PHP SSH2问题ssh2_connect [英] PHP SSH2 Problem ssh2_connect

问题描述

所以我从php.net上看了一个例子看php ssh2的工作原理



所以代码是

 <？php  
  $ connection  = ssh2_connect（'  shell.example.com'，22）; 
 
  if （ssh2_auth_password（$ connection，'  username'，'  secret'））{
 < span class =code-keyword> echo   验证成功！\ n ; 
}  else  {
 die（' 身份验证失败......'）; 
} 
 ？>  

我提供了错误的信息，它给了我一些错误，而不是告诉我身份验证失败。



错误是

警告：ssh2_connect（）：php_network_getaddresses：getaddrinfo failed：名称或 service  not 已知  
 /var/zpanel/hostdata/zadmin/public_html/whothehellcareswhatisthis/ssh2.php  2 警告：ssh2_connect（）：无法连接到

解决方案

连接 = ssh2_connect（' shell.example.com'，22）;

if （ssh2_auth_password（

connection，' 用户名'，' secret'））{
echo 认证成功\\\
！;
} else {
die（' 身份验证失败......'）;
}

So I have taken a example from php.net to see php ssh2 workings

so the code is

<?php
$connection = ssh2_connect('shell.example.com', 22);

if (ssh2_auth_password($connection, 'username', 'secret')) {
    echo "Authentication Successful!\n";
} else {
    die('Authentication Failed...');
}
?>

When I am putting wrong information it is giving me some error instead of telling me Authentication Failed.

The Error is

Warning: ssh2_connect(): php_network_getaddresses: getaddrinfo failed: Name or service not known in 
/var/zpanel/hostdata/zadmin/public_html/whothehellcareswhatisthis/ssh2.php on line 2 Warning: ssh2_connect(): Unable to connect to

on line 4 Authentication Failed...

解决方案

connection = ssh2_connect('shell.example.com', 22); if (ssh2_auth_password(

connection, 'username', 'secret')) { echo "Authentication Successful!\n"; } else { die('Authentication Failed...'); } ?>
