ngIRCd Release 21~rc1

Kill all clients that match a new GLINE/KLINE mask and genrate apropriate
KILL commands. These KILL commands can be superfluous, but are required
when the IRC Operator isn't allowd to set remote G-Lines or if there are
older servers in the network that don't kill clients on GLINE/KLINE.

Closes bug #156.

+ngIRCd 21~rc1 (2013-10-05)
+
+  - Actually KILL clients on GLINE/KLINE. (Closes bug #156)
+  - Adjust log messages for invalid and spoofed prefixes, which cleans up
+    logging of commands related to already KILL'ed clients. And don't
+    forward KILL commands for (already) unknown clients any more to prevent
+    unnecessary duplicates.
+  - Add support to show all user links using the "STATS L" (uppercase)
+    command (restricted to IRC Operators).
+  - Fixed blocking of server reconnects in some error confitions.
+  - Don't ignore SSL-related errors during startup any more: abort startup
+    when SSL is requested by the configuration but can't be initialized and
+    don't continue only listening on plain text communicaiton ports.
+    (Closes bug #163)
+  - Implement configurable SSL cipher list selection for GnuTLS and OpenSSL
+    using the new configuration option "CipherList". In addition, this
+    changes the defaults to more secure values: "HIGH:!aNULL:@STRENGTH" for
+    OpenSSL, and "SECURE128" for GnuTLS.
+  - Fix "TRACE": Correctly return ERR_NEEDMOREPARAMS(461) (which basically
+    is "syntax error") when there are too many parameters.
+  - Clean up lots of permission and parameter checks in functions handling
+    IRC commands; and more consistently add penalty times on errors.
+  - Fix error numeric of WHOIS when no nick namename has been provided:
+    as per RFC it shoud be ERR_NONICKNAMEGIVEN(431).
+  - Only log "IDENT ... no result" messages when an IDENT looked took place
+    and didn't return any data, not when IDENT has been disabled.
+  - Show connection flag "s" (SSL) in RPL_TRACE{LINK|SERVER} messages: now
+    you can check if a server-to-server link is SSL-encrypted or not using
+    the IRC "TRACE" command.
+  - Correctly discard supplementary groups on server startup.
+  - Save client IP address text for "WebIRC" users and correctly display
+    it on WHOIS, for example. (Closes bug #159)
+  - Implement the new configuration option "DefaultUserModes" which lists
+    user modes that become automatically set on new local clients right
+    after login. Please note that only modes can be set that the client
+    could set on itself, so you can't set "a" (away) or "o" (IRC Op),
+    for example! User modes "i" (invisible) or "x" (cloaked) etc. are
+    "interesting", though. (Closes bug #160)
+  - Add support for the new METADATA "account" property, which allows
+    services to automatically identify users after netsplits and across
+    service restarts.
+  - Enforce "penalty times" on error conditions more consistently and in
+    more places. Now most error codes sent back from the IRC server to the
+    client should result in a 2 second "penalty".
+  - Implement a new configuration option "AllowedChannelTypes" that lists
+    all allowed channel types (channel prefixes) for newly created channels
+    on the local server. By default, all supported channel types are allowed.
+    If set to the empty string, local clients can't create new channels at
+    all, which equals the old "PredefChannelsOnly = yes" setting.
+    This change deprecates the "PredefChannelsOnly" variable, too, but it is
+    still supported and translated to the apropriate "AllowedChannelTypes"
+    setting. When the old "PredefChannelsOnly" variable is processed, a
+    warning message is logged. (Closes bug #152)
+  - Add support for "client certificate fingerprinting". When a client
+    passes an SSL certificate to the server, the "fingerprint" will be
+    forwarded in the network which enables IRC services to identify the
+    user using this certificate and not using passwords.
+  - IRC Operator names, as defined in ngircd.conf, are logged now when
+    handling successful OPER commands.
+  - Some error conditions while handling IRC commands, like "permission
+    denied" or "need more parameters", result in more penalty times.
+  - The numeric replies of some commands became split too early which
+    resulted in more numeric reply lines than necessary.
+  - Implement a new configuration option "IncludeDir" in the "[Options]"
+    section that can be used to specify a directory which can contain
+    further configuration files and configuration file snippets matching
+    the pattern "*.conf". These files are read in after the main server
+    configuration file ("ngircd.conf" by default) has been read in and
+    parsed.  The default is "$SYSCONFDIR/ngircd.conf.d", so that it is
+    possible to adjust the configuration only by placing additional files
+    into this directory. (Closes bug #157)
+  - Fix use-after-free in the Lists_CheckReason() function, which is used
+    to check if a client is a member of a particular ban/invite/... list.
+  - Xcode: fix detection of host OS, vendor, and CPU type, and update
+    project settings for Xcode 5.
+  - OS X PackageMaker: use relative path names in project files and package
+    with correct file permissions (requires root privileges on "make").
+  - Add Travis-CI configuration file (".travis.yml") to project.
+  - Look for possible cloaked Masks in Lists. Users with +x usermode can
+    be banned with their cloaked hostname now.
+  - Don't read SSL client data before DNS resolver is finished which could
+    have resulted in discarding the resolved client hostname and IDENT
+    reply afterwards, because in some situations (timing dependent) the
+    NICK and USER commands could have already been read in from the client,
+    stored in the buffer, and been processed.
+    Thanks to Julian Brost for reporting the issue and testing, and to
+    Federico G. Schwindt <fgsch@lodoss.net> for helping to debug it!
+  - Increase password length limit to 64 characters. (Closes bug #154)
+  - doc/Services.txt: Update Anope status and URL.
+  - Clean up Xcode project file, remove outdated files, add missing ones.
+  - Update Doxygen configuration file.
+  - configure: search for iconv_open as well as libiconv_open, because
+    on some installations iconv_open() is actually libiconv_open().
+    iconv_open() is the glibc version while libiconv_open() is the
+    libiconv version, now both variants are supported. (Closes bug #151)
+  - ngIRCd now accepts user names including "@" characters, saves the
+    unmodified name for authentication but stores only the part in front
+    of the "@" character as "IRC user name". And the latter is how
+    ircd2.11, Bahamut, and irc-seven behave as well. (Closes bug #155)
+  - Lots of IRC "information functions" like ADMIN, INFO, ... now accept
+    server masks and names of connected users (in addition to server names)
+    for specifying the target server of the command. (Closes bug #153)
+  - Implement a new configuration option "IdleTimeout" in the "[Limits]"
+    section of the configuration file which can be used to set a timeout
+    in seconds after which the whole daemon will shutdown when no more
+    connections are left active after handling at least one client.
+    The default is 0, "never".
+    This can be useful for testing or when ngIRCd is started using "socket
+    activation" with systemd(8), for example.
+  - Implement support for systemd(8) "socket activation".
+  - contrib/README: add description for more files.
+  - Enable WHOIS to display information about IRC Services using the new
+    numeric 310(RPL_WHOISSERVICE) This numeric is used for this purpose by
+    InspIRCd, for example -- but as usual, other numerics are in use, too,
+    like 613 in UltimateIRCd ...
+    Please note that neither the Operator (+o) not the "bot status" (+B)
+    of an IRC service id displayed in the output.
