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?
This issue is caused by not enabling enableDnsHostnames
in your VPC configuration.
enableDnsHostnames
Indicates whether the instances launched in the VPC get DNS hostnames. If this attribute is true, instances in the VPC get DNS hostnames; otherwise, they do not. If you want your instances to get DNS hostnames, you must also set the
enableDnsSupport
attribute to true.
