Question

我刚开始使用Net :: SSH :: Perl，似乎我遇到了一些奇怪的东西。如果我将交互式标志设置为1并输入我的密码，我将通过ssh远程登录到机器，但如果我关闭交互式标志或将其设置为0，则登录失败。我确认我能够使用Net :: SSH :: Perl登录我的本地机器，因此它必须是我为这个特定的远程机器做错的事情，其中底层操作系统是SuSE。我还确认我能够从终端窗口ssh到远程机器。

use Net::SSH::Perl;
my $cmd = 'uptime';
my $ssh = Net::SSH::Perl->new($host, interactive=> 0, debug => 1);
$ssh->login($user, $pass);
my($stdout, $stderr, $exit) = $ssh->cmd($cmd);
print $stdout;

以下是交互标志设置为0时从调试输出的日志。

我猜我做错了什么，所以如果有人能指出正确的方向那就太棒了。

感谢。

这部分：

localhost.localdomain: Authentication methods that can continue: publickey,keyboard-interactive.

表示服务器允许两种方法进行身份验证：

publickey - 公钥验证
- 你在评论中提到这不适合你。
keyboard-interactive - 您输入密码的位置
- 这只能在交互模式下工作，这一点不足为奇。

所以，你想要做的事情是不可能的。

好消息是，这听起来像X-Y Problem。如果您向我们提供有关真实问题的更多详细信息，我们可能会建议更好的方法。
