NickServ allows you to "register" a nickname
and prevent others from using it. If the nick is not used for 30
days, the registration will expire. The following commands allow
for registration and maintenance of nicknames; to use them, type
/nickserv command. For more information on a
specific command, type /nickserv HELP command.
- REGISTER
- Register a nickname
- IDENTIFY
- Identify yourself with your password
- ACCESS
- Modify the list of authorized addresses
- LINK
- Make your nick an alias for another
- SET
- Set options, including kill protection
- DROP
- Cancel the registration of a nickname
- RECOVER
- Kill another user who has taken your nick
- RELEASE
- Regain custody of your nick after RECOVER
Other commands: UNLINK, GHOST, INFO, LIST, STATUS
NOTICE: This service is intended to provide a way for
IRC users to ensure their identity is not compromised. It is NOT
intended to facilitate "stealing" of nicknames or
other malicious actions. Abuse of NickServ will result in, at
minimum, loss of the abused nickname(s).
[Top]

REGISTER
- Syntax:
- REGISTER password
Registers your nickname in the NickServ database. Once your
nick is registered, you can use the SET
and ACCESS commands to
configure your nick's settings as you like them. Make sure you
remember the password you use when registering - you'll need it
to make changes to your nick later. (Note that case matters!
FIDO, Fido, and fido are all different
passwords!)
Guidelines on choosing passwords:
Passwords should not be easily guessable. For example, using
your real name as a password is a bad idea. Using your nickname
as a password is a much worse idea ;) and, in fact, NickServ
will not allow it. Also, short passwords are vulnerable to
trial-and-error searches, so you should choose a password at
least 5 characters long. Finally, the space character cannot be
used in passwords.
[Top]

IDENTIFY
- Syntax:
- IDENTIFY password
Tells NickServ that you are really the owner of this nick.
Many commands require you to authenticate yourself with this
command before you use them. The password should be the same one
you sent with the REGISTER
command.
[Top]

DROP
- Syntax:
- DROP
Drops your nickname from the NickServ database. A nick that
has been dropped is free for anyone to re-register.
In order to use this command, you must first identify with
your password (/nickserv HELP
IDENTIFY for more information).
[Top]

ACCESS
- Syntax:
- ACCESS ADD mask
ACCESS DEL mask
ACCESS LIST
Modifies or displays the access list for your nick. This is
the list of addresses which will be automatically recognized by
NickServ as allowed to use the nick. If you want to use the nick
from a different address, you need to send an IDENTIFY
command to make NickServ recognize you.
- Examples:
-
- ACCESS ADD achurch@*.dragonfire.net
- Allows access to user achurch from any machine
in the dragonfire.net domain.
- ACCESS DEL achurch@*.dragonfire.net
- Reverses the previous command.
- ACCESS LIST
- Displays the current access list.
[Top]

LINK
- Syntax:
- LINK nick password
Links your nickname to another, effectively making the nick
you are currently using an alias for the given nick. When you
give this command, the access list for the nick you are using is
deleted and replaced by that of the nick you are linking to; all
memos for your current nick are added to the list of memos for
the target nick (this may cause the nick to exceed its limit of
memos, in which case you will need to delete some before you can
receive more for either nick).
Once the link has been established, your nick will be
transparently converted into the target nick everywhere in
Services, except for the NickServ UNLINK
and DROP commands. For example,
you can use either nick to read the same set of memos (and memos
sent to either nick will go into the same list). If you identify
for one nick, you will automatically be identified for the other
as well. If either nick is on a channel's access list, then both
nicks will get the same access privileges.
In order to use this command, you must identify for your
current nick (using the IDENTIFY
command), and you must supply the password for the nick you wish
to link to.
[Top]

UNLINK
- Syntax:
- UNLINK [nick pass]
Removes a link from your nick to another. When the link is
removed, the nickname flags and access list of the previously
linked nick are copied to your current nick and can then be
independently changed. Memos are not copied; all memos will
remain stored with the previously linked nick.
By giving a nickname and password as parameters, you can
unlink a nick besides the one you are currently using.
[Top]