+  - Exit message: use singular & plural :-)
+  - autogen.sh: Check for autoconf/automake wrapper scripts
+  - Add missing punctuation marks in log messages, adjust some severity
+    levels, and make SSL-related messages more readable.
+  - AUTHORS file: Update list of contributors.
+  - Update systemd(8) example configuration files in ./contrib/ directory:
+    the "ngircd.service" file now uses the "forking" service type which
+    enhances the log messages shown by "systemctl status ngircd.service",
+    and the new "ngircd.socket" file configures a systemd socket that
+    configures a socket for ngIRCd and launches the daemon on demand.
+  - Enhance help system and the HELP command: now a "help text file" can be
+    set using the new configuration option "HelpFile" ("global" section),
+    which is read in and parsed on server startup and configuration reload,
+    and then is used to output individual help texts to specific topics.
+    Please see the file ./doc/Commands.txt for details.
+
+ngIRCd 20.3 (2013-08-23)
+
+  - Security: Fix a denial of service bug (server crash) which could happen
+    when the configuration option "NoticeAuth" is enabled (which is NOT the
+    default) and ngIRCd failed to send the "notice auth" messages to new
+    clients connecting to the server (CVE-2013-5580).
+
+ngIRCd 20.2 (2013-02-15)
+
+  - Security: Fix a denial of service bug in the function handling KICK
+    commands that could be used by arbitrary users to to crash the daemon
+    (CVE-2013-1747).
+  - WHO command: Use the currently "displayed hostname" (which can be cloaked!)
+    for hostname matching, not the real one. In other words: don't display all
+    the cloaked users on a specific real hostname!
+  - configure: The header file "netinet/in_systm.h" already is optional in
+    ngIRCd, so don't require it in the configure script. Now ngIRCd can be
+    built on Minix 3 again :-)
+  - Return better "Connection not registered as server link" errors: Now ngIRCd
+    returns a more specific error message for numeric ERR_NOTREGISTERED(451)
+    when a regular user tries to use a command that isn't allowed for users but
+    for servers.
+  - Don't report ERR_NEEDMOREPARAMS(461) when a MDOE command with more modes
+    than nicknames is handled, as well as for channel limit and key changes
+    without specifying the limit or key parameters.
+    This is how a lot (all?) other IRC servers behave, including ircd2.11,
+    InspIRCd, and ircd-seven. And because of clients (tested with Textual and
+    mIRC) sending bogus MODE commands like "MODE -ooo nick", end-users got the
+    expected result as well as correct but misleading error messages ...
+  - Correctly detect when SSL subsystem must be initialized and take
+    outgoing connections (server links!) into account, too.
+  - autogen.sh: Enforce serial test harness on GNU automake >=1.13. The
+    new parallel test harness which is enabled by default starting with
+    automake 1.13 isn't compatible with our test suite.
+    And don't use "egrep -o", instead use "sed", because it isn't portable
+    and not available on OpenBSD, for example.
+
+ngIRCd 20.1 (2013-01-02)
+
+  - Allow ERROR command on server and service links only, ignore them and
+    add a penalty time on all other link types.
+  - Enforced mode setting by IRC Operators: Only check the channel user
+    modes of the initiator if he is joined to the channel and not an IRC
+    operator enforcing modes (which requires the configuration option
+    "OperCanUseMode" to be enabled), because trying to check channel user
+    modes of a non-member results in an assertion when running with debug
+    code or could crash the daemon otherwise. This closes bug #147, thanks
+    to James Kirwill <james.kirwill@bk.ru> for tracking this down!
+  - Fix build system to cope with spaces in path names.
+  - Code cleanups, mostly to fix build warnings on Cygwin.
+
+ngIRCd 20 (2012-12-17)
+
+  - Allow user names ("INDENT") up to 20 characters when ngIRCd has not
+    been configured for "strict RFC mode". This is useful if you are using
+    external (PAM) authentication mechanisms that require longer user names.
+    Patch suggested by Brett Smith <brett@w3.org>, see
+    <http://arthur.barton.de/pipermail/ngircd-ml/2012-October/000579.html>.
+
+  ngIRCd 20~rc2 (2012-12-02)
+  - Rework cloaked hostname handling and implement the "METADATA cloakhost"
+    subcommand: Now ngIRCd uses two fields internally, one to store the
+    "real" hostname and one to save the "cloaked" hostname. This allows
+    "foreign servers" (aka "IRC services") to alter the real and cloaked
+    hostnames of clients without problems, even when the user itself issues
+    additional "MODE +x" and "MODE -x" commands.
+  - RPL_UMODEIS: send correct target name, even on server links.
+  - Update platformtest.sh to follow autoconf changes and only generate
+    the "configure" script when it is missing.
+  - Fix the test suite to correctly execute test scripts even when stdout
+    is redirected.
+  - Fix some compiler warnings on NetBSD and OpenBSD.
+
+  ngIRCd 20~rc1 (2012-11-11)
+  - Update doc/Services.txt: describe the upcoming version of Anope 1.9.8,
+    then including a protocol module for ngIRCd. And remove our own patches
+    in ./contrib/Anope because they aren't supported any more ...
+  - Implement new "METADATA" command which can be used by remote servers
+    and IRC services to update client metadata like the client info text
+    ("real name"), user name, and hostname, and use this command to
+    configure an cloaked hostname (user mode "+x") on remote servers:
+    This prevents "double cloaking" of hostnames and even cloaked
+    hostnames are in sync on all servers supporting "METADATA" now.
+  - Fix error message when trying to join non-predefined channels and the
+    "PredefChannelsOnly" configuration option is set.
+  - Implement new IRC "SVSNICK" command to allow remote servers (and IRC
+    services) to change nicknames of already registered users. The SVSNICK
+    command itself doesn't change the nickname, but it becomes forwarded
+    to the server to which the user is connected to. And then this server
+    initiates the real nickname changing using regular NICK commands.
+    This allows to run mixed networks with old servers not supporting the
+    SVSNICK command, because SVSNICK commands for nicknames on such servers
+    are silently ignored and don't cause a desynchronization of the network.
+  - Make server reconnect time a little bit more random, so that two
+    servers trying to connect to each other asynchronously don't try this
+    in exactly the same time periods and kick each other off ...
+  - Don't accept connections for servers already being linked: there was a
+    time frame that could result in one connection overwriting the other,
+    e. g. the incoming connection overwriting the status of the outgoing
+    one. And this could lead to all kind of weirdness (even crashes!) later
+    on: now such incoming connections are dropped.
+  - New configuration option "MaxListSize" to configure the maximum number
+    of channels returned by a LIST command. The default is 100, as before.
+  - Implement user mode "b", "block messages": when a user has set mode "b",
+    all private messages and notices to this user are blocked if they don't
+    originate from a registered user, an IRC Op, server or service. The
+    originator gets an error numeric sent back in this case,
+    ERR_NONONREG_MSG (486), which is used by UnrealIRCd, too. (Closes #144)
+  - WHOIS: Not only show RPL_WHOISHOST_MSG to local IRC operators, but show
+    it to all IRC operators in the network. And don't show it to anybody if
+    the "more privacy" configuration option is enabled. (Closes #134)
+  - Test suite: make expect scripts more verbose displaying dots for each
+    reply of the server that it is waiting for.
