Recompile redhat kernel so ARPD is supported


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...

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

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.
