Question Kernel Upgrade

I am new to Linux. I have installed Debian and am running the 2.20 kernel. I downloaded the network install version.

I would like to upgrade to 2.4 or 2.6. The main purpose for doing this is to run iptables.

So now for my questions: How do I preserve the hardware configuration I currently have during the upgrade? I am not entirely sure of what hardware is running on my computer or what options were used to compile the kernel that I have, but the current kernel works. I have run make menuconfig and was presented with options that I have no idea the correct answers to for my system. Does anyone have any thoughts as to where on my file-system I might find the .config file that was used for my current installation, if this could be used for the 2.4 kernel compile? Or ideas for a safer, albeit larger, kernel configuration that would give me the iptable functionality?

Many thanks in advance.

You couldn't use the 2.2. .config to build a 2.4 kernel. Hardware can be found with lspci -v or cat /proc/pci then find out what modules you need for them and make sure you compile those options in. Also mke sure that in file systems you have the module for the filesystems compiled in 'hard' -- not a module but actually in or no boot. Iptables are found in networking options --> netfilter and then a sub menu will appear a few lines down: ipnetfilter configuration -->where you can check off the individual options for iptables. Succesful kernel building takes practice, prepare to fail and be OK with it, you'll still have 2.2 but MAKE A BOOT DISK!!
