Question

I am using phpseclib in my project. I have installed it and am testing it using the following piece of code which is similar to the example here.

Updated Code:

1           require("Net/SSH2.php");
2   
3           if (!class_exists('Net_SSH2')) die("Class Net_SSH2 doesn't exist!");
4           
5           $ssh = new Net_SSH2('***');   // the host IP address 
6           
7           if (!method_exists($ssh, 'Net_SSH2')) die("Net_SSH2 class doesn't have Net_SSH2 method!");
8    
9           if (!$ssh->login('***', '***')) {   // (verified) username and password
10              echo "LOG: " . $ssh->getLog() . "<br>";
11              exit('Login failed!');
12          }

Code Update 2:

1       require("Net/SSH2.php");
2
3       define('NET_SSH2_LOGGING', NET_SSH2_LOG_COMPLEX);
4
5       if (!class_exists('Net_SSH2')) die("Class Net_SSH2 doesn't exist!");
6       
7       $ssh = new Net_SSH2('***');   // the host IP address 
8       
9       if (!method_exists($ssh, 'Net_SSH2')) die("Net_SSH2 class doesn't have Net_SSH2 method!");
10
11      if (!$ssh->login('***', '***')) {   // (verified) username and password
12          echo "LOG: " . $ssh->getLog() . "<br>";
13          echo "ALL ERRORS: ";
14          print_r($ssh->getErrors());
15          echo "<br>LAST ERROR: " . $ssh->getLastError() . "<br>";
16          exit('Login failed!');
17      }

It exits at line # 16. getLog() gives nothing so it is hard to know where the problem is. I had the login credentials tested using PuTTY. It is not able to login to other servers either. I am not able to understand what is causing the problem.

Any help would be highly appreciated!

Answer 1

I ended up hosting my code on the server (server B) that I was trying to connect. The same code worked in the opposite direction (I could connect to the server A where my code previously was)! I ended up concluding that the server A has environmental issues.
I appreciate those were helping me here!
