Perl's Net::(SSH vs SSH2 vs OpenSSH)——我应该如何比较它们？

Question

希望通过 Perl 脚本在远程机器上执行 perl 脚本。似乎一种选择是使用 system()功能并创建一个 ssh key ，因此不需要密码。这导致我关注这个问题，另一个选项似乎是安装和运行这些 perl 模块之一:

Net::SSH

Net::SSH2

Net::OpenSSH

除了使用的协议(protocol)之外，我还应该与这些 Perl 模块进行比较吗？

Net::OpenSSH文档有 section描述各自的优缺点。以下是与您所询问的内容相关的一些摘录，但文档列出了更多内容:

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.

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.

Net::OpenSSH has a very perlish interface. Most operations are performed in a fashion very similar to that of the Perl builtins and common modules (i.e. IPC::Open2).

但是，平台的选择可能会限制您的选择。

On the other hand, Net::OpenSSH does not work on Windows, not even under Cygwin.

当然，该列表偏向于 Net::OpenSSH ，但它让您了解模块之间的主要区别。
