Ping an EC2 instance from your Local Machine

How to Ping an EC2 instance from your Local Machine #

In order to ping an AWS EC2 instance from your local machine:

1. Open the AWS EC2 console and click on the checkbox next to your EC2 instance
2. Click on Security and open the security group in a new browser tab

3. In the Inbound rules tab of your security group, click on Edit inbound rules

4. Click on the Add rule button and add the following inbound rule:

• Type: Custom ICMP - IPv4
• Protocol: Echo Request
• Port: N/A
• Source: Anywhere-IPV4

The security group rule allows ping requests to the EC2 instance from any IP address in the world.

5. Click save rules

6. Back in the EC2 console, verify the checkbox next to your EC2 instance is checked
7. In the Details tab, copy the Public IPv4 DNS address of your instance

8. Use the ping command to ping your EC2 instance from your local machine

Copied!
ping YOUR_EC2_PUBLIC_DNS

In our case to allow inbound ping requests to the instance, we had to add a new inbound security group to allow ICMP traffic.
