Docker，can'；在Ubuntu14.04上ssh到rhel/centos容器

我已经花了将近一个星期的时间在这上面了，但还是没法用。我的Ubuntu 14.04笔记本电脑上安装了Docker 1.0.1。当我启动rhel/fedora/centos容器并安装sshd时，我无法建立ssh连接。使用Ubuntu容器也可以这样做

以下是我的ssh尝试的调试输出：

也许可以比较一下你的尝试，看看它有什么不同。完全一样的交易：$ssh localhost-p8022返回“连接关闭127.0.0.1”。这几乎感觉像是防火墙问题，除了它与Ubuntu映像一起工作，ssh调试显示握手成功。另一项测试显示rhel 6.5（同一Centos容器）上的Docker工作正常。似乎只有我的Ubuntu Docker主机（一台笔记本电脑，一台台式机）存在连接问题，并且仅当连接到rhel/centos映像时。令人沮丧。伙计，这令人沮丧。使用
