Installing Kernel Sources

[Øyvind Lode]

Hi all.

This is probably a very dumb question.
I cannot install the Fedorda Kernel Source RPM package.

I think I did this once by running:
# yum install kernel-source
or
# yum install kernel-sourcecode

I have also tried apt-get but both apt and yum tells me that no packages 
found.

I searched one of the fedora ftp mirrors and found a file under updates 
called kernel-2.6.10-1.741.src.rpm
so I downloaded that manually and then tried:

# rpm -ivh kernel-2.6.10-1.741.src.rpm

but that did not worj either...

What's the name of the kernel source package I need to use when I run 
yum/apt?