+  - WHOIS: Implement numeric RPL_WHOISMODES_MSG (379) and show user modes in
+    the reply of the WHOIS command for the user himself or, if MorePrivacy
+    isn't set, for request initiated by an IRC operator. (Closes #129)
+  - Implement channel mode "V" (invite disallow): If the new channel mode
+    "V" is set, the INVITE command becomes invalid and all clients get the
+    new ERR_NOINVITE_MSG (518) reply. (Closes #143)
+  - KICK-protect IRC services.
+  - Implement channel mode "Q" and user mode "q": Both modes protect users
+    from channel kicks: only IRC operators and servers can kick users having
+    mode "q" or in channels with mode "Q". (Closes #141)
+  - Debian: require "telnet" or "telnet-ssl" for building and enable
+    CHARCONV in ngircd-full[-dbg] variants.
+  - Send RPL_REHASHING (382) numeric if a REHASH command was accepted.
+  - Fix spelling and variable names in some log messages.
+  - Allow users to "cloak" their hostname only when the configuration
+    variable "CloakHostModeX" (introduced in 19.2) is set. Otherwise, only
+    IRC operators, other servers, and services are allowed to set the user
+    mode "+x": this prevents regular users from changing their hostmask to
+    the name of the IRC server itself, which confused quite a few people ;-)
+    (Closes #133)
+  - New configuration option "OperChanPAutoOp": If disabled, IRC operators
+    don't become channel operators in persistent channels when joining.
+    Enabled by default, which has been the behavior of ngIRCd up to this
+    patch. (Closes #135)
+  - Allow IRC operators to see secret (+s) channels in LIST command as long
+    as the "MorePrivacy" configuration option isn't enabled in the
+    configuration file. (Closes #136)
+  - Enhance build system: Support new (>=1.12) and old (<=1.11) GNU automake
+    versions, update checks for required and optional features, enable
+    colored test output of automake (if available), rename configure.in to
+    more modern configure.ac, include .mailmap and all build-system files in
+    distribution archives and no longer require a GIT tree to detect the
+    correct version string.
+  - Update documentation: add doc/Contributing.txt and include version
+    numbers in doc/Modes.txt.
+  - Free all listen ports on initialization: now listen ports can be
+    reconfigured on runtime using a configuration reload.
+  - Initialize SSL when needed only, and disable SSL on errors.
+  - Implement new (optional) IRC+ "CHARCONV" command to set a client
+    character set that the server translates all messages to/from UTF-8.
+    This feature requires the "libiconv" library and must be enabled using
+    the new "--with-iconv" option of the ./configure script. See
+    doc/Protocol.txt for details. (Closes #109)
+  - Allow limited punctuation in usernames, for better PAM integration.
+  - Correctly re-initialize signal handlers on RESTART commands.
+  - Show a warning on startup if the configuration file is not a full path:
+    ngIRCd is a long-running process and changes its working directory to
+    "/" to not block mounted filesystems and the like when running as daemon
+    ("not in the foreground"); therefore the path to the configuration file
+    must be relative to "/" (or the chroot() directory), which basically is
+    "not relative", to ensure that "kill -HUP" and the "REHASH" command work
+    as expected later on. (Closes #127)
+  - Make the "&SERVER" channel definable in a [Channel] configuration block,
+    which enables server operators to overwrite the built-in topic and
+    channel modes. (Closes #131)
+  - Don't limit list size of "WHO #channel" commands, because it makes no
+    sense to not return all the users in that channel, so I removed the
+    check. But if there are more than MAX_RPL_WHO(25) replies, the client
+    requesting the list will be "penalized" one second more, then 2 in
+    total. (Closes #125)
+  - Make ngIRCd buildable using the kqueue() IO interface on FreeBSD 4.x.
+  - Fix the "NoticeAuth" configuration option when using SSL connections and
+    enhance the message to show the hostname and IDENT reply of the client.
+  - Introduce numeric RPL_HOSTHIDDEN_MSG (396): This numeric is sent to the
+    client each time it changes its displayed hostname using "MODE +/-x",
+    and if "CloakHost" is set right after the MOTD has been sent.
+  - Fix USERHOST not displaying the correctly cloaked hostname.
+  - Implement user mode "B" ("Bot flag"): it is settable and unsettable by
+    every (non-restricted) client. This is how Unreal and InspIRCd do
+    behave, and so do we :-)
+  - Dynamically allocate memory for connection passwords: This a) saves
+    memory for clients not using passwords at all and b) allows for
+    "arbitrarily" long passwords.
+  - Implement channel mode "M": Only the server, identified users and IRC
+    operators are able to talk in such a channel.
+  - Block nicknames that are reserved for services and are defined using the
+    configuration variable "ServiceMask" in "Server" blocks; And this
+    variable now can handle more than one mask separated by commas.
+  - Now "make uninstall" removes the installed "ngircd.conf" file, if it is
+    still equal to our "sample-ngircd.conf" file and therefore hasn't been
+    modified by the user. If it has been modified, it isn't removed and a
+    notice is displayed to the user. And "make install" now displays a
+    message when no ngircd.conf file exists and the "sample-ngircd.conf"
+    file will be installed as a starting point.
+  - Add contrib/ngircd.service, a systemd service file for ngircd.

+ngIRCd 21~rc1 (2013-10-05)
+
+  - Actually KILL clients on GLINE/KLINE. (Closes bug #156)
+  - Add support to show all user links using the "STATS L" (uppercase)
+    command (restricted to IRC Operators).
+  - Implement configurable SSL cipher list selection for GnuTLS and OpenSSL
+    using the new configuration option "CipherList". In addition, this
+    changes the defaults to more secure values: "HIGH:!aNULL:@STRENGTH" for
+    OpenSSL, and "SECURE128" for GnuTLS.
+  - Show connection flag "s" (SSL) in RPL_TRACE{LINK|SERVER} messages: now
+    you can check if a server-to-server link is SSL-encrypted or not using
+    the IRC "TRACE" command.
+  - Implement the new configuration option "DefaultUserModes" which lists
+    user modes that become automatically set on new local clients right
+    after login. Please note that only modes can be set that the client
+    could set on itself, so you can't set "a" (away) or "o" (IRC Op),
+    for example! User modes "i" (invisible) or "x" (cloaked) etc. are
+    "interesting", though. (Closes bug #160)
+  - Add support for the new METADATA "account" property, which allows
+    services to automatically identify users after netsplits and across
+    service restarts.
+  - Implement a new configuration option "AllowedChannelTypes" that lists
+    all allowed channel types (channel prefixes) for newly created channels
+    on the local server. By default, all supported channel types are allowed.
+    If set to the empty string, local clients can't create new channels at
+    all, which equals the old "PredefChannelsOnly = yes" setting.
+    This change deprecates the "PredefChannelsOnly" variable, too, but it is
+    still supported and translated to the apropriate "AllowedChannelTypes"
+    setting. When the old "PredefChannelsOnly" variable is processed, a
+    warning message is logged. (Closes bug #152)
+  - Add support for "client certificate fingerprinting". When a client
+    passes an SSL certificate to the server, the "fingerprint" will be
+    forwarded in the network which enables IRC services to identify the
+    user using this certificate and not using passwords.
