2knr again. This allows to compile
+    ngIRCd using a pre-ANSI K&R C compiler again.
+
+  ngIRCd 17~rc1 (2010-10-11)
+  - New configuration option "NoZeroConf" to disable service registration at
+    runtime even if ngIRCd is compiled with support for ZeroConf (e.g. using
+    Howl, Avahi or on Mac OS X).
+  - New configuration option "SyslogFacility" to define the syslog "facility"
+    (the "target"), to which ngIRCd should send its log messages.
+    Possible values are system dependant, but most probably "auth", "daemon",
+    "user" and "local1" through "local7" are possible values; see syslog(3).
+    Default is "local5" for historical reasons.
+  - Dump the "internal server state" (configured servers, established
+    connections and known clients) to the console or syslog when receiving
+    the SIGUSR2 signal and debug mode is enabled.
+  - Enable the daemon to disable and enable "debug mode" on runtime using
+    signal SIGUSR1, when debug code is compiled in, not only on startup
+    using the command line parameters.
+  - Implement user mode "x": hostname cloaking (closes: #102).
+  - Change MOTD file handling: ngIRCd now caches the contens of the MOTD
+    file, so the daemon now requires a HUP signal or REHASH command to
+    re-read the MOTD file when its content changed.
+  - Allow IRC ops to change channel modes even without OperServerMode set.
+  - Allow IRC operators to use MODE command on any channel (closes: #100).
+  - New configuration option "NoPAM" to disable PAM.
+  - Implement asynchronous user authentication using PAM, please see the
+    file doc/PAM.txt for details.
+  - Add some documentation for using BOPM with ngIRCd, see doc/Bopm.txt.
+  - Implement user mode "c": receive connect/disconnect NOTICEs. Note that
+    this new mode requires the user to be an IRC operator.
+  - Show SSL status in WHOIS output, numeric 275.
+
+ngIRCd Release 16 (2010-05-02)
+
+  ngIRCd 16~rc2 (2010-04-25)
+  - Enhace connection statistics counters: display total number of served
+    connections on daemon shutdown and when a new client connects using
+    the new numeric RPL_STATSCONN (250).
+
+  ngIRCd 16~rc1 (2010-03-25)
+  - Implement WEBIRC command used by some Web-IRC frontends. The password
+    required to secure this command must be configured using the new
+    "WebircPassword" variable in the ngircd.conf file.
+  - Remove limit on max number of configured irc operators.
+  - A new channel mode "secure connections only" (+z) has been implemented:
+    Only clients using a SSL encrypted connection to the server are allowed
+    to join such a channel.
+    But please note three things: a) already joined clients are not checked
+    when setting this mode, b) IRC operators are always allowed to join
+    every channel, and c) remote clients using a server not supporting this
+    mode are not checked either and therefore always allowed to join.
+
+ngIRCd Release 15 (2009-11-07)
+
+  ngIRCd 15~rc1 (2009-10-15)
+  - Do not add default listening port (6667) if SSL ports were specified, so
+    ngIRCd can be configured to only accept SSL-encrypted connections now.
+  - Enable IRC operators to use the IRC command SQUIT (insted of the already
+    implemented but non-standard DISCONNECT command).
+  - New configuration option "AllowRemoteOper" (disabled by default) that
+    enables remote IRC operators to use the IRC commands SQUIT and CONNECT
+    on the local server.
+  - Enforce upper limit on maximum number of handled commands. This implements
+    a throttling scheme: an IRC client can send up to 3 commands or 256 bytes
+    per second before a one second pause is enforced.
+
+ngIRCd Release 14.1 (2009-05-05)
+
+  - Security: fix remotely triggerable crash in SSL/TLS code.
+  - Debian: build ngircd-full-dbg package.
+  - Allow ping timeout quit messages to show the timeout value.
+
+ngIRCd Release 14 (2009-04-20)
+
+  ngIRCd 14~rc1 (2009-03-29)
+  - Allow creation of persistent modeless channels.
+  - The INFO command reports the compile time now (if available).
+  - Support individual channel keys for pre-defined channels: introduce
+    new configuration variable "KeyFile" in [Channel] sections in ngircd.conf,
+    here a file can be configured for each pre-defined channel which contains
+    individual channel keys for different users.
+  - Remove limit on maximum number of predefined channels in ngircd.conf.
+
+ngIRCd Release 13 (2008-12-25)
+
+  ngIRCd 13~rc1 (2008-11-21):
+  - New version number scheme :-)
+  - Initial support for IRC services, using a RFC1459 style interface,
+    tested with IRCServices (http://www.ircservices.za.net/) version 5.1.13.
+    For this to work, ngIRCd now supports server-server links conforming
+    to RFC 1459. New ngircd.conf(5) option: ServiceMask.
+  - Support for SSL-encrypted server-server and client-server links using
+    OpenSSL (configure: --with-openssl) or GNUTLS (configure: --with-gnutls).
+    New ngircd.conf(5) options: SSLPorts, SSLKeyFile, SSLKeyFilePassword,
+    SSLCertFile, SSLDHFile, and SSLConnect.
+  - Server local channels have been implemented, prefix "&", that are only
+    visible to users of the same server and are not visible in the network.
+    In addition ngIRCd creates a "special" channel &SERVER on startup and logs
+    all the messages to it that a user with mode +s receives.
+  - New make target "osxpkg" to build a Mac OS X installer package.
+  - New configuration option "NoIdent" to disable IDENT lookups even if the
+    daemon is compiled with IDENT support.
+
 ngIRCd 0.12.1 (2008-07-09)

