Cannot ping AWS EC2 instance
问题 I have an EC2 instance running in AWS. When I try to ping from my local box it is not available. How can I make the instance pingable? 回答1: Add a new EC2 security group inbound rule : Type: Custom ICMP rule Protocol: Echo Request Port: N/A Source: your choice (I would select Anywhere to be able to ping from any machine) 回答2: You have to edit the Security Group to which your EC2 instance belongs and allow access (or alternatively create a new one and add the instance to it). By default
