Changed configure.in's functionality so that you could tell what modules you
want to build in main irssi binary and it will create automatically the .c
files that need to call the module_init()/deinit() functions.

Fixed several minor things..

------ 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 A small description of what botnet would do: A group of bots
efficiently working together to perform their tasks. Like when efficiently working together to perform their tasks. Like when
someone's trying to take over your channel, bots will quickly decide someone's trying to take over your channel, bots will quickly

kick the same people.. trying to kick the same people.
config file: 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 = mybotnet =
{ {
priority=n; priority=5;
nick=mybot; nick=mybot;
bots= uplinks = (
( { host = "main.botnet.org"; password = "mypass"; },
{ host="another.org"; port=5567; password="blah"; { host = "alter.botnet.org"; password = "pass2"; }
valid_addrs=("*.another.org"); }, );
{ host="blah.ircnetthing.net"; password="blah"; downlinks = (
valid_addrs=("*.ircnetthing.net", "*.blah.org"); }, { password = "thepass"; valid_addrs = ( "192.168.0.*" ); },
{ host="some.thing.net"; password="blah"; { password = "blah"; valid_addrs = ( "*.botnet.org" ); },
valid_addrs=("some.thing.net"); } { password = "localpass"; valid_addrs = ( "127.*" ); }
); );
} }
When connecting to botnet, it first tries to connect to the first bot When connecting to botnet, the bot first tries to connect to the
in bots list, then the second, etc. Setting port to 0 will prevent first bot in uplinks list, then the second, etc. Setting port to -1
connecting to the bot. will prevent connecting to the bot, 0 uses the default.
Login: 1.3 Botnet master
First host checks what client is connecting from bots' valid_addrs. If 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. there's no matches it just disconnects the client.
CLIENT: PASS blah CLIENT: PASS <password>
HOST : (if error, disconnect) HOST : (if error, disconnect)
CLIENT: NICK nick
HOST : (if nick already in use) NICKERROR
CLIENT: PRIORITY=n
HOST : MASTER nick
HOST : CONNECTED
Then host sends a list of all connected bots in botnet: CLIENT: NICK <nick>
BOTINFO nick connected-to-nick address priority HOST : NICKERROR | CONNECTED
Now we're connected to botnet, rest of the commands will be send to If nick is already in use, the host sends NICKERROR and waits for
everyone. Commands are the following format (I won't write the nick new nick.
from now on):
nick COMMAND [command specific data..] Now we're connected to botnet. The commands from now on use the
format specified in section 1.4.
After connection is established with the client, host sends (except to Both the client and the host sends information to other side of
the connected client): all the clients they serve (if any):
BOTNEW client_nick client_address client_priority
Master is the client with the highest priority, if there's multiple BOTINFO <nick> <connected_to_nick> <priority>
with the same priority, the one who's nick is the first in alphabet
"wins" and says:
MASTER 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.
Also after connecting, client could check if it's priority is bigger than If the client had downlinks, nick collisions might happen. The
current master's and make itself the master. 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:
Bots should every now and then check if their connections are active by BOTINFO bot highbot 10
sending PING, the other side replies with PONG. If PONG isn't received
for a while (3 min?), the connection should be closed. If there's more
bots behind the lost bot, either side should try to reconnect to the
other one. Also if there's too much lag (>30sec) for some bots, their
priority could be temporarily lowered. When something urgent happens
and there's a lot of lag, each subset of bots should try to behave
independently.
When connection is closed to some bot, a notice is sent: And the bot already exists, the BOTINFO is changed to:
BOTQUIT nick
After bot is (dis)connected to some irc network and is ready to take BOTINFO bot2 highbot 10
commands, it sends notice:
BOTCONNECT ircnet (where ircnet is network's name, like IRCNet, EFNet, ..)
BOTDISCONNECT ircnet
After joining/leaving channels, bot sends notice: And the client and it's downlinks are notified:
BOTJOIN ircnet #channel
BOTPART ircnet #channel
After BOTJOIN, master tries to op the bot. When bot receives +o, it replies: BOTNICK bot2 bot
BOTOP ircnet #channel
If it's the first opped bot in channel, master orders the bot to op the rest After sending BOTINFOs, the host tells the current master:
of the bots.
Or after kicked or when being unable to join..: MASTER <nick>
BOTKICK ircnet #channel
BOTBANNED ircnet #channel
BOTCANTJOIN ircnet #channel
When master notices that bot is kicked, it first checks if there's any other The client now checks if it's priority is higher than the current
opped bots in channel. If not, it waits for a random pause, 5-10sec before master's. If it is, it will send the MASTER command without any
joining (so it won't get autorejoin ban). When received BOTBANNED, master parameters.
tries to unban bot, BOTCANTJOIN results as invite to channel.
When master notices that bot is the first one joined to channel, it asks bot
for channel information:
BOTCMD nick ircnet NAMES #channel 3. Bot connections
BOTCMD nick ircnet WHO #channel
BOTCMD nick ircnet MODE #channel
BOTCMD nick ircnet MODE b #channel
BOTCMD nick ircnet MODE e #channel
BOTCMD nick ircnet MODE I #channel
Next command is sent right after getting answer from the last query. It's also 3.1 General
possible that if several bots join immediately after the first bot, the
commands are shared between all the bots. After getting the results, the bot
replies:
BOTREPLY ircnet <reply> Everyone's connections should be kept in n-way tree. Example:
Bots should cache the information as much as possible, at least NAMES command.
[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. Every channel has a priority: LOW, NORMAL, HIGH.
Normally LOW operates just as NORMAL channels, except when some channel Normally LOW operates just as NORMAL channels, except when some
has HIGH priority and bots are really busy, LOW channels just wait channel has HIGH priority and bots are really busy, LOW channels
until there's time for them. just wait until there's time for them.
In NORMAL channels, the most urgent operations (kicks, ops, deops) are In NORMAL channels, the most urgent operations (kicks, ops, deops)
performed quite soon even while bots are busy handling HIGH priority are performed quite soon even while bots are busy handling HIGH
commands. priority commands.
Channels shouldn't normally be HIGH priority, but if attack against Channels shouldn't normally be HIGH priority, but if attack
channel is detected (like someone comes from split, gets ops and gets against channel is detected (like someone comes from split, gets
to op someone else), it's priority is set to HIGH. When channel's ops and gets to op someone else), it's priority is set to HIGH.
priority is HIGH, botnet does everything it can to get rid of When channel's priority is HIGH, botnet does everything it can to
unauthorized opped people as fast as possible. 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 LOW channel's priority can also be raised to HIGH, but it's
dropped back to LOW if some NORMAL channel's priority is raised to HIGH priority is dropped back to LOW if some NORMAL channel's priority
too. is raised to HIGH too.
Channel's priority can also be set manually: Master notifies about channel's priority change by saying:
CHPRIORITY ircnet #channel <LOW/NORMAL/HIGH>
------ CHANPRIORITY <ircnet> <channel> <LOW/NORMAL/HIGH>
