To Update the /etc/hosts file

The IP address and the name of the server must be added to the /etc/hosts on that server. Failure to add the IP address and name will cause Open Telecommunications Platform installation to fail.

1. Log in as root (su - root) to the server.

2. Verify that the /etc/hosts file has entries for loopback and the server primary and secondary Ethernet interfaces.

   1. Make certain that either of the following loopback entries is in the /etc/hosts file.

      127.0.0.1    localhost

      or

      127.0.0.1    localhost.localdomain    localhost

   2. Make certain that an entry exists for the server primary and secondary Ethernet IP address.

      For example:

      111.11.111.11 server_name_interface1.domain_name
      111.11.111.22 server_name_interface2.domain_name
      

      where:

      • 111.11.111.11 is the IP address of the primary Ethernet interface

      • server_name_interface1 is the primary name of the server being configured such as the external OTP installation server, the first OTP host, or the additional OTP host

      • 111.11.111.22 is the IP address of the secondary Ethernet interface

      • server_name_interface2 is the secondary name of the server being configured

      • domain_name is your corporate domain name

      The /etc/hosts should be similar to the following example.

      127.0.0.1    localhost.localdomain    localhost
      10.11.123.15 management-server.company.com
      10.11.123.16 management-server-port2.company.com
      

   3. Save and close the /etc/hosts file.

3. Reboot the server.
