CMD and PHP...

zingbats

I want to make a PHP and HTML script that can send a command to CMD.

Basically, you have a form that contains two boxes one called "computer" and one called "message"

When you hit the button, it sends you to... C:\WINDOWS\system32\cmd.exe It ALSO sends the command "net send $computer $message" Allowing messages to be sent.

Please help me

Alex.

this may get you going in the right direction

<?
$path = 'c:\winnt\system32\net send ';
$ip = "computername";
$msg = "hey i see you";
$fullmsg = $path . $ip . " " . $msg; 
$go = shell_exec( $fullmsg );
?>

I get the error:

Warning: Cannot execute using backquotes in safe mode in /PATH/ on line 6

Can it only be done if PHP is not in safemode?

Try using addslashes() on $fullmsg. He handled it with single quotes the first time, which made the "\n" not parsed as a return, but when all are combined into $fullmsg, I believe it lost that status, and became a return.

stolzyboy

or just do it this way, mordecai was right, just make all the double quotes single quotes

<?
$path = 'c:\winnt\system32\net send ';
$ip = computername;
$msg = 'hey i see you';
$fullmsg = $path . $ip . ' ' . $msg;
echo $fullmsg;
$go = shell_exec( $fullmsg );
?>

I still get that error.

How could I implement the addslashes() thingy ma jig?

NOTE: I have a unix server. Will that prevent it from doing it correctly? - Also, is that the correct path, or do I actually have to enter the full path (I know it sounds stupid....)

<?
$path = 'c:winntsystem32\net send';
$ip = 'computername';
$msg = 'hey i see you';
$fullmsg = $path . $ip . ' ' . $msg; 
$go = shell_exec( $fullmsg );
?>

looks like the forum has been taking out my backslashes so the code wasn't showing up correctly, and no you can't use net send on a unix/linux box, net send is a windows networking thing

<?
$path = 'c:\winnt\system32\net send ';
$ip = 'barracuda';
$msg = 'hey i see you';
$fullmsg = $path . $ip . ' ' . $msg;
echo $fullmsg;
$go = shell_exec( $fullmsg );
?>

No, what I mean is, my server is Unix. But the users' computer will be Windows. 😃

Where you say "'c:\winnt\system32\net send" do you mean the full URL, like C:\WINDOWS\system32\net.exe?

You're setting the path to one which doesn't exist on your unix server, PHP is server side thus the path is realtive to the server.

The easiest way to do it would probably to be use an NT server to run the command (or a spare users machine) assuming this is a project for your local network.

You will need to setup sharing permission for that directory (FAT) so the unix server is able to access it, then just reference the file using its netbios name.

Then add an extra variable - telling the recipient where the message has come from as otherwise it will just give the name of whatever server you have used to run net send.
$name
echo 'You have recieved a message from $name';

etc etc
