kernel options - how do i know what options were compiled on install

Post by Jeff Can » Tue, 27 Jun 2000 04:00:00



I have a sun sparc classic running redhat 6.2 (kermel 2.2.14).  What i
would like to know is:

(1) How do i know what options were compiled into the kernel?  I did
the standard install off the cd, but would like to know what exactly
did and didn't get compiled in.

(2) Is there a way to get the exact same options compiled into the
kernel automatically if i upgrade?  I've spent a ton of time getting
the thing running correctly, and I am afraid of upgrading the kernel
and not knowing how to answer the compile time options and ending up
with a system that all of a sudden isn't running

-and-

(3) this whole thing is coming up because i want to run Team Fortress
Classic (a HalfLife mod) on masq'd client machines.  It looks like i
need this experimental loose udp patch for things to work, but i don't
know if its already compiled into my kernel or not, and am not sure
how to even check.  Does anyone know the answer to this question.

thx in advance,
jeff

Check the kernel config if you have the source package installed
'make menuconfig'

Use the option to save the config to an alternate file, save it in /usr/src
or wherever you want. When you uncompress the new source, just 'load
alternate config' and you should be all set
