AWS error - sudo: unable to resolve host ip-10-0-xx-xx

I launched a new aws instance. My private ip is ip-10-0-xx-xx as per amazon console. Everytime when I do a sudo command, I get the following error 

sudo: unable to resolve host ip-10-0-xx-xx

How can I rectify this error?

Solution

  • You should enable the DNS hostnames on your VPC: http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/vpc-dns.html#vpc-dns-updating

    If for some reason, you cannot enable it, you can still use the /etc/hosts to make it resolve, but this is definitely not the recommended solution

    10.0.xx.xx ip-10-0-xx-xx
