CD Burning

[jim bob and joe bob]

This must seem like a ridiculous question but here goes. How do you
check the md5sum? Is it done from Linux or MacOS? If from linux, how
can one be expected to do it if you have no linux installation yet?

check the md5sum? Is it done from Linux or MacOS?

I answer here, bookmark this ;)

Along with iso images (for example foo.iso) there is always a file called
foo.md5 or similar. Inside there there is an alphanumeric value like this:

dc36329c6400345cb2d013c144e55de2

So to check if the iso is correct, you should have the same md5sum.
To check it you can use the md5sum command (I think in the OSX shell it is
present, just try it):

$ md5sum foo.iso

or, if you have the .md5 file, put it along with the iso and issue

$ md5sum -c foo.md5

Ok? Further questions?

You need a program to compute the MD5 sum. In Linux, this program is
called md5sum, and is usually installed by default. Offhand, I'm not sure
if it's included with Mac OS (it might be included with Mac OS X, but I
doubt if it's included with pre-X versions of Mac OS). Try a Google search
on "md5sum MacOS" if it's not installed on your system.

Mac OS X doesn't offer md5sum (yet) but you can actually calculate the
md5 checksum by invoking the following command in a Terminal:

$ openssl md5 your.iso

compare the output to the one (named your.iso.md5) located on the server
where you downloaded the image.
IMPORTANT: Calculate the checksum _before_ you mount the image (e.g.
Disk Copy)

Thanks. I would like to point out that if one does not already have a
running linux system recommending md5sum is a little silly. In
practice, I have had trouble burning cds that work but I do not believe
it has been because of corrupted downloads. Rather it has been operator
malfunction or just using the wrong burning software.

It is not true. The fact that an utility is not installed by default does
not mean it is useless.

especially as it is also available on other systems.
eg the very first item when I googled for md5sum was a download for
windows.

Windows? Wash your mouth out with soap!! I have not yet found a
version for pre X macs.

However there are some versions of Python for MacOS 9, for example, and
there is a python MD5-checking script.

I have Python. I installed it to try and run bittorrent but failed to
make it work. Not sure what I did wrong.

Use Azureus.

I guess I need to be more specific with my rantings. What I have found
is that if you start from MacOS pre X system and try to go to Linux
there is one hurdle after another to be surmounted. The iso images are
difficult to burn. The X-windows configuration is a real pain. Python
failed me for reason(s) that I do not understand. Azureus seems to not
be available for pre X MacOS. Besides it is a Java app and Java on the
Mac is notoriously flawed.
On the other hand, if you succeed in getting Linux to run on one of
these antiquated machines it does run very nicely. There are still
problems to overcome. I have yet to get any sound at all. Not sure
why. Xcdroast will not find my burner because it is IDE, not SCSI. Cds
mount just fine from the file system, just no burning. The last word on
that was that at least a 2.4 kernal was necessary, which I am running.
Much of the information for previous kernals involves compiling a kernal
with custom features. Compiling a kernal (for me at least) would be
another steep learning curve. It is probably something I will learn if
I live long enough.
I guess my point is that even though the people on this list are helpful
to the extreme, getting Linux up and running on an old mac in any kind
of useful configuration does not seem to be for a novice.
That's my rant and I'm sticking to it.

Well, I didn't know you are not using OSX, on an "old" mac :)
Actually I know there is a way to run bittorrent on OS9, but I don't
remember where I read it.

As for linux: the first point you have to make very clear when trying
something new is that it will be *different*.
I switched to linux 3 years ago and never looked back, but I perfectly
understand that other people might not find it as good as I find it, and
more than this I understand that many people DON'T WANT to read *anything*
before using a computer. I don't agree with that behaviour, but that's the
way it is.
To use linux in a quick and proficient way, you have to learn a bit of its
inner mechanics. Period.

I mostly agree with you Jack. I have learned quite a bit about linux
already. Some I have read. Some has been with your help and the help
of others here. Some from experimenting with the system.
What I was getting at with all this was that it can be daunting for one
to try linux from little or no knowledge of it. Many of the tricks that
get suggested are really beyond the ability of a complete novice.
I think we agree: the learning curve is steep to begin with.
Until linux is as easy to install as MacOS or at least as easy as
Windoze its user base will grow slowly.

I think you have been "unlucky" to start your linux experience with a
tricky machine as an old mac can be.
On a newworld machine (not to speak of x86 arch) you would have probably
felt much more comfortable and much better assisted: unfortunately the ppc
scene got "alive" in the last year or so and support for older machines is
hard to find, since few people ran linux on those machines.
I can suggest you to google in the linux.debian.ports.powerpc archive:
that is the usenet gateway to the debian-ppc list, which is full of good
advice. Maybe you can find some useful information there.
Hope it helps!

Maybe not.

% which md5sum
/sw/bin/md5sum

This is on a 10.3.7 machine. I did install the developer's CD, the one
containing GCC, so that may be where it came from.

Is it possible that you have fink installed on your system? The path /sw
sound like. But I might be misinformed since I don't use fink anymore.
By the way: I guess the non-developer version of OS X also comes with gcc.