+  - Implement a new configuration option "IncludeDir" in the "[Options]"
+    section that can be used to specify a directory which can contain
+    further configuration files and configuration file snippets matching
+    the pattern "*.conf". These files are read in after the main server
+    configuration file ("ngircd.conf" by default) has been read in and
+    parsed.  The default is "$SYSCONFDIR/ngircd.conf.d", so that it is
+    possible to adjust the configuration only by placing additional files
+    into this directory. (Closes bug #157)
+  - Add Travis-CI configuration file (".travis.yml") to project.
+  - ngIRCd now accepts user names including "@" characters, saves the
+    unmodified name for authentication but stores only the part in front
+    of the "@" character as "IRC user name". And the latter is how
+    ircd2.11, Bahamut, and irc-seven behave as well. (Closes bug #155)
+  - Lots of IRC "information functions" like ADMIN, INFO, ... now accept
+    server masks and names of connected users (in addition to server names)
+    for specifying the target server of the command. (Closes bug #153)
+  - Implement a new configuration option "IdleTimeout" in the "[Limits]"
+    section of the configuration file which can be used to set a timeout
+    in seconds after which the whole daemon will shutdown when no more
+    connections are left active after handling at least one client.
+    The default is 0, "never".
+    This can be useful for testing or when ngIRCd is started using "socket
+    activation" with systemd(8), for example.
+  - Implement support for systemd(8) "socket activation".
+  - Enable WHOIS to display information about IRC Services using the new
+    numeric 310(RPL_WHOISSERVICE) This numeric is used for this purpose by
+    InspIRCd, for example -- but as usual, other numerics are in use, too,
+    like 613 in UltimateIRCd ...
+    Please note that neither the Operator (+o) not the "bot status" (+B)
+    of an IRC service id displayed in the output.
+  - Update systemd(8) example configuration files in ./contrib/ directory:
+    the "ngircd.service" file now uses the "forking" service type which
+    enhances the log messages shown by "systemctl status ngircd.service",
+    and the new "ngircd.socket" file configures a systemd socket that
+    configures a socket for ngIRCd and launches the daemon on demand.
+  - Enhance help system and the HELP command: now a "help text file" can be
+    set using the new configuration option "HelpFile" ("global" section),
+    which is read in and parsed on server startup and configuration reload,
+    and then is used to output individual help texts to specific topics.
+    Please see the file ./doc/Commands.txt for details.
+
+ngIRCd 20.3 (2013-08-23)
+
+  - This release is a bugfix release only, without new features.
+  - Security: Fix a denial of service bug (server crash) which could happen
+    when the configuration option "NoticeAuth" is enabled (which is NOT the
+    default) and ngIRCd failed to send the "notice auth" messages to new
+    clients connecting to the server (CVE-2013-5580).
+
+ngIRCd 20.2 (2013-02-15)
+
+  - This release is a bugfix release only, without new features.
+  - Security: Fix a denial of service bug in the function handling KICK
+    commands that could be used by arbitrary users to to crash the daemon
+    (CVE-2013-1747).
+
+ngIRCd 20.1 (2013-01-02)
+
+  - This release is a bugfix release only, without new features.
+
+ngIRCd 20 (2012-12-17)
+
+  - Allow user names ("INDENT") up to 20 characters when ngIRCd has not
+    been configured for "strict RFC mode". This is useful if you are using
+    external (PAM) authentication mechanisms that require longer user names.
+    Patch suggested by Brett Smith <brett@w3.org>, see
+    <http://arthur.barton.de/pipermail/ngircd-ml/2012-October/000579.html>.
+
+  ngIRCd 20~rc2 (2012-12-02)
+  - Rework cloaked hostname handling and implement the "METADATA cloakhost"
+    subcommand: Now ngIRCd uses two fields internally, one to store the
+    "real" hostname and one to save the "cloaked" hostname. This allows
+    "foreign servers" (aka "IRC services") to alter the real and cloaked
+    hostnames of clients without problems, even when the user itself issues
+    additional "MODE +x" and "MODE -x" commands.
+
+  ngIRCd 20~rc1 (2012-11-11)
+  - Update doc/Services.txt: describe the upcoming version of Anope 1.9.8,
+    then including a protocol module for ngIRCd. And remove our own patches
+    in ./contrib/Anope because they aren't supported any more ...
+  - Implement new "METADATA" command which can be used by remote servers
+    and IRC services to update client metadata like the client info text
+    ("real name"), user name, and hostname, and use this command to
+    configure an cloaked hostname (user mode "+x") on remote servers:
+    This prevents "double cloaking" of hostnames and even cloaked
+    hostnames are in sync on all servers supporting "METADATA" now.
+  - Implement new IRC "SVSNICK" command to allow remote servers (and IRC
+    services) to change nicknames of already registered users. The SVSNICK
+    command itself doesn't change the nickname, but it becomes forwarded
+    to the server to which the user is connected to. And then this server
+    initiates the real nickname changing using regular NICK commands.
+    This allows to run mixed networks with old servers not supporting the
+    SVSNICK command, because SVSNICK commands for nicknames on such servers
+    are silently ignored and don't cause a desynchronization of the network.
+  - New configuration option "MaxListSize" to configure the maximum number
+    of channels returned by a LIST command. The default is 100, as before.
+  - Implement user mode "b", "block messages": when a user has set mode "b",
+    all private messages and notices to this user are blocked if they don't
+    originate from a registered user, an IRC Op, server or service. The
+    originator gets an error numeric sent back in this case,
+    ERR_NONONREG_MSG (486), which is used by UnrealIRCd, too. (Closes #144)
+  - Implement channel mode "V" (invite disallow): If the new channel mode
+    "V" is set, the INVITE command becomes invalid and all clients get the
+    new ERR_NOINVITE_MSG (518) reply. (Closes #143)
+  - Implement channel mode "Q" and user mode "q": Both modes protect users
+    from channel kicks: only IRC operators and servers can kick users having
+    mode "q" or in channels with mode "Q". (Closes #141)
+  - Allow users to "cloak" their hostname only when the configuration
+    variable "CloakHostModeX" (introduced in 19.2) is set. Otherwise, only
+    IRC operators, other servers, and services are allowed to set the user
+    mode "+x": this prevents regular users from changing their hostmask to
+    the name of the IRC server itself, which confused quite a few people ;-)
+    (Closes #133)
+  - New configuration option "OperChanPAutoOp": If disabled, IRC operators
+    don't become channel operators in persistent channels when joining.
+    Enabled by default, which has been the behavior of ngIRCd up to this
+    patch. (Closes #135)
+  - Allow IRC operators to see secret (+s) channels in LIST command as long
+    as the "MorePrivacy" configuration option isn't enabled in the
+    configuration file. (Closes #136)
+  - Implement new (optional) IRC+ "CHARCONV" command to set a client
+    character set that the server translates all messages to/from UTF-8.
+    This feature requires the "libiconv" library and must be enabled using
+    the new "--with-iconv" option of the ./configure script. See
+    doc/Protocol.txt for details. (Closes #109)
+  - Implement user mode "B" ("Bot flag"): it is settable and unsettable by
+    every (non-restricted) client. This is how Unreal and InspIRCd do
+    behave, and so do we :-)
+  - Implement channel mode "M": Only the server, identified users and IRC
+    operators are able to talk in such a channel.
+  - Block nicknames that are reserved for services and are defined using the
+    configuration variable "ServiceMask" in "Server" blocks; And this
+    variable now can handle more than one mask separated by commas.
