1 Numeric 005 Documentation 2 (c) 2002-2005 codemastr (Dominick Meglio) [codemastr@unrealircd.com] 3 (c) 2005-2009 syzop (Bram Matthys) [syzop@vulnscan.org] 4 5 Numeric 005 allows the server to inform the client of any protocol specific features in the 6 IRCd. The numeric is sent at connection time immediately after numeric 004. Additionally 7 the numeric is sent when a /version request is made by a local user, for remote users 8 numeric 105 is used but contains the same information. 9 10 Due to the limit imposed by RFC1459 on both the buffer size (512) and the amount of 11 parameters that can be sent in a single command (15) a total of 13 parameters may be 12 specified in each 005. Because of this, a client must be able to accept multiple 005s 13 consecutively. The format for the 005 message is as follows: 14 15 ":" <servername> "005" SPACE <nickname> SPACE <token[=value]> SPACE ... ":are supported 16 by this server" 17 18 Currently UnrealIRCd supports several tokens that are included in numeric 005. A list of 19 all tokens, their respective value and a brief description are listed below. 20 21 UnrealIRCd attempts to follow the proposed ISupport standard as much as possible. UnrealIRCd 22 only ignores the standard in one regard, the TARGMAX token. This token is believed to be 23 impractical and technically impossible to correctly implement due to existing limitations 24 in the standard. Therefore, this token is not currently supported. 25 26 UnrealIRCd does additionally provide a few tokens which are not specified in the standard, these 27 include: HCN, AWAYLEN, WATCH, SILENCE, EXTBAN, ELIST, CMDS, NAMESX, UHNAMES, and WATCHOPTS. 28 UnrealIRCd also maintains a few legacy tokens such as MAXCHANNELS and WALLCHOPS to ensure 29 compatibility until the ISupport standard is more widely accepted by clients. 30 31 Token Value Default Value Description 32 ------------------------------------------------------------------------------------------------ 33 MAP none none Informs the client that the /map 34 command is present. [Obsolete] 35 36 KNOCK none none Informs the client that the /knock 37 command is present. [Obsolete] 38 39 SAFELIST none none The LIST command is sent in 40 multiple iterations so that the 41 client's queue does not get filled 42 causing the user to be killed. 43 44 HCN none none The server supports the HCN 45 (Hybrid Connect Notice) protocol. 46 47 MAXCHANNELS number 10 The maximum number of channels a 48 user may join. [Deprecated] 49 50 MAXBANS number 60 The maximum number of bans that 51 may be placed for a channel. 52 [Obsolete] 53 54 NICKLEN number 30 Maximum length of a user's 55 nickname. 56 57 TOPICLEN number 307 Maximum length of a channel's 58 topic. 59 60 KICKLEN number 307 Maximum length of a kick reason. 61 62 MAXTARGETS number 20 Maximum targets for the PRIVMSG 63 command. 64 65 AWAYLEN number 307 Maximum length of an away message. 66 67 WALLCHOPS none none Indicates that you may use 68 NOTICE/PRIVMSG to send to +ohv by 69 using PRIVMSG/NOTICE [@|%|+]#channel. 70 [Deprecated] 71 72 WATCH number 128 Indicates the presence of the 73 WATCH command and specifies the 74 maximum number of watch entries. 75 76 SILENCE number 15 Indicates the maximum number of 77 entries on the silence list. 78 79 MODES number 13 Indicates the number of channel 80 modes with parameters that may be 81 sent at one time. 82 83 CHANTYPES chars # Indicates the prefixes available 84 for channels. 85 86 PREFIX (modes)prefixes (qaohv)~&@%+ Indicates the modes on a channel 87 that corespond to the given 88 nickname prefixes. 89 90 CHANMODES A,B,C,D be,kfL,lj, Specifies how each channel mode is 91 psmntirRcOAQKVHGCuzNSMT set/unset. The A section specifies 92 modes that add a nick/mask to a 93 list. The B section specifies 94 modes that require a parameter 95 to be both set and unset. The C 96 section specifies modes that 97 only require a parameter to be 98 set, and the D section 99 specifies modes that require no 100 parameters. 101 102 NETWORK string no default value Specifies the name of the 103 network that the server is 104 connected to. 105 106 CASEMAPPING string ascii Specifies what definition the 107 server uses when determining if 108 characters are upper/lowercase 109 of eachother. 110 111 EXTBAN prefix,types ~,cqnr Specifies what extbans are 112 supported by the server. The prefix 113 defines which character indicates 114 an extban and the types defines 115 which extbans the server supports. 116 117 ELIST flags MNUCT Specifies the set of extended LIST 118 options supported. The M flag 119 indicates mask based searching, 120 the N flag indicates negative 121 mask based searching. The U flag 122 means support for user count 123 searching. The C flag allows channel 124 creation time searching, and the T 125 flag allows topic set time 126 searching. 127 128 CMDS commands MAP,KNOCK,DCCALLOW,USERIP Specifies a series of commands that 129 can be useful for the client to know 130 exist as they may provide a more 131 efficient means for the client to 132 accomplish a specific task. This 133 token replaces the MAP and KNOCK 134 tokens. 135 136 STATUSMSG flags ~&@%+ Specifies the mode flags that may 137 prefix a channel name in a PRIVMSG 138 or NOTICE to limit who receives the 139 message to only those with a certain 140 level of access. This token will 141 replace the WALLCHOPS token. 142 143 EXCEPTS none none Indicates that channel ban exceptions 144 (+e) are supported by the server. 145 146 INVEX none none Indicates that channel invite 147 exceptions (+I) are supported by 148 the server. 149 150 MAXLIST mode:num,... b:60,e:60,I:60 Specifies the maximum number of 151 entries that may be added to a 152 particular mode list (type A modes). 153 This token replaces MAXBANS. 154 155 CHANLIMIT pfx:num,... #:10 Specifies the maximum number of 156 channels with the specified prefix 157 that a user may join at one time. 158 This token will replace MAXCHANNELS. 159 160 CHANNELLEN number 32 Provides the maximum length of a 161 channel name that a user can create. 162 163 NAMESX none none Indicates that extended /NAMES info 164 is available on this server. If the 165 client sends "PROTOCTL NAMESX" then 166 the server will, from then on, send 167 all channel rights in a NAMES reply 168 instead of only the highest right 169 (eg: @+Person instead of @Person). 170 171 UHNAMES none none Indicates that (other) extended 172 /NAMES info is available on the 173 server. If the client sends 174 "PROTOCTL UHNAMES" then the server 175 will, from then on, send user@host 176 information in a NAMES reply 177 (eg: @nick!ident@hostname). 178 179 WATCHOPTS flags A WATCH options supported. 'A' means 180 Away Notification is available.
