Net :: SSH.start超时连接到Ruby中的Vagrant主机

问题描述：

我有一个vagrant VM正在运行。Net :: SSH.start超时连接到Ruby中的Vagrant主机

vagrant init centos/7

产生最小Vagrantfile：

Vagrant.configure(2) do |config| 
    config.vm.box = "centos/7" 
end

vagrant ssh-config报告如下：

Host default 
    HostName 127.0.0.1 
    User vagrant 
    Port 2222 
    UserKnownHostsFile /dev/null 
    StrictHostKeyChecking no 
    PasswordAuthentication no 
    IdentityFile "/path/to/.vagrant/machines/default/virtualbox/private_key" 
    IdentitiesOnly yes 
    LogLevel FATAL

但是，下面好像失败：

require 'net/ssh' 
Net::SSH.start("127.0.0.1", "vagrant", { 
    :auth_methods => [ 
     "publickey", 
     "password" 
    ], 
    :port=>"2222", 
    :keys => [ 
     "/path/to/.vagrant/machines/default/virtualbox/private_key" 
    ] 
})

w ^第i个以下：

Net::SSH::ConnectionTimeout: Net::SSH::ConnectionTimeout 
    from /usr/local/lib/ruby/gems/2.4.0/gems/net-ssh-4.1.0/lib/net/ssh/transport/session.rb:90:in `rescue in initialize' 
    from /usr/local/lib/ruby/gems/2.4.0/gems/net-ssh-4.1.0/lib/net/ssh/transport/session.rb:57:in `initialize' 
    from /usr/local/lib/ruby/gems/2.4.0/gems/net-ssh-4.1.0/lib/net/ssh.rb:233:in `new' 
    from /usr/local/lib/ruby/gems/2.4.0/gems/net-ssh-4.1.0/lib/net/ssh.rb:233:in `start' 
    from (irb):2 
    from /usr/local/bin/irb:11:in `<main>'

我可以使用SSH连接，符合市场预期：

ssh -p 2222 -i /path/to/.vagrant/machines/default/virtualbox/private_key [email protected]

我怎样才能连接到在Ruby中vagrant主机我的本地机器上？

答

这不是一个答案，但它值得被添加到线程，努力帮助...

如果有这个确切的问题Chef和Ruby本地机器上的VBox所以首先知道你并不孤单。它似乎并不与基础Ruby框架的问题，你可以测试：

注意你需要调整IP &用户

#!/usr/bin/env ruby 

require 'net/ssh' 

puts "opening connection.\n" 
new_connection = Net::SSH.start('192.168.1.116', 'root', {:keys => ['~/.ssh/id_rsa'], :keepalive => true, :keepalive_interval => 60, :timeout => 60}) 
puts "connection established, run uptime.\n" 
puts new_connection.exec!('uptime') 
puts "running uname -a\n" 
puts new_connection.exec!('uname -a') 
puts "sleeping for 300 seconds.\n" 
(1..5).each do |iterator| 
    sleep_seconds = iterator * 60 
    sleep 60 
    puts "#{sleep_seconds}\n" 
end 
puts "running uptime.\n" 
puts new_connection.exec!('uptime') 
puts "running uname -a\n" 
puts new_connection.exec!('uname -a') 
puts "closing connection.\n" 
new_connection.close 
puts "done.\n"

然后执行：ruby ./test.rb

的Chef失败有一个非常类似的输出到你自己的和注意相同的版本：
