Understand the Umbrella Roaming Computer Hostname Sync Feature

Introduction

This document describes Umbrella's roaming computer hostname sync feature.

Overview

This article discusses what to expect when looking at a roaming client hostname on the dashboard. For all new deployments, the name is the current hostname. For deployments prior to 2020, please read this to learn about your client naming. The default for all clients prior to 2020 was the hostname at the time of installation.

Identifying a roaming computer

In the past, when the hostname of the machine itself changed, the label for the roaming client in the Umbrella dashboard did not update.  This was a big issue for long-term management so we have taken some steps to make the sync happen. The rest of this article outlines how the process works.

This feature works for both standalone roaming client installs and the integrated module for AnyConnect, and works for all operating systems. 

New roaming client installations made after Feb 1 2020:

All new roaming client installs now have 3 properties, and when an RC is first installed these are all the same:

• Identity Name: the name of the identity as it is in the Umbrella dashboard; this can be changed by an admin.
• Hostname: the current hostname of the endpoint computer; this is supplied by the roaming client installed on the endpoint and updated regularly.
• Original Hostname: the hostname at the time the roaming client was first installed.

The roaming client's Hostname property, if changed at the endpoint, syncs so the Identity Name to be the same as the Hostname. The only exception to this is if the administrator changes the Identity Name manually; a custom Identity Name stays the same if the hostname changes.

Existing roaming client installations prior to Feb 1 2020:

For existing roaming client installations, there are three scenarios:

1. The Hostname and Identity Name are the same. No action takes place here.
2. The Hostname has changed since the original installation. The Identity Name is now automatically refreshed with the Hostname property to be the same.
3. The Identity Name has been manually changed (renamed) since the original installation. The Hostname property is updated for this RC, but the Identity Name does not change. 

If you have changed an identity name and need to re-sync it to the hostname, you can literally just change it back yourself, but we have added a button to make it easier-- just click on the rename icon (the pen icon) and you’ll see the 'Match Hostname' option in blue:

NOTE: The changes to the hostname do not take place immediately.  When the computer's true hostname is changed, it can anywhere between a few hours to up to 24 hours to refresh in the dashboard.  This is because the sync update is a background process that runs through our install base and does so slowly to ensure consistency.
