I have no idea what you are talking about
Please use a title which describes the problem.

sorry bro, but it's really hard to understand your English - are you talking about the compressed Linux kernel on a bootable floppy? if so, just use any newer distro, and take a look at the .bin file; GNOME's desktop can extract it visually for you.

if not, rephrase it for me, would you? thanks

If you want you can send mails directly from LQ to member but that is a bad idea. This is a forum and open to all and should be. If some other members get stuck with same problem this thread can solve problem for those. Why not rephrase your question with neat title so that members understand what you are talking.

It does appear to be a kernel file. I was not, however, able to uncompress it (nor could I uncompress my kernel).

Searching on "vmlinuz compressed", I found many hits, including this:

It appears that the kernel (vmlinux) is a self-extracting file which includes the gzip decompression code. Do the same Google search that I did and you can dig further.

To get more help on this, you should tell us more about the overall objective.

uncompressing vmlinuz

I can't believe how hard it is to find an answer to this question... And the first thing reply-ers tend to ask seems to always be: "why do you want to?" so I'll start with that:

My Security Program (GFI Languard) wants to be able to access an uncompressed kernel (vmlinux) in order to check for rootkits. I don't know how or why, just that it says it does.

So. My work machines are CentOS 5, amd-64 bit. I really don't want to build a new kernel from scratch, since (I assume) it must exactly match the compressed kernel used to boot. How can I get one, please?

Section 10.1 on this page, paragraph #3, seems to have your answer:

The vmlinux is the uncompressed built kernel, vmlinuz is the compressed one, that has been made bootable.
So, having built your kernel at some point, locate the vmlinux image (the pre-compression image) and hand that over to your GFI program and see what it says.
