The base distro of cdrecord comes with mkisofs. mkhybrid is a
*replacement* for mkisofs (and eventually will be merged into) that will
create an HFS/ISO or an ISO+Apple extentensions image (and Joliet,
RockRidge, and all sorts of hybrids and bootable CD images).

Here is an excerpt from "/usr/src/linux/Documentation/scsi.txt":
The scsi-core contains the core of scsi support. Without it you
can do nothing with any of the other scsi drivers. The scsi core
support can be a module (scsi_mod.o), or it can be built into the
kernel. If the core is a module, it must be the first scsi module
loaded, and if you unload the modules, it will have to be the last
one unloaded.
Could this be the problem; my system has 'scsi_mod' built-in.

Built into GNU-cc compiler and run-time libraries. Use the -p or -pg to
have profiling code inserted into the programs you compile, and when
linking. You then run prof or gprof to analyze the results. You can read
more about this in "Using and Porting GNU CC" by Richard M. Stallman, or
"Programming with GNU Software" by Loukides & Oram.

No, it _is_ quite _completely_ true.
There is _NO SUCH THING AS A FILE EXTENSION on Unix_.
Filenames are composed of _one_ component, and that is the filename.
They are not composed of a structure that contains a name and an
extension.
You can _pretend_ that what you have is an "extension," but it is
_not_ one, not in the way that there are extensions as separate
components ("namespaces") of a file name as is true for such famous
alternative operating systems as VMS, MVS, OS/2, Windows NT, GECOS,
and MS-DOS.
You can use something that looks somewhat like an MS-DOS "extension"
at least insofar as it involves putting a dot and two or three letters
at the end of a filename; the more correct term for that is a
_suffix_. It shares the same namespace as the remainder of the
filename; it does not provide a distinct filespace, and thus is not
accurately termed as an "extension."

I am getting quite irritated at how often people keep perpetuating
this load of fetid dingos' kidneys.
This is _NOT_ a problem with ext2 kernel code. People keep claiming
that it is, but apparently do so after Not Reading The Code.
For a not-entirely-irritated reading on this that clearly places the
blame in the (right) place, which is to blame compliance on POSIX and
ISO/ANSI C for the problem, see:
<http://www.uwsg.iu.edu/hypermail/linux/kernel/9912.3/0009.html>
It is far more entertaining to go with Alexander Viro's comments:
Q: is it true that ext2 has 2Gb limit on file size?
A: BS
Q: so how comes that I can't create files larger than that?
A: because VM in Linux 2.2 and earlier can't cope with files larger than
2.2 on 32-bit architectures. Regardless of filesystem.
Q: will reiserfs help?
A: what part of "regardless of filesystem" is too hard to understand?
Q: OK, so what can I do, I'm stuck with 32-bit box?
A: use 2.4 _or_ 2.2 with LFS patches _or_ FreeBSD. All of them will handle
more than 2Gb on ext2.
Q: I've done that, and half of utilities doesn't work
A: That was a question?
Q: OK, _why_?
A: because if libc thinks that offsets are 32 bit it's not going to pass
anything larger to the kernel
Q: what should I do?
A: get sufficiently recent libc. And learn to use search engines, already -
all that stuff had been beaten to death _many_ times.
Q: why...
A: excuse me, what was your username, again?
Q: ... are you so... Hey, what's up with this NIC? It's sparAAAAAASSSHHH<thud>

The canonical site for picking and choosing window managers is
<http://www.PLiG.org/xwinman/>
As for configuring it, there are two pieces:
a) Each WM potentially has its own individual configuration scheme;
look to the docs for the WM in question for info on that.
b) Most Linux distribution tend to have some scheme for invoking the
window manager; this often involves configuration in the file
$HOME/.xsession, although that can vary...
If you specify what distribution you are using, it may prove easier to
provide straight answers. (Mind you, if we aren't using the same
distribution, it may be tough to predict things, but it's at least a
starting point for discussion...)

Have you any spare IRQ's? I moved IRQs all around to get things to work. I
eventually ran out of IRQs when I added a NIC to my old machine. To get
that to work, I removed my printer from the parallel port and stuck the NIC
there, That machine has the mouse at IRQ 4 (serial port mouse), the UPS
cable into seria port at IRQ3, sound board at IRQ5, modem at IRQ 7, NIC
someplace, two IDE disks and CD-ROM higher up. Floppy disk and floppy tape
down near the bottom, and so on. Fortunately my new machine has 24 IRQs. I
do not know how they did that, but they did.

