The hostname parameter is used to identify the system at the CLI prompt. You must enter a
fully-qualified hostname for the system. The hostname parameter is also used in end-user notification
pages, end-user acknowledgement pages, and to form the machine NetBIOS name when the Web
Security appliance joins an Active Directory domain. It has no direct relationship with the hostname
configured for the interface.

Use the

sethostname

command to change the name of the Web Security appliance:

example.com> sethostname

example.com> hostname.com

example.com> commit
