安装 Net/SSH/Perl.pm

Question

我对使用 Perl 编写脚本相当陌生。我正在尝试 ssh 进入服务器并执行一些命令。我必须提供用户名和密码。

当尝试运行我到目前为止的脚本时（下面列出的代码）。我收到以下错误。

我假设这意味着我需要安装/制作 Net/SSH/Perl.pm，但是，当我按照我在网上找到的说明和教程进行操作时，没有一个起作用。

有人可以帮助我吗？我尝试过 CPAN 和 ppm，CPAN 表示找不到 net::ssh::perl 或其他变体该字符串的。而且 ppm 甚至不会运行，我在我的 perl 目录中没有看到它。非常感谢任何帮助！

// The code
#!/usr/bin/perl
use Net::SSH::Perl;

$uName = "username";
$pWord = "password";

$unitIp = $ARGV[0];

my $ssh = Net::SSH::Perl->new($unitIp, 35903);
$ssh->login($uName, $pWord);
my $out = $ssh->cmd("java -version");
print $out;

Answer 1

您可以尝试以下操作：

curl -L http://cpanmin.us | perl - --sudo App::cpanminus
cpanm Net::SSH::Perl

区分大小写。

解释：
第一行将安装“cpanm” - 恕我直言，安装模块最简单的方法是什么
第二行将安装模块 Net::SSH::Perl

Answer 2

而不是 Net::SSH::Perl 尝试使用 Net::SSH2 或者如果您位于 Unix/Linux 环境中Net::OpenSSH。它们安装起来要容易得多！

Answer 3

为什么应该使用 Net::OpenSSH 而不是其他 perl ssh？这是我通过 cpanm 安装后发现的：

Net::OpenSSH Vs Net::SSH::.* 模块

   Why should you use Net::OpenSSH instead of any of the other Perl SSH
   clients available?

   Well, this is the perldoc writters (biased) opinion:

   Net::SSH::Perl is not well maintained nowadays (update: a new
   maintainer has stepped in so this situation could change!!!), requires
   a bunch of modules (some of them very difficult to install) to be
   acceptably efficient and has an API that is limited in some ways.

   Net::SSH2 is much better than Net::SSH::Perl, but not completely stable
   yet. It can be very difficult to install on some specific operative
   systems and its API is also limited, in the same way as Net::SSH::Perl.

   Using Net::SSH::Expect, in general, is a bad idea. Handling interaction
   with a shell via Expect in a generic way just can not be reliably done.

   Net::SSH is just a wrapper around any SSH binary commands available on
   the machine. It can be very slow as they establish a new SSH connection
   for every operation performed.

   In comparison, Net::OpenSSH is a pure perl module that doesn't have any
   mandatory dependencies (obviously, besides requiring OpenSSH binaries).

Answer 4

只需在终端上键入 cpan，然后键入：force install Net::SSH::Perl

Answer 5

perl -MCPAN -e 'install Net::SSH::Perl'
