To enter an initial NPK and a seed for encryption:

If necessary, create a password for the Technician Interface secure shell

by entering:

kpassword

is an alphanumeric string of up to 16 characters.

At the Technician Interface prompt, enter the secure shell by issuing the

following command:

ksession

If you issue the ksession command before setting a password, you will be

prompted to do so. Use the

kpassword command in step 1.

The prompt changes to

SSHELL.

Begin generating the encryption seed by entering:

kseed

The secure shell prompts you for a random seed value.

Type a random set of keystrokes. The secure shell informs you when you

have typed the required number of keystrokes.

Enter the following command:

kset npk 0x

<NPK_value>

is the 16-digit hexadecimal NPK value that you assigned to the

router that you are configuring. For more information, see “

Generating

NPKs” on page 2-5.

The

kset npk command stores your NPK value in the router NVRAM and

calculates a hash of this value that it stores in the router MIB.

Save the configuration by entering:

save config

<config_file_name>

config_file_name

> is the name you want to assign to the configuration file.

You cannot exit the secure shell without saving the configuration. This is

necessary so that upon rebooting the router with the saved configuration file,

the hash of the NPK in the MIB corresponds with the NPK in NVRAM.

Exit the secure shell by entering:

kexit

1 2 ... 38 39 40 41 42 43 44 45 46 47 48 ... 99 100
