perl - Net::OpenSSH::Gateway->find_gateway 在设置 ControlPersist 选项时失败

Question

我正在尝试使用 Net::OpenSSH::Gateway 创建持久网关连接。下面是我使用的代码片段。

my %proxy_opts = (
 host => $host,
 port=>$port,
 password=>$password,
 user=>$user ,
 scheme=>"ssh",
 ssh_cmd => '/usr/bin/ssh',
 master_opts =>
               [ -o=>"StrictHostKeyChecking=no",
                 -o=>"TCPKeepAlive=no",
                 -o=>"ServerAliveInterval=30",
                 -o=>"ServerAliveCountMax=90",
                 -o=>"ControlPath=/tmp/ssh-master-%h_%p_%r",
                 -o=>"ControlPersist=yes"
                ]
);

my %gateway_settings = ( proxies=>[ {%proxy_opts} ]);
my $gateway = Net::OpenSSH::Gateway->find_gateway(%gateway_settings, errors=>$errors);

我收到以下错误。但是，如果我删除选项 ControlPath 和 ControlPersist ，整个事情就可以正常工作。

[ERROR ] unable to establish master SSH connection: bad ssh master at /root/.libnet-openssh-perl/spangeni-j1.zscaler.-31930-744378, socket owned by pid 31933 (pid 31931 expected)

Answer 1

我认为这是模块中的错误。模块Net::OpenSSH::Gateway CPAN 上不存在，作者已经说过:

I have not published it on CPAN yet because, even it is already functional, I have found some problems with its internal architecture that I want to solve first. -Source

此外，如果您看到 Net::OpenSSH 的文档您会看到网关是一项实验性功能。



顺便说一句 OpenSSH 是什么版本你正在用吗？ ControlPersist 需要 OpenSSH 5.6 或更新。
