Question

您好我正试图在Windows XP机器上的unix盒子上做一个简单的ls。它挂起并且也不会退出。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无法提供输出。那是为什么？

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。

如果未设置，请确保设置$ ENV {HOME}环境变量。 Net :: SSH将在那里查找配置项。
在Net / SSH / Perl.pm中，注释掉第49和50行并将其替换为my $proto_class = $ssh->protocol_class($proto);

Net :: SSH :: Win32Perl挂起
