Not by a GUI but by shell scripts, i frequently use cdrecord as non-root. Setuid bit does work for me (Linux kernels 2.0 to 2.4, cdrecord 1.6 to 2.01). The superuser once applied : cdrecord_address=...insert.address.here... chown root $cdrecord_address chmod a+x,go-w,u+s $cdrecord_address Ownership and permissions now look like : -rwsr-xr-x 1 root root What can have gone wrong ? - the GUI program got its own ideas what cdrecord to use ? ( try cdrecord standalone ) - your attempts to set owner and permissions did not take effect ? ( ls -l ) - you treated the wrong file ? ( find / -name cdrecord -print 2>/dev/null ) - your system refuses to perform setuid ? ( try out with own code ) - ( room for more ideas ) Disclaimer : Skilled local users might try to exploit the security problems of setuid. sudo would be better but -to my knowledge- demands some kind of skilled sysadmin during setup. Also the application would have to call sudo rather than cdrecord. Preferable if achievable. Have a nice day :) Thomas
