How to obtain Fedora Core Kernel Sources?

Wed May 3 06:42:48 UTC 2006

Hello list,

I am running Fedora Core 4 with the Kernel 2.6.15-1.1831_FC4 on IBM Thinkpad 
T41P. 

To enable the usage of an internal modem, I need to compile and install the 
slmodem as a kernel modul. The installation fails, because I have no kernel 
sources in /usr/src/linux. My question is quite simple (as I hope): How can I 
obtain the sources? I would like to use yum to get them, but I don't know the 
package name. If I use yum, is it satisfied that I get the right sources for 
my kernel? I am using the kernel 2.6.15-1.1831_FC4.

Cheers

Alexander
