History - - draft v0.1 : 21.8.1999 - - Just a first draft of my botnet design I did on a boring friday - work afternoon :) I'll try to implement this to irssi some day, it - feels pretty interesting now so it might be pretty soon even. Any - comments are welcome :) - - draft v0.2 : 21.11.1999 - - Exactly three months since the first draft :) Now I actually have - some code done, just committed pretty simple botnet to irssi CVS. - Made several changes to this document.. Still missing much details - but the basic idea should be clear. - - draft v0.3 : 21.05.2000 - - Strange, again the same day. I really didn't plan this :) - Reformatted the text, added lots of text, implemented more of the - stuff. - - - 1. General - - 1.1 Description - - A small description of what botnet would do: A group of bots - efficiently working together to perform their tasks. Like when - someone's trying to take over your channel, bots will quickly - decide who deops/kicks whom instead of multiple bots deopping or - trying to kick the same people. - - Irssi's botnet is pretty much based on trust. Some malicious bot - can quite well mess up the whole botnet. Connecting the bots to - each other via ssh would be a good idea. - - 1.2 Configuration - - example config file: - - mybotnet = - { - priority=5; - nick=mybot; - uplinks = ( - { host = "main.botnet.org"; password = "mypass"; }, - { host = "alter.botnet.org"; password = "pass2"; } - ); - downlinks = ( - { password = "thepass"; valid_addrs = ( "192.168.0.*" ); }, - { password = "blah"; valid_addrs = ( "*.botnet.org" ); }, - { password = "localpass"; valid_addrs = ( "127.*" ); } - ); - } - - When connecting to botnet, the bot first tries to connect to the - first bot in uplinks list, then the second, etc. Setting port to -1 - will prevent connecting to the bot, 0 uses the default. - - 1.3 Botnet master - - To avoid total chaos inside botnet, the bots shouldn't do (almost) - anything without a command from botnet's master. The master should - know everything, and give commands to clients that can perform the - task best. - - Master is the bot with the highest priority. If there's multiple - with the same priority, the one that already was the master will - stay master. When joining two botnets to one, the uplink's master - stays. If link to master breaks, the closest bot to it will choose - a new one. - - The priorities should be given so that the bots that have the - fastest connections and are in the middle of the botnet have the - highest priorities. - - 1.4 Command format - - Commands that are sent inside botnet are in the following format: - - <from_nick> <to_nick> COMMAND [command specific data..] - - If to_nick is '-', the command should be sent to everyone. - - - 2. Handshake - - First host checks from bots' valid_addrs who is connecting. If - there's no matches it just disconnects the client. - - CLIENT: PASS <password> - HOST : (if error, disconnect) - - CLIENT: NICK <nick> - HOST : NICKERROR | CONNECTED - - If nick is already in use, the host sends NICKERROR and waits for - new nick. - - Now we're connected to botnet. The commands from now on use the - format specified in section 1.4. - - Both the client and the host sends information to other side of - all the clients they serve (if any): - - BOTINFO <nick> <connected_to_nick> <priority> - - BOTINFOs must be sent sorted so that connected_to_nick bot is - always known. Like first comes the bots connected to the - host/client, then the bots connected to them etc. - - If the client had downlinks, nick collisions might happen. The - uplink is responsible for noticing them from BOTINFO commands. - It should automatically replace the nicks with new ones and - send nick change command to client and all it's downlinks. For - example if host received: - - BOTINFO bot highbot 10 - - And the bot already exists, the BOTINFO is changed to: - - BOTINFO bot2 highbot 10 - - And the client and it's downlinks are notified: - - BOTNICK bot2 bot - - After sending BOTINFOs, the host tells the current master: - - MASTER <nick> - - The client now checks if it's priority is higher than the current - master's. If it is, it will send the MASTER command without any - parameters. - - - 3. Bot connections - - 3.1 General - - Everyone's connections should be kept in n-way tree. Example: - - - [highuplink] - _____________/ | | \ - / | [h5] [h6] - [h1] | / | \ - / \ | [h7] | [h8] - [h2] [h3] | | \ - | [uplink] [h9] [h10] - [h4] / | \ - [up2] | [up1] - / | | | - [up3] [up4] | [up5] - | - [we] - / \ - [client1] [client2] - / \ - [c3] [c4] - - - Botnet should try to keep together even if some hub in the middle - crashes. Each bot should have at least two uplinks in case one - dies. For example if [uplink] dies, [we] and [up1] could connect - to [up2], and [up2] could connect to [highuplink]. - - When connection is closed to some bot, a notice is sent by the - bot's uplink: - - BOTQUIT <nick> - - The quit notice should be sent only about the bot that was - disconnected. Bots should figure out themselves the other bots and - remove them too from their lists. - - 3.2 Lag - - Each bot should send PING commands to their up/downlinks every - now and then (1min?) to