how do i deny an IP in my iptalbes? for example, let's say i want to deny IP 10.1.1.1 ? i am getting known hacks from certain IP's and I want to deny them?
last line in my iptables config file.
Code:
-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
COMMIT
Caveat with using tcp_wrappers (hosts.allow/deny) is that it only works for daemons that have support for libwrap. Not all do (Apache, Postfix and others do not) so make sure to check the docs to verify whether hosts.deny can do what you want.