+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.\

+\b0 \cf0 \
+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 1above, 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.)\
+\page \
+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.\
+\page \
+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.\

+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.\

+I. Introduction
+~~~~~~~~~~~~~~~~
+
+Citing <http://wiki.blitzed.org/BOPM>: "BOPM is an open source open proxy
+monitor, designed for use with hybrid-based ircds, although it can be used
+with slight modification on any server which has the ability to show connects
+to opers and that supports KLINEs."
+
+And starting with Release 17, ngIRCd supports all required log messages that
+BOPM requires to be useful.
+
+II. Installation
+~~~~~~~~~~~~~~~~~
+
+Install BOPM as usual, please see the BOPM documentation for details.
+Afterwards adjust the following configuration parameters that are important
+for ngIRCd:
+
+a) BOPM "IRC" section:
+
+  1) Set "server" and "port" accordingly,
+
+  2) adjust the "oper" line to match an [Operator] block in ngircd.conf,
+
+  3) change "mode" to "+ci" or "+c".
+
+  4) Set "connregex" to the following string, everything in one line(!):
+     "\\*\\*\\* Notice -- Client connecting: ([^ ]+) \\(([^@]+)@([^\\)]+)\\) \\[([0-9\\.]+)\\].*";
+     and comment all the other "connregex" examples (prepend a "#" character).
+
+  5) Set "kline" to "KILL %n :Open proxy found on your host!"; for example,
+     and comment all the other "kline" examples.
+
+b) BOPM "scanner" section:
+
+  Make sure you configure a valid "target_ip" and "target_port" for the
+  configured scanners to test. And please note that you CAN'T USE the port
+  of ngIRCd, because ngIRCd doesn't send any banner message by default!
+
+  So you need a service what sends a banner, so for example POP3, SMTP,
+  IMAP, or SSH daemons should work ...

+
+
+I. Introduction
+~~~~~~~~~~~~~~~
+
+Creating a new ngIRCd release requires a few steps to follow: the source
+tree must be in a releasable state (be up to date, include all required
+patches, be tested on as many platforms as possible), a name for the new
+release must be chosen, and all the files describing the release must be
+updated accordingly.
+
+Since ngIRCd release 13 (2009-12-25) we use "simple" release numbers for
+major releases (e.g. "13", "17", "42", ...) introducing new features and
+sub-releases for bug fixes only (e.g. "14.1", "22.3", ...).
+
+When creating pre-releases or release candidates, please use the tilde ("~")
+character to separate the "postfix" in the release number (e.g. "17~rc2"
+or "123.4~rc6").
+
+The release/version number of a build is automatically generated using the
+GIT "describe" command, see git-describe(1). Therefore it is required that
+a new release is tagged in the GIT tree and that the configure script is
+up-to-date (e.g. using ./autogen.sh) before generating the archives!
+
+
+II. How to prepare a new ngIRCd release?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+a) Make sure the source tree is in a releasable state ;-)
+
+b) Make sure you have working versions of GNU autoconf and GNU automake
+   installed on the system you use for generating the release:
+   as of October 2010 we are using GNU autoconf 2.61 and GNU automake 1.10.1
+   which seem to work just fine.
+
+c) Update the files describing the new release:
+    - ChangeLog
+    - NEWS
+
+d) Update the version numbers in the following files:
+    - contrib/ngircd.spec
+
+e) Generate a new Debian change log entry in the following file, e.g. using
+   the Debian "dch" tool of the "devscripts" package:
+    - contrib/Debian/changelog
+
+f) Commit the above changes to GIT: "git add", "git commit"
+
+g) Create a new signed GIT tag for the new release: "git tag -s".
+   Please note that we don't use the tilde ("~") here, instead use a simple
+   hyphen ("-") as delimiter: e.g. "rel-16" "rel-17-rc1", "rel-18-pre2", ...
+
+h) Run "./autogen.sh" to update the ./configure script with the correct
+   release number (autogenerated using "git describe", see above).
+
+i) Run "./configure" to rebuild all generated Makefiles.
+
+j) Run "make distcheck" to generate the distribution archives.
+
+k) Sign the distribution archive(s) using GnuPG: "gpg -b <archivefile>"
+
+l) Upload and distribute the newly generated ngIRCd release archive(s)
+   and GnuPG signatures.
+
+m) Write an announcement to the mailing list, freshmeat, Twitter, ...
+
+n) Relax :-)

+A very simple -- and quite useless ;-) -- example would be:
+
+	/etc/pam.d/ngircd:
+	  auth  required  pam_debug.so
+
+Here the "pam_debug" module will be called each time a client connects to
+the ngIRCd and has sent its PASS, NICK, and USER commands.
+
+Please note ONE VERY IMPORTANT THING:
+
+All the PAM modules are executed with the privileges of the user ngIRCd
+is running as. Therefore a lot of PAM modules aren't working as expected,
+because they need root privileges ("pam_unix", for example)!
+Only PAM modules not(!) requiring root privileges (such as "pam_pgsql",
+"pam_mysql", "pam_opendirectory" ...) can be used in conjunction with ngIRCd.

