# sentinel.tcl v2.70 (15 April 2002)
# Copyright 1998-2002 by slennox
# slennox's eggdrop page - http://www.egghelp.org/
# Flood protection system for eggdrop, with integrated BitchX CTCP
# simulation. This script is designed to provide strong protection for your
# bot and channels against large floodnets and proxy floods.
#
# Note that this script was developed on the eggdrop 1.3, 1.4, and 1.6
# series and may not work properly on other versions.
#
# v2.00 - New standalone release. Contains refinements and features from
# the netbots.tcl version of sentinel.tcl.
# v2.50 - Locktimes of less than 30 were erroneously allowed.
# putquick -next is now supported (eggdrop 1.5+) for faster channel
# lock.
# - Ban mechanism now checks if flooders are coming from the same
# domain or ident and performs wildcard bans instead of banning
# each IP/host individually.
# - Added tsunami detection to the avalanche flood detection system.
# - Variables are now cleared after removing a channel.
# - Removed unnecessary botonchan checks throughout components where
# botisop already checks for that.
# - Removed all unnecessary use of parentheses.
# v2.60 - Modified putquick compatibility proc.
# - Added sl_wideban option to make domain/ident bans optional.
# - Fixed typos in various ban-related functions.
# - Unused procs are now unloaded.
# - Wildcard bans covering domains/idents were not doing proper
# checks on join-part flooders.
# v2.70 - Fixed "allbans" error which could occur when sl_wideban is
# disabled.
# - Added sl_masktype option, currently offering three different
# ban/ignore mask types.
# - Merged unsets in sl_unsetarray.
# - Changed use of "split" in timers to the less ugly "list".
#
# sentinel.tcl is centered around its channel lock mechanism. It sets the
# channel +mi (moderated and invite-only) whenever a substantial flood on
# the channel is detected. This ensures channel stability when flooded,
# allowing the bots to deal with the flood as smoothly as possible.
# sentinel.tcl detects the following types of floods:
#
# * Channel CTCP floods. This is the most common type of flood, and will
# often make users quit from the channel with 'Excess Flood'. A quick
# channel lock can prevent this.
# * Channel join-part floods. A common type of channel flood in which many
# floodbots cycle the channel.
# * Channel nick floods. Nick floods are unique in that they can occur even
# after a channel is locked. sentinel has special mechanisms to deal with
# this as effectively as possible.
# * Channel avalanche/tsunami floods. While the avalanche flood is quite
# uncommon these days, tsunami floods are often used to seriously lag
# mIRC and other clients using control codes (colour, bold, underline,
# etc.)
# * Channel text floods. Not small text floods - but when hundreds of
# messages are sent to the channel within a short period. Detected to
# stop really aggressive text floods and reduce the possibility of the
# bot crashing or consuming excessive CPU.
#
# sentinel also has additional protection features for the bot and channel:
#
# * Bogus username detection. Users with annoying bogus characters in their
# ident are banned. A channel lock is applied if multiple join in a short
# period.
# * Full ban list detection. During a serious flood, the ban list may
# become full. If this happens, the bots may start kick flooding since
# they cannot ban. If the ban list is full, the channel will be set +i.
# * Bot CTCP flood protection. Protects the bot if it is CTCP flooded.
# * Bot MSG flood protection. Protects the bot if it's flooded with MSGs or
# MSG commands.
# * Automatic bans and ignores. During a flood, sentinel will compile a
# list of the flooders, then kick-ban them after the channel has been
# locked.
# * BitchX simulation. This has been built-in mainly because you cannot use
# a third-party BitchX simulator with sentinel (only one script at a time
# can have control of CTCPs). sentinel provides accurate simulation of
# BitchX 75p1+ and 75p3+ CTCP replies and AWAY mode.
# * Public commands (lc and uc) and DCC commands (.lock and .unlock) for
# locking/unlocking channels.
# * DCC command .sentinel displays current settings.
#
# Important Notes:
# - Make sure no bots are enforcing channel mode -i and/or -m.
# - Bans are added to the bot's internal ban list, and expire after 24
# hours by default. If you have +dynamicbans set, the bans may be removed
# from the channel much sooner than this, but the ban will remain in the
# bot's internal ban list until it expires.
# - For greater protection against large channel floods, I recommend you
# also use a channel limiter script, such as chanlimit.tcl.
# - There is a trade-off between convenience and security. The more
# automation you enable, the more stress the bot will be under during a
# flood and the more stuff it will be sending to the server.
# - Where security is paramount, have one or two bots that aren't running
# sentinel.tcl. Since sentinel.tcl is a complex script with many
# automated and convenience features, there is a potential for
# vulnerabilities.
# The following flood settings are in number:seconds format, 0:0 to
# disable.
# Bot CTCP flood.
set sl_bcflood 5:30
# Bot MSG flood.
set sl_bmflood 6:20
# Channel CTCP flood.
set sl_ccflood 5:20
# Channel avalanche/tsunami flood.
set sl_avflood 6:20
# Channel text flood.
set sl_txflood 80:30
# Channel bogus username join flood.
set sl_boflood 4:20
# Channel join-part flood.
set sl_jflood 6:20
# Channel nick flood.
set sl_nkflood 6:20
