无法使用Ruby和net / ssh连接密钥
我无法使用’net-ssh’gem通过ssh从ruby连接，获得Net :: SSH :: AuthenticationFailed。 代码如下
require 'net/ssh' keys = ["path_to_private_key"] Net::SSH.start('host', 'user',:keys => keys, :verbose => :debug) do |ssh| #ssh code end 直接从命令行使用ssh：
ssh -i user@host
我的ssh API有错吗？ 我尝试了’user @ host’和’user’作为用户名，结果相同。
这是调试输出：

谢谢
$ ssh-keygen -t rsa $ ssh-copy-id -i ~/.ssh/id_dsa.pub user@machine $ ssh user@machine require 'net/ssh' require 'logger' Net::SSH.start( 'host', 'user', :host_key => "ssh-rsa", :encryption => "blowfish-cbc", :keys => [ "~/.ssh/id_rsa.pub" ], :compression => "zlib" ) do |session| ... end
那一定能帮到你！