+  - Implemented XOP channel user modes: "Half Op" ("+h", prefix "%") can set
+    the channel modes +imntvIbek and kick all +v and normal users; "Admin"
+    ("+a", prefix "&") can set channel modes +imntvIbekoRsz and kick all +o,
+    +h, +v and normal users; and "Owner" ("+q", prefix "~") can set channel
+    modes +imntvIbekoRsz and kick all +a, +o, +h, +v and normal users.
+  - Implement hashed cloaked hostnames for both the "CloakHost" and
+    "CloakHostModeX" configuration options: now the admin can use the new
+    '%x' placeholder to insert a hashed version of the clients hostname,
+    and the new configuration option "CloakHostSalt" defines the salt for
+    the hash function. When "CloakHostSalt" is not set (the default), a
+    random salt will be generated after each server restart.

 I. Introduction
 ~~~~~~~~~~~~~~~
 
-ngIRCd is an Open Source server for the Internet Relay Chat (IRC), which
-is developed and published under the terms of the GNU General Public
-Licence, see the file COPYING for details. ngIRCd means "next generation
-IRC daemon" (which is a little bit exaggerated, "lightweight Internet Relay
-Chat server" would be better), it's written from scratch and not deduced
-from the "grandfather of IRC daemons", the daemon of the IRCNet.
+ngIRCd is a free, portable and lightweight Internet Relay Chat server for
+small or private networks, developed under the GNU General Public License
+(GPL; please see the file COPYING for details). It is simple to configure,
+can cope with dynamic IP addresses, and supports IPv6 as well as SSL. It is
+written from scratch and not based on the original IRCd.
+
+The name ngIRCd means next generation IRC daemon, which is a little bit
+exaggerated: lightweight Internet Relay Chat server most probably would be a
+better name :-)
 
 Please see the INSTALL document for installation and upgrade information!

-
-Imagine we had three servers, A, B & C linked like so: A<->B<->C:
-
-If Anope is linked to A and B splits from A and then reconnects B
-introduces itself, introduces C, sends EOS for C, introduces B's clients
-introduces C's clients, sends EOS for B. This causes all of C's clients
-to be introduced with their server "not syncing".
-
-We now send a PING immediately when receiving a new server and then
-finish sync once we get a pong back from that server.

-This directory contains two preliminary patches that (re-) add a ngIRCd
-protocol module to the Anope 1.9 development branch. It has been tested
-with Anope 1.9.6, there is no guarantee that it will work with other
-versions as Anope 1.9.x is under heavy development ...
-
-To build this Anope protocol module, you have to
-
- - Download the Anope 1.9.x sources (only tested with 1.9.6!),
- - Patch in the ngIRCd protocol module,
- - Build and install Anope as usual,
- - Configure Anope as usual, use "ngircd" as protocol module.
-
-So the command sequence can be something like this:
-
- $ tar xzf anope-1.9.6-source.tar.gz
- $ cd anope-1.9.6-source
- $ for p in .../ngircd/contrib/Anope/*.patch ; do patch -p1 < $p ; done
- $ ./Config
- $ cd build
- $ make
- $ make install
-
-Please have a look at the file doc/Services.txt for more information about
-how to set up ngIRCd and Anope.

+
+
+This file lists all commands available on ngIRCd. It is written in a format
+that is human readable as well as machine parseable and therefore can be used
+as "help text file" of the daemon.
+
+In short, the daemon reads this file on startup and parses it as following
+when an user issues a "HELP <cmd>" command:
+
+ 1. Search the file for a line "- <cmd>",
+ 2. Output all subsequent lines that start with a TAB (ASCII 9) character
+    to the client using NOTICE commands, treat lines containing a single "."
+    after the TAB as empty lines.
+ 3. Break at the first line not starting with a TAB character.
+
+This format allows to have information to each command stored in this file
+which will not be sent to an IRC user requesting help which enables us to
+have additional annotations stored here which further describe the origin,
+implementation details, or limits of the specific command which are not
+relevant to an end-user but administrators and developers.
+
+A special "Intro" block is returned to the user when the HELP command is
+used without a command name:
+
+
+- Intro
+	This is ngIRCd, a server software for Internet Relay Chat (IRC)
+	networks. You can find more information about ngIRCd on its homepage:
+		<http://ngircd.barton.de>
+	.
+	Use "HELP COMMANDS" to get a list of all available commands and
+	"HELP <command-name>" to get help for a specific IRC command, for
+	example "HELP quit" or "HELP privmsg".
+
+
+Connection Handling Commands
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- CAP
+	CAP LS
+	CAP LIST
+	CAP REQ <capabilities>
+	CAP ACK <capabilities>
+	CAP NAK <capabilities>
+	CAP CLEAR
+	CAP END
+	.
+	List, request, and clear "IRC Capabilities".
+	.
+	Using this command, an IRC client can request additional "IRC
+	capabilities" during login or later on, which influences the
+	communication between server and client. Normally, these commands
+	aren't directly used by humans, but automatically by their client
+	software. And please note that issuing such commands manually can
+	irritate the client software used, because of the "non-standard"
+	behavior of the server!
+	.
+	- CAP LS: list all available capabilities.
+	- CAP LIST: list active capabilities of this connection.
+	- CAP REQ: Request particular capabilities.
+	- CAP ACK: Acknowledge a set of capabilities to be enabled/disabled.
+	- CAP NAK: Reject a set of capabilities.
+	- CAP CLEAR: Clear all set capabilities.
+	- CAP END: Indicate end of capability negotiation during login,
+	  ignored in an fully registered session.
+
+	Please note that the <capabilities> must be given in a single
+	parameter but whitespace separated, therefore a command could look
+	like this: "CAP REQ :capability1 capability2 capability3" for example.
+
+	References:
+	 - <http://ircv3.atheme.org/specification/capability-negotiation-3.1>
+	 - <http://ngircd.barton.de/doc/Capabilities.txt>
+	 - doc/Capabilities.txt
+
+- CHARCONV
+	CHARCONV <client-charset>
+	.
+	Set client character set encoding to <client-charset>.
+	.
+	After receiving such a command, the server translates all message
+	data received from the client using the set <client-charset> to the
+	server encoding (UTF-8), and all message data which is to be sent to
+	the client from the server encoding (UTF-8) to <client-charset>.
+	.
+	This enables older clients and clients using "strange" character sets
+	to transparently participate in channels and direct messages to
+	clients using UTF-8, which should be the default today.
+
+	References:
+	 - IRC+, <http://ngircd.barton.de/doc/Protocol.txt>
+	 - IRC+, doc/Protocol.txt
+
+- NICK
+	NICK <nickname>
+	NICK <nickname> [<hops>]
+	NICK <nickname> <hops> <username> <host> <servertoken> <usermodes> <realname>
+	.
+	Set or change the <nickname> of a client (first form) and register
+	remote clients (second and third form; servers only).
+
+	References:
+	 - RFC 1459, 4.1.2 "Nick message" (old client and server protocol)
+	 - RFC 2812, 3.1.2 "Nick message" (client protocol)
+	 - RFC 2813, 4.1.3 "Nick" (server protocol)
+
+- PASS
+	PASS <password>
+	PASS <password> <version> <flags> [<options>]
+	.
