Getting KISS My Firewall to Work on Fedora Core

KISS My Firewall is an excellent firewall script for iptables. Unfortunately, it does not work out of the box on later versions of Fedora Core. Trying to run it, you’ll get the following error message:


Since the ip_tables, ipt_state, and/or ipt_multiport modules do not exist, KISS can not function. Firewall script aborted!

The reason for the message is that the files ip_tables.ko, ipt_state.ko and ipt_multiport.ko do not exist on Fedora, even if iptables is installed and working. The fix is simple. Go to line 140 in your kiss script file and comment out the following lines by adding a # hash character in front of them:


if [ ! -e "/lib/modules/$(uname -r)/kernel/net/ipv4/netfilter/ip_tables.$EXTN" ] || [ ! -e "/lib/modules/$(uname -r)/kernel/net/ipv4/netfilter/ipt_state.$EXTN" ] || [ ! -e "/lib/modules/$(uname -r)/kernel/net/ipv4/netfilter/ipt_multiport.$EXTN" ]; then
echo "Since the ip_tables, ipt_state, and/or ipt_multiport modules do not exist, KISS can not function. Firewall script aborted!"
exit 1
fi

After commenting these lines out the KISS script should run fine.

Hilarious Support Email

Today, the following email landed in our support mailbox:

Honourable trojan hunter. programs during the scan clearly shows that the magnifying glass does not reach the corners of pages. it is possible that computer viruses will remain in parts of the files?

The email had the following image attached:

It seems the user is concerned that files are not getting thoroughly scanned since the magnifying glass in the scan animation doesn’t completely sweep each file icon. Either that or he’s pulling our leg 🙂
