推荐答案

默认情况下，AWS Elastic Compute Cloud(EC2)端口受名为安全组的应用程序层防火墙保护(在启动实例之前指定了此设置).

By default AWS Elastic Compute Cloud (EC2) ports are protected by Application Layer firewall called Security Group (you specified this setting prior launching the Instance).

默认情况下，在安全组中没有打开像ping响应icmp端口那样的默认入口端口.话虽如此，您想检查您的EC2实例安全组并查找InBound Rule"ICMP"端口，以确保该端口正在接受来自启动ping的公用IP地址的流量.

In the Security Group by default there are no default ingress ports open like icmp ports that respond to ping. Having said that you would like to check your EC2 Instance security group and look for InBound Rule "ICMP" port make sure that it's accepting traffic from your public IP address that initiate the ping.