+	Set a connection <password>. This command must be the first command
+	sent to the server, even before the NICK/USER or SERVER commands.
+	.
+	The first form is used by user sessions or (old) RFC 1459 servers,
+	the second form is used by RFC 2812 or IRC+ compliant servers and
+	enables the server to indicate its version and supported protocol
+	features.
+
+	References:
+	 - RFC 1459, 4.1.1 "Password message" (old client and server protocol)

+
+- PING
+	PING <token> [<target>]
+	.
+	Tests the presence of a connection to a client or server.
+	.
+	If no <target> has been given, the local server is used. User clients
+	can only use other servers as <target>, no user clients.
+	.
+	A PING message results in a PONG reply containing the <token>, which
+	can be arbitrary text.
+
+	Please note:
+	The RFCs state that the <token> parameter is used to specify the
+	origin of the PING command when forwarded in the network, but this
+	is not the case: the sender is specified using the prefix as usual,
+	and the parameter is used to identify the PONG reply in practice.
+
+	References:
+	 - RFC 2812, 3.7.2 "Ping message"
+
+- PONG
+	PONG <target> [<token>]
+	.
+	Reply to a "PING" command, indicate that the connection is alive.
+	.
+	The <token> is the arbitrary text received in the "PING" command and
+	can be used to identify the correct PONG sent as answer.
+	.
+	When the "PONG" command is received from a user session, the <target>
+	parameter is ignored; otherwise the PONG is forwarded to this client.
+
+	References:
+	 - RFC 2812, 3.7.3 "Pong message"
+
+- QUIT
+	QUIT [<quit-message>]
+	.
+	Terminate a user session.
+	.
+	When received from a user, the server acknowledges this by sending
+	an "ERROR" message back to the client and terminates the connection.
+	.
+	When a <quit-message> has been given, it is sent to all the channels
+	that the client is a member of when leaving.
+
+	References:
+	 - RFC 2812, 3.1.7 "Quit"
+	 - RFC 2813, 4.1.5 "Quit"
+
+- USER
+	USER <username> <hostname> <unused> <realname>
+	.
+	Register (and authenticate) a new user session with a short <username>
+	and a human-readable <realname>.
+	.
+	The parameter <hostname> is only used when received by an other server
+	and ignored otherwise; and the parameter <unused> is always ignored.
+	But both parameters are required on each invocation by the protocol
+	and can be set to arbitrary characters/text when not used.
+	.
+	If <username> contains an "@" character, the full <username> is used
+	for authentication, but only the first part up to this character is
+	set as "user name" for this session.
+
+	References:
+	 - RFC 2812, 3.1.3 "User message"
+
+- WEBIRC
+	WEBIRC <password> <username> <hostname> <ip-address>
+	.
+	Allow Web-to-IRC gateway software (for example) to set the correct
+	user name and host name of users instead of their own.
+	.
+	It must be the very first command sent to the server, even before
+	USER and NICK commands!
+	.
+	The <password> must be set in the server configuration file to prevent
+	unauthorized clients to fake their identity; it is an arbitrary string.

+
+General Commands
+~~~~~~~~~~~~~~~~
+
+- AWAY
+	AWAY [<message>]
+	.
+	Provides the server with a message to automatically send in reply to a
+	PRIVMSG directed at the user, but not to a channel they are on.
+	.
+	If <message> is omitted, the away status is removed.
+
+	References:
+	 - RFC 2812, 4.1 "Away"
+
+- HELP
+	HELP [<command>]
+	.
+	Show help information for a specific IRC <command>. The <command> name
+	is case-insensitive.
+	.
+	Use the command "HELP Commands" to get a list of all available commands.
+
+	The HELP command isn't specified by any RFC but implemented by most
+	daemons. If no help text could be read in, ngIRCd outputs a list of all
+	implemented commands when receiving a plain "HELP" command as well as
+	on "HELP Commands".
+
+	ngIRCd replies using "NOTICE" commands like ircd 2.10/2.11; other
+	implementations are using numerics 704, 705, and 706.
+
+- MODE
+	MODE <nickname> [{+|-}<mode>[<mode>] [{+|-}<mode>[<mode>] [...]]]
+	MODE <channel> [{+|-}<mode>[<mode>] [<arg> [<arg> [...]]] [{+|-}<mode>[<mode>] [<arg> [<arg> [...]]] [...]]]
+	.
+	Set and get user and channel modes.
+	.
+	When no mode parameters are given, the currently set user or channel
+	modes are returned. Otherwise the modes are adjusted accordingly
+	and the changes will be reported back to the client.
+	.
+	All user and channel "modes" are indicated by single case-sensitive
+	characters.
+	.
+	Please note that a user can only get and set his own modes, and not
+	all user "levels" are allowed to change all channel modes ...
+	.
+	The mode parameters can become quite complex, especially when dealing
+	with channel modes that require additional arguments:
+	.
+	  {+|-}<mode(s}>  -- set or unset one or more modes.
+	  +<mode(s)> -<mode(s)>  -- set some modes and unset others.
+	  +<modes> <arg1> <arg2>  -- set (at least) two modes with arguments.
+	.
+	Some examples:
+	.
+	  MODE nick +i  -- set user to "invisible".
+	  MODE #chan +tn  -- set "topic lock" and "no external messages".
+	  MODE #chan -t +l 50  -- remove "topic lock", set "user limit" to 50.
+	  MODE #chan +ov nick1 nick2  -- set "channel op" and "voice" mode
+	                                 to nick1 and nick2 in channel #chan.
+	.
+	A complete list of all modes supported by ngIRCd can be found online
+	here: <http://ngircd.barton.de/doc/Modes.txt>.

+	 - RFC 2811, 4. "Channel Modes"

+	 - <http://ngircd.barton.de/doc/Modes.txt>
+	 - doc/Modes.txt
+
+- NOTICE
+	NOTICE <target>[,<target>[,...]] <message>
+	.
+	Send a <message> to a given <target>, which can be a user or a
+	channel, but DON'T report any error.
+	.
+	The "NOTICE" command exactly behaves like the "PRIVMSG" command, but
+	doesn't report any errors it encounters (like an unknown <target>).
+	Please see the help text of the "PRIVMSG" command for a detailed
+	description of the parameters!
+
+	References:
+	 - RFC 2812, 2.3.1 "Message format in Augmented BNF"
+	 - RFC 2812, 3.3 "Sending messages"
+	 - RFC 2812, 3.3.2 "Notice"
+
+- PRIVMSG
+	PRIVMSG <target>[,<target>[,...]] <message>
+	.
+	Send a <message> to a given <target>, which can be a user or a
+	channel, and report all errors.
+	.
+	The <target> must follow one of these syntax variants:
+	.
+	 - <nickname>
+	 - <channel>
+	 - <user>[%<host>]@<server>
+	 - <user>%<host>
+	 - <nickname>!<user>@<host>
+	.
+	If the <target> is a user, a private message is sent directly to this
+	user; if it resolves to a channel name, a public message is sent
+	to all the members of that channel.
+	.
+	In addition, IRC Ops can use these two forms to specify the <target>:
+	.
+	 - #<hostmask>
+	 - #<servermask>
+	.
+	The <mask> can contain the wildcard characters "*" and "?", but must
+	contain at least one dot (".") and no wildcard after the last one.
