% Hi List
Hi!
%
% I've gone through the list for previous questions and the only one that
% seems to be a solution is to use sudo, however, I cannot seem to get it
% right.
...
%
% Obviously these command(s) need to be run as root, so I looked at the
% /etc/sudoers and added apache , BUT, in the error log it prompts for a
% password.
1) Are you sure your web server is running as apache? If not, run
something like
passthru("/usr/bin/id") ;
(or wherever your id program is) in a php page (easier than redirecting
to a file :-) and see what it tells you.
%
% I tried to add the option NOPASSWD: ALL to the file, but it says there's
% a syntax error.
Your line should look about like
admind ALL = (ALL) NOPASSWD: /path/to/reboot
where "admind" is the name under which your web server runs. In fact, it
should probably look more like
admind hostname = (root) NOPASSWD: /path/to/reboot
to allow admind to run reboot as root on machine "hostname".
Have you read the man page for sudoers? Yes, it's a bit thick, but it
absolutely covers everything you need to know :-)
%
% What am I missing?
Since you haven't shown us your attempt, it's tough to answer that other
than to note that you're at least missing showing what you tried!
%
% Any other ways of doing this? PS, I don't even want to consider Webmin,
% it's way too complicated, I just want a handfull of predefined commands
% to be run, nothing else)
sudo is *definitely* your best approach. It really is. It's easy, too,
I promise.

Re: [PHP] reboot pc with PHP
of course, i've only just seen that the script removes it. it's been a long
day, my apologies.
just out of curiosity, why would you want the ability to reboot your box
like that?

RE: [PHP] reboot pc with PHP
Exactly ..
Well, the script removes the rreboot file before the shutdown.
For security choose a directory for rreboot file placed in a directory that only can
be readed/writed by apache, and the php file in the example its very simple, but you
can ask for a password, create a log, etc ..
chown 700 /directory/for/rrebootfile
chown apache.nobody /directory/for/rrebootfile

just one little point (i'm glad i don't have to give a setuid lecture) personally
i would make sure that the location of the check file is extremely secure.
under normal circumstances, any user could write the rreboot file and cause a reboot
also, remember to remove the file again in rc.local before cron starts etc.
but i like the idea. its much more secure (from a web perspective).

RE: [PHP] reboot pc with PHP
A more easy solution is that: Make a cron that executes every minut /tmp/rreboot.sh for user root crontab -e Add the line: * * * * * /tmp/rreboot.sh The script is: /tmp/rreboot.sh --- #!/bin/sh if [ -f "/tmp/rreboot" ]; then rm -f /tmp/rreboot shutdown -r now fi --- Make executable the file with chmod +x /tmp/rreboot.sh And a simple PHP like: /tmp/rreboot"); echo "Ok, i'll reboot in a few seconds"; ?> So, when anyone calls to this PHP, creates a file, that if its detected by rreboot.sh, the root will reboot the machine. -Mensaje original- De: Javier Tacon Enviado el: jueves, 28 de agosto de 2003 15:07 Para: Petre Agenbag; [EMAIL PROTECTED] Asunto: RE: [PHP] reboot pc with PHP You can write a little script with expect (man expect) and execute it from php with exec().
