Initializing IPTables

Synopsis:

Running iptables -L on a Slackware 8.0 system (after updating the kernel) generates these errors:

init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters
insmod /lib/modules/2.4.18/kernel/net/ipv4/netfilter/ip_tables.o.gz failed
insmod ip_tables failed
iptables v1.2.6a: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.


The Fix:
run the command: insmod iptable_filter
