Info: How does Server Agent determine hostname displayed in registered clients?

Info:

This article describes how Server Agent determines the hostname that is then displayed in Registered Clients list in Aperture.

More Info:

The Server Agent will report back to Venafi Trust Protection Platform (TPP) the hostname of the system. This hostname value is determined by a system call made by the Agent.

The call is gethostname (https://man7.org/linux/man-pages/man2/gethostname.2.html). This function is used by hostname command at least in Linux (https://man7.org/linux/man-pages/man1/hostname.1.html). 

This means that on a Linux system we can simply run this command from terminal session to see what the Agent should be reporting as the hostname:

hostname

On Windows you can use the following PowerShell command:

[System.Net.Dns]::GetHostByName($env:computerName)
