It's fine to continue it here, so the folks on the list can (hopefully!) see the answer. > >On Wed, Feb 02, 2000 at 15:59:00 -0500, Jim C wrote: > > > (hist 503)# ls -al /dev/pas* > > > crw------- 1 root operator 31, 0 Dec 23 11:43 /dev/pass0 > > > crw------- 1 root operator 31, 1 Dec 23 11:43 /dev/pass1 > > > crw------- 1 root operator 31, 2 Dec 23 11:43 /dev/pass2 > > > crw------- 1 root operator 31, 3 Dec 23 11:43 /dev/pass3 > > > >Are you running as root or not?

You can't access the passthrough device with a securelevel greater than 1, since it allows nasty things to happen. (e.g. you can format disks, write to random sectors, etc.) I should have noticed that camcontrol and cdrecord were returning "operation not permitted" instead of "permission denied". (The pass(4) driver returns EPERM when the securelevel is > 1.)