I'd like to use cdrecord with an ATAPI/IDE recorder on my Dell I7500 laptop
running RedHat Linux 6.2 (kernel 2.2.14) but am not having any success in
getting the IDE SCSI emulation to work. The situation hasn't been made
clearer by the various HOWTOs, etc., some of which state that I *must*
enable IDE/ATAPI CD-ROM support and others which say that I should do the
opposite. (Jorg Schilling's README.ATAPI on his cdrecord pages says both! ;-< )
Which is it?
My kernel is currently configured as follows:
Y Enhanced IDE/MFM/RLL...
Y Include IDE/ATAPI CDROM
M SCSI emulation
M Loopback device support
Y SCSI support
Y SCSI CD-ROM suppport
Y Enable vendor-specific CD-ROM extensions
Y SCSI generic support
Y ISO-9660 CDROM filesystem support
Y Microsoft Joliet CDROM extensions
This is pretty much in accordance with the CD-Writing HOWTO. My lilo.conf entry
reads
image=/boot/vmlinuz-2.2.14-5.0rbd
label=cdr
read-only
root=/dev/hda5

When I boot I see the following in /var/log/messages:

Not only is the CD-RW not visible as a SCSI device, it no longer works as
an ATAPI/IDE either when I load it with an ISO-9660 CD:
# mount -t iso9660 /dev/hdc /mnt/cdrom
mount: /dev/hdc is not a valid block device
One potential complication with my system is that it does have a real SCSI
bus (via an Adaptec SlimSCSI 1480 card) but my ATAPI/IDE CD-RW is obviously
not on that bus:

What's wrong with this picture? Do I need to make certain static modules in

Does ide_scsi not work when there's a real SCSI bus on the machine?
Any other ideas?
Thanks in advance for any help that anyone can provide.

I just looked in the BlackBox catalog, since it is the only one I have handy. I have no
idea if they are the cheapest or not (probably not). But at $25/port, what is the
fewest number of ports you can get? The first one I saw was US$289.00 for 8 ports, or
$36.125/port. The cheapest one I saw was US$229.00 for 8 ports, or $28.62/port.

Subject: Re: circuit layout program
As another responder queried, are you looking for "layout" or "schematic
capture"? Given the context, I'd infer schematic capture + simulation. You
want something which will allow you to graphically (or not...building SPICE
decks in a text editor builds character!) create a circuit, and then analyze it
(simulation).
I've no particular relevant experience, except that I've collected quite a few
links on the topic. Here are those which may be most useful.:

Check this wired article. If successful, this computer is the 24th fastest
computer and it runs Linux.

Subject: console permissions
Date: Mon, 18 Sep 2000 21:45:19 -0500
We at UAB are using Redhat linux for a particular project. We got a problem
with the permissions. X is working only with the root and when i try to run
with my user name it is displaying
Perhaps you do not have console ownership?,
and it is prompting for some command!
I tried the following 3 things to get around this problem.
1. Added the following line in the /etc/pam.d/xserver
account required /lib/security/pam_permit.so
2. chmod go+w /dev/console
3. rpm --freshen *.rpm
still not happy. I mean startx runs fine as root, just not as any other
normal user!
what else could be done.
thanks

I have a RedHat 6.2 laptop with a 10/100Mb PCMCIA card that is usually
plugged into my LAN at the office, but I need to occasionally take it
off-site and dial into a PPP server on the same LAN via a PCMCIA modem.
I've read through some of the PPP HOWTO material but am unclear as to
whether or not I can expect conflicts between the software configurations
of these two interfaces. (The IP host addresses of the two will be different,
and I do know the PPP IP address that will be assigned to my system in
advance. The network numbers, netmasks and broadcast addresses are identical.)
Right now my system is happily configured over 10/100bT. Will I break
this configuration by running any PPP configuration scripts via linuxconf
or otherwise? What if anything will I need to reconfigure each time I want
to switch from one interface to the other?
Other questions:
(1) Does anyone know if my PCMCIA Psion Dacom 56k+Fax Gold Card modem
will actually work for this?
(2) What's the most reliable up-to-date reference available for PPP setup?
(The PPP HOWTO I've seen looks horribly old.)
Thanks in advance for any help!
