I heard that the thing with up2date never worked properly. But on my system everything worked.

I read through thread and tried the up2date --get-source kernel command and it worked but I got the 2.6.10-1.770 kernel source but I'm running the 2.6.9-1.667 kernel so where/how do I get the source my kernel version or do I have to update my kernel?

please help

The newer kernel, 2.6.10, is an improvement over the stock 2.6.9 kernel, offering security updates and overall improvements.
Download the src.rpm and then follow the steps listed earlier in this thread specifically

BTW, the right way to obtain a pristine kernel source that was used to build your kernel is the following:

[root@gateway jsun]# rpmbuild -v -v --target=i686 -bp /usr/src/redhat/SPECS/kernel-2.6.spec
"
Then cd to /usr/src/redhat/BUILD/kernel-2.6.10
and build the kernel. Its easy to do. basically the commands are:

make xconfig (if you wish to customize your new kernel)
make (will make the bzImage and modules)
make modules_install
make install

reboot into your new kernel.

Good luck & have fun

I'm new to linux and have never messed with the kernel before so can you tell me if the new one will work well if I leave everything else the same or will I have to make changes to my other software as well?

Copy and paste that into the command line. THat will get you your source w/o having to upgrade the kernel. You can automatically upgrade the kernel using "yum update" as well. After yum is finished you can reboot and it will boot into your new kernel.

One question comes to mind, one main reason you need the kernel source is to rebuild and compile a customized kernel. But why would anybody want to recompile an older and obsolete kernel, when a newer and improved kernel is available? The current release has udev improvements and patched buffer overflow code among many other improvements. You can also just install the newer kernel through yum/gyum, apt/synaptic, or if you must, up2date. I personally hate up2date as it always hangs while upgrading, it seems to want to upgrade everything at once and overwhelms itself with TMI. gyum is a GUI front end for yum which works much better. apt/synaptic is also a very nice package manager system.

Back on thread, answering your post above, the newer kernel will work fine on your system without you having to do anything. If you upgrade through up2date or the other options above, the only dependencies affected will be system libraries but they will be upgraded as necessary and automatically by the package manager. Any programs you are using will not be affected at all.

Welcome to linux. Hope you're enjoying the experience. It really is a better and more powerful system than the "other" PC option out there. It will just take a little time for the learning curve to kick in. Don't hesitate to ask questions of any of us. We're all happy to help.
