Starting and Ending a CLI Session
Open a telnet connection from a workstation on your network.
You initiate a telnet connection by issuing the following com-
mand from an IP host that supports telnet, for example, a per-
sonal computer running a telnet application such as NCSA
Telnet.
telnet <ip_address>
You must know the IP address of the Cayman Gateway before
you can make a telnet connection to it. By default, your Cayman
Gateway uses 192.168.1.254 as the IP address for its LAN
interface. You can use a Web browser to configure the Cayman
Gateway IP address.
Logging In
The command line interface log-in process emulates the log-in
process for a UNIX host. To logon, enter the username (either
admin or user), and your password.
• Entering the administrator password lets you display and
update all Cayman Gateway settings.
• Entering a user password lets you display (but not update)
Cayman Gateway settings.
When you have logged in successfully, the command line inter-
face lists the username and the security level associated with
the password you entered in the diagnostic log.
Ending a CLI Session
You end a command line interface session by typing quit from
the SHELL node of the command line interface hierarchy.
