2 options: |
| 15 |
|
| 16 |
1. Sudo can be setup to allow some commands to be run without a |
| 17 |
password. I think this entry in /etc/sudoers should work: |
| 18 |
|
| 19 |
mythtv ALL = NOPASSWD: /sbin/shutdown |
| 20 |
|
| 21 |
I have not tested this, so if something goes wrong, you'll have to try |
| 22 |
and figure out "man sudoers". |
| 23 |
|
| 24 |
2. Create a setuid (chmod 4711 /sbin/shutdown_by_anyone.sh) shell script |
| 25 |
that runs shutdown. Be sure to export the PATH, and unset LD_PRELOAD |
| 26 |
and LD_LIBRARY_PATH variables at the very beginning of the script. Also |
| 27 |
make sure the interpreter line is "/bin/bash --". This doesn't fix all |
| 28 |
of the security holes with setuid shell scripts, just the most common |
| 29 |
and easiest to fix... |
