7 Firstly "grep -i uncomment /etc/sudoers" results in...
9 ## Uncomment to enable special input methods. Care should be taken as
10 ## Uncomment to use a hard-coded PATH instead of the user's to find commands
11 ## Uncomment to send mail if the user does not enter the correct password.
12 ## Uncomment to enable logging of a command's output, except for
13 ## Uncomment to allow members of group wheel to execute any command
14 ## Uncomment to allow members of group sudo to execute any command
15 ## Uncomment to allow any user to run sudo if they know the password
17 ...I.e. the file is explicitly telling you to edit it if required!!!

21 My regular user has script "settime" in ${HOME}/bin
23 #!/bin/bash
24 date
25 /usr/bin/sudo /usr/bin/rdate -nsv
26 /usr/bin/sudo /sbin/hwclock --systohc
27 date
29 /etc/sudoers.d/001 has, amongst other things, two lines...
31 waltdnes x8940 = (root) NOPASSWD: /sbin/hwclock --systohc
32 waltdnes x8940 = (root) NOPASSWD: /usr/bin/rdate -nsv
34 User "waltdnes" is a member of "wheel". If the "wheel" line is
35 uncommented in /etc/sudoers, sudo works for me. If the "wheel" line is
36 commented, then sudo breaks for my regular user.

47 Me too.
49 There seem to be two different approaches here. The loose approach is
50 to allow a user to run "sudo <whatever I damn well want>". A more locked
51 down approach allows regular users to run "sudo <very specific command>".
52 This guards against "fat-finger-syndrome". I go with the more locked
53 down approach

56 I've seen things, you people wouldn't believe; Gopher, Netscape with
57 frames, the first Browser Wars. Searching for pages with AltaVista,
58 pop-up windows self-replicating, trying to uninstall RealPlayer. All
59 those moments, will be lost in time like tears in rain... time to die.
