to use the auto kill on clones look in the config file: ( this is in the OperServ Configeration.
# ...Expiry <time> [REQUIRED]
# Sets the default expiry time for, respectively, AKILLs, SGLINEs,
# SQLINEs and SZLINEs.
AutoKillExpiry 30d
ChanKillExpiry 30d
SGLineExpiry 30d
SQLineExpiry 30d
SZLineExpiry 30d
# LimitSessions [OPTIONAL]
# Enables session limiting. Session limiting prevents users from
# connecting more than a certain number of times from the same host at the
# same time - thus preventing most types of cloning. Once a host reaches
# it's session limit, all clients attempting to connect from that host
# will be killed. Exceptions to the default session limit, which are based
# on host names, can be defined via the exception list. It should be noted
# that session limiting, along with a large exception list, can degrade
# services' performance. See the source and comments in sessions.c and the
# online help for more information about session limiting.
#
# NOTE: This option is not available when STREAMLINED is defined in
# the Makefile.
LimitSessions
# DefSessionLimit <limit> [REQUIRED]
# Default session limit per host. Once a host reaches it's session limit,
# all clients attempting to connect from that host will be killed. A value
# of zero means an unlimited session limit.
DefSessionLimit 5
# MaxSessionLimit <limit> [REQUIRED]
# The maximum session limit that may be set for a host in an exception.
MaxSessionLimit 100
# ExceptionExpiry <time> [REQUIRED]
# Sets the default expiry time for exceptions.
ExceptionExpiry 1d
# SessionLimitExceeded <message> [OPTIONAL]
# The message that will be NOTICE'd to a user just before they are removed
# from the network because their's host session-limit has been exceeded.
# It may be used to give a slightly more descriptive reason for the
# impending kill as apposed to simply "Session limit exceeded". If this is
# commented out, nothing will be sent.
SessionLimitExceeded "The session limit for your host %s has been exceeded."