# Flood setting notes:
# - Don't fiddle too much with the seconds field in the flood settings, as
# it can reduce the effectiveness of the script. The seconds field should
# set in the 20-60 seconds range.
# - Avalanche/tsunmami flood detection may be CPU intensive on a busy
# channel, although I don't think it's a big deal on most systems. If
# you're concerned about CPU usage you may wish to disable it, perhaps
# leaving it enabled on one bot. Disabling text flood protection can
# further reduce CPU usage.
# - On bots with avalanche/tsunami flood detection enabled, it's
# recommended that you also enable text flood detection to cap CPU usage
# during a flood.
# - If you enable nick flood detection, it's strongly recommended that it
# be enabled on all bots that have sentinel.tcl loaded. This is required
# for effective nick flood handling.
# Specify the number of control characters that must be in a line before
# it's counted by the tsunami flood detector. For efficiency reasons,
# tsunami detection is implemented with avalanche detection, so sl_avflood
# must be enabled for tsunami detection to be active. Setting this to 0
# will disable tsunami detection.
set sl_tsunami 10
# Valid settings: 0 to disable, otherwise 1 or higher.
# Length of time in minutes to ban channel flooders. This makes the bot
# perform kicks and bans on flooders after the channel lock. Because of the
# reactive nature of automatic bans, you should disable this on at least
# one bot for the most effective protection.
set sl_ban 1440
# Valid settings: 0 to disable, otherwise 1 or higher.
# Length of time in minutes of on-join bans for bogus usernames. For the
# most effective protection, you should disable this on at least one bot.
set sl_boban 1440
# Valid settings: 0 to disable, otherwise 1 or higher.
# Set global bans on channel flooders and bogus usernames?
set sl_globalban 0
# Valid settings: 1 for global bans, 0 for channel-specific bans.
# When processing a list of flooders, sentinel.tcl compares the hosts to
# see if multiple flooders are coming from a particular domain/IP or using
# the same ident (e.g. different vhosts on a single user account). If
# multiple flooders come from the same domain/IP, or if multiple flooders
# have the same ident, then the whole domain/IP (i.e. *!*@*.domain.com or
# *!*@555.555.555.*) or ident (i.e. *!*username@*) is banned. If you
# disable this option, all bans will be in *!*@machine.domain.com and
# *!*@555.555.555.555 format.
set sl_wideban 1
# Valid settings: 1 to enable, 0 to disable.
# Maximum number of bans allowed in the bot's ban list before sentinel will
# stop adding new bans. This prevents the bot from adding hundreds of bans
# on really large floods. Note that this has nothing to do with the channel
# ban list.
set sl_banmax 100
# Valid settings: 1 or higher.
# Length of time in minutes to ignore bot flooders. On bots with sl_ban
# active, channel flooders are also added to the ignore list.
set sl_igtime 240
# Valid settings: 1 or higher.
# Select the type of hostmask to use when banning and/or ignoring flooders.
# There are three to choose from:
# 0 - *!*@machine.domain.com / *!*@555.555.555.555
# 1 - *!*ident@machine.domain.com / *!*ident@555.555.555.555
# 2 - *!*ident@*.domain.com / *!*ident@555.555.555.*
# The default option, 0, is strongly recommended for most situations, and
# provides the best level of protection. The other two options are provided
# mainly for special cases.
set sl_masktype 0
# Valid settings: 0, 1, or 2, depending on the hostmask type you wish to use.
# Length of time in seconds to set channel +i if flooded. If set to 0, +i
# will not be removed automatically.
set sl_ilocktime 120
# Valid settings: 0 to prevent +i being removed automatically, otherwise 30
# or higher.
# Length of time in seconds to set channel +m if flooded. If set to 0, +m
# will not be removed automatically.
set sl_mlocktime 60
# Valid settings: 0 to prevent +m being removed automatically, otherwise 30
# or higher.
# On small floods (two flooders or less), remove the +mi shortly after bans
# have been set, instead of waiting for the locktimes to expire? This
# prevents unnecessary extended locks on small floods. This setting is only
# used by bots with sl_ban enabled.
set sl_shortlock 0
# Valid settings: 0 to disable, 1 to enable.
# Number of bans to allow in the channel ban list before setting the
# channel +i. If enabled, this should preferably be set to just below the
# maximum number of bans allowed.
set sl_bfmaxbans 19
# Valid settings: 0 to disable +i on full ban list, otherwise 1 or higher.
# List of users to send a note to when channel is flooded, bot is flooded,
# or ban list becomes full.
set sl_note "YourNick"
# Valid settings: one user like "Tom", a list of users like
# "Tom Dick Harry", or "" to specify that no notes are sent.
# Notice to send to channel when locked due to flood.
set sl_cfnotice "Channel locked temporarily due to flood, sorry for any inconvenience this may cause :-)"
# Valid settings: a text string, or set it to "" to disable.
# Notice to send to channel when locked due to full ban list.
set sl_bfnotice "Channel locked temporarily due to full ban list, sorry for any inconvenience this may cause :-)"
# Valid settings: a text string, or set it to "" to disable.
# Enable 'lc' and 'uc' public commands for locking/unlocking channel?
set sl_lockcmds 2
# Valid settings: 0 to disable, 1 to enable, 2 to require user to be opped
# on the channel to use the command.
# Users with these flags are allowed to use lc/uc public commands, and
# .lock/.unlock DCC commands.
set sl_lockflags "o"
# Valid settings: one flag like "n", or a list of flags like "fo" (means
# 'f OR o').
# Enable BitchX CTCP and AWAY simulation?
set sl_bxsimul 0
# Valid settings: 1 to enable, 0 to disable.
