Just wondering how I get the hostname, i.e. the result of running 'hostname' on the command prompt, of an AWS machine (RHEL) via the Java API.

I can call the following

com.amazonaws.services.ec2.model.Instance awsInstance = ...
awsInstance.getPublicIpAddress())
awsInstance.getPrivateIpAddress())
awsInstance.getPrivateDnsName())
awsInstance.getPublicDnsName())

But cannot find out how to get the hostname - theres no getHostname() method.

  • The default hostname is the internal ip seperated by - instead of . Don't understand your problem. Commented Dec 17, 2014 at 13:13
  • Did you checked InetAddress if you are running jvm there? Commented Dec 17, 2014 at 13:16

Was able to get the hostname indirectly via:
