perl - 使用Net::OpenSSH和Solaris SSH客户端的“Bad configuration option: ServerAliveInterval”

Question

我正在尝试使用 Net::OpenSSH 连接到远程主机:

my $ssh = Net::OpenSSH->new(
    $ip_address,
    user => $user,
    password => $password,
    timeout => 3600,
    master_opts => [ -o => "StrictHostKeyChecking=no" ],
    ctl_dir => $ENV{HOME}
);

但我收到以下错误:

command-line: line 0: Bad configuration option: ServerAliveInterval
Unable to connect to remote host: unable to establish master SSH connection: bad password or master process exited unexpectedly at t1.pl line 33.

我正在使用以下版本的SSH客户端:

$ ssh -V
SSH Version Sun_SSH_1.0.1, protocol versions 1.5/2.0.

我怎样才能解决这个问题？

Answer 1

Net::OpenSSH不支持Solaris SSH客户端。从docs:

The SSH client bundled with Solaris is an early fork of OpenSSH that does not provide the multiplexing functionality required by Net::OpenSSH. You will have to install the OpenSSH client.

Install the OpenSSH client，并确保它在您的路径中出现在系统 ssh之前。

或者，对 ssh_cmd使用 new 选项:

my $ssh = Net::OpenSSH->new($host, ssh_cmd => '/usr/local/bin/ssh');
