problemas de permisos
buenas...
tengo varios problemas con ¿permisos? a ver si alguien me puede orientar:
a) quiero que cualquier usuario pueda escribir en una particion de
win, y no quiero que los 'ls' salgan todos verdes (o sea, marcados
como ejecutables), la linea en mi /etc/fstab es así:
/dev/hda1 /mnt/winchoto vfat auto,users,showexec,umask=022 0 0
pero no puedo escribir nada cuando queda montada en el inicio, si
intento desmontar y montar de nuevo como un usuario comun puedo
escribir perfectamente ¿alguna idea?
b) para grabar cd con el cdrecord tampoco me deja, le dije al
dpkg-reconfigure que si instale como suid y todo eso pero no me deja,
les muestro una salida como usuario comun y como root para que alguien
pueda sacar algo en limpio porque a mi me supera

la única diferencia que vi es que dice que "cdrecord.mmap: Cannot init
drive", los permisos para cdrecord están:
root@CCCP:/home/sfish# ls -lh /usr/bin/cdrecord*
-rwsr-xr-x 1 root root 142 2003-09-12 13:17 /usr/bin/cdrecord
-rwsr-xr-- 1 root cdrom 335K 2003-09-12 13:17 /usr/bin/cdrecord.mmap
-rwsr-xr-- 1 root cdrom 335K 2003-09-12 13:17 /usr/bin/cdrecord.shm
y el grupo cdrom dice que si pertenesco a ese grupo:
root@CCCP:/home/sfish# grep cdrom /etc/group
cdrom:x:24:sfish,hal
¿ideas?
