iptables on 2.6

[nikhil]

Hi,

I have kernel2.6.0 running on redhat 9
My .config file in /usr/src/linux-2.6.0 shows
CONFIG_IP_NF_IPTABLES=m
CONFIG_IP6_NF_IPTABLES=m

and I also have the necessary netfilter files under
/lib/modules/2.6.0/kernel/net/ipv4

However when I run the following commands
#modprobe iptable_filter or
#insmod iptable_filter or
#modprobe ip_tables
I get the message
"FATAL: Module iptable_filter not found."

Does this mean that my iptable module is not compiled with the kernel? if so then why do i get the corresponding entries in my .config file?

Am i missing something?
also
#lsmod does not show me any modules as being listed

any reply is appreciated

thanks,
Nik

Do you have "modules-init-tools" installed?

Also, check in /lib/modules/2.6.0/kernel/net/ipv4/netfilter if it's there. If it isn't, you probably did something wrong while installing the modules.

[nikhil]

yes I have module-init-tools installed and the below dir is present as well.
/lib/modules/2.6.0/kernel/net/ipv4/netfilter
In the above dir I also have iptable_filter.ko,iptable_net.ko and another modules present.
When I try to do a modprobe <any-module-name> I get the message saying
FATAL: <module> not found

Is there something wrong with my modprobe configuration??

modprobe --version shows
module-init-tools version 0.9.13

I dont know whats going on...

thanks
Nik

Did you run depmod?

[nikhil]

yeah I ran
#depmod 2.6.0
and it did not give me any error messages either.

i hope thats the correct way to run depmod.

[Dolda2000]

If you are currently running 2.6.0, then you don't need to specify that. On the other hand, it doesn't hurt either.

Do you have /lib/modules/2.6.0/modules.dep and /etc/modprobe.conf?
If you cd to /lib/modules/2.6.0/kernel/net/ipv4/netfilter and manually run "insmod iptable_filter.ko", does that work?

[nikhil]

yes I have /lib/modules/2.6.0/modules.dep and /etc/modprobe.conf?
When i go to the lib/modules/2.6.0/kernel/net/ipv4/netfilter and manually run "insmod iptable_filter.ko" it comes back saying
"Error inserting 'iptable_filter.ko': -1 Unknown symbol in module"

I try to add any module using insmod and it comes back saying
"Error inserting 'modules-name': -1 Unknown symbol in module"

[Dolda2000]

I should have realized that... Sorry for wasting your time. What I meant was that you should "insmod ip_tables.ko". Did you try that one? I believe it should work. If it doesn't, check what symbols it is complaining on with "dmesg | tail".

[nikhil]

cool....insmod ip_tables.ko worked jus fine....
now do I need to run insmod iptable_filter.ko and stuff?

thanks for your help.