+	Then, the <message> is sent to all users matching this <mask>.
+	.
+	All warnings and errors are reported back to the initiator using
+	numeric status codes, which is the only difference to the "NOTICE"
+	command, which doesn't report back any errors or warnings at all.
+	.
+	Please note that clients often use "MSG" as an alias to PRIVMSG, and
+	a command "QUERY <nick> [<message>]" to initiate private chats. Both
+	are command extensions of the client and never sent to the server.
+

+	 - RFC 2812, 2.3.1 "Message format in Augmented BNF"

+
+- ADMIN
+	ADMIN [<target>]
+	.
+	Show administrative information about an IRC server in the network.
+	.
+	<target> can be a server name, the nickname of a client connected to
+	a specific server, or a mask matching a server name in the network.
+	The server of the current connection is used when <target> is omitted.
+
+	References:
+	 - RFC 2812, 3.4.9 "Admin command"
+
+- INFO
+	INFO [<target>]
+	.
+	Show the version, birth & online time of an IRC server in the network.

+
+- ISON
+	ISON <nickname> [<nickname> [...]]
+	.
+	Query online status of a list of nicknames. The server replies with
+	a list only containing nicknames actually connected to a server in
+	the network. If no nicknames of the given list are online, an empty
+	list is returned to the client requesting the information.
+
+	Please note that "all" IRC daemons even parse separate nicknames in
+	a single parameter (like ":nick1 nick2"), and therefore ngIRCd
+	implements this behaviour, too.
+
+	References:
+	 - RFC 2812, 4.9 "Ison message"
+
+- LINKS
+	LINKS [[<target>] [<mask>]
+	.
+	List all servers currently registered in the network matching <mask>,

+	services, ...) in the network as seen by the server <target>.
+	.
+	<target> can be a server name, the nickname of a client connected to
+	a specific server, or a mask matching a server name in the network.
+	The server of the current connection is used when <target> is omitted.
+
+	Please note that ngIRCd ignores the <mask> parameter entirely: it
+	is not possible to get information for a part of the network only.

+	References:
+	 - RFC 2812, 3.4.2 "Lusers message"
+
+- MOTD
+	MOTD [<target>]
+	.

+	.
+	Show the list of users that are members of a particular <channel>
+	(and that are visible for the client requesting this information) as
+	seen by the server <target>. More than one <channel> can be given
+	separated by "," (but not whitespaces!).
+	.
+	If <channel> has been omitted, all visible users are shown, grouped
+	by channel name, and all visible users not being members of at least
+	one channel are shown as members of the pseudo channel "*".
+	.
+	<target> can be a server name, the nickname of a client connected to
+	a specific server, or a mask matching a server name in the network.
+	The server of the current connection is used when <target> is omitted.
+
+	References:
+	 - RFC 2812, 3.2.5 "Names message"
+
+- STATS
+	STATS [<query> [<target>]]
+	.
+	Show statistics and other information of type <query> of a particular
+	IRC server in the network.
+	.
+	The following <query> types are supported (case-insensitive where
+	applicable):
+	.
+	 - g  Network-wide bans ("G-Lines").
+	 - k  Server-local bans ("K-Lines").

+
+- TRACE
+	TRACE [<target>]
+	.
+	Find the route to a specific server and send information about its
+	peers. Each server that processes this command reports back to the
+	sender about it: the replies from pass-through servers form a chain
+	which shows the route to the destination.
+	.
+	<target> can be a server name, the nickname of a client connected to
+	a specific server, or a mask matching a server name in the network.
+	The server of the current connection is used when <target> is omitted.
+
+	References:
+	 - RFC 2812, 3.4.8 "Trace message"
+
+- USERHOST
+	USERHOST <nickname> [<nickname> [...]]
+	.

+	(".", for example "ngIRCd-20.1."). If it ends in ".1" (for example
+	"ngIRCd-20.1.1", same version than before!), the server is running in
+	debug-mode; and if it ends in ".2", the "network sniffer" is active!
+	Keep your privacy in mind ...
+
+	References:
+	 - RFC 2812, 3.4.3 "Version message"
+
+- WHO
+	WHO [<mask> ["o"]]
+	.
+	Show a list of users who match the <mask>, or all visible users when

+	References:
+	 - RFC 2812, 3.6.1 "Who query"
+
+- WHOIS
+	WHOIS [<target>] <mask>[,<mask>[,...]]

+	Query information about nicknames no longer in use in the network,
+	either because of nickname changes or disconnects. The history is
+	searched backwards, returning the most recent entry first. If there
+	are multiple entries, up to <count> entries will be shown (or all of
+	them, if no <count> has been given).
+	.
+	<target> can be a server name, the nickname of a client connected to a
+	specific server, or a mask matching a server name in the network. The

+Channel Commands
+~~~~~~~~~~~~~~~~
+
+- INVITE
+	INVITE <nickname> <channel>
+	.
+	Invite <nickname> to join channel <channel>.
+	.
+	<channel> does not have to exist, but if it does, only members of the
+	channel are allowed to invite other users. If the channel mode "+i"
+	is set, only channel "half-ops" (and above) may invite other clients,
+	and if channel mode "+V" is set, nobody can invite other users.
+
+	References:
+	 - RFC 2812, 3.2.7 "Invite message"
+
+- JOIN
+	JOIN {<channel>[,<channel>[,...]] [<key>[,<key>[,...]]] | 0}
+	.
+	Makes the client join the <channel> (comma-separated list), specifying
+	the channel keys ("passwords"). A <channel-key> is only needed if the
+	<channel> has the mode "+k" set.
+	.
+	If the channel(s) do not exist, then they will be created.
+	.
+	Using "JOIN 0" parts all channels at once.

+	.
+	Remove users(s) with <nickname>(s) from <channel>(s).
+	.
+	There must be either exactly one <channel> parameter and multiple
+	<nickname> parameters, or as many <channel> parameters as there are
+	<nickname> parameters. The <reason> is shown to the users being
+	kicked, and the nickname of the current user is used when <reason>

+
+- PART
+	PART <channel>[,<channel>[,...]] [<part-message>]

+	to connect to the server named <server>, which must be configured
+	in the server configuration file.
+	.
+	To use this command, the user must be an IRC Operator. To establish
+	a connection on a <remote-server>, you must have remote IRC operator
+	privileges.
+	.
+	If <port>, <my-pwd> and <peer-pwd> are given, these values override
+	the ones specified in the server configuration file.

+	   of ngIRCd.
+
+- OPER
+	OPER <name> <password>
+	.
+	Authenticates a user named <name> as an IRC operator on the current
+	server/network.
+	.
+	This operator <name> must be configured in the server configuration.

+
+	References:
+	 - RFC 2812, 3.1.4 "Oper message"
+
+- REHASH
+	REHASH

+
+IRC Service Commands
+~~~~~~~~~~~~~~~~~~~~
+
+- SERVICE
+	SERVICE <name> <reserved1> <distribution> <type> <reserved2> <info>
+	SERVICE <name> <servertoken> <distribution> {<type>|+<modes>} <hops> <info>
+	.
+	Register a new service in the network.
+	.
+	The first form is used by directly linked services and isn't supported
+	by ngIRCd at the moment. The second form announces services connected
+	to remote "pseudo-servers" ("services hubs").
