User modes
|
|
==========
|
|
|
|
``+a``, server administrator
|
|
----------------------------
|
|
|
|
This vanity usermode is used to denote a server administrator in WHOIS
|
|
output. All local “admin” privileges are independent of it, though
|
|
services packages may grant extra privileges to ``+a`` users.
|
|
|
|
``+D``, deaf
|
|
------------
|
|
|
|
.. note:: This is a user umode, which anybody can set. It is not
|
|
specific to operators.
|
|
|
|
Users with the ``+D`` umode set will not receive messages sent to channels.
|
|
Joins, parts, topic changes, mode changes, etc are received as normal,
|
|
as are private messages.
|
|
|
|
Support of this umode is indicated by the ``DEAF`` token in ``RPL_ISUPPORT``
|
|
(005); the parameter indicates the letter of the umode. Note that
|
|
several common IRCD implementations have an umode like this (typically
|
|
``+d``) but do not have the token in 005.
|
|
|
|
``+g``, Caller ID
|
|
-----------------
|
|
|
|
.. note:: This is a user umode, which anybody can set. It is not
|
|
specific to operators.
|
|
|
|
Users with the ``+g`` umode set will only receive private messages
|
|
from users on a session-defined whitelist, defined by the ``/accept``
|
|
command. If a user who is not on the whitelist attempts to send a
|
|
private message, the target user will receive a rate-limited notice
|
|
saying that the user wishes to speak to them.
|
|
|
|
Network operators are not affected by the callerid whitelist system in
|
|
the event that they need to speak to users who have it enabled.
|
|
|
|
Support of this umode is indicated by the ``CALLERID`` token in
|
|
``RPL_ISUPPORT`` (005); the optional parameter indicates the letter of
|
|
the umode, otherwise ``+g``.
|
|
|
|
``+i``, invisible
|
|
-----------------
|
|
|
|
.. note:: This is a user umode, which anybody can set. It is not
|
|
specific to operators.
|
|
|
|
Invisible users do not show up in ``WHO`` and ``NAMES`` unless you can see them.
|
|
|
|
``+l``, receive locops
|
|
----------------------
|
|
|
|
``LOCOPS`` is a version of ``OPERWALL`` that is sent to opers on a single server
|
|
only. With cluster{} and shared{} blocks they can optionally be
|
|
propagated further.
|
|
|
|
Unlike ``OPERWALL``, any oper can send and receive ``LOCOPS``.
|
|
|
|
``+o``, operator
|
|
----------------
|
|
|
|
This indicates global operator status.
|
|
|
|
``+Q``, disable forwarding
|
|
--------------------------
|
|
|
|
.. note:: This is a user umode, which anybody can set. It is not
|
|
specific to operators.
|
|
|
|
This umode prevents you from being affected by channel forwarding. If
|
|
enabled on a channel, channel forwarding sends you to another channel if
|
|
you could not join. See channel mode ``+f`` for more information.
|
|
|
|
``+R``, reject messages from unauthenticated users
|
|
--------------------------------------------------
|
|
|
|
.. note:: This is a user umode, which anybody can set. It is not
|
|
specific to operators.
|
|
|
|
If a user has the ``+R`` umode set, then any users who are not authenticated
|
|
will receive an error message if they attempt to send a private message
|
|
or notice to the ``+R`` user.
|
|
|
|
Opers and accepted users (like in ``+g``) are exempt. Unlike ``+g``, the target
|
|
user is not notified of failed messages.
|
|
|
|
``+s``, receive server notices
|
|
------------------------------
|
|
|
|
This umode allows an oper to receive server notices. The requested types
|
|
of server notices are specified as a parameter (“snomask”) to this
|
|
umode.
|
|
|
|
``+S``, network service
|
|
-----------------------
|
|
|
|
.. note:: This umode can only be set by servers named in a service{}
|
|
block.
|
|
|
|
This umode grants various features useful for services. For example,
|
|
clients with this umode cannot be kicked or deopped on channels, can
|
|
send to any channel, do not show channels in ``WHOIS``, can be the target of
|
|
services aliases and do not appear in ``/stats p``. No server notices are
|
|
sent for hostname changes by services clients; server notices about
|
|
kills are sent to snomask ``+k`` instead of ``+s``.
|
|
|
|
The exact effects of this umode are variable; no user or oper on an
|
|
actual charybdis server can set it.
|
|
|
|
``+w``, receive wallops
|
|
-----------------------
|
|
|
|
.. note:: This is a user umode, which anybody can set. It is not
|
|
specific to operators.
|
|
|
|
Users with the ``+w`` umode set will receive ``WALLOPS`` messages sent by opers.
|
|
Opers with ``+w`` additionally receive ``WALLOPS`` sent by servers (e.g. remote
|
|
``CONNECT``, remote ``SQUIT``, various severe misconfigurations, many services
|
|
packages).
|
|
|
|
``+z``, receive operwall
|
|
------------------------
|
|
|
|
``OPERWALL`` differs from ``WALLOPS`` in that the ability to receive such
|
|
messages is restricted. Opers with ``+z`` set will receive ``OPERWALL``
|
|
messages.
