The big lie of computer security is that security improves by imposing complex passwords on users. In real life, people write down anything they can't remember. Security is increased by designing for the way humans actually behave. -Jakob Nielsen

rawr! raw IRC
Published by: weekend hacker, on 2007-08-10 22:30:20
Intro: IRC is a plaintext protocol. So all commands sent to and from the server are readable to humans. To create a bot or an irc client all you need to know is what commands to send and how to get information from the server. It can be chalenging for someone new to this to get a good list of these commands so thats basicly whats going to be in this article. I will first talk about stuff that gets send and then about stuff that your client/bot will get. In this litle article I will replace some characters that you can't see on this webpage with chr(x). When you see this then replace that with the char that has the valu of x (chr(97) would be a) If you ever did some programing then I bet you have seen that stuff before. (anything between < > should be replaced with other stuff, do NOT type the < and >) ---------------------------------------------------- Stuff to send: This part lists things a client/bot can send to the server. You can jump to a command here or simply scrolldown yourself: USER, NICK, PING/PONG, JOIN, PART, PRIVMSG, NOTICE,CTCP, ACTION, QUIT, ADMIN, AWAY, CREDITS, HELP, HELPOP, INFO, ISON, INVITE, KICK, KNOCK, LINKS, LIST, MODE, MOTD, RULES, SILENCE, STATS, TIME, TOPIC, USERHOST, VERSION, WATCH, WHO, WHOIS, WHOWAS USER (list)(top) This is the first thing your client/bot has to send to the irc server. Altough the rfc sais that NICK comes first lets just not listen to that and do this first. It should be in this format: CODE : `USER ident localhost localhost :name` When you whois a person using that to connect you will see person is ident@whatever.com * name (The name can be several words) NICK (list)(top) This should be send right after the user so the server knows what nick you are going to use. You can also always use it to change your nick: CODE : `NICK <newnick>` PING/PONG (list)(top) The most important thing any bot or client should respond to is PING. When the server sends you a ping it will send: CODE : `PING <random stuff>` Some servers might send their server name with the random stuff some might not.. If you are making a client/bot you should make it respond with: CODE : `PONG <the random stuff>` If your client/bot doesn't send the pong fast enough then the server will disconnect it. JOIN (list)(top) You can join any channel by sending: CODE : `JOIN <#channel>` Or you can join several channels at the same time by seperating them with a , CODE : `JOIN <#channel1,#channel2,#channel3>` Joining channel 0 will make you part all channels you are in. PART (list)(top) you can part a channel you are in (with a part message if you want): CODE : `PART <#channel> :<part message>` PRIVMSG (list)(top) This is used to send text to channels and other persons. You use it like this: CODE : `PRIVMSG <#channel or nick> :<message>` NOTICE (list)(top) You can notice others or intire channels with: CODE : `NOTICE <#channel or nick> :<message>` CTCP (list)(top) A ctcp is also basicly a privmsg that starts with chr(1) and ends with it. Example: CODE : `PRIVMSG <nick or <#channel> :chr(1)VERSIONchr(1)` That is the version request that requests the version of an other client. A ctcp responce is a notice that starts and ends with chr(1). A posible reply to the above example could be: CODE : `NOTICE <nick> :chr(1)mIRC v6.17 Khaled Mardam-Beychr(1)` ACTION (list)(top) An action is basicly a CTCP. A privmsg you start the message with chr(1)ACTION and end it with chr(1). CODE : `PRIVMSG <#channel or nick> :chr(1)ACTION likes puppieschr(1)` QUIT (list)(top) The proper way to quit the server is by sending it a quit signal with a message: CODE : `QUIT :<message>` The server will then disconnect you and show the message to anyone in the same channel as you. ADMIN (list)(top) Gives administrative info about the server you are on: CODE : `ADMIN` You can also get the info of an other server on the same network. CODE : `ADMIN <servername>` AWAY (list)(top) You can set yourself away so others who whois you can see you aren't around with: CODE : `AWAY :<away message>` You can turn it off by simply sending: CODE : `AWAY` CREDITS (list)(top) Shows the ircd credits (usualy a big ass list). CODE : `CREDITS` HELP (list)(top) Displays the ircd's help message CODE : `HELP` HELPOP (list)(top) Alows you to ask a specific question. The helpops on the server will get a message with your question. CODE : `HELPOP how do you work this irc thing` If you add a ? before your question then you can trigger some autoresponces. CODE : `HELPOP ?USERCMDS HELPOP ?OPERCMDS HELPOP ?SVSCMDS HELPOP ?UMODES HELPOP ?SNOMASKS HELPOP ?CHMODES HELPOP ?OFLAGS` INFO (list)(top) Shows the ircd info file of the server you are on or an other server on the network. CODE : `INFO <server name(optional)>` ISON (list)(top) Used to determine if a user is on irc or not. CODE : `ISON <nick>` INVITE (list)(top) If you have op or something higher you can invite others into the channel