You seem to be under the impression that sudo is all-or-nothing. |
| 15 |
There is a safe compromise. You can specify which commands, with which |
| 16 |
parameters, are runnable as toot by which user. E.g. my desktop is |
| 17 |
"d531" and my regular user ID is "waltdnes". I have file |
| 18 |
/etc/sudoers.d/001 containing stuff like... |
| 19 |
|
| 20 |
waltdnes d531 = (root) NOPASSWD: /sbin/hwclock --systohc |
| 21 |
waltdnes d531 = (root) NOPASSWD: /usr/bin/openrdate -n -s ca.pool.ntp.org |
| 22 |
|
| 23 |
...and I have a script ~/bin/settime |
| 24 |
|
| 25 |
#!/bin/bash |
| 26 |
/usr/bin/sudo /usr/bin/openrdate -n -s ca.pool.ntp.org |
| 27 |
/usr/bin/sudo /sbin/hwclock --systohc |
| 28 |
|
| 29 |
...which sets my clock. You would want... |
| 30 |
|
| 31 |
userid machine_name = (root) NOPASSWD: /sbin/shutdown -a -h now |
| 32 |
|
| 33 |
...in /etc/sudoers.d/001 |
| 34 |
|
| 35 |
*NOTE*. Use "visudo" to edit any sudoers file. Do not edit directly |
| 36 |
with vim/nano/emacs/etc. "man visudo" for further details. |
