I just got myself a new CD-writer. I've never tried this before, but wanting to compare it's audio-extraction capabilities with my cd-rom's I tried with cd-paranoia, but no luck. Can cdparanoia work with ide-scsi? Thanks Hans == Download ringtones, logos and picture messages at Ananzi Mobile Fun. http://www.ananzi.co.za/cgi-bin/goto.pl?mobile

Yes.

How? I get something like: /dev/sr0 is not a cooked ioctl CDROM. For what it's worth, I installed SuSE with an old CD-RW drive in my machine, and SuSE set it up automatically. I just replaced the drive and put it on the same cable on hdc. This should work, shouln't it? What's weird is that if I boot without ide-scsi, I get the same problem with cdparanoia. In both cases I can mount and use data CDs. I haven't tried KDE's audiocd slave, will do when I get home, but doesn't that use cdparanoia anyway?

Ok, I tracked down the problem, sort of. I can't use cdparanoia on the cdwriter (ide-scsi) as a normal user, but it works fine as root. This is the message I get: --------------------------------- hans@sigaar:~/music/ian> cdparanoia -d /dev/sr0 -B -v cdparanoia III release 9.8 (March 23, 2001) (C) 2001 Monty and Xiphophorus Report bugs to paranoia@xiph.org http://www.xiph.org/paranoia/ Checking /dev/sr0 for cdrom...

Hello, You need to change the permissions for the program cdparanoia. I believe that it is in the /usr/bin directory. I had to set it suid root in order for me to get it to work but I'm sure others on this list can probably tell you how to get it to work without doing it suid root. -- Marshall "Nothing is impossible, We just do not have all the anwsers to make the impossible, possible."

This is a issue that I would like the LINUX community to address. It deals with permissions on a ide-scsi device. (At least in SuSE 7.3 and 8.0) 1. It is a bad idea to be in "Root" for both error (rm -r *) and security reasons. It is safer to run programs as a "User". Besides many XDM/GDM/KDM login screens offer logins as a "User". Then why is it that programs like Xcdroast fail while being a "User" because the /dev/sr0 is only available to "Root". The ide-scsi device is set to be used by Root but the program Xcdroast complains about executing as "Root". However, Xcdroast refuses to come up as a "User" because the "User" doesn't have permission to use the /dev/sr0. This can be fixed by changing the permissions but why is it set that way at all. There needs to be a meeting of the minds between security and the common sense folks. -- 73 de Donn Washburn __ " http://www.hal-pc.org/~dwash " Ham Callsign N5XWB / / __ __ __ __ __ __ __ 307 Savoy St. / /__ / / / \/ / / /_/ / \ \/ / Sugar Land, TX 77478 /_____/ /_/ /_/\__/ /_____/ /_/\_\ LL# 1.281.242.3256 a MSDOS Virus "Free Zone" OS Email: n5xwb@arrl.net Info: http://www.austinlug.org