SET
- Syntax:
- SET option parameters
Sets various nickname options. option can be one of:
- PASSWORD
- Set your nickname password
- LANGUAGE
- Set the language Services will use when sending messages
to you
- URL
- Associate a URL with your nickname
- EMAIL
- Associate an E-mail address with your nickname
- KILL
- Turn kill protection on or off
- SECURE
- Turn nickname security on or off
- PRIVATE
- Prevent your nickname from appearing in a /nickserv
LIST
- HIDE
- Hide certain pieces of nickname information
In order to use this command, you must first identify with your
password (/nickserv HELP IDENTIFY
for more information).
Type /nickserv HELP SET option for more
information on a specific option.
[Top]

SET PASSWORD
- Syntax:
- SET PASSWORD new-password
Changes the password used to identify you as the nick's
owner.
[Top]

SET LANGUAGE
- Syntax:
- SET LANGUAGE number
Changes the language Services uses when sending messages to
you (for example, when responding to a command you send). number
should be chosen from the following list of supported languages:
[Top]

SET URL
- Syntax:
- SET URL url
Associates the given URL with your nickname. This URL will be
displayed whenever someone requests information on your nick
with the INFO command.
[Top]

SET EMAIL
- Syntax:
- SET EMAIL address
Associates the given E-mail address with your nickname. This
address will be displayed whenever someone requests information
on the channel with the INFO
command.
[Top]

SET KILL
- Syntax:
- SET KILL {ON | QUICK | IMMED | OFF}
Turns the automatic kill protection option for your nick on
or off. With kill protection on, if another user tries to take
your nick, they will be given one minute to change to another
nick, after which they will be forcibly removed from IRC by
NickServ.
If you select QUICK, the user will be given only 20
seconds to change nicks instead of the usual 60. If you select IMMED,
the user will be killed immediately without being warned
first or given a chance to change their nick; please do not use
this option unless necessary. Also, your network's
administrators may have disabled this option.
[Top]

SET SECURE
- Syntax:
- SET SECURE {ON | OFF}
Turns NickServ's security features on or off for your nick.
With SECURE set, you must
enter your password before you will be recognized as the owner
of the nick, regardless of whether your address is on the access
list. However, if you are on the access list, NickServ will not
auto-kill you regardless of the setting of the KILL
option.
[Top]

SET PRIVATE
- Syntax:
- SET PRIVATE {ON | OFF}
Turns NickServ's privacy option on or off for your nick. With
PRIVATE set, your
nickname will not appear in nickname lists generated with
NickServ's LIST command.
(However, anyone who knows your nickname can still get
information on it using the INFO
command.)
[Top]

SET HIDE
- Syntax:
- SET HIDE {EMAIL | USERMASK | QUIT} {ON | OFF}
Allows you to prevent certain pieces of information from
being displayed when someone does a NickServ INFO
on your nick. You can hide your E-mail address (EMAIL),
last seen user@host mask (USERMASK), and last quit
message (QUIT). The second parameter specifies whether
the information should be displayed (OFF) or hidden (ON).
[Top]

RECOVER
- Syntax:
- RECOVER nickname [password]
Allows you to recover your nickname if someone else has taken
it; this does the same thing that NickServ does automatically if
someone tries to use a kill-protected nick.
When you give this command, NickServ will bring a fake user
online with the same nickname as the user you're trying to
recover your nick from. This causes the IRC servers to
disconnect the other user. This fake user will will remain
online for one minute to ensure that the other user does not
immediately reconnect; after that minute, you can reclaim your
nick. Alternatively, use the RELEASE
command (/nickserv HELP RELEASE)
to get the nick back sooner.
In order to use the RECOVER
command for a nick, your current address as shown in /WHOIS must
be on that nick's access list, or you must supply the correct
password for the nickname.
[Top]

RELEASE
- Syntax:
- RELEASE nickname [password]
Instructs NickServ to remove any hold on your nickname caused
by automatic kill protection or use of the RECOVER
command. By default, such holds last for one minute; this
command gets rid of them sooner.
In order to use the RELEASE
command for a nick, your current address as shown in /WHOIS must
be on that nick's access list, or you must supply the correct
password for the nickname.
[Top]

