Dear all,
i want to send some unix commands to remote unix machine in france
throughphp.i am using socket communication inphp, i have written a
socket communication program so that it connects to the remote
machine.
i dont get any errors it says socket is connected.i dont know whether
the socket is connected or not.
now i want to send username and password to that remote machine.i am
using socket_send function.
$username='abcd';
$output=socket_send($socket, $username, strLen($username),0);
echo $output;
what ever i send it returns the value integer.for example if i send
$username ='abcd'; then it returns the length as 4,if i send abcde it
returns 5.
I think my username and password is not reaching to the remote machine
when i use socket_send.
can you please give some suggesions

Hi,Shobha,
It's hard to tell with the code you posted. Can you post the real code?
Or, if it's large, cut it down to the bare minimum and post it?

Shobha,

As I said - it depends on what you're trying to do. Post a stripped
down version of your code and we'll take a look at it.

socket_connect($socket,$host,$port) ;

$ser_messegeg=socket_read ($socket, 1024);
echo $ser_messege;
socket_close($socket) ;
}
?>


Please help me

Irfan,

Well, first of all, you need to use the correct port i.e. telnet would be port 23.

Second, I think you mean just send the username and password. You don't send the hostname - you specify it in the socket_connect call.

And when you connect, you should get a prompt to log in. You need to read from the socket to get that prompt, then send your user id to the socket. Wait for the password prompt and send your password. And so on.

Is this clearer?

P.S. Please don't multi-post.
