1.i开始两个会话，从192.168.0.3到192.168.1.3，一个是SSH会话，另一个是ping会话。当我进入“故障和接管”步骤时，“ ping”会话运行顺利，但SSH会话中断了。
2。FW1中'conntrackd -i'的打印内容如下
docker: error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.37/containers/create: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.
See 'docker run --help'.
3。FW2中'conntrackd -e'的打印如下
tcp 6 ESTABLISHED src=192.168.4.3 dst=192.168.1.3 sport=47634 dport=22 src=192.168.1.3 dst=192.168.1.100 sport=22 dport=47634 [ASSURED] [active since 27s]
4。FW2中INVAILD软件包的日志如下，
tcp 6 ESTABLISHED src=192.168.4.3 dst=192.168.1.3 sport=47634 dport=22 [ASSURED] [active since 6s]
所有这些似乎都不错，但不适用于SSH会话
