Question

我是Windows Perl的新手，我正在Net::SSH2上尝试使用Strawberry Perl。我有脚本的问题是无法连接到设备列表。我可以连接到列表中的第一个设备，但无法连接到第二个，第三个等等。我错过了什么。谢谢你的任何建议。

#!\usr\bin\Perl\bin\perl

use warnings;
use strict;
use NET::SSH2;
use MIME::Base64;

my $host = "C:/temp/devices.txt"; # input file
my $user = "XXX"; # your account
my $pass = "XXXXX"; # your password  64 bit mime
my $ssh2 = Net::SSH2->new();
my $result = "C:/temp/result.txt"; # output file

$ssh2->debug(1); # debug on/off

open(List, '<', "$host") or die "$!";
while(<List>) {
    chomp $_;
    unless ($ssh2->connect("$_")) {
        print "Unable to connect : $_\n";
        next;
    }

    my $dp=decode_base64("$pass");

    unless ($ssh2->auth_password("$user","$dp")) {
        print "Invalid Password\n";
        exit;
    }

    my $chan = $ssh2->channel();
    $chan->exec('sh ver');

    my $buflen =100000;
    my $buf = '0' x $buflen;
    my $read = $chan->read($buf, $buflen );

    warn 'More than ', $buflen, ' characters in listing' if $read >= $buflen;

    open (OUTPUT, '>>', $result) or die "$!";
    print OUTPUT "HOST: $_\n\n";
    print OUTPUT "$buf\n";
    print OUTPUT "\n\n\n";
    print OUTPUT

    $chan->close();
}

close (List);

Answer 1

您必须在循环内创建Net :: SSH2对象，因为无法使用一个Net :: SSH2对象连接到多个主机（或执行多个连接到同一主机）。

Answer 2

在 $ chan-＆gt; close（）;

之后致电 $ ssh-＆gt; disconnect（）

Answer 3

请勿在身份验证失败时退出（）;使用'next'移动到下一个List项目。

Answer 4

只需在while循环下放置 my $ ssh2 = Net :: SSH2-＆gt; new（）; 。

   warn 'More than ', BUFLEN, ' characters in listing' if $read >= BUFLEN;
   open (OUTPUT, ">", "C:/temp/$_.txt")or die "$!"; # new file for each devices
   print OUTPUT "HOST: $_\n\n";
   print OUTPUT "$buf\n";

   $chan->close();

   close HOST;

Perl Net :: SSH2模块无法在设备列表中工作
