Well in a related note I'm curious if there is a way to query the hostname of a machine remotely.

For example, if a network is migrated, I'd love to have a script to query a box by hostname or IP and have the machine spit out the hostname on the box located on that IP for verification. Smilie

HOSTNAME(5)							     hostname							       HOSTNAME(5)

NAME
hostname - Local hostname configuration file SYNOPSIS
/etc/hostname DESCRIPTION
The /etc/hostname file configures the name of the local system that is set during boot using the sethostname(2) system call. It should contain a single newline-terminated hostname string. The hostname may be a free-form string up to 64 characters in length; however, it is recommended that it consists only of 7-bit ASCII lower-case characters and no spaces or dots, and limits itself to the format allowed for DNS domain name labels, even though this is not a strict requirement. Depending on the operating system, other configuration files might be checked for configuration of the hostname as well, however only as fallback. You may use hostnamectl(1) to change the value of this file from the command line. HISTORY
The simple configuration file format of /etc/hostname originates from Debian GNU/Linux. SEE ALSO
systemd(1), sethostname(2), hostname(1), hostname(7), machine-id(5), machine-info(5), hostnamectl(1), systemd-hostnamed.service(8) systemd 208 HOSTNAME(5)
