Hi All,
sometimes I load a scsi cd-rw at boot. It's always loaded as /dev/hdc.
I have a coupla Qs about permissions etc. When it's loaded each time,
does the file /dev/hdc permissions get altered each time.? I ask this,
because, 2 dys ago, I changed the permissions of the file to 666, so
as to allow K3b to burn in root mode. This is because the burn process
stops mid burn with a 254 error stating cdrecord is not being run with
root priviliges. But, the permissions are back as 600 today. I would
have thought the file's permissions stay changed despite the loading
or not of a block device to that file.? Am I wrong..?
Hi All,
just to delve into this a little more; what are the default udev
permissions/ownership for /dev/hdc /dev/scd0.? I get the following,
[root localhost dev]# ls -alh hdc scd0
brw------- 1 coolboarderguy disk 22, 0 Mar 9 2005 hdc
brw------- 1 coolboarderguy disk 11, 0 Mar 9 2005 scd0
Shouldn't they be owned by root..? If no, then I get problems with
cdrecorder/K3b. Burning stops mid-burn and gives the 254 error saying
that cdrecorder is not with root priviliges. Little confused. Cheers.
You'll find there's a symlink created by udev:
/dev/cdwriter -> hdc
The device pointed to by this symlink will be owned by the currently-
logged-in user, so that they can access the device.
See /etc/security/console.perms
The idea is to support cd burning as a non-root user, but it appears
that this isn't working...
