EC2 ubuntu-server: why are IPs not being pinged?

Question

Amazon Web Services

Amazon gives a free dedicated server for a year (ec2). Also gives out 2 IPs: private and simple. There is an SSH connection. The question is very noob: IPs from the Internet do not respond. How to make these IPs respond? Google didn't help me or just asked the wrong question...

Answer 1

Most likely, you need to fasten the elastic ip and allow pings in the security group
. Amazon does not give a dedicated server for a year, but allows you to use a certain amount of resources, in particular, enough hours to keep the micro instance running all the time, but I think they give 15GB of traffic there per month.
well, many will launch a powerful instance and then go nuts from a bill of several kilodollars.

Answer 2

Configure a firewall ("security group" which is for this ec2 instance). Check the firewall settings of the OS itself.

Answer 3

My card, which is required at registration, ends in July. That is, the card will be incapacitated and they will not be able to bill me in a year?
