does anyone know where to find the /etc/modprobe.conf and /proc/net/ipt_condition/ ..

Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

The other question is iptables needs the ip_conntrack module for connection tracking but I couldn't find that ip_conntrack in the lsmod but the iptables is still working fine. I can see the connection tracking by accessing the /pro/net/nf_conntrack. I am confusing here. So do we still need the ip_conntrack? and how can I see all the current and available modules in fc11?
modprobe.conf is a file usually located in your /etc folder or in a folder called /etc/modprobe.d/
I can see the ipv6 conntracking module in your lsmod output, but I do not see the ipv4 module.
Note that you should be looking in /proc, rather than /pro though that appears to be just a small typo, since you claim to be able to see the conntracking by looking in there -- I just wanted to point that out for your reference.
As for seeing ALL the modules possibly available on your current system, have a look in /lib/modules/$(uname -r)/ as this is where all your kernel modules are kept.
If iptables is working fine for you, chances are good that all the modules it needs, are available. However, if you are doing any ipv4 connection tracking (like maybe for FTP or whatever) then I would expect the nf_conntrack module to appear somewhere. If you look in the module folder I told you about above, and find the nf_conntrack or ipt_conntrack module, try modprobing it, using the `modprobe` command, and it should then appear in the lsmod listing.
Also, if I could suggest something everyone will find helpful: please put [code] tags around long lists of stuff like that, as it will make it much easier to read
Regarding modules missing, how can I get the modules and install it? Can I download modules from the internet? I tried googling for modules many times for downloading but it gives me a lot of unnecessary things. Some of them are about coding and some of them even suggest to recompile the kernel. I dont understand much about coding and I tried all the suggested solutions but still, I dont have the the modules I would like. I am talking about the ipt_condition, connrate, ipv4options of iptables. But the bottom line is how to get the module (download it from internet or have to recompile the kernel to choose the desired modules?) and how to install it?
Not sure if I mentioned it earlier vincent, but I have never heard of "ipt_condition" nor "ipv4options" -- this doesn't mean they don't exist, but just make sure you are looking for exactly the correct names, or you'll never find them
And no, you cannot just download the modules from somewhere. Kernel modules are created from the kernel source code, which generally means you need to rebuild the kernel to get modules that you do not have.
Now, in the case of Iptables, it is a package in and of itself.
How to try to explain it... The kernel has a built-in interface, for connecting with and interacting with the iptables code. The iptables package contains all the bits and pieces needed to create the packet filtering tables, but your kernel needs to be configured properly to SUPPORT iptables. So, when you want to do something using the iptables package, iptables will tell the kernel "hey, I need you to plug this module in", and if the kernel does not have the module requested, you get an error. In this case, you need too rebuild the kernel, and select options which will give you the missing modules you are looking for.
I'm sorry if this is a bit confusing; I am getting tired and going to bed soon! I hope it makes sense though!
Kernel modules must be built from your kernel source; you cannot download them.
from the fedora docs and wiki
As i recall " modprobe" has been replaced by HAL at boot and the needed modules will be turned on if needed.
there is no real need to ad things to the config file
--- or ---
Are you talking about the 3d card drivers ? ie. akmod-nvidia.rpm
Fedora 11 and 12 ( even better) should auto detect hardware at boot
BUT seeing as Fedora is a TESTING and " let's see how far we can push it , till it brakes " and "lets get the NEWEST code and cludge it together and see if it works" distro....
