# $1 IP of host which is under attack (incoming attack) or source of attack (outgoing attack)
# $2 Attack direction: incoming or outgoing
# $3 Attack bandwidth in packets per second
# $4 Attack action: ban or unban
#

# Please do not remove "cat" command because
# FastNetMon will crash in this case as it expects read of data from script side
