Net::SSH::Win32Perl 挂起

Question

您好，我正在尝试在 windows xp 机器上的 unix 机器上做一个简单的 ls。它挂起并且不退出。可能是什么问题

 use Net::SSH::W32Perl;
 use diagnostics;

    my $host = 'host';
    my $ssh = new Net::SSH::W32Perl($host, debug => 1);
    $ssh->login('username', 'password');
    my $cmd = "ls";
    my($stdout, $stderr, $exit) = $ssh->cmd($cmd);
    print "$stdout";
    exit;

下面是输出，注意它已经能够使用密码验证登录，但它不能给出输出。这是为什么呢？

Answer 1

我最近遇到了同样的问题。 I found a solution in PerlMonks 这就是我如何让它为我工作的方法。

1. 确保您设置了 $ENV{HOME} 环境变量（如果未设置）。 Net::SSH 将在那里查找配置项。
2. 在 Net/SSH/Perl.pm 中，注释掉第 49 和 50 行并用my $proto_class = $ssh->protocol_class($proto); 替换它们
