Hello,I have got one question. I need to download kernel headers for my debian kernel 2.4.20-bf2.4-xfs,but I don't know which one of them should I download(there are quite many of them for download).
Thanks

Where are you trying to download them from? If possible, post the list you can choose from.

I am trying to download them via apt-get(apt-get install kernel headers)and I recieve these possibilities:
kernel-headers-2.4.18-1-k7 2.4.18-8
kernel-headers-2.4.18-1-k6 2.4.18-8
kernel-headers-2.4.18-1-686-smp 2.4.18-8
kernel-headers-2.4.18-1-686 2.4.18-8
kernel-headers-2.4.18-1-586tsc 2.4.18-8
kernel-headers-2.4.18-1-386 2.4.18-8
kernel-headers-2.4.18-1 2.4.18-8
kernel-headers-2.2.20-idepci 2.2.20-5woody3
kernel-headers-2.2.20-compact 2.2.20-5woody3
kernel-headers-2.2.20 2.2.20-5woody3
kernel-headers-2.4.21-sparc 31
kernel-headers-2.4.21-2-k7-smp 2.4.21-2
kernel-headers-2.4.21-2-k7 2.4.21-2
kernel-headers-2.4.21-2-k6 2.4.21-2
kernel-headers-2.4.21-2-686-smp 2.4.21-2
kernel-headers-2.4.21-2-686 2.4.21-2
kernel-headers-2.4.21-2-586tsc 2.4.21-2
kernel-headers-2.4.21-2-386 2.4.21-2
kernel-headers-2.4.21-2 2.4.21-2
kernel-headers-2.4.20-speakup 2.4.20-3
kernel-headers-2.4.20-3-k7-smp 2.4.20-9
kernel-headers-2.4.20-3-k7 2.4.20-9
kernel-headers-2.4.20-3-k6 2.4.20-9
kernel-headers-2.4.20-3-686-smp 2.4.20-9
kernel-headers-2.4.20-3-686 2.4.20-9
kernel-headers-2.4.20-3-586tsc 2.4.20-9
kernel-headers-2.4.20-3-386 2.4.20-9
kernel-headers-2.4.20-3 2.4.20-9
kernel-headers-2.4.18-bf2.4 2.4.18-6
kernel-headers-2.2.25-idepci 2.2.25-3
kernel-headers-2.2.25-compact 2.2.25-3
kernel-headers-2.2.25 2.2.25-3
kernel-headers-2.2.20-udma100-ext3 2.2.20-7
kernel-headers-2.2.20-sparc 9
kernel-headers-2.2.20-reiserfs 2.2.20-4

I'd get kernel-headers-2.4.20-3 2.4.20-9. Should work fine.
