SSH2 run commands on a router

[Noodle2732]

Hi there,

 

I am trying to use the SSH2 extension of PHP to run a command on a Draytek router.  If i use putty or just ssh from the cli i can login browse the menu, run commands and exit.

 

I am trying just to pull the status of the router off of it.

the command is 'system status' and as i say running this in a normal ssh client works fine.

 

In PHP however.....

The first issue is that it takes forever to actually make the connection and run the command, i will be sitting there looking at the loading icon for 5 - 10 mins before i get any output.  The second issue is that it sends the command too early i think. I'm not sure.

 

Here is my code:

if (!function_exists("ssh2_connect")) die("ERROR: The ssh2_connect function is not available.\n Is the SSH2 extension installed correctly?");
// log onto the SSH server
if(!($con = ssh2_connect('10.0.1.254', 8022))){
    	die ("ERROR: Unable to connect to SSH server!");
} else {
    	// try to authenticate the open SSH connection
    	if(!ssh2_auth_password($con, "draytek", "Password")) {
        	die ("ERROR: Unable to authenticate!");
    	} else {
        	echo "Logged into SSH server!\n";
        
        	// create a shell
        	if(!($shell = ssh2_shell($con, 'xterm'))){
            	die("ERROR: Failed requesting an interactive shell");
        	} else{
        		//Make sure that the stream receives data back before requesting it.
            	stream_set_blocking( $shell, true );
            	// send a command 
            	fwrite($shell,'system status');
			            
            	// Collect & display returning data
			echo "<pre>";
            	while( $buf = fgets($shell) ){
                	echo $buf;
            	}
			echo "</pre>";
            	fclose($shell);
        	}
    	}
}

The output is:

Logged into SSH server!

system statusLogin by remote client
DrayTek> 

 

in a normal ssh client this is the output:

login as: draytek
[email protected]'s password:
Login by remote client
DrayTek> system status

btw if i connect to the webserver as an ssh server i.e. conenct to 127.0.0.1 i can run commands and get results back with no issues.

 

Thanks in advance, Nathan