-ngIRCd actually doesn't support secure connections for client-server or
-server-server links using SSL, the Secure Socket Layer, by itself. But you can
-use the stunnel(8) command to make this work.
+ngIRCd supports SSL/TLSv1 encrypted connections using the OpenSSL or GnuTLS
+libraries. Both encrypted server-server links as well as client-server links
+are supported.
+
+SSL is a compile-time option which is disabled by default. Use one of these
+options of the ./configure script to enable it:
+
+  --with-openssl     enable SSL support using OpenSSL
+  --with-gnutls      enable SSL support using GnuTLS
+
+You also need a key/certificate, see below for how to create a self-signed one.
+
+From a feature point of view, ngIRCds support for both libraries is
+comparable. The only major difference (at this time) is that ngircd with gnutls
+does not support password protected private keys.
+
+Configuration
+~~~~~~~~~~~~~
+
+To enable SSL connections a separate port must be configured: it is NOT
+possible to handle unencrypted and encrypted connections on the same port!
+This is a limitation of the IRC protocol ...
+
+You have to set (at least) the following configuration variables in the
+[GLOBAL] section of ngircd.conf(5): SSLPorts, SSLKeyFile, and SSLCertFile.
+
+Now IRC clients are able to connect using SSL on the configured port(s).
+(Using port 6697 for encrypted connections is common.)
+
+To enable encrypted server-server links, you have to additionally set
+SSLConnect to "yes" in the corresponding [SERVER] section.
+
+
+Creating a self-signed certificate
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+OpenSSL:
+
+Creating a self-signed certificate and key:
+ $ openssl req -newkey rsa:2048 -x509 -keyout server-key.pem -out server-cert.pem -days 1461
+Create DH parameters (optional):
+ $ openssl dhparam -2 -out dhparams.pem 2048
+
+GnuTLS:
+
+Creating a self-signed certificate and key:
+ $ certtool --generate-privkey --bits 2048 --outfile server-key.pem
+ $ certtool --generate-self-signed --load-privkey server-key.pem --outfile server-cert.pem
+Create DH parameters (optional):
+ $ certtool  --generate-dh-params --bits 2048 --outfile dhparams.pem
+
+
+Alternate approach using stunnel(1)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Alternatively (or if you are using ngIRCd compiled without support
+for GnuTLS/OpenSSL), you can use external programs/tools like stunnel(1) to
+get SSL encrypted connections:

+
+At the moment, ngIRCd doesn't implement a "special IRC services interface".
+But services acting as a "regular server" are supported, either using the IRC
+protocol defined in RFC 1459 or RFC 2812.
+
+Services have been tested using "IRC Services" version 5.x by Andrew Church,
+homepage: <http://www.ircservices.za.net/>. This document describes setting up
+ngIRCd and these services.
+
+
+Setting up ngIRCd
+~~~~~~~~~~~~~~~~~
+
+The "pseudo server" handling the IRC services is configured as a regular
+remote server in the ngircd.conf(5). In addition the variable "ServiceMask"
+should be set, enabling this ngIRCd to recognize the "pseudo users" as IRC
+services instead of regular IRC users.
+
+Example:
+
+  [SERVER]
+     Name = services.irc.net
+     MyPassword = 123abc
+     PeerPassword = 123abc
+     ServiceMask = *Serv
+
+
+Setting up IRC Services 5.1.x
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+IRC Services 5.1.3 and above can be used with ngIRCd using the "rfc1459"
+protocol module.
+
+Please note that versions up to and including 5.1.3 contain a bug that
+sometimes causes IRC Services to hang on startup. There are two workarounds:
+ a) send the services process a HUP signal ("killall -HUP ircservices")
+ b) apply this patch to the IRC Services source tree:
+    <ftp://ngircd.barton.de/ngircd/contrib/IRCServices513-FlushBuffer.patch>
+
+At least the following settings have to be tweaked, in addition to all the
+settings marked as required by IRC Services:
+
+In ircservices.conf:
+
+  Variable		Example value
+
+  RemoteServer		server.irc.net 6667 "123abc"
+  ServerName		"services.irc.net"
+  LoadModule		protocol/rfc1459
+
+In modules.conf:
+
+  Module		protocol/rfc1459
+
+The documentation of IRC Services can be found here:
+<http://www.ircservices.za.net/docs/>
+
+Please let us know if you are successfully using other IRC service packages or
+which problems you encounter, thanks!
