Chapter 8 Configuring Basic Settings
Setting the Hostname
The password is saved in the configuration in encrypted form, so you cannot view the original password
after you enter it. Enter the enable password command without a password to set the password to the
default, which is blank.
Setting the Hostname
When you set a hostname for the security appliance, that name appears in the command line prompt. If
you establish sessions to multiple devices, the hostname helps you keep track of where you enter
commands. The default hostname depends on your platform.
For multiple context mode, the hostname that you set in the system execution space appears in the
command line prompt for all contexts. The hostname that you optionally set within a context does not
appear in the command line, but can be used by the banner command $(hostname) token.
To specify the hostname for the security appliance or for a context, enter the following command:
hostname(config)# hostname name
This name can be up to 63 characters. A hostname must start and end with a letter or digit, and have as
interior characters only letters, digits, or a hyphen.
This name appears in the command line prompt. For example:
hostname(config)# hostname farscape
farscape(config)#
Setting the Domain Name
The security appliance appends the domain name as a suffix to unqualified names. For example, if you
set the domain name to “example.com,” and specify a syslog server by the unqualified name of “jupiter,”
then the security appliance qualifies the name to “jupiter.example.com.”
The default domain name is default.domain.invalid.
For multiple context mode, you can set the domain name for each context, as well as within the system
execution space.
To specify the domain name for the security appliance, enter the following command:
hostname(config)# domain-name name
For example, to set the domain as example.com, enter the following command:
hostname(config)# domain-name example.com
Setting the Date and Time
This section describes how to set the date and time, either manually or dynamically using an NTP server.
Time derived from an NTP server overrides any time set manually. This section also describes how to
set the time zone and daylight saving time date range.
Note In multiple context mode, set the time in the system configuration only.
