Hi all,
I am currently working on developing some firewall and all the security stuffs, I am referring once nice tutorial available on line
It is at
http://iptables-tutorial.frozentux.n...-tutorial.html

It is really a nice document for each and every security guy to go through once,

My problem lies with the kernel options we have to set while preparing our linux box for a firewall stuffs, ( this is the point number 2.2 -kernel setup in above online tutorial)

We have to enable various options while doing make config - this is the command we have to execute when we want to compile our kernel.

The kernel options are like

CONFIG_NETFILTER
CONFIG_PACKET etc...

which we have to enable for firewall stuffs.

Is there any way out using a simple shell script to set all these kernel options ? rather than going through it one by one and setting it.

I want to do it with one script is it possible ? and how ?

I am somewhat new for linux ( 2-months only !!!) may be wrong somewhere.

Yes, it's possible, I think; you're looking for regular expressions.
So take a look at a sed or even better, a gawk tutorial:
http://www.vectorsite.net/tsawk.html is quite a good one.

For example, you could search for one line, print the first word before the tab, add '=yes' to the line, and get it printed between the other lines.
Also read the man pages of cut and paste, this may be of great use.

This is quite general, but I hope it helps.
