Page 48

not been configured to allow connections from the
client's host as an operator, this error must be

- Reply format used by USERHOST to list replies to
the query list. The reply string is composed as
follows:

sent by the server to which the client is connected.
Replies RPL_UNAWAY and RPL_NOWAWAY are sent when the
client removes and sets an AWAY message.
311 RPL_WHOISUSER
"<nick> <user> <host> * :<real name>"
312 RPL_WHOISSERVER
"<nick> <server> :<server info>"

319 RPL_WHOISCHANNELS
"<nick> :{[@|+]<channel><space>}"
- Replies 311 - 313, 317 - 319 are all replies
generated in response to a WHOIS message. Given that
there are enough parameters present, the answering
server must either formulate a reply out of the above
numerics (if the query nick is found) or return an
error reply. The '*' in RPL_WHOISUSER is there as
the literal character and not as a wild card. For
each reply set, only RPL_WHOISCHANNELS may appear
more than once (for long lists of channel names).
The '@' and '+' characters next to the channel name
indicate whether a client is a channel operator or
has been granted permission to speak on a moderated
channel. The RPL_ENDOFWHOIS reply is used to mark
the end of processing a WHOIS message.
314 RPL_WHOWASUSER
"<nick> <user> <host> * :<real name>"
369 RPL_ENDOFWHOWAS

the replies RPL_WHOWASUSER, RPL_WHOISSERVER or
ERR_WASNOSUCHNICK for each nickname in the presented
--------------------------------------------------------------------------------
Page 50
list. At the end of all reply batches, there must be RPL_ENDOFWHOWAS (even if there was only one reply and it was an error).
321 RPL_LISTSTART
"Channel :Users Name"
322 RPL_LIST
"<channel> <# visible> :<topic>"
323 RPL_LISTEND
":End of /LIST"
- Replies RPL_LISTSTART, RPL_LIST, RPL_LISTEND mark
the start, actual replies with data and end of the
server's response to a LIST command. If there are
no channels available to return, only the start
and end reply must be sent.
324 RPL_CHANNELMODEIS
"<channel> <mode> <mode params>"
331 RPL_NOTOPIC
"<channel> :No topic is set"
332 RPL_TOPIC
"<channel> :<topic>"
- When sending a TOPIC message to determine the
channel topic, one of two replies is sent. If
the topic is set, RPL_TOPIC is sent back else
RPL_NOTOPIC.
341 RPL_INVITING
"<channel> <nick>"
- Returned by the server to indicate that the
attempted INVITE message was successful and is
being passed onto the end client.
342 RPL_SUMMONING
"<user> :Summoning user to IRC"
- Returned by a server answering a SUMMON message to
indicate that it is summoning that user.
351 RPL_VERSION
"<version>.<debuglevel> <server> :<comments>"
- Reply by the server showing its version details.
The <version> is the version of the software being
--------------------------------------------------------------------------------
Page 51
used (including any patchlevel revisions) and the
<debuglevel> is used to indicate if the server is
running in "debug mode".
The "comments" field may contain any comments about the version or further version details.
352 RPL_WHOREPLY
"<channel> <user> <host> <server> <nick> \
<H|G>[*][@|+] :<hopcount> <real name>"
315 RPL_ENDOFWHO
"<name> :End of /WHO list"
- The RPL_WHOREPLY and RPL_ENDOFWHO pair are used
to answer a WHO message. The RPL_WHOREPLY is only
sent if there is an appropriate match to the WHO
query. If there is a list of parameters supplied
with a WHO message, a RPL_ENDOFWHO must be sent
after processing each list item with <name> being
the item.
353 RPL_NAMREPLY
"<channel> :[[@|+]<nick> [[@|+]<nick> [...]]]"
366 RPL_ENDOFNAMES
"<channel> :End of /NAMES list"
- To reply to a NAMES message, a reply pair consisting
of RPL_NAMREPLY and RPL_ENDOFNAMES is sent by the
server back to the client. If there is no channel
found as in the query, then only RPL_ENDOFNAMES is
returned. The exception to this is when a NAMES
message is sent with no parameters and all visible
channels and contents are sent back in a series of
RPL_NAMEREPLY messages with a RPL_ENDOFNAMES to mark
the end.
364 RPL_LINKS
"<mask> <server> :<hopcount> <server info>"
365 RPL_ENDOFLINKS
"<mask> :End of /LINKS list"

