When logged in as root ( "su -" ), type:
cd /usr/bin
wget
http://www.geocities.com/steve93138/kiss-2.0.1.tar.gz
tar zxvf kiss-2.0.1.tar.gz
That's it! To get it running anywhere on the command line, you simply type:
kiss start
To stop the firewall, type:
kiss stop
To get status information, type:
kiss status
If you want to block an offenders IP address/subnet, simply edit the BLOCK_LIST variable in the /usr/bin/kiss file. You can separate IP addresses and subnet's with a space. Once you are finished, simply restart KISS by typing:
kiss restart
Last, but not least, it is recommended that you configure the firewall to allow only for needed ports. Using trusted IP addresses/subnets is also recommended. These variables are located near the beginning of the /usr/bin/kiss file and are self-explanatory. Once you make changes, you should always restart KISS for the changes to take effect:
kiss restart
