The kseed command creates the seed that enables WEP to generate random

numbers. To create a TEK seed, you work in the secure shell of the router.

1. At the C shell prompt on a UNIX platform, or at the DOS prompt on a

PC, enter

ksession

You enter the secure shell, which prompts you for the password.

2. Enter the password.

Your password should be at least 10 to 12 characters long. It should not be

anything obvious. Change it often.

The prompt changes to SSHELL.

3. Enter the kseed command and press Return.

WEP asks

Do you wish to create the TEK Key File?

4. Press Return to create the TEK Key File.

WEP displays

To initialize the seed for the cryptographic random number generator,

please now enter a series of characters which you would consider to

be 'random.' As you enter them, dots '.' will be displayed to

indicate progress. If your string is not 'random' enough, questions

'?' will be displayed. In that case, modify the pattern you are

entering. When enough data is input, you will be prompted to stop

(near 3 lines of input)...

As you type, the screen displays a dot for each keystroke the WEP accepts:

... .... .... .... ....

.... .... .... .... ....

.... .... .... ..

If your keystrokes are not random enough, the screen displays ???

When you have entered a sufﬁcient number of random keystrokes, WEP

displays a message telling you you’re done, and returns you to the prompt.

All done, thank you!
