User Mode +g Documentation
|
|
|
|
Support of this specification is indicated by the CALLERID token in
|
|
RPL_ISUPPORT (005). This token takes an optional parameter, of the letter
|
|
of the user mode. If no parameter is specified, the user mode is g. A
|
|
typical token would be: CALLERID=g
|
|
The rest of this specification will assume the user mode is g, as
|
|
implemented in hybrid, ratbox and charybdis.
|
|
|
|
Hybrid 7 includes a new and power feature that all users can take advantage
|
|
of to help prevent flooding and unwanted messages. This new feature is
|
|
invoked by setting user mode +g. When a client is set +g, that user will
|
|
be in "Caller ID" mode. Any user that messages a +g client will receive
|
|
a notice saying that they are in +g (server side ignore) mode. The target
|
|
client (who is set +g) will also receive a notice saying that so and so
|
|
messaged them, and that they are in +g mode.
|
|
|
|
The target of the message will only receive one notification per minute, from
|
|
any client, in order to help prevent flooding. The sender will NOT have the
|
|
rate limit, and will receive a numeric saying the target is in +g mode every
|
|
time they send a message. Note that this behavior is similar to the way AWAY
|
|
messages are done.
|
|
|
|
There are numerous benefits for both opers and regular users, including the
|
|
ability to stop spambot messages from ever reaching your client, stopping
|
|
private message and CTCP floods, and being able to sit on IRC in privacy.
|
|
|
|
One question that arises is how to message specific users, while blocking
|
|
out everyone else. The command ACCEPT is your answer. To add a user to
|
|
your accept list, issue the raw command ACCEPT <nick>,<nick>,<nick>,...
|
|
|
|
You will not receive a reply from the ACCEPT command if it is succesful,
|
|
only if an error has occured. There are three possible errors, shown by
|
|
numerics:
|
|
|
|
ERR_ACCEPTFULL (456): :irc.server 456 client :Accept list is full
|
|
- This is sent when an accept list is full.
|
|
ERR_ACCEPTEXIST (457): :irc.server 457 client target :already exists
|
|
- This is sent when a client tries to add a user to the accept list
|
|
that already exists there
|
|
ERR_ACCEPTNOT (458): :irc.server 458 client target :doesnt exist
|
|
- This is sent when a client tries to remove a user from their accept
|
|
list who is not on the accept list.
|
|
|
|
That user will now be able to send messages to your client until the
|
|
association is broken.
|
|
|
|
Associations break in one of the following situations: when an accepted user
|
|
QUIT's (or is on the other side of a split), you QUIT, or the accepted user
|
|
changes their nick. The reason why a remote user's nick change will remove
|
|
them from your accept list is so that you cannot track a user after they
|
|
changed their nick.
|
|
|
|
Viewing the accept list is also very easy. Issue the raw command ACCEPT *.
|
|
Removing a user from your accept list is also simple. Issue the command
|
|
ACCEPT -<nick>.
|
|
|
|
The ACCEPT command can be used whether or not +g is enabled at the time.
|
|
Setting -g does not clear the accept list.
|
|
|
|
Some users (in particular IRC operators and services) may be exempt from
|
|
CallerID, and able to message a +g user without being on their accept list.
|
|
|
|
Being on the accept list may allow a user to bypass more than +g (for example,
|
|
a +R user can use the ACCEPT command to receive messages from unidentified
|
|
users in charybdis).
|
|
|
|
Sample Session
|
|
|
|
The easiest way to see how this works is by experiencing it. Seeing a sample
|
|
session can help understand what goes on though.
|
|
|
|
Client Hwy-LL is set +g initially.
|
|
Client Hwy101 wants to message Hwy-LL
|
|
|
|
Note that some clients may have to use /quote ACCEPT instead of /accept.
|
|
|
|
--
|
|
|
|
Client Hwy101: /msg Hwy-LL hi
|
|
Hwy101 will see: -!- Hwy-LL is in +g mode and must manually allow you to message them.
|
|
-!- Hwy-LL has been informed that you messaged them.
|
|
|
|
Hwy-LL will see: -!- Hwy101 wcampbel@admin.irc.monkie.org is messaging you, and you have umode +g.
|
|
|
|
--
|
|
|
|
If Hwy101 sends another message to Hwy-LL (before the minute expires), he will
|
|
see: -!- Hwy-LL is in +g mode and must manually allow you to message them.
|
|
and will not receive the second notice
|
|
|
|
Hwy-LL will NOT see any notice. This also applies if the second message comes
|
|
from a different user.
|
|
|
|
--
|
|
|
|
Hwy-LL now wishes to see messages from Hwy101 and SpamBot
|
|
|
|
Client Hwy-LL: /accept Hwy101,SpamBot
|
|
|
|
Neither side will be told of the change in the accept list, Hwy-LL should
|
|
presume that the accept was succesful if no error occurs.