GHOST
- Syntax:
- GHOST nickname [password]
Terminates a "ghost" IRC session using your nick. A
"ghost" session is one which is not actually
connected, but which the IRC server believes is still online for
one reason or another. Typically, this happens if your computer
crashes or your Internet or modem connection goes down while
you're on IRC.
In order to use the GHOST
command for a nick, your current address as shown in /WHOIS must
be on that nick's access list, or you must supply the correct
password for the nickname.
[Top]

INFO
- Syntax:
- INFO nickname
Displays information about the given nickname, such as the
nick's owner, last seen address and time, and nick options.
[Top]

LIST
- Syntax:
- LIST pattern
Lists all registered nicknames which match the given pattern,
in nick!user@host format. Nicks with the PRIVATE
option set will not be displayed.
- Examples:
-
- LIST *!joeuser@foo.com
- Lists all nicks owned by joeuser@foo.com.
- LIST *Bot*!*@*
- Lists all registered nicks with Bot in their
names (case insensitive).
- LIST *!*@*.bar.org
- Lists all nicks owned by users in the bar.org
domain.
[Top]

STATUS
- Syntax:
- STATUS nickname...
Returns whether the user using the given nickname is
recognized as the owner of the nickname. The response has this
format:
nickname status-code
where nickname is the nickname sent with the command, and
status-code is one of the following:
- 0
- no such user online or nickname not registered
- 1
- user not recognized as nickname's owner
- 2
- user recognized as owner via access list only
- 3
- user recognized as owner via password identification
Up to sixteen nicknames may be sent with each command; the rest
will be ignored. No error message is generated if no nickname is
given.

REGISTER
- Syntax:
- REGISTER channel password description
Registers a channel in the ChanServ database. In order to use
this command, you must first be a channel operator on the
channel you're trying to register. The password is used with the
IDENTIFY command to allow
you to make changes to the channel settings at a later time. The
last parameter, which must be included, is a general
description of the channel's purpose.
When you register a channel, you are recorded as the
"founder" of the channel. The channel founder is
allowed to change all of the channel settings for the channel;
ChanServ will also automatically give the founder
channel-operator privileges when s/he enters the channel. See
the ACCESS command (/msg
ChanServ HELP ACCESS) for information on giving a subset
of these privileges to other channel users.
NOTICE: In order to register a channel, you must have first
registered your nickname. If you haven't, /nickserv HELP
for information on how to do so.
[Top]

- Syntax:
- SET channel FOUNDER nick
Changes the founder of a channel. The new nickname must be a
registered one.
[Top]

SET SUCCESSOR
- Syntax:
- SET channel SUCCESSOR nick
Changes the successor of a channel. If the founder's nickname
expires or is dropped while the channel is still registered, the
successor will become the new founder of the channel. However,
if the successor already has too many channels registered (0),
the channel will be dropped instead, just as if no successor had
been set. The new nickname must be a registered one.
[Top]

SET PASSWORD
- Syntax:
- SET channel PASSWORD password
Sets the password used to identify as the founder of the
channel.
[Top]

SET URL
- Syntax:

with the INFO command. If no
parameter is given, deletes any current URL for the channel.
[Top]

SET EMAIL
- Syntax:
- SET channel EMAIL [address]
Associates the given E-mail address with the channel. This
address will be displayed whenever someone requests information
on the channel with the INFO
command. If no parameter is given, deletes any current E-mail
address for the channel.
[Top]

SET ENTRYMSG
- Syntax:
- SET channel ENTRYMSG [message]
Sets the message which will be sent via /notice to users when
they enter the channel. If no parameter is given, causes no
message to be sent upon entering the channel.
[Top]

SET TOPIC
- Syntax:
- SET channel TOPIC topic
Causes ChanServ to set the channel topic to the one
specified. This command is most useful in conjunction with SET
TOPICLOCK.
[Top]

