Maybe your kernel isn't set up right.

Go to /usr/src/linux
become root
type "make xconfig"
select the tab Networking Options
make sure "Network packet filtering" is enabled

for more iptables options, scroll down to the tab "IP: Netfilter Configuration"

If "Network packet filtering" isn't enabled, you have to enable it, and recompile the kernel. Search around for how to

Are you trying to run your own firewall?

make sure the iptables directory is in your PATH variable, if it isnt already. try:

Code:
PATH=$PATH:<directoryname>
(EDIT - i think i might have read this wrong. Do you mean the command isnt working, or you just dont know the name of the command itself?)

i know the name of the command and i have a book that tells me what i need to put in to make my own rules for a firewall. on a previous install it worked without a single problem. but, for some reason, this time it says the command iptables is not found.

Use the whereis command to find the location of iptables
Code:
whereis iptables

iptables: /sbin/iptables /lib/iptables /usr/share/man/man8/iptables.8.gz

this is what it gives me. do i have to be in one of these directories for iptables to work or something?

No.
I just wanted to make sure that iptables was installed correctly.

First of all, are you logged-in as root when you try to use the command ?
By default, only root has the /sbin directory in its path.
As root, type:
Code:
echo $PATH
Hopefully, the /sbin will be present.

If you are suing to root the use:
su -

Not:
su

This loads root's paths which includes /sbin without that you can run:
/sbin/iptables