with this: CODE : `INVITE <nick> <#channel>` KICK (list)(top) If you have halfop or more you can kick some users out of the channel with: CODE : `KICK <#channel> <nick> :<kick message>` When combined with a ban the affected user can no longer join the channel. Without the ban its usually considered a warning. KNOCK (list)(top) You can knock on a channel to let ops know that you wanted to be invited. (if channel is +i you can only join when you are invited) CODE : `KNOCK <#channel>` LINKS (list)(top) Shows what servers are linked on the network. LIST (list)(top) List all channels and their info (topic, users etc) CODE : LIST (lists all channels) LIST >100 (lists all channels with 100 users or more) LIST <10 (lists all channels with 10 users or less) LIST C>15 (lists all channels created between now and 15 minutes ago) LIST C<30 (lists all channels created earlier than 30 minutes ago) LIST T>45 (list channels whose topics are older than 40 minutes) LIST T<60 (list channels whose topics are newer than 60 minutes) LIST moo (lists channels matching moo in their channel name) LIST !moo (lists all channels that do not match moo in their channel name) MODE (list)(top) Used for changing modes of a channel or person. CODE : `MODE <#channel or nick> <+modes-modes> <more info>` Settings mode +o (op) on a user in a channel is done like this: CODE : `MODE #channel +o user` For all modes see this article. MOTD (list)(top) Displays the Message Of The Day of the server you are on or one that is on the same network. CODE : `MOTD <server name(optional)>` RULES (list)(top) Shows the rules of the server or a server on the same network. CODE : `RULES <server name(optional)>` SILENCE (list)(top) Will ignore a user for as long as you are connected. CODE : `SILENCE <mask>` You can use use wildcards like with any other mask. Example: CODE : `SILENCE weekend!@.com` STATS (list)(top) Shows statistics on the server like a list of all the bans. CODE : `STATS` (to get a list of them all) CODE : `STATS Z` (to get info on send memory usage) Some info is only for opers. TIME (list)(top) Returns the TIME and date of a server. CODE : `TIME <server name(optional)>` TOPIC (list)(top) Shows the topic of a channel or can be used to change the topic if you have enough access to do so. CODE : `TOPIC <#channel> <new topic(optional)>` USERHOST (list)(top) Returns the hostname of a specific user. CODE : `USERHOST <nick>` VERSION (list)(top) Returns version info of the server you are on or one that is on the same network. CODE : `VERSION <server name(optional)>` WATCH (list)(top) Will make the server tell you when a specific user connects or disconnects untill you disconnect. CODE : `WATCH <+nick1> <+nick2> WATCH <-nick>` WHO (list)(top) Will list all visible ppl on the network. Use WHO +help to get more info. WHOIS (list)(top) Displays info of the user. CODE : `WHOIS <nick>` WHOWAS (list)(top) Gives info on a user that if that user has been connected recently. CODE : `WHOWAS <nick>` ---------------------------------------------------- Stuff your client will get: The first "word" your client gets is always the mask of the person who send it. If bob sends the message "I like pie" to the channel #moo then you will recieve: CODE : `:bob!bobsident@bobshost PRIVMSG #moo :I like pie` It will look just like the thing he send but with his host infront of it. This goes for almost all commands that don't list stuff. For any other thing it uses a number. Here is a big ass list of as many numbers I could find and their related command(if there is one) You can scroll down yourself or use this list to jump to a section Numbered list: 000 series, 200 series, 300 series, 400 series, 500 series, 600 series Topic list: ADMIN, AWAY, CNOTICE, CPRIVMSG, GLINE, HELPOP, INFO, INVITE, ISON, JOIN, KICK, KILL, LINKS, LIST, LUSERS, MAP, MODE, MOTD, NAMES, NICK, NOTICE, OPER, PART, PASS, PING, PRIVMSG, REHASH, SILENCE, STATS, SUMMON, TIME, TOPIC, USER, USERHOST, USERIP, USERS, VERSION, WATCH, WHO, WHOIS, WHOWAS 000 series (list)(top) 001 :Welcome to the Internet Relay Network nickname 002 :Your host is server, running version ver 003 :This server was created datetime 004 server ver usermode chanmode 005 :map 007 :End of /MAP 008 num :: Server notice mask (hex) 200 series (list)(top) 211 connection sendq sentmsg sentbyte recdmsg recdbyte :open 212 command uses bytes 213 C address * server port class 214 N address * server port class 215 I ipmask * hostmask port class 216 k address * username details 217 P port ?? ?? 218 Y class ping freq maxconnect sendq 219 char :End of /STATS report 221 mode 222 mask :comment 223 E hostmask * username ?? ?? 224 D ipmask * username ?? ?? 241 L address * server ?? ?? 242 :Server Up num days, time 243 o mask password user ?? class 244 H address * server ?? ?? 247 G address timestamp :reason 248 U host * ?? ?? ?? 249 :info 250 :Highest connection count: total (num clients) 251 :There are user users and invis invisible on serv servers 252 num :operator(s) online 253 num :unknown connection(s) 254 num :channels formed 255 :I have user clients and serv servers 256 :Administrative info about server 257 :info 258 :info 259 :info 263 :Server load is temporarily too heavy.