SET KEEPTOPIC
- Syntax:
- SET channel KEEPTOPIC {ON | OFF}
Enables or disables the topic retention option for a
channel. When topic retention is set, the topic for the
channel will be remembered by ChanServ even after the last user
leaves the channel, and will be restored the next time the
channel is created.
[Top]

SET TOPICLOCK
- Syntax:
- SET channel TOPICLOCK {ON | OFF}
Enables or disables the topic lock option for a
channel. When topic lock is set, ChanServ will not allow
the channel topic to be changed except via the SET
TOPIC command.
[Top]

SET MLOCK
- Syntax:
- SET channel MLOCK modes
Sets the mode-lock parameter for the channel. ChanServ allows
you to define certain channel modes to be always on (or off).
The modes that can be locked are i, k, l, m,
n, p, s, and t; each of these modes
can be locked on, locked off, or not locked. The modes
parameter is constructed exactly the same way as a /MODE
command; that is, modes followed by a + are locked on, and modes
followed by a - are locked off.
Warning: If you set a mode-locked key, as in the
second example below, you should also set the RESTRICTED
option for the channel (see HELP
SET RESTRICTED), or anyone entering the channel when it
is empty will be able to see the key!
- Examples:
-
- SET #channel MLOCK +nt-iklps
- Forces modes n and t on, and modes i, k, l, p, and s
off. Mode m is left free to be either on or off.
- SET #channel MLOCK +knst-ilmp my-key
- Forces modes k, n, s, and t on, and modes i, l, m, and
p off. Also forces the channel key to be
"my-key".
- SET #channel MLOCK +
- Removes the mode lock; all channel modes are free to
be either on or off.
[Top]

SET PRIVATE
- Syntax:
- SET channel PRIVATE {ON | OFF}
Enables or disables the private option for a channel.
When private is set, a /chanserv LIST will not
include the channel in any lists.
[Top]

SET RESTRICTED
- Syntax:
- SET channel RESTRICTED {ON | OFF}
Enables or disables the restricted access option for a
channel. When restricted access is set, users who would
normally be disallowed from having channel operator privileges
(users with negative access levels and, if secure ops is
set, users not on the access list) will instead be kicked and
banned from the channel.
[Top]

SET SECURE
- Syntax:
- SET channel SECURE {ON | OFF}
Enables or disables ChanServ's security features for a
channel. When SECURE is
set, only users who have registered their nicknames with
NickServ and IDENTIFY'd with their password will be given access
to the channel as controlled by the access list.
[Top]

SET SECUREOPS
- Syntax:
- SET channel SECUREOPS {ON | OFF}
Enables or disables the secure ops option for a
channel. When secure ops is set, users who are not on the
userlist will not be allowed chanop status.
[Top]

SET LEAVEOPS
- Syntax:
- SET channel LEAVEOPS {ON | OFF}
Enables or disables the leave ops option for a
channel. When leave ops is set, ChanServ will never de-op
a user in that channel except with the DEOP
command.
[Top]

SET OPNOTICE
- Syntax:
- SET channel OPNOTICE {ON | OFF}
Enables or disables the op-notice option for a
channel. When op-notice is set, ChanServ will send a
notice to the channel whenever the OP
or DEOP commands are used for a
user in the channel.
[Top]

ACCESS
- Syntax:
- ACCESS channel ADD nick level
ACCESS channel DEL {nick | entry-num
| list}
ACCESS channel LIST [mask | list]
Maintains the access list for a channel. The access
list specifies which users are allowed chanop status or access
to ChanServ commands on the channel. Different user levels allow
for access to different subsets of privileges; /msg
ChanServ HELP ACCESS LEVELS for more specific
information. Any nick not on the access list has a user level of
0.
The ACCESS ADD command adds the given nickname to the
access list with the given user level; if the nick is already
present on the list, its access level is changed to the level
specified in the command. The level specified must be
less than that of the user giving the command, and if the nick
is already on the access list, the current access level of that
nick must be less than the access level of the user giving the
command.
The ACCESS DEL command removes the given nick from the
access list. If a list of entry numbers is given, those entries
are deleted. (See the example for LIST below.)
The ACCESS LIST command displays the access list. If a
wildcard mask is given, only those entries matching the mask are
displayed. If a list of entry numbers is given, only those
entries are shown; for example:
ACCESS #channel LIST 2-5,7-9 Lists access entries
numbered 2 through 5 and 7 through 9.
[Top]

