I have the following in my /etc/hosts.deny file
#
# hosts.deny This file describes the names of the hosts which are
# *not* allowed to use the local INET services, as decided
# by the '/usr/sbin/tcpd' server.
#
# The portmap line is redundant, but it is left to remind you that
# the new secure portmap uses hosts.deny and hosts.allow. In particular
# you should know that NFS uses portmap!
ALL:ALL
and this in /etc/hosts.allow
#
# hosts.allow This file describes the names of the hosts which are
# allowed to use the local INET services, as decided
# by the '/usr/sbin/tcpd' server.
#
ALL:xx.xx.xx.xx , xx.xx.xxx.xx , xx.xx.xxx.xxx , xx.x.xxx.xxx , xx.xxx.xxx.xxx
but i am still getting lots of these emails:

whats worse is csf is trying to auto block these ip's when the attempt to get in but although it does put ip's in the csf.deny file they do not get blocked either
So i am trying to block all ip's with /etc/hosts.deny and allow only the ip's i use with /etc/hosts.allow but so far it doesn't seem to work.
right now i'm having to manually block each one with iptables, I would rather it automatically block the hackers in case I was away from a pc or asleep
