Aynone any ideas how to do this? I've read some links, lots of which describe alternative ways of doing it. Whats the quickest and most efficient way; it looks like ammending the .config file with the single line change and then running make oldconfig will work, what else is needed after this? OS is redhat 6.2 on x86; been using this link: http://docs.redhat.com/docs/en-US/Re...dularized.html

Thanks guys

redhat 6.2? Surely you're jesting ... that's from 2000, and well and
truly out of support.

Huh; no?

http://en.wikipedia.org/wiki/Red_Hat_Enterprise_Linux

"Latest stable release 6.2 / December 6, 2011; 5 months ago".

Unless this is one of those "I know unix better than you" situations and a minor mistake or misunderstanding concerning the release cycle will lead to my humiliation?

Perhaps you're referring to the link I posted from redhat 3; well yeah that is old and crap, but sadly I can't find anything newer; clutching at straws here, surely this is a common task, it's such a minor change too...

http://wiki.centos.org/HowTos/Custom_Kernel or http://www.cyberciti.biz/tips/compil...kernel-26.html or http://www.cromwell-intl.com/unix/linux-kernel.html or http://www.linuxforums.org/forum/ker...nel-2-6-a.html or ...

4 different methods... Like I said; easiest and quickest. I literally need to make one change "CONFIG_ARPD=y"

Also.. Just to be clear; I have done research, I tried to make that clear when I asked the question. I've done research, asked in the correct area of the website and understand the concepts of what I'm trying to achieve. I had a tinkering I'd get some backlash given that this is a common task - but please, I just need to enable one thing in the kernel (which I suspect will require a recompile); give me a hand will you

redhat 6.2 != RHEL 6.2

Ah, ok thanks - was not aware of this I mean RHEL anyway.

If you can wait for another 2-3 weeks, the next version of centosplus kernel will have that option enabled. Please see:

http://bugs.centos.org/view.php?id=5709

But it you want to build your own kernel yourself, follow the Custom Kernel article. That is written specifically for RHEL/CentOS/SL kernels.

Some newbie ...
Doesn't say much (or often), but it obviously pays to listen.

I can't remember how many kernels I broken with just "one change" ...

Thanks toracat, I'll give this a shot and see if I get anywhere with it; your help is much appreciated.

We need this functional now, so it will probably involve a recompile. What I was really asking was whether there was a quicker way of doing this via kernel headers or something, but it seems like there isn't. All I needed was one link, someone saying do this and that was it.

Big thanks

I've just got this response from somewhere else; looks like a recompile was not needed:

"It probably looks like this:
CONFIG_ARPD is not set
Change it to: CONFIG_ARPD=y or better yet: CONFIG_ARPD=m then just configure it to load as a module"

In RHEL kernels, the default option for CONFIG_ARPD is either Y or N. I would just go ahead and make a change and rebuild the kernel. If you just follow the wiki, it should not be very difficult (saying this as a maintainer ).

The wait was actually only 6 days.

kernel-2.6.32-220.13.1.el6.centos.plus with CONFIG_ARPD enabled was released on 2012-05-16.
