Hi,

Read up on PHP socket programming for starters:

http://www.php.net/sockets

Basic idea:

1) PHP connects to router via socket_create()
2) PHP sends username/password via socket_send() and gets the response via socket_read().
3) If we're connected ok, PHP sends the first command via socket_send()
4) PHP reads the router's response via socket_read()
5) If the response looks ok (ie. the router understood the command), we repeat steps 3 and 4 for each new command.
5) When we're done, PHP closes the connection via socket_close()

I'm sure between the scripts you have and the documentation on PHP's website, you'll have no problem accomplishing what you need.

i'm try using this script...and get the result.but the router command are running based on the command that write in the script.how can i make user insert the command for router configuration, example like show run, ping using button?

            //$value1=$_POST['text'];

            $ip=$_POST['ip'];

            $port=$_POST['host'];

    

            $cfgServer = $ip;  //IP of your router

            $cfgPort    = $port;                //port, 22 if SSH

            $cfgTimeOut = 10;

    

            $usenet = fsockopen($cfgServer, $cfgPort, &$errno, &$errstr, $cfgTimeOut);

    

                ?>  <textarea name="output" cols="80" rows="20" class="text1" id="output" readonly="readonly">

     // fputs ($usenet, "conf t\r\n");

     fputs ($usenet, "sh run\r\n");

     fputs ($usenet, " exit\r\n");

    // while (!feof($usenet))

      //  {

        //echo " ".fgets($usenet, 128)."\n";

     //}

        }?>  </textarea>

If you mean "How I can I run a command when a user pushes a button on the page", then you would just use a normal HTML page and in PHP use $_POST to check if the button has been pushed:

PHP Code:

if ($_POST['button1']){
 $command = 'ping';
}else{
 $command = 'foo';
}

 fputs ($usenet, "$command\r\n"); 

If you want it interactive where it stays connected and the user can enter commands (instead of entering 1 command and disconnecting) then you're way out of your league to be honest (and should probably look into having someone write such a solution for you)
