Trying to write a php page that has a form that lets you type in a remote IP or Hostname, and retrieve basic info like RAM Size and HD size.

The code that processess the form data:

   $host = $_POST['host'];
   $cmd = "cscript /nologo remotehostinfo.vbs ".$host;
   $output = shell_exec($cmd);
   echo "<pre>$output</pre>";

This is the remotehostinfo.vbs code, the script does a WMI query to a remote host.

DIM arg
Set arg = wscript.Arguments
strComputer = arg(0)
On Error Resume Next
wscript.echo "Info"
wscript.echo "------"
'//////// Get Ram Amount
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
Set colCSItems = objWMIService.ExecQuery("SELECT * FROM Win32_ComputerSystem")
For Each objCSItem In colCSItems
  ram = int(objCSItem.TotalPhysicalMemory/ 1048576)
Next
wscript.echo "RAM Size: " & ram
wscript.quit

When I run the script from the PHP page, it does not return the RAM size, but if I run the vb script from a command prompt it works just fine, anyone know what I'm doing wrong? Can PHP not run a vbscript that does a query of a remote host?

Does your command include the `> test.txt` when ran on the command line? Your script now writes the output to `text.txt` so you might aswell try to read that file using PHP. – Devator Feb 08 '13 at 16:01

Perhaps you should supply the full path to `cscript`. – flowfree Feb 08 '13 at 16:01
@devator, sorry, forgot to remove that. It no longer includes that. – DobotJr Feb 08 '13 at 16:01
@bdsnoobs, the script runs. Otherwise I would get a "Could not find the file" error. – DobotJr Feb 08 '13 at 16:02
Also, make sure you escape the shell arguments! http://php.net/manual/en/function.escapeshellarg.php – Martin Samson Feb 08 '13 at 16:09
@MartinSamson I will, as soon I can get this to work. – DobotJr Feb 08 '13 at 16:12
