Quoting serge delorme ([EMAIL PROTECTED]): CD-burning packages are not installed yet, I was just testing the drive after recompiling the kernel.

I can read a data-cd and play a music-cd, but I don't understand why I can now and not yesterday. Is there something in the start-up scripts of cron that could do it? Thats the only stuff that ran since yesterday... Usually this is because you . try it and fail with permission denied . login as root and add yourself to the group . try it again (perhaps even recalling the old command) and fail with permission denied . logout or reboot . try it and it works You have to login *after* adding yourself to the group.

lost access to cdrom
I changed my cdrom drive for a cd-rw, recompiled the kernel for scsi-emulation, linked the new device with /dev/cdrom. At boot-up: SCSI subsystem driver Revision: 1.00 scsi0 : SCSI host adapter emulation for IDE ATAPI devices Vendor: SONY Model: CD-RW CRX160ERev: 1.0e Type: CD-ROM ANSI SCSI revision: 02 Detected scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0 sr0: scsi3-mmc drive: 32x/32x writer cd/rw xa/form2 cdda tray Uniform CD-ROM driver Revision: 3.12 Mounting the drive: /dev/scd0 on /cdrom type iso9660 (ro,noexec,nosuid,nodev,user=sdelorme) As root it's ok but as user I can't access the drive even if: [EMAIL PROTECTED]:~$ ll /dev/scd0 brw-rw2 root cdrom 11, 0 jui 5 2000 /dev/scd0 [EMAIL PROTECTED]:~$ ll /dev/cdrom lrwxrwxrwx1 root root9 jan 28 14:04 /dev/cdrom - /dev/scd0 [EMAIL PROTECTED]:~$ groups sdelorme adm disk dialout cdrom floppy audio dip I'm lost. -- Serge Delorme [EMAIL PROTECTED] Un autre utilisateur GNU/DEBIAN
