+
+Modify hostname on |CL-ATTR|
+############################
+
+This guide describes how to modify and view the hostname of your 
+|CL-ATTR| system.
+
+
+By default, |CL| installations have a machine generated name. This 
+long string of letters and numbers is fine for computers, but is not 
+human-friendly. Administrators and users will often want to rename 
+their machines with a name that is easier to remember, type, and search 
+for. Renaming a machine also makes it easier to identify, by including 
+meaningful data in the name. A meaningful, human-friendly machine 
+name might:
+
+   * indicate the computer purpose e.g. “regression-test”
+   * indicate the owner e.g. “sally-test-box1”
+   * indicate the geographical location e.g. “az-bld2-lab”
+
+
+.. note::
+
+   There are three types of hostname: “static”, “transient”, and “pretty”. 
+   The most common is the static hostname. If the static hostname exists, 
+   it is used to generate the transient hostname, which is maintained by the 
+   kernel. Note that the transient hostname can be changed by DHCP or mDNS 
+   at runtime. The pretty hostname is a human readable name that is used 
+   for presentation to the user.
+
+   Static hostnames must be between 2 and 63 characters long, must start 
+   and end with a letter or number, and may contain letters (case-insensitive), 
+   numbers, dashes or dots.  Pretty hostnames can use free-form UTF8 characters,
+   to make the hostname more aesthetically pleasing for the user.  
+
+
+Setting your hostname
+*********************
+
+|CL| uses the :command:`hostnamectl` command to display and modify the 
+machine name. :command:`hostnamectl` is part of the **os-core** bundle. 
+
+This example sets the hostname to “telemetry-test-2-h15”, to identify a 
+|CL| telemetry test machine on the second floor at grid location H15. 
+Make sure to reboot after setting a new hostname.
+
+   .. code-block:: bash
+
+      sudo hostnamectl set-hostname telemetry-test-2-h15
+      sudo reboot
+
+
+View your hostname
+******************
+
+View your current hostname using the following command:
+
+   .. code-block:: bash
+
+      hostnamectl
+
+You should see output similar to:
+
+   .. code-block:: console
+
+      Static hostname: telemetry-test-2-h15
+      Pretty hostname: telemetry-test-2-h15
+      Icon name: computer-desktop
+      Chassis: desktop
+      Machine ID: 4d0d60207a904ebbab96680a51ac1339
+      Boot ID: 98d3514e5a984e8cbbdf46a2f0d6b397
+      Operating System: Clear Linux OS
+      Kernel: Linux 4.18.8-632.native
+      Architecture: x86-64
+
+ 
+**Congratulations!** You successfully modified the hostname of your |CL| system.
