+**Setup Hostname**
+
+Log into the hostname (ssh)
+
+Run the following command
+
+```
+sudo hostnamectl set-hostname NewHostName
+```
+
+Also need to update the hosts name
+
+```
+sudo vi /etc/hosts
+```
+
+***Example of old host file***
+
+```
+127.0.0.1       localhost
+127.0.1.1       old-hostname.vocus.co.nz old-hostname
+
+# The following lines are desirable for IPv6 capable hosts
+::1     localhost ip6-localhost ip6-loopback
+ff02::1 ip6-allnodes
+ff02::2 ip6-allrouters
+```
+
+***Example of updated host***
+
+```
+127.0.0.1       localhost
+127.0.1.1       New-hostname.vocus.co.nz New-hostname
+
+# The following lines are desirable for IPv6 capable hosts
+::1     localhost ip6-localhost ip6-loopback
+ff02::1 ip6-allnodes
+ff02::2 ip6-allrouters
+
+```
+
+While hostnamectl typically applies the changes immediately, some services or applications might still be referencing the old hostname. You can restart network services or reboot the system for a complete refresh, although often it's not strictly necessary.
+To restart network services:
+
+```
+sudo systemctl restart network-online.target
+```
+
+or just reboot
+
+```
+Sudo Reboot
+```
