howto load netfilter module..?

minike · 08-13-2006, 07:58 PM

hi.
I'm traying to run an app called "netstat-nat"
but when I do so, I get this error msg:
Could not read info about connections from the kernel, make sure netfilter is enabled in kernel or by modules.
So I did lsmod.. no 'netfilter' reference in there.
then, I tryied to load it with 'modprobe netfilter'
..but:
"FATAL: Module netfilter not found."

then I 'locate netfilter', and I saw a netfilter directory, instead of a netfilter.o or something like that.

so... what should I do to get that netfilter module(s) loaded, just to be able to run the netstat-nat app?

thanks in advance

If you use custom compiled kernel, it is likely that you missed out on netfilter. If you are using slackware's kernel. Try...

Code:

modprobe iptables

Code:

modprobe iptables_nat

If that doesn't work...check out the following directories

Code:

/lib/modules/kernel-version/kernel/net/ipv4
/lib/modules/kernel-version/kernel/net/ipv4/netfilter
/lib/modules/kernel-version/kernel/net/netfilter

Tux,

thanks 4 answering..
I'm using the 2.6.13 kernel provided in slack 10.2
never compiled a custom kernel, so.. it's the 'standard' one.
I did what U told, but.. nothing happens:

Code:

modprobe iptables
FATAL: Module iptables not found.

..and the same result 4 the modprobe iptables_nat cmd.

ok.. there's not /lib/modules/kernel-version/kernel/net/netfilter directory nor file, but I've been in the /ipv4/netfilter directory (as I said in my first post), and it's full of *.ko files (modules, maybe?)
the point is: what should I do with such files?
(really don't have a clue how to handle all of this modules thing)