ACCESS LEVELS
User access levels
By default, the following access levels are defined:
- Founder
- Full access to ChanServ functions; automatic opping upon
entering channel. Note that only one person may have founder
status (it cannot be given using the ACCESS
command).
- 10
- Access to AKICK command; automatic opping.
- 5
- Automatic opping.
- 3
- Automatic voicing.
- 0
- No special privileges; can be opped by other ops (unless secure-ops
is set). <0 May not be opped.
These levels may be changed, or new ones added, using the LEVELS
command; type /chanserv HELP LEVELS
for information.
[Top]

AKICK
- Syntax:
- AKICK channel ADD mask [reason]
AKICK channel DEL mask
AKICK channel LIST [mask]
Maintains the AutoKick list for a channel. If a user
on the AutoKick list attempts to join the channel, ChanServ will
ban that user from the channel, then kick the user.
The AKICK ADD command adds the given nick or usermask
to the AutoKick list. If a reason is given with the
command, that reason will be used when the user is kicked; if
not, the default reason is "You have been banned from the
channel".
The AKICK DEL command removes the given nick or mask
from the AutoKick list. It does not, however, remove any bans
placed by an AutoKick; those must be removed manually.
The AKICK LIST command displays the AutoKick list, or
optionally only those AutoKick entries which match the given
mask.
[Top]

LEVELS
- Syntax:
- LEVELS channel SET type level
LEVELS channel {DIS | DISABLE} type
LEVELS channel LIST
LEVELS channel RESET
The LEVELS command allows
fine control over the meaning of the numeric access levels used
for channels. With this command, you can define the access level
required for most of ChanServ's functions. (The SET
FOUNDER and SET PASSWORD
commands, as well as this command, are always restricted to the
channel founder.)
LEVELS SET allows the access level for a function or
group of functions to be changed. LEVELS DISABLE (or DIS
for short) disables an automatic feature or disallows access to
a function by anyone other than the channel founder. LEVELS
LIST shows the current levels for each function or group of
functions. LEVELS RESET resets the levels to the default
levels of a newly-created channel (see HELP
ACCESS LEVELS).
For a list of the features and functions whose levels can be
set, see HELP LEVELS DESC.

MemoServ is a utility allowing IRC users to send short
messages to other IRC users, whether they are online at the time
or not, or to channels(*). Both the sender's nickname and the
target nickname or channel must be registered in order to send a
memo.
MemoServ's commands include:
- SEND
- Send a memo to a nick or channel
- LIST
- List your memos
- READ
- Read a memo or memos
- DEL
- Delete a memo or memos
- SET
- Set options related to memos

with the NickServ LEVELS command.
[Top]

SEND
- Syntax:
- SEND {nick | channel} memo-text
Sends the named nick or channel a memo
containing memo-text. When sending to a nickname, the
recipient will receive a notice that he/she has a new memo. The
target nickname/channel must be registered.
[Top]

LIST
- Syntax:
- LIST [channel] [list | NEW]
Lists any memos you currently have. With NEW, lists
only new (unread) memos. Unread memos are marked with a
"*" to the left of the memo number. You can also
specify a list of numbers, as in the example below:

sends you the memo you most recently received. If NEW is given,
sends you all of your new memos. Otherwise, sends you memo
number num. You can also give a list of numbers, as in
this example:
READ 2-5,7-9 Displays memos numbered 2 through 5 and 7
through 9.
[Top]

DEL
- Syntax:
- DEL [channel] {num | list |
ALL}
Deletes the specified memo or memos. You can supply multiple
memo numbers or ranges of numbers instead of a single number, as
in the second example below.
If ALL is given, deletes all of your memos.
- Examples:
-
- DEL 1
- Deletes your first memo.
- DEL 2-5,7-9
- Deletes memos numbered 2 through 5 and 7 through 9.