+	.
+	The <distribution> and <type> parameters are ignored by ngIRCd.
+
+	References:
+	 - RFC 2812, 3.1.6 "Service message"
+	 - RFC 2813, 4.1.4 "Service message"
+
+- SERVLIST
+	SERVLIST [<mask> [<type>]]
+	.
+	List all IRC services currently registered in the network.
+	.
+	The optional <mask> and <type> parameters can be used to limit the
+	listing to services matching the <mask> and that are of type <type>.
+	.
+	Please note that ngIRCd doesn't use any service types at the moment
+	and therefore all services are of type "0".
+
+	References:
+	 - RFC 2812, 3.5.1 "Servlist message"
+
+- SQUERY
+	SQUERY <target>[,<target>[,...]] <message>
+	.
+	Send a <message> to a given <target> IRC service, and report all
+	errors.
+	.
+	The "SQUERY" command exactly behaves like the "PRIVMSG" command, but
+	enforces that the <target> of the <message> is an IRC service.
+	Please see the help text of the "PRIVMSG" command for a detailed
+	description of the parameters!
+	.
+	If a user wants to interact with IRC services, he should use "SQUERY"
+	instead of "PRIVMSG" or "NOTICE": only "SQUERY makes sure that no
+	regular user, which uses the nickname of an IRC service, receives
+	the command in error, for example during a "net split"!
+
+	References:
+	 - RFC 2812, 2.3.1 "Message format in Augmented BNF"
+	 - RFC 2812, 3.3 "Sending messages"
+	 - RFC 2812, 3.3.2 "Notice"
+
+- SVSNICK
+	SVSNICK <oldnick> <newnick>
+	.
+	Forcefully change foreign user nicknames. This command is allowed
+	for servers only.
+	.
+	The "SVSNICK" command is forwarded to the server to which the user
+	with nickname <oldnick> is connected to, which in turn generates a
+	regular "NICK" command that then is sent to the client, so no special
+	support in the client software is required.

+
+
+Server Protocol Commands
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+- CHANINFO
+	CHANINFO <channel> +<modes> [[<key> <limit>] <topic>]
+	.
+	CHANINFO is used by servers to inform each other about a channel:
+	its modes, channel key, user limits and its topic.
+	.
+	The CHANINFO command is allowed on server-links only.
+
+	References:
+	 - IRC+, <http://ngircd.barton.de/doc/Protocol.txt>
+	 - IRC+, doc/Protocol.txt
+
+- ERROR
+	ERROR [<message> [<> [...]]]
+	.
+	Inform a client or a server about an error condition. The first 
+	parameter, if given, is logged by the server receiving the message,
+	all other parameters are silently ignored.
+	.
+	This command is silently ignored on non-server and non-service links
+	and shouldn't be used by regular IRC clients.
+	.
+	The ERROR message is also sent before terminating a regular client
+	connection.
+
+	References:
+	 - RFC 2812, 3.7.4 "Error message"
+
+- METADATA
+	METADATA <target> <key> <value>
+	.
+	The METADATA command is used on server-links to update "metadata"
+	information of clients, like the hostname, the info text ("real name"),
+	or the user name.
+	.
+	The METADATA command is allowed on server-links only.
+
+	References:
+	 - IRC+, <http://ngircd.barton.de/doc/Protocol.txt>
+	 - IRC+, doc/Protocol.txt
+
+- NJOIN
+	NJOIN <channel> [<mode>]<nick>[,[<mode>]<nick>[,...]]
+	.
+	The NJOIN command is used on server-links to add users with <nick>
+	and <mode> to a <channel> while peering.
+	.
+	The NJOIN command is allowed on server-links only.
+
+	References:
+	 - RFC 2813, 4.2.2 "Njoin message"
+
+- SERVER
+	SERVER <servername> <info>
+	SERVER <servername> <hopcount> <info>
+	SERVER <servername> <hopcount> <token> <info>
+	.
+	The first form registers the local connection as a new server in the
+	network, the second (RFC 1459) and third (RFC 2812) form announce a
+	new remote server in the network.
+	.
+	The SERVER command is allowed on unregistered or server-links only.
+
+	References:
+	 - RFC 1459, 4.1.4 "Server message"
+	 - RFC 2813, 4.1.2 "Server message"
+
+- SQUIT
+	SQUIT <server> <comment>
+	.
+	Disconnects an IRC Server from the network.
+	.
+	This command is used on server-links, but can be used by IRC Operators
+	to forcefully disconnect servers from the network, too.
+
+	References:
+	 - RFC 2812, 3.1.8 "Squit"
+	 - RFC 2813, 4.1.6 "Server quit message"
+
+Dummy Commands
+~~~~~~~~~~~~~~
+
+- SUMMON
+	SUMMON <user> [<target> [<channel>]]
+	.
+	This command was intended to call people into IRC who are directly
+	connected to the terminal console of the IRC server -- but is
+	deprecated today. Therefore ngIRCd doesn't really implement this
+	command and always returns an error message, regardless of the
+	parameters given.
+
+	References:
+	 - RFC 2812, 4.5 "Summon message"
+
+- USERS
+	USERS [<target>]
+	.
+	This command was intended to list users directly logged in into the
+	console of the IRC server -- but is deprecated today. Therefore ngIRCd
+	doesn't really implement this command and always returns an error
+	message, regardless of the parameters given.
+
+	References:
+	 - RFC 2812, 4.6 "Users"

+
+A client can set its character set encoding using the CHARCONV command:

+encoding (UTF-8), and all message data which is to be sent to the client
+from the server encoding (UTF-8) to <client-charset>.

 .SH DESCRIPTION
 .BR ngIRCd
-is a free open source daemon for the Internet Relay Chat (IRC),
-developed under the GNU General Public License (GPL).
+is a free, portable and lightweight Internet Relay Chat server for small
+or private networks, developed under the GNU General Public License (GPL).
+It is easy to configure, can cope with dynamic IP addresses, and supports
+IPv6, SSL-protected connections as well as PAM for authentication.
+It is written from scratch and not based on the original IRCd.
 .PP
-It's written from scratch and is not based upon the original IRCd like
-many others. It is easy to configure, supports server links (even with
-original ircd's) and runs on hosts with changing IP addresses (such as
-dial-in networks).
-.PP
-Currently supported platforms include AIX, A/UX, FreeBSD, HP-UX, IRIX,
-Linux, Mac OS X, NetBSD, OpenBSD, Solaris, and Windows with Cygwin.
+The name ngIRCd means
+.IR "next generation IRC daemon",
+which is a little bit exaggerated:
+.IR "lightweight Internet Relay Chat server"
+most probably would have been a better name :-)
 .PP
+Currently supported platforms include AIX, A/UX, FreeBSD, HP-UX, Hurd, IRIX,
+Linux, Mac OS X, Minix, NetBSD, OpenBSD, Solaris, and Windows with Cygwin.
 As ngIRCd relies on UNIX standards and uses GNU automake and GNU autoconf
 there are good chances that it also supports other UNIX-based operating
-systems as well. By default, ngIRCd writes diagnostic and informational messages using
-the syslog mechanism.
+systems as well.

+By default ngIRCd logs diagnostic and informational messages using the syslog
+mechanism, or writes directly to the console when running in the foreground
