Specifications
The new username/password combination should be remembered and the password should be
composed in a way which makes it difficult to guess. The next step is to return the CLI to the
default context which is the top level of object categories.

Setting the Date and Time
Many cOS Core functions, such as event logging and certificate handling, rely on an accurate
date and time. It is therefore important that this is set correctly using the time command. A
typical usage of this command might be:
Device:/> time -set 2008-06-24 14:43:00
Notice that the date is entered in yyyy-mm-dd format and the time is stated in 24 hour hh:mm:ss
format.
Ethernet Interfaces
The connection of external networks to the Clavister Security Gateway is via the various Ethernet
interfaces which are provided by the hardware platform. On first-time startup, cOS Core scans for
these interfaces and determines which are available and allocates their names. The first interface
detected in the scan becomes the initial default management interface and this can only be
changed after initial startup.
All cOS Core interfaces are logically equal for cOS Core and although their physical capabilities
may be different, any interface can perform any logical function. With the E5, any of the GESW
interfaces can act as the default management interface. The other interfaces can be used as
desired. For the sake of example, it is assumed here that the G1 interface will be used for
connection to a protected network and the G2 interface will be used for connection to the public
Internet.
Setting Up Internet Access
Next, we shall look at how to set up public Internet access with the CLI. The setup wizard
described previously, provides the following four options:
A. Static - manual configuration.
B. DHCP - automatic configuration.
C. PPPoE setup.
D. PPTP setup.
The individual manual steps to configure these connection alternatives with the CLI are
discussed next.
A. Static - manual configuration
We first must set or create a number of IPv4 address objects. It is assumed here that the interface
used for Internet connection is G2, the ISP gateway IPv4 address is 10.5.4.1, the IPv4 address for
the connecting interface will be 10.5.4.35 and the network to which they both belong is
10.5.4.0/24.
