Perl远程写文件连接报错Net::SFTP::Foreign

Question

当我手动运行这个 Perl 脚本时，它可以建立连接。但是当我实现到系统中时，它会显示:authenticity of the target host can't be established, the remote host public key is probably not present on the '~/.ssh/known_hosts' file .

我需要这方面的帮助和建议。

my $host = "xxxs.com";
my $sftp = Net::SFTP::Foreign->new($host,user => 'xxx', password => 'xxx',
                                   more => '-v',stderr_fh => $ssherr);

Answer 1

看看FAQ在 Net::SFTP::Foreign 文档中。它在 下归档主机 key 检查 并且是最后一个条目。这是一个摘录。

Host key checking

Q: Connecting to a remote server with password authentication fails with the following error:

The authenticity of the target host can not be established,
connect from the command line first

A: That probably means that the public key from the remote server is not stored in the ~/.ssh/known_hosts file. Run an SSH Connection from the command line as the same user as the script and answer yes when asked to confirm the key supplied.

那里也有一个例子。
