Peter,
A question, does binstats also take into account the dependencies of
libraries to other libraries. Binstats has shown me I have 113 unused
libraries, an I want to make sure these aren't used by other libraries
before I kill them off.

FYI, I received an email from the svgalib maintainer. Svgalib has to
be compiled with the BACKGROUND option commented out in the svgalib
souce package file Makefile.cfg because of changes in the new kernel.

I have a Yamaha CDRW 8424EZ, running on SUSE 6.4. My notes:
Set /etc/modules.conf:
alias scsi-adapter ide-scsi
options ide-cd ignore=hdc
Set /etc/lilo.conf:
label = suse64
append = "hdc=ide-scsi"
Everytime I reboot, I need to do:
depmod
insmod ide-scsi
Haven't figured out how to get the system to do that on boot.
Use yast to "install" CDROM as SCSI. This is needed to
use it as a normal CDROM (as compared to the
reader/writer activity under xcdroast).
So if your system is similar, check to see if "ide-scsi" is insmod'd.

Hi ,
I am interested in implementing Networking Protocol in Linux
(IPv4,IPv6,UDP,ICMP etc).
I would like to ask whether there is any tutorial website explaining how
to implement networking into Linux.
Or if there any good book for this
Thank you.

I'm wondering on this too, but in a different light. after
jumping to 2.4.0, I can only hop into X once. If I quit out of it back
to my console, and try to go into X, it dies, saying that it can't find
the 'fixed' font. It exists in /usr/X11/lib/X11/fonts (and yes, it's
listed in XF86Config), but after trying to go into X a second time, it
fails. Not sure of why yet.. has anyone seen anything like this?

I have a stupid question that I am sure someone here could answer. I am
completely new to Linux and I am trying to use Linux to assist me in
learning to program (complete newbie here too). I've written a couple of
very simple programs that just display test using printf statements. However
whenever I compile them with gcc and try to execute them from the terminal I
don't get anything but an error stating that Shared libraries are not
supported. Yet when I click on the file in KDE nothing happens of course,
but when I logout to the command line I see my intended output. Am I missing
something here?
Thanks for any help

Hi ,
The output will appear on the console where u execute your program.
BTW, how did u execute your program ? Are using the console application like
'konsole', gnome-terminal or xterm ?

The major versions of Linux on Macintosh platforms are, to my knowledge, ONLY
supporting Power PC processors. I've tried PPC Linux, and just lately, suse
Linux for the Macintosh. Mostly, a LOT of stuff was broken with PPC Linux, and
almost everything works with suse. I've tried older versions of TurboLinux and
Yellow Dog, but didn't like either.
In your case, however, the only support for 680xx processors is McLinux, which
I've installed successfully on an old Performa I used to have. VERY slow, but
usable. Anyway, point your browser to McLinux, and start looking.

Hello,
I need to do disk read and writes bypassing the buffer cache. (i.e I

interface.
Does any one know some trick/hack so that all read and write results

I'm using the Redhat 6.2 and Kernel2.4.
But, I can't mount cdrom.
I have a IDE cdrom
My command is following
# mount /mnt/cdrom or
# mount -t iso9660 /dev/cdrom /mnt/cdrom
My error message is
'mount: special device /dev/cdrom does not exist'
What's problem?

Where is it looking for its executables? Make sure your path is
complete.
And ask the author, not me (or read the code: it's a simple script).
Whatever the answer is, you can force it easily by adding the lib
directories to your path and making the lib* executable.
And yes, it is normal to have plenty of unused libs on your system.

The one shiped with Red Hat 6.2 is dated 23 July 1993,
but perhaps it is just Red Hat who is far behind?

I'm wondering why you want to make a new program, why not
just extend the existing automounter which can do a lot of
nice things?
The idea of automatically unmounting the CD-ROM when the
eject button is pressed sounds great to me. (In fact I
think that is probably the most important feature not
found in the existing outomounter.)
I don't know if the drive reports button press for the
eject button when the drive is locked. But it is possible
to be told if the tray is opened or closed, so you could
do something like unlocking the driver whenever an
immediate unomount would be possible, and unmount the
filesystem when disk is ejected. And of course lock the
drive again when someone starts using the filesystem.
Of couse if the drive reports the eject button that would
be much better.

That could be possible, I once wrote a scheduler in Turbo Pascal
using as litle as three inline assembler instructions. The only
thing that had to be done in assembler was restoring the SS
register.
But there will need to be some architecture depenent code. And
it is much more important how much of the system is architecture
dependent than how much is written in assembler.

XF86 3.3 or XF86 4.0 does not make any difference, but perhaps
it makes a difference which version of xterm you use.
The pts' are used by xterm and also by many other programs,
even programs like screen which can run without any X server
use pts'. Try stracing a program using pts' with /dev on an
ext2 filesystem and /dev/pts on a devpts filesystem. And try
stracing the same program with the entire /dev hieracy on a
devfs filesystem.
Perhaps the problem has something to do with /dev/ptmx which
is used to create the /dev/pts entries.

BTW, examining some binaries led me to believe that there is (or there

any kind of documentation about that. Can anybody sched some light here?
I don't need it, but I'm just wondering.

Check <URL:http://www.linux-m68k.org/>
Notice that you need to have MMU and FPU.
I don't know if theese are builtin to
MC68030 or if they have to be installed
separately.
If you want to do some serious work
you will probably also need a harddisk
or access to a network drive.

Normally /dev/cdrom is a symbolic link to the device driver
for cdrom. Check that the link exists and points to the
correct device.
What the correct device is depends on system configuration.
With ATAPI drives you have two different options, I think
IDE-SCSI is the best.
You need a kernel arguemnt that could be "hdc=ide-scsi"
assuming the CDROM is master on the secondary IDE
controller, otherwise "c" has to be replaced with another
letter.
If you are using LILO you will find documentation on
kernel arguments in the directory /usr/doc/lilo-0.xx.
You need to load the ide-scsi driver: Log in as root and
type "insmod ide-scsi".
And you need to make sure cdrom points to the correct
device which will be "scd0" if there are no SCSI controller
in the computer. Type "cd /dev ; ln -sf scd0 cdrom"
