net::scp/net::scp::expect-如何处理密码与密钥身份验证

尝试其中一个,然后故障切换到另一个:

#! /usr/bin/perl

use warnings;
use strict;

use Net::SCP qw/ scp /;
use Net::SCP::Expect;

my @hosts = qw/ host1 host2 host3 /;
my $user  = "YOUR-USERNAME-HERE";
my $pass  = "PASSWORD-GOES-HERE";
my $file  = "file-to-copy";

foreach my $host (@hosts) {
  my $dest = "$host:$file"; 

  my $scp = Net::SCP->new($host, $user);
  unless ($scp->scp($file => $dest)) {
    my $scpe = Net::SCP::Expect->new;
    $scpe->login($user, $pass);

    local $@;
    eval { $scpe->scp($file => $dest) };
    next unless $@;

    warn "$0: scp $file $dest failed:\n" .
         "Public key auth:\n" .
         "    $scp->{errstr}\n" .
         "Password auth:\n" .
         "    $@\n";
  }
}
