Good ! 2) Test with Ubuntu 12.04. Last line in /etc/sudoers : pascal vortex = NOPASSWD: /sbin/shutdown Command at the shell prompt : sudo -k sudo shutdown -r 20 Content of the auth.log file : May 29 17:10:59 vortex sudo: pascal : TTY=pts/0 ; PWD=/home/pascal ; USER=root ; COMMAND=/sbin/shutdown -r 20 The command execute without asking for a password .... Better ! 3) Test with Ubuntu 12.04. Last line in /etc/sudoers : pascal vortex = NOPASSWD: /sbin/shutdown, /usr/bin/cpufreq-set Commands in the cron script : #!/bin/bash sudo /usr/bin/cpufreq-set --cpu 0 --governor powersave sudo /usr/bin/cpufreq-set --cpu 1 --governor powersave Content of the auth.log file : May 29 17:25:01 vortex CRON[11913]: pam_unix(cron:session): session opened for user pascal by (uid=0) May 29 17:25:01 vortex CRON[11912]: pam_unix(cron:session): session opened for user root by (uid=0) May 29 17:25:01 vortex CRON[11912]: pam_unix(cron:session): session closed for user root May 29 17:25:01 vortex sudo: pascal : TTY=unknown ; PWD=/home/pascal ; USER=root ; COMMAND=/usr/bin/cpufreq-set --cpu 0 --governor powersave May 29 17:25:01 vortex sudo: pam_unix(sudo:session): session opened for user root by (uid=1000) May 29 17:25:01 vortex sudo: pam_unix(sudo:session): session closed for user root May 29 17:25:01 vortex sudo: pascal : TTY=unknown ; PWD=/home/pascal ; USER=root ; COMMAND=/usr/bin/cpufreq-set --cpu 1 --governor powersave May 29 17:25:01 vortex sudo: pam_unix(sudo:session): session opened for user root by (uid=1000) May 29 17:25:01 vortex sudo: pam_unix(sudo:session): session closed for user root May 29 17:25:01 vortex CRON[11913]: pam_unix(cron:session): session closed for user pascal The cron script was executed perfectly. So the answer to our complain is : "For Ubuntu 12.04 the rules must be entered at the end of the /etc/sudoers file" Thank's for your help. Now, the question is : "Why, in Ubuntu 12.04, the rules must be entered at the end of the /etc/sudoers file ?" Is it a feature or a bug ???? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/996753 Title: entry in sudoers to execute a script without password prompt as root has no effect since 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sudo/+bug/996753/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
