[SOLVED] Remote Server Access

[ainoy31]

I need to check disk space on a remote server from my web application.  I have tried this piece of code:

 

$access = "ssh user@server-ip-address df -k";

$data = shell_exec($access);

 

If nothing prints out.  I know there is the disk_total_space("/") function but since this is on a remote server.  Much appreciation on any suggestions. AM

You can not do this directly, you need to go by a script on your remote server who retrieves that specific piece of information.

 

On your remote server you put this file:

<?php
print disk_total_space('/');
?>

 

On your server you then do:

<?php
$diskspace = file_get_contents('http://domain/path/to/file/php', 'r'); // assuming your server allows to read remote files
echo $diskspace;
?>

i set this up as a cron job.  such as the following in a php file:

 

$space = shell_exec("ssh (hostname or ip address) df -k | grep sda3 | awk '{print $5}'");

 

this will return the usage in percentage.  Hope this helps someone else out.
