Scenario
You have a Powerware (might work with other software) UPS that powers more than 1 PC but has limited Software, like Powerware's on Ubuntu for example.
This is where some SSH and PHP comes handy .. this is how I fixed it :
Somewhere on your server .. create a .htpasswd file :
mine is /home/yancho/.htpasswd by
Quote:
htpasswd -bc NAME username password
Somewhere else in your server .. create a PHP file .. find its directory and then in ur apache config do this :
Quote:
<Directory "/home/yancho/public_html/blabla/abc">
AuthType Basic
AuthName "Authentication Required"
AuthUserFile "/home/yancho/.htpasswd"
Require valid-user
Order Deny,Allow
Deny from all
Allow from 10.0.0.1
</Directory>
The PHP file i created is turnoff.php .. in it there is just these lines:
Code:
<?
echo "Shutting down the Ubuntu Server<br>";
$result = shell_exec('sudo /home/yancho/turnoff.sh');
echo $result;
?>
Ok now we create the turnoff.sh
Code:
#!/bin/bash
echo "Powering off the machine"
sudo shutdown -h now
Save and chmod +x turnoff.sh
Now we need to give the www-data which is the username Apache with PHP is running . .check urs by echoing from PHP script - using :
[php:1:76799d917d]
shell_exec('whoami');
[/php:1:76799d917d]
