I want to recompile kernel after patching it. I have fedora core 8. here is some of the description.

[root@localhost local]# uname -a
Linux localhost.localdomain 2.6.23.1-42.fc8 #1 SMP Tue Oct 30 13:55:12 EDT 2007 i686 i686 i386 GNU/Linux

[root@localhost src]# pwd
/usr/src
[root@localhost src]# ll
total 16
drwxr-xr-x 4 root root 4096 2008-07-16 22:02 kernels
drwxr-xr-x 7 root root 4096 2007-11-12 08:25 redhat
[root@localhost src]# cd kernels/
[root@localhost kernels]# ll

drwxr-xr-x 18 root root 4096 2008-07-16 16:02 2.6.23.1-42.fc8-i686
drwxr-xr-x 19 root root 4096 2008-07-16 22:03 2.6.25.10-47.fc8-i686

I have two kernel version in my kernel directory. Its confusing me.
Can somebody plz describe the steps. i want to install and configure kernel 2.6.20. I also want to patch it with some tproxy patches

thanks

But you don't have the source for 2.6.20
Your running kernel is 2.6.23
You seem to have sources for: 2.6.23 and 2.6.25
