Ruby ssh錯誤Net :: SSH :: AuthenticationFailed雖然它與PHP一起工作

我試圖通過SSH使用Ruby連接服務器，但是我有Net :: SSH :: AuthenticationFailed錯誤。問題是它在PHP中起作用。Ruby ssh錯誤Net :: SSH :: AuthenticationFailed雖然它與PHP一起工作

這裏是我的Ruby代碼：

require 'rubygems' 
require 'net/ssh' 
include Net 
domain = 'ks2.so.d-sites.com' # insert IP address or domain name here 
begin 
Net::SSH.start(domain, 'webistrano', :verbose => :debug, :keys => ['/home/webistrano/.ssh/id_rsa', '/home/webistrano/.ssh/id_rsa.pub'], :port => 22) do |ssh| 
print "connected" 
end 
rescue Net::SSH::HostKeyMismatch => e 
    puts "remembering new key: #{e.fingerprint}" 
    e.remember_host! 
    retry 
end

我得到這個錯誤：

    from ssh-test.rb:6

我寫了一個簡單的PHP代碼，它的工作原理：

<?php 
$connection = ssh2_connect('ks2.so.d-sites.com', 22); 

if (ssh2_auth_pubkey_file($connection, 'webistrano', 
          '/home/webistrano/.ssh/id_rsa.pub', 
          '/home/webistrano/.ssh/id_rsa')) { 
    echo "Identification réussie en utilisant une clé publique\n"; 
} else { 
    die('Echec de l\'identification en utilisant une clé publique'); 
}

是否有某人那可以幫助我？非常感謝！

我發現如何解決該問題：在Net::SSH.start函數中添加:auth_methods => ['publickey','password']參數。

結帳也'：non_interactive => true' – nhed 2018-03-09 22:20:54

我沒有使用Net :: SSH.start解決方案，但選擇了set :ssh_options, {:forward_agent => true, :auth_methods => 'publickey'}這似乎在我的工作。注意到最初，我只是在運行在FreeBSD，CentOS和MacOSX上的3臺機器上使用了set：ssh_options，{:forward_agent => true}，它運行良好 - 甚至在生產版本上使用，但是在基於VBoxed的基於Vagrant的CentOS（6.4）機器停止工作。所以，添加auth_method的確有竅門。

我以前見過這個錯誤，請嘗試卸載寶石的淨-SSH「，試試這個：寶石卸載網的ssh -v 2.8.0，它爲我工作，參考：https://stackoverflow.com/a/21566548/3159604
