Hi everyone,
I have been attempting to get the hang of the 'dd' command and actually
succeeded in creating ISOs of various CDs, DVDs and even a hard disk. For
DVD/CD disks I dismount it first, because its set to autoload, before
executing the DD command.
Then I tried a Music CD and dd keeps reporting and error: device
(/dev/cdrom) not found. Mount(ing) it, umount(ing) it trigger the same
error. Yet, the music player and the file browser find it ok.
I have tried to list all the disk devices with mount but I don't know enough
to extract the correct device name when an Audio CD is loaded.
Is there another command line parameter I should be using? Or do I need to
tell dd the media file system?
Thanks in advance. I will keep googling, you never know I might actually
find a solution. :-)

I use a CD burning program to create ISOs - you can generally tell it
to create an ISO file instead of burning a disc. Currently I use
Brasero, but I've seen the same functionality in other CD burning
programs.

Thanks Russ,
I have Brassero and that works like a treat. I also have several Windows
ISO creators and they also work fine (most of the time). I just want to
understand why dd is messing up when I use an Audio CD. I feel certain its
to do with the file system used in Audio CDs. And also, how to I get a
listing of all the media devices including DVD/CD players?

Audio CDs don't have a filesystem
(http://en.wikipedia.org/wiki/Red_Book_%28audio_CD_standard%29)
compared with CD-ROMs which use ISO9660 or UDF.
I found this article whilst googling:

Thanks Chris,
I have seen this article whilst googling yesterday. And I have also picked
up, eventually, the fact that Audio CDs are different. dd can't read audio
cds for that reason. Anyway, there are quite a few utilities that can do
what I want. This was/is an educational exercise and I'll be interested to
see if dd can be used to backup dual layer and copy protected DVDs.
I'll give that a go next.

Hi, i am new to the group.
I am running ubuntu 10.4 LTS , hosting my schools website, moodle server,
mahara and drupal.
My local authority is having issues providing me with shibboleth
authentication so i have decided to go it alone.
My machine authenticate against all users on my microsoft network, as i am
testing squirrelmail at the moment, and my students host websites on this
linux server too. Using the LDAP username and password.
I am therefore trying to configure Shibboleth IDP on this machine, i seem to
have followed the instructions below (i can only find them for tomcat 5.5 -
whilst i have tomcat 6 natively installed)
"http://www.edugate.ie/workshop-guides/shibboleth-2-identity-provider-installation-linux-debian-or-ubuntu"
I am unable to deploy my IDP WAR file correctly or i think that is the issue
it keeps telling me the context path is incorrect.
"FAIL - Application at context path /idp could not be started".
I know its quite a specific error.
Any help would be appreciated

Ooh, beat me to it.
Peter is not hte bogey man he may appear after posting that reminder
about thread hijacking, he's a teddy bear really ;-) It actually
makes more sense to start a new and separate thread because that way
anybody who has binned the rest of the 'DD' thread will still get your
plea for help. Worth remembering for in the future.
Take care.
