Question

我对使用perl编写脚本是相当新的。我试图ssh到服务器并执行一些命令。我必须提供用户名和密码。

尝试运行目前为止的脚本时（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时，没有一个有效。

有人可以帮助我。我尝试了CPAN和ppm，CPAN表示无法找到net::ssh::perl或该字符串的其他变体。 ppm甚至不会运行，我在perl目录中看不到它。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;

// the error that is returned

Answer 1

你可以试试这个：

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

区分大小写。

说明：第一行将安装“cpanm” - 什么是恕我直言安装模块的最简单方法
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或者如果你在Unix / Linux环境中Net::OpenSSH。它们更容易安装！

Answer 3

为什么要使用 Net :: OpenSSH 而不是其他perl ssh？这是我通过cpanm安装后找到的：

Net :: OpenSSH与Net :: SSH ::。* modules

   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

只需在终端上输入cpan，然后输入：force install Net :: SSH :: Perl

Answer 5

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

安装Net / SSH / Perl.pm
