Administering host names

This topic provides information on how to view or edit the /etc/hosts file, which is used to resolve domain names to IP addresses when DNS is not used or is unavailable. This feature allows you to specify a machine name instead of an IP address in the Outgoing MTA field even if you do not have a domain name server.

To administer the /etc/hosts file:

1. Start at the Administration menu, and select Message Networking Administration > Remote Machine Administration > Administer Hosts.
   The system displays the Administer Hosts page.
2. To modify the file contents, type in the text box:
   • The IP address in the first column.
   • The domain name that corresponds to the IP address in the second column.
   • The corresponding node name in the third column (optional).
3. Click Save to save the changes to the /etc/hosts file.

4. Click Return to Main to return to the Administration menu.