check that the connection is still active. - If the PONG isn't received in 10 seconds, it's priority should be - temporarily lowered to -1. If the PONG isn't received in 3 - minutes, the whole connection should be closed. - - Master should know lag times of every bots. It could then - automatically raise/lower bots' priorities depending on how big - their lag is. Master could also lower it's own priority and pass - the master status to someone else with lower lag. - - If there's lot of lag (>3sec?) somewhere and something urgent - happens, the botnet could split and behave independently. - - - 4. IRC networks - - 4.1 Server connections - - When bot is connected to some irc server and is ready to take - commands, it says: - - IRCJOIN <tag> <ircnet> <server> <nick> - - Tag is the bot specific unique tag of the server, so that the bot - can connect multiple times to same IRC network. All IRC related - commands should specify the server tag where it should be sent. - - If bot quits an irc network, it says: - - IRCQUIT <tag> - - 4.2 IRC commands - - Master asks a bot to send some command to IRC server by saying: - - CMD <id> <tag> <command> - - <command> can't really be anything, since the bot should also be - able to reply to it. The <id> is for identifying the command/reply - pair. Master should keep the command in memory until it receives - the reply: - - CMDREPLY <id> <last> <reply> - - The command could get a reply of multiple lines, so <last> - specifies if the reply is the last line (1 or 0). - - If the command failed for some reason, the bot will reply with - - CMDFAIL <id> - - and master should send the command to some other bot. - - 4.3 Channels - - When joined/left channels, the bot says: - - CHANJOIN <tag> <channel> - CHANPART <tag> <channel> - - After BOTJOIN, master tries to op the bot. When bot receives +o, - it says: - - CHANOP <tag> <channel> - - If it is the first opped bot in channel, master orders the bot to - op the rest of the bots. - - If the bot is kicked, it says: - - CHANKICK <tag> <channel> - - When master notices that bot is kicked, it first checks if there's - any other opped bots in channel. If not, it waits for a random - pause, 5-10sec before letting the bot join the channel again so - that it won't get autorejoin ban. - - If bot can't join channel, it says: - - CHANBANNED <tag> <channel> - (or) - CHANCANTJOIN <tag> <channel> - - When received BOTBANNED, master tries to unban bot or set a ban - exception. BOTCANTJOIN results as invite to channel. - - 4.4 Channel information - - When master notices that bot is the first one joined to channel, - it asks the bot for some channel information: - - CMD <id> <tag> NAMES <channel> - CMD <id> <tag> WHO <channel> - CMD <id> <tag> MODE <channel> - CMD <id> <tag> MODE b <channel> - CMD <id> <tag> MODE e <channel> (if IRC network supports this) - CMD <id> <tag> MODE I <channel> (if IRC network supports this) - - It's also possible that if several bots join immediately after the - first bot, the commands are shared between all the bots. - - Bots should cache the information as much as possible, at least - NAMES command. - - 4.5 Channel priorities - - Every channel has a priority: LOW, NORMAL, HIGH. - - Normally LOW operates just as NORMAL channels, except when some - channel has HIGH priority and bots are really busy, LOW channels - just wait until there's time for them. - - In NORMAL channels, the most urgent operations (kicks, ops, deops) - are performed quite soon even while bots are busy handling HIGH - priority commands. - - Channels shouldn't normally be HIGH priority, but if attack - against channel is detected (like someone comes from split, gets - ops and gets to op someone else), it's priority is set to HIGH. - When channel's priority is HIGH, botnet does everything it can to - get rid of unauthorized opped people as fast as possible. - - LOW channel's priority can also be raised to HIGH, but it's - priority is dropped back to LOW if some NORMAL channel's priority - is raised to HIGH too. - - Master notifies about channel's priority change by saying: - - CHANPRIORITY <ircnet> <channel> <LOW/NORMAL/HIGH> - diff --git a/src/irc/bot/Makefile.am b/src/irc/bot/Makefile.am deleted file mode 100644 index a97abf07..00000000 --- a/src/irc/bot/Makefile.am +++ /dev/null @@ -1,32 +0,0 @@ -moduledir = $(libdir)/irssi/modules -module_LTLIBRARIES = libirc_bot.la - -libirc_bot_la_LDFLAGS = -avoid-version - -INCLUDES = \ - -I$(top_srcdir)/src \ - -I$(top_srcdir)/src/core/ \ - -I$(top_srcdir)/src/irc/core/ \ - $(GLIB_CFLAGS) - -libirc_bot_la_LIBADD = -lcrypt - -libirc_bot_la_SOURCES = \ - bot.c \ - bot-irc-commands.c \ - bot-events.c \ - bot-users.c \ - botnet.c \ - botnet-connection.c \ - botnet-users.c - -noinst_HEADERS = \ - bot.h \ - bot-users.h \ - botnet.h \ - botnet-users.h \ - module.h - -EXTRA_DIST = \ - users.sample \ - botnets.sample diff --git a/src/irc/bot/bot-events.c b/src/irc/bot/bot-events.c deleted file mode 100644 index 9ef646de..00000000 --- a/src/irc/bot/bot-events.c +++ /dev/null @@ -1,201 +0,0 @@ -/* - bot-events.c : IRC bot plugin for irssi - - Copyright (C) 1999 Timo Sirainen - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
