blocking input from certain IPaddresses
I run a mini-webserver on 192.168.1.80:80 behind a Linksys router.
This series didn't explain how I can block certain IPaddresses that
abuse that server. I ran 'sudo /sbin/iptables -L' and couldn't figure
out the mess. I use ufw under Kubuntu, but it doesn't allow a table-based
configuration, which is a PITA because the order of these rules is
important. Is there a simple line I can add to this script that would
block incoming access from a certain IPaddress?
Hardly "Mastering"
This series would be MUCH more appropriately named "an intro to IPTABLES"
