Chapter 5 - Command Line Preparation
The command line interface allows you to configure and monitor the IntraPort Carrier-8 VPN
Access Server in-band via Telnet or out-of-band with a terminal connected to the server’s
Console interface.

Note:
Proper syntax is vital to effective operation of command line management. Case is not
significant – you may enter commands in upper case, lower case, or a combination of the two.
Out-of-Band Command Line Management
You can use command line management and text-based configuration out-of-band as a perma-
nent management tool, or only temporarily in order to set the server’s IP parameters to allow
in-band Telnet access.
In order to access the command line out-of-band, do the following:
1.
Set a terminal or a PC equipped with VT100 terminal emulation to a baud rate of
9600, 8 bits, no parity, 1 stop bit and no Flow Control.
2.
Connect it to the server’s Console interface using the cable which was supplied with
the IntraPort Carrier-8.
3.
Press the <Return> key one or two times.
4.
Enter the default password letmein at the password prompt. The command line inter-
face prompt will appear on the screen.
If you plan to use out-of-band access for ongoing management of your server, you can find
further information on configuring your server in the documentation for the I/O card. Other-
wise, see the section later in this chapter on Setting Up Telnet Operation for information on
setting the server to allow Telnet access from hosts on its network.
Temporarily Reconfiguring a Host for Command Line Management
If no LAN-accessible interface (i.e., Ethernet) is installed in your IntraPort Carrier-8 VPN
Access Server, then you can only use the Console port for command line management. If an
Ethernet interface is installed, you can temporarily reconfigure an IP host in order to set the
server’s IP parameters to allow in-band Telnet access.
If you wish to set the server’s basic IP parameters in this fashion, the host must be on the same
Ethernet segment as one of the server’s Ethernet interfaces. You can then do the following:
1. Set the host’s IP address to 198.41.12.2, with a Class C subnet mask (255.255.255.0)
and then Telnet to 198.41.12.1.
2.
Enter the default password letmein at the password prompt. The command line inter-
face prompt will appear on the screen.
3.
Use the configure command and set the IPAddress, SubnetMask, and IPBroadcast
keywords in the IP Ethernet 0:0 section.
4.
Use the save command to save the changes to the device’s Flash ROM.
5.
Change the host’s configuration back to its original settings.
See the next section (
Setting Up Telnet Operation
) for information on setting the server to
allow Telnet access from hosts on its network.