end of the list using an RPL_ENDOFLINKS reply.
367 RPL_BANLIST
"<channel> <banid>"
368 RPL_ENDOFBANLIST
--------------------------------------------------------------------------------
Page 52
"<channel> :End of channel ban list"
- When listing the active 'bans' for a given channel,
a server is required to send the list back using the
RPL_BANLIST and RPL_ENDOFBANLIST messages. A separate
RPL_BANLIST is sent for each active banid. After the
banids have been listed (or if none present) a
RPL_ENDOFBANLIST must be sent.
371 RPL_INFO
":<string>"
374 RPL_ENDOFINFO
":End of /INFO list"
- A server responding to an INFO message is required to
send all its 'info' in a series of RPL_INFO messages
with a RPL_ENDOFINFO reply to indicate the end of the
replies.
375 RPL_MOTDSTART
":- <server> Message of the day - "
376 RPL_ENDOFMOTD
":End of /MOTD command"
- When responding to the MOTD message and the MOTD file
is found, the file is displayed line by line, with
each line no longer than 80 characters, using
RPL_MOTD format replies. These should be surrounded
by a RPL_MOTDSTART (before the RPL_MOTDs) and an
RPL_ENDOFMOTD (after).
381 RPL_YOUREOPER
":You are now an IRC operator"
- RPL_YOUREOPER is sent back to a client which has
just successfully issued an OPER message and gained
operator status.
382 RPL_REHASHING

- If the REHASH option is used and an operator sends
a REHASH message, an RPL_REHASHING is sent back to
the operator.
391 RPL_TIME
--------------------------------------------------------------------------------
Page 53
"<server> :<string showing server's local time>"
- When replying to the TIME message, a server must send
the reply using the RPL_TIME format above. The string
showing the time need only contain the correct day and
time there. There is no further requirement for the
time string.
392 RPL_USERSSTART
":UserID Terminal Host"
393 RPL_USERS
":%-8s %-9s %-8s"

replies RPL_USERSTART, RPL_USERS, RPL_ENDOFUSERS and
RPL_NOUSERS are used. RPL_USERSSTART must be sent
first, following by either a sequence of RPL_USERS
or a single RPL_NOUSER. Following this is
RPL_ENDOFUSERS.

- The RPL_TRACE* are all returned by the server in
response to the TRACE message. How many are
returned is dependent on the the TRACE message and

whether it was sent by an operator or not. There is no predefined order for which occurs first. Replies RPL_TRACEUNKNOWN, RPL_TRACECONNECTING and RPL_TRACEHANDSHAKE are all used for connections which have not been fully established and are either unknown, still attempting to connect or in the process of completing the 'server handshake'. RPL_TRACELINK is sent by any server which handles a TRACE message and has to pass it on to another server. The list of RPL_TRACELINKs sent in response to a TRACE command traversing the IRC network should reflect the actual connectivity of the servers themselves along that path.
RPL_TRACENEWTYPE is to be used for any connection which does not fit in the other categories but is being displayed anyway.

- To answer a query about a client's own mode,
RPL_UMODEIS is sent back.
251 RPL_LUSERCLIENT
":There are <integer> users and <integer> \

"<integer> :unknown connection(s)"
254 RPL_LUSERCHANNELS
"<integer> :channels formed"
255 RPL_LUSERME
":I have <integer> clients and <integer> \
servers"
- In processing an LUSERS message, the server
sends a set of replies from RPL_LUSERCLIENT,
RPL_LUSEROP, RPL_USERUNKNOWN,
RPL_LUSERCHANNELS and RPL_LUSERME. When
replying, a server must send back
RPL_LUSERCLIENT and RPL_LUSERME. The other
replies are only sent back if a non-zero count
is found for them.
256 RPL_ADMINME
"<server> :Administrative info"
257 RPL_ADMINLOC1
":<admin info>"
258 RPL_ADMINLOC2
":<admin info>"
259 RPL_ADMINEMAIL
":<admin info>"
- When replying to an ADMIN message, a server
is expected to use replies RLP_ADMINME
through to RPL_ADMINEMAIL and provide a text
message with each. For RPL_ADMINLOC1 a
description of what city, state and country
the server is in is expected, followed by
details of the university and department
(RPL_ADMINLOC2) and finally the administrative
contact for the server (an email address here
is required) in RPL_ADMINEMAIL.
