Henry,

I'm resonably certain that RH9 has a gui program call services or something to 
that effect.  That should allow you to control which services start in which 
runlevels.  Worth noting is the fact that on my gentoo system on startup I 
have over 170MB of memory used and i dont have too much extra starting up...X 
and KDE use alot of memory.  But despite that  170MB being used and another 
74MB being reserved as shared video memory and texture memory my laptop 
almost never touches the swap space so theres more than enough free memory 
available.

Dan,

I'm using a 2.6.8-1-686 kernel image in Debian
testing.
I have the kernel-sources-2.6.8 in my /usr/src
directory.

I got the kernel source from Apt(not kernel.org), and
it doesn't start with linux-(version), its just
kernel-sources-2.6.8. Should that be a problem or no?
I didn't think so but just wanted to be sure.

Also, I'm trying to compile HostAP, which is a
wireless driver which enables Monitor mode which is
required to run Kismet. My wireless card is a Linksys
WPC11 Version 3 and I've confirmed that it works with
Kismet at the following site
http://www.kismetwireless.net/cards.shtml. Are you
familiar with setting up HostAP at all?

I wasn't aware that the prebuilt kernel's came with
.config files. Where are they and what would I do with
them in order to compile HostAP as a module?

Thanks for the help,
Dave

Henry,
One of the things to keep in mind when it comes to linux and RAM usage
is that Linux wants to have all of your RAM being used all of the time.=20
That is, if your RAM is sitting there empty and not doing anything, then
it is being wasted.  So, Linux will usually keep files cached in memory
if there is nothing else that needs that memory.  I'm also running red
hat 9.  My machine has been on for 40 days.  When I load up system
monitor it says that 371/376 MB of memory is used.  This is true, but
when I run the program 'free' in the console, on the second line of
output, it shows me that only 195MB are used for applications and that
the remaining 185 MB is being used for caching files.  This will
probably give you a more realistic measure of how much memory your
processes are using.

--Mark.
