Configure Hostnames

Updated: February 4, 2026

Overview

Use this task to configure domain names in the /etc/hosts file for enabling Zero Touch Deployment (ZTD) and Plug and Play (PNP) of FAR devices with Cisco IoT FND and TPS servers. This ensures hostname resolution and proper communication within the IoT network environment.

When onboarding Cisco IoT FND, configure domain names in the /etc/hosts file. Use this configuration for the Zero Touch Deployment (ZTD) and Plug and Play (PNP) of FAR devices. The domain name resolves the FND or TPS hostname to an IP address, facilitating communication with Cisco IoT FND.

Use the following instructions to configure hostnames in FND and TPS servers:

Procedure

1.

Edit hostname in the /etc/hosts file .

Example:

root@iot-fnd ~]# nano /etc/hosts

This displays the /etc/hosts file, allowing you to edit it by adding or updating hostnames with their corresponding IP addresses.
2.

Enter the domain name for the host IP address separated by a space or a tab.

Example:

209.165.200.225  fnd.iot.cisco.com
            209.165.201.1  tps.iot.cisco.com
3.

Save the changes by selecting Y and exit.

4.

Validate the updated hostname using the following command:

Example:

[root@iot-fnd-oracle ~]# ping fnd.iot.cisco.com
            64 bytes from fnd.iot.cisco.com (209.165.200.225): icmp_seq=1 ttl=64 time=0.052 ms
            64 bytes from fnd.iot.cisco.com (209.165.200.225): icmp_seq=2 ttl=64 time=0.058 ms
            64 bytes from fnd.iot.cisco.com (209.165.200.225): icmp_seq=3 ttl=64 time=0.048 ms

The updated hostname is displayed along with the corresponding IP address.
5.

To view the hostnames with the corresponding IP addresses, use the following command:

Example:

[root@iot-fnd ~]# cat /etc/hosts
            127.0.0.1  iot-fnd-oracle localhost localhost.localdomain localhost4 localhost4.localdomain4
            ::1        iot-fnd-oracle localhost localhost.localdomain localhost6 localhost6.localdomain6
            209.165.200.225  fnd.iot.cisco.com
            209.165.201.1  tps.iot.cisco.com

You've successfully configured hostnames on Cisco IoT FND and TPS servers.

What to do next

Configure NTP servers and IP host entries.
