SSH script to collect system information is not working after one statement

bentech4u

HI everyone,

i am a php beginner trying to generate one script for taking system information. Line "zonecfg.." i added recently and when i run the script, the page is waiting ..

<?php
$zonename = array();
$index = 0;
$connection = ssh2_connect('172.16.101.80', 22, array('hostkey'=>'ssh-rsa'));

if (ssh2_auth_pubkey_file($connection, 'root',
                          '/var/www/html/ssh/id_rsa.pub',
                          '/var/www/html/ssh/id_rsa', 'secret')) {
  //echo "Public Key Authentication Successful\n";
} else {
  die('Public Key Authentication Failed');
}

if($output = ssh2_exec($connection, 'zoneadm list -cv ')) {
    stream_set_blocking($output, true);

$result= stream_get_contents($output);
$resultArray = preg_split('/[\s]+/',ltrim($result));
$rows = array_chunk($resultArray,6);
$columns = array_shift($rows);
$data = array();

foreach ($rows as $row) {
$q = array_combine($columns, $row);

if($q['NAME']=="global"){
    if($globalNameStream = ssh2_exec($connection, 'hostname')){
       stream_set_blocking($globalNameStream,true);
       $q['NAME'] = stream_get_contents($globalNameStream);
    }
}else{
    echo $data[$index]['NAME'];
    echo "<br/>";
    $index++;
    if($IpNameStream = ssh2_exec($connection,"zonecfg -z". $data[$index]['NAME']  ." info | grep address  | awk '{print $2}'")){
    stream_set_blocking($IpNameStream,true);
    $q['IP'] = stream_get_contents($IpNameStream);
}}
$data[] = $q;
}

print_r($data);
echo "<br/>";
}
?>

on this above code, $data[index]['NAME'] is not accepting and the page hangs always. ig i gave the value insted of this variable, it;s giving output

please anyone help me to fic this

You may be a beginner at PHP, but this isn't "beginner level" IT work.

<?php
$zonename = array();
$index = 0;
$connection = ssh2_connect('172.16.101.80', 22, array('hostkey'=>'ssh-rsa'));

if (ssh2_auth_pubkey_file($connection, 'root',
                          '/var/www/html/ssh/id_rsa.pub',
                          '/var/www/html/ssh/id_rsa', 'secret')) {
  //echo "Public Key Authentication Successful\n";

Is this a Linux box? Let me give you a hint on how to walk more safely through the neighborhood at night:

http://www.howtogeek.com/howto/linux/security-tip-disable-root-ssh-login-on-linux/

} else {
  die('Public Key Authentication Failed');
}

if($output = ssh2_exec($connection, 'zoneadm list -cv ')) {
    stream_set_blocking($output, true);

$result= stream_get_contents($output);

It's not clear to me from the docs ... does ssh2_exec even return a stream? I don't think so...

    $resultArray = preg_split('/[\s]+/',ltrim($result));
    $rows = array_chunk($resultArray,6);
    $columns = array_shift($rows);
    $data = array();

foreach ($rows as $row) {
$q = array_combine($columns, $row);

if($q['NAME']=="global"){
    if($globalNameStream = ssh2_exec($connection, 'hostname')){
       stream_set_blocking($globalNameStream,true);
       $q['NAME'] = stream_get_contents($globalNameStream);
    }
}else{
    echo $data[$index]['NAME'];
    echo "<br/>";
    $index++;
    if($IpNameStream = ssh2_exec($connection,"zonecfg -z". $data[$index]['NAME']  ." info | grep address  | awk '{print $2}'")){
    stream_set_blocking($IpNameStream,true);
    $q['IP'] = stream_get_contents($IpNameStream);
}}
$data[] = $q;
}

print_r($data);
echo "<br/>";
}
?>

on this above code, $data[index]['NAME'] is not accepting and the page hangs always. ig i gave the value insted of this variable, it;s giving output

I'm not sure I understand your comment "$data[index]['NAME'] is not accepting" ... it has no value?

And welcome to PHPBuilder and all. However, a word to the wise; it's easier for people to help you if you type your posts a bit more carefully. 😉

(I do understand being tired and stuff, and have occasionally had drunken monkeys type on my keyboard while I was on a restroom break 😉 )

thanks for the replay. first part of the code is giving right answers, when i add zonecfg..etc to the code only this issue got happend. when i change the machine $data[index]['NAME'] with proper name (example.com), it's giving me the IP address. that means ssh2 command is not accepting variable or not.?

don't know as a beginner, i don;t know how to search and get proper examples of php

yea this script is installed on linux box and the clients are solaris, so this linux box is acting as jumbox and the pub key for root is installed on all the other 250 machines

OK, here:

$data = array();

you initialize an empty array.

At what point does it get populated?

bentech4u

yes $data array is there.

Where? As I showed, in your example you create an empty array and then call data from it without showing any operation that would populate the array....

I apologize if it seems I am being harsh. Is English not your primary language? Ben is, typically, an English name.

It's OK if it's not your primary language, we can work on that; but you really should try harder to answer the questions you are getting about your problem if you want help here.

i don't know more about array process and all

 echo $data[$index]['NAME'];
        echo "<br/>";
        $index++;
        if($IpNameStream = ssh2_exec($connection,"zonecfg -z".$q[$index]['NAME'] ."| grep address  | awk '{print $2}'")){
        stream_set_blocking($IpNameStream,true);
        $q['IP'] = stream_get_contents($IpNameStream);

echo $data[$index]['NAME'] is printing all the name but IP is not showing printing

now i have changed my code like below:

<?php
$zonename = array();
$index = 0;
$connection = ssh2_connect('172.16.101.80', 22, array('hostkey'=>'ssh-rsa'));

if (ssh2_auth_pubkey_file($connection, 'root',
                          '/var/www/html/ssh/id_rsa.pub',
                          '/var/www/html/ssh/id_rsa', 'secret')) {
  //echo "Public Key Authentication Successful\n";
} else {
  die('Public Key Authentication Failed');
}

if($output = ssh2_exec($connection, 'zoneadm list -cv ')) {
    stream_set_blocking($output, true);

$result= stream_get_contents($output);
$resultArray = preg_split('/[\s]+/',ltrim($result));
$rows = array_chunk($resultArray,6);
$columns = array_shift($rows);
$data = array();

foreach ($rows as $row) {
$q = array_combine($columns, $row);

if($q['NAME']=="global"){
    if($globalNameStream = ssh2_exec($connection, 'hostname')){
       stream_set_blocking($globalNameStream,true);
       $q['NAME'] = stream_get_contents($globalNameStream);
    }
}else{
    echo $q['NAME'];
    echo "<br/>";
    //$index++;
    if($IpNameStream = ssh2_exec($connection,"zonecfg -z".$q['NAME'] ."| grep address  | awk '{print $2}'")){
    stream_set_blocking($IpNameStream,true);
    $q['IP'] = stream_get_contents($IpNameStream);
}}
$data[] = $q;
}

print_r($data);
echo "<br/>";
}
 ?>

is that correct?
