我正在使用Net:Appliance::Session登录远程Unix服务器,但无法连接。以下是我的代码和调试输出:
my $s = Net::Appliance::Session->new({
personality => 'Bash',
transport => 'SSH',
host => $host,
});
$s->set_global_log_at('debug');
try {
print "Trying to connect\n";
$s->connect({ username => $user, password => $pass });
print "Executing command\n";
print $s->cmd($cmd);
}
catch {
warn "failed to execute command: $_";
}
finally {
$s->close;
};
输出结果为:

当我通过Putty登录时,会得到以下响应并成功登录:

我无法弄清楚我做错了什么。感谢您的任何帮助。
编辑:我认为我应该提到我在使用Cygwin。我已经手动登录到远程服务器,并且我的.ssh/known_hosts文件中的密钥也已经设置好了,但是在Cygwin中运行此程序时仍然会出现RSA错误。我在SO上看到了这个问题:“警告:已永久添加到已知主机列表”来自Git的消息并将
UserKnownHostsFile ~/.ssh/known_hosts
添加到我的配置文件中,但错误仍然存在。编辑2:当我在上面的程序中使用-vvv选项时,我得到以下输出:
