我的 perl 模块有问题，我正在尝试使用 CPAN 中的 OpenSSH 模块连接到远程服务器，并且我已经正确给出了用户名和密码，但是当我从浏览器运行我的 CGI 时，我看到以下错误消息“
can't ssh:unable to establish master SSH connection: bad password or master process exited unexpectedly
需要立即回复并等待， 提前致谢。
这是我的代码
#!/usr/bin/perl -w
use CGI;
use Data::Dumper;
use strict;
use CGI::Carp qw(fatalsToBrowser);
use Net::OpenSSH;
my $query = CGI->new();
#my $mach_name=$query->param('mach_name');
my $mach_name= '****.cce.***.com';
my $user='root';
my $passwd='*******';
my $ssh = Net::OpenSSH->new("$mach_name",user => "$user" , passwd => "$passwd
", master_opts => [-o => "strictHostKeyChecking=no"]);
$ssh->error and die "can't ssh:" . $ssh->error;
my $mem_info =$ssh->capture("ioscan -m lun");
print "$mem_info";
print "Content-type: text/html\n\n";
print "<html><head><title>test page</title></head>\n";
print "<body><p>Dicovering Machine Please wait....</p>\n";
print "<p>$mach_name</p>";
print "<p><b>Swap Memory :$mem_info </b> </p>";
print "</body></html>";
如果我通过命令行运行相同的程序，它会获取o/p，但通过浏览器我会看到上述错误，我已经正确给出了密码和用户名
最佳答案
当我将超时从 10 秒增加到 15 秒时，我的问题得到了解决，因为设备使用的是较旧的 SSH 守护程序版本，但我的进行客户端连接的 Linux 服务器已升级，当然它首先探测较新的密码。
my $ssh = Net::OpenSSH->new(
$host,
port => $port,
user => $user,
password => $pass,
timeout => 15, # <= this was 10 and now is 15
kill_ssh_on_timeout => 1,
strict_mode => 0,
master_opts => [-o => "StrictHostKeyChecking=no", '-vvv'], #<= -vvv helped much
ctl_dir =>'/tmp/libnet-openssh-perl',
