我正在尝试使用knife solo和vagrant来测试厨师食谱。
使用vagrant ssh-config提供的信息，我可以按如下方式连接到我的流浪主机：
ssh -p 3774 -i /path/to/.vagrant/machines/default/virtualbox/private_key vagrant@localhost
我打电话给knife solo：
knife solo prepare -p 3774 -i /path/to/.vagrant/machines/default/virtualbox/private_key vagrant@localhost -VV
引发例外：
ERROR: Net::SSH::ConnectionTimeout: Net::SSH::ConnectionTimeout

不确定可能导致knife solo失败的原因。我也试过指定-P流浪汉密码而不是身份文件，效果相同。
如何将knife solo连接到本地主机？
谢谢你的帮助！