|
|
|
|
``+Z``, SSL user
|
|
----------------
|
|
|
|
This umode is set on clients connected via SSL/TLS. It cannot be set or
|
|
unset after initial connection.
|
|
|
|
Snomask usage
|
|
~~~~~~~~~~~~~
|
|
|
|
Usage is as follows::
|
|
|
|
MODE nick +s +/-flags
|
|
|
|
To set snomasks.
|
|
|
|
::
|
|
|
|
MODE nick -s
|
|
|
|
To clear all snomasks.
|
|
|
|
Umode ``+s`` will be set if at least one snomask is set.
|
|
|
|
Umode ``+s`` is oper only by default, but even if you allow nonopers to set
|
|
it, they will not get any server notices.
|
|
|
|
Meanings of server notice masks
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
``+b``, bot warnings
|
|
--------------------
|
|
|
|
Opers with the ``+b`` snomask set will receive warning messages from the
|
|
server when potential flooders and spambots are detected.
|
|
|
|
``+c``, client connections
|
|
--------------------------
|
|
|
|
Opers who have the ``+c`` snomask set will receive server notices when
|
|
clients attach to the local server.
|
|
|
|
``+C``, extended client connection notices
|
|
------------------------------------------
|
|
|
|
Opers who have the ``+C`` snomask set will receive server notices when
|
|
clients attach to the local server. Unlike the ``+c`` snomask, the
|
|
information is displayed in a format intended to be parsed by scripts,
|
|
and includes the two unused fields of the ``USER`` command.
|
|
|
|
``+d``, debug
|
|
-------------
|
|
|
|
The ``+d`` snomask provides opers extra information which may be of interest
|
|
to debuggers. It will also cause the user to receive server notices if
|
|
certain assertions fail inside the server. Its precise meaning is
|
|
variable. Do not depend on the effects of this snomask as they can and
|
|
will change without notice in later revisions.
|
|
|
|
``+f``, full warning
|
|
--------------------
|
|
|
|
Opers with the ``+f`` snomask set will receive notices when a user
|
|
connection is denied because a connection limit is exceeded (one of the
|
|
limits in a class{} block, or the total per-server limit settable with
|
|
``/quote set max``).
|
|
|
|
``+F``, far client connection notices
|
|
-------------------------------------
|
|
|
|
.. note:: This snomask is only available if the ``sno_farconnect.so``
|
|
extension is loaded.
|
|
|
|
Opers with ``+F`` receive server notices when clients connect or disconnect
|
|
on other servers. The notices have the same format as those from the ``+c``
|
|
snomask, except that the class is ? and the source server of the notice
|
|
is the server the user is/was on.
|
|
|
|
No notices are generated for netsplits and netjoins. Hence, these
|
|
notices cannot be used to keep track of all clients on the network.
|
|
|
|
There is no far equivalent of the ``+C`` snomask.
|
|
|
|
``+k``, server kill notices
|
|
---------------------------
|
|
|
|
Opers with the ``+k`` snomask set will receive server notices when services
|
|
kill users and when other servers kill and save (forced nick change to
|
|
UID) users. Kills and saves by this server are on ``+d`` or ``+s``.
|
|
|
|
``+n``, nick change notices
|
|
---------------------------
|
|
|
|
An oper with ``+n`` set will receive a server notice every time a local user
|
|
changes their nick, giving the old and new nicks. This is mostly useful
|
|
for bots that track all users on a single server.
|
|
|
|
``+r``, notices on name rejections
|
|
----------------------------------
|
|
|
|
Opers with this snomask set will receive a server notice when somebody
|
|
tries to use an invalid username, or if a dumb HTTP proxy tries to
|
|
connect.
|
|
|
|
``+s``, generic server notices
|
|
------------------------------
|
|
|
|
This snomask allows an oper to receive generic server notices. This
|
|
includes kills from opers (except services).
|
|
|
|
``+u``, unauthorized connections
|
|
--------------------------------
|
|
|
|
This snomask allows an oper to see when users try to connect who do not
|
|
have an available auth{} block.
|
|
|
|
``+W``, whois notifications
|
|
---------------------------
|
|
|
|
.. note:: This snomask is only available if the ``sno_whois.so``
|
|
extension is loaded.
|
|
|
|
Opers with ``+W`` receive notices when a ``WHOIS`` is executed on them on their
|
|
server (showing idle time).
|
|
|
|
``+x``, extra routing notices
|
|
-----------------------------
|
|
|
|
Opers who have the ``+x`` snomask set will get notices about servers
|
|
connecting and disconnecting on the whole network. This includes all
|
|
servers connected behind the affected link. This can get rather noisy
|
|
but is useful for keeping track of all linked servers.
|
|
|
|
``+y``, spy
|
|
-----------
|
|
|
|
Opers with ``+y`` receive notices when users try to join ``RESV``'ed (“juped”)
|
|
channels. Additionally, if certain extension modules are loaded, they
|
|
will receive notices when special commands are used.
|
|
|
|
``+Z``, operspy notices
|
|
-----------------------
|
|
|
|
Opers with ``+Z`` receive notices whenever an oper anywhere on the network
|
|
uses operspy.
|
|
|
|
This snomask can be configured to be only effective for admins.
|
