 |
|
Hello,
is it possible to use cdrecord without suid set and not to get the following warnings?
| Code: |
cdrecord: Operation not permitted. Warning: Cannot raise RLIMIT_MEMLOCK limits.cdrecord: Cannot allocate memory. WARNING: Cannot do mlockall(2).
cdrecord: WARNING: This causes a high risk for buffer underruns.
cdrecord: Operation not permitted. WARNING: Cannot set RR-scheduler
cdrecord: Permission denied. WARNING: Cannot set priority using setpriority().
cdrecord: WARNING: This causes a high risk for buffer underruns.
cdrecord: Permission denied. Cannot open '/dev/hda'. Cannot open or use SCSI driver.
|
To get rid of these warnings, I had to set the suid bit. But I really would prefer to achieve that with normal rights.

suid sounds okay to me...
