Step D: Check the Hosts File - AWS Elemental Delta

This is version 2.3 of the AWS Elemental Delta documentation. This is the latest version. For prior versions, see the Previous Versions section of AWS Elemental Delta Documentation.

Step D: Check the Hosts File

If your network is not configured with DNS, you also need to add a static entry to the hosts file on your AWS Elemental Delta node. To do so:

To check the hosts file

  1. Open the file /etc/hosts in Nano as shown here: 

    sudo nano /etc/hosts

    You see something similar to this:

    132.0.0.1 SYS-1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 SYS-1 localhost localhost.localdomain localhost6 localhost6.localdomain6

  2. Add a line to the end of the file that has the IP address of the relay server, a space, and the hostname of the relay server as shown below. 

    192.0.2.0 ExampleMailHostname

  3. Use the keys Ctrl+o to save the file, then Ctrl+x to exit Nano.
