In fact, the URL is

ftp://ftp.scientificlinux.org/linux/scientific/42/SRPMS/vendor/errata/

I downloaded the kernel sources and I'm going to patch and recompile them to fix the bug with "iptables -t mangle -j TTL" producing 
"No chain/target/match by that name".

I'm curerntly running version 2.6.9-22.0.1.EL of the kernel. May I switch to the most recent version (2.6.9-34.EL)? If so, what do I 
have to do after I recompile the sources? Do I have to reinstall the whole SL or is there any way to replace the kernel only?