|
|
|
|
Now Hwy-LL can see messages from Hwy101 and SpamBot without any blockage.
|
|
If Hwy101 was also set +g, then he would have to issue /accept Hwy-LL
|
|
before he would be able to see messages from Hwy-LL.
|
|
|
|
--
|
|
|
|
Hwy-LL now wants to see who is on his accept list.
|
|
|
|
Client Hwy-LL: /accept *
|
|
|
|
Hwy-LL will see:
|
|
irc.server 281 Hwy-LL Hwy101 SpamBot
|
|
irc.server 282 Hwy-LL :End of /ACCEPT list
|
|
|
|
The replies are in numeric form to help parsing by scripts.
|
|
--
|
|
|
|
Hwy-LL realises he added a spambot to his list, and wants to remove it, and
|
|
allow messages from services
|
|
|
|
Client Hwy-LL: /accept -SpamBot,services
|
|
|
|
Hwy-LL will now only accept messages from Hwy101 and services.
|
|
|

|
|
The nicks to be added can be in ANY order, however you cannot add or remove
|
|
AND list.
|
|
/ACCEPT x,y,-z,f,-a would be acceptable.
|
|
/ACCEPT x,y,-z,* would ignore the * and generate an invalid nick
|
|
response.
|
|
|
|
Like Dalnet and Undernet's SILENCE system, the accept list only exists while
|
|
you are connected to IRC. In order for you to have the same accept list
|
|
every time you come onto IRC, you must put the accept commands into your
|
|
client's auto-perform, or manually issue the commands each time.
|
|
|
|
This system may seem similar to the SILENCE system, but it is actually a
|
|
reverse SILENCE. SILENCE ignores certain users and allows the rest. Mode
|
|
+g ignores all users except certain ones (on your accept list.) Both systems
|
|
have their place, but the mode +g in Hybrid 7 is what the developers thought
|
|
would be most useful for clients.
|
|
|
|
The goals of this user mode is to provide protection from flooding and
|
|
spamming, and to provide users with a means to keep their privacy.
|
|
|
|
We hope that these goals are obtained.

Numeric replies
|
|
---------------
|
|
|
|
280 - RPL_ACCEPTLIST
|
|
--------------------
|
|
:<server> 280 <nick> <accepted1> <accepted2> ...
|
|
|
|
This numeric is used to indicate to a client the list of nicknames they are
|
|
accepting. At most 15 accepted nicknames may be included; if this is exceeded
|
|
multiple RPL_ACCEPTLIST must be sent.
|
|
|
|
281 - RPL_ENDOFACCEPT
|
|
---------------------
|
|
:<server> 281 <nick> :End of /ACCEPT list.
|
|
|
|
This numeric is used to indicate to a client the end of an accept list.
|
|
|
|
456 - ERR_ACCEPTFULL
|
|
--------------------
|
|
:<server> 456 <nick> :Accept list is full
|
|
|
|
This numeric is used to indicate to a client that their accept list is full
|
|
and one or more nicks could not be added.
|
|
|
|
457 - ERR_ACCEPTEXIST
|
|
---------------------
|
|
:<server> 457 <nick> <target> :is already on your accept list
|
|
|
|
This numeric is used to indicate to a client that the given nick was already
|
|
on their accept list.
|
|
|
|
458 - ERR_ACCEPTNOT
|
|
-------------------
|
|
:<server> 458 <nick> <target> :is not on your accept list
|
|
|
|
This numeric is used to indicate to a client that the given nick was not on
|
|
their accept list.
|
|
|
|
716 - ERR_TARGUMODEG
|
|
--------------------
|
|
:<server> 716 <nick> <target> :is in +g mode and must manually allow you to message them.
|
|
|
|
This numeric is used to indicate that a message (PRIVMSG) the client sent
|
|
could not be delivered because of CallerID restrictions. The <target>
|
|
parameter is the target user's nick.
|
|
|
|
717 - RPL_TARGNOTIFY
|
|
--------------------
|
|
:<server> 717 <nick> <target> :has been informed that you messaged them.
|
|
|
|
This numeric is sent after 716 if the target user was notified of the message.
|
|
|
|
718 - RPL_UMODEGMSG
|
|
-------------------
|
|
:<server> 718 <nick> <target> <user>@<host> :is messaging you, and you have umode +g.
|
|
|
|
This numeric is sent when a message (PRIVMSG or NOTICE) sent to the user is
|
|
blocked by CallerID, at most once per minute.
|
|
|
|
Problem: hybrid uses the following form instead
|
|
:<server> 718 <nick> <target>[<user>@<host>] :is messaging you, and you have umode +g.
|
|
which is ambiguous if the user may contain a [ and in the author's opinion ugly.
