Banyan UNIX Access Guide

Chapter 1 - Introduction to Banyan UNIX Access


Basic UNIX access procedures, including UNIX login and password configuration
The structure of UNIX on a Banyan server

Note: Although Banyan UNIX is based on UNIX System V.4, many changes have been made to the files and directories of UNIX System V.4 during the development of VINES. This book explains many of these differences.

Basics of UNIX Access

The System Maintenance menu of your server must have 12 options, as shown in Figure 1-1. If the menu has only 10 options, you must reinstall the software and choose either "You have access, Banyan does not" or "You and Banyan have UNIX access,"at the Password Installation menu. For more information on installing root access, see the VINES Server Installation Guide.

Figure 1-1. System Maintenance Menu Screen

You must have an established StreetTalk user name and password.
Your name must be on the AdminList of the server. This list is called AdminList@servername@servers, where servername is the name of your server. For example, if your server is named MONEY, your AdminList name is AdminList@money@servers.
You must know the System Maintenance password for your server.

Option 11 allows you to log in to UNIX.
Option 12 allows you to change the UNIX root password and set configuration parameters that affect root password access.

To Log in to UNIX

1. Select Option 11 (Access UNIX) from the System Maintenance menu. You are prompted for your StreetTalk name.

2. Enter your StreetTalk name. You are prompted for your StreetTalk password.

3. Enter your StreetTalk password.

Note: You can enter your password up to five times at this screen. If you do not enter the correct password on the fifth attempt, the software pauses for one minute, then returns to the System Maintenance menu.

You are prompted for the root password.

4. Enter the root password.

Configuring the UNIX Root Password

The current password
Password configuration rules, including the minimum length, the expiration period, and the number of entries in the password history list. (This restricts the re-use of passwords as explained in "Password History List," later in this chapter.

To Change the Current UNIX Access Password

1. Choose 1 (Change UNIX Access Password) at the Configure UNIX Access menu. This prompt appears:

Please enter the old password for root access:

2. Enter the old password. This prompt appears:

Please enter the new password for root access (E to exit):

If you enter E the Configure UNIX Access Menu appears.

3. Enter the new password. This prompt appears:

Please retype new password:

4. Enter the new password exactly as you typed it the first time.

Note: UNIX passwords are case-sensitive.

To Change the Password Configuration

1. Choose 2 (Change Password Configuration) at the Configure UNIX Access menu. This prompt appears:

Please enter root password:

2. Enter the current root password. This prompt appears:

Number of previous root passwords that cannot be re-used(1 - 20,none) [10]:

3. Enter the number of passwords that you want to keep on the password history list (see the next section for more information). This prompt appears:

Minimum Password Length (1-15, none) [none]:

4. Enter the smallest number of characters for a root password on your server. A long password is more secure, but may be more difficult to remember. This prompt appears:

Password expiration in weeks (1 - 52, never) [never]:

This prompt asks you to set an interval after which you will be forced to change the root password on this server.

5. Enter a number of weeks. The system asks you to confirm your choices, as shown below.

Number of passwords to remember: 10

Minimum Password Length: none

Password expiration in weeks: never

Is this information correct (y/n) [y]:

If you enter n, the software returns to step 1. If you enter Y, the Configure UNIX Access menu appears.

Password History List

Number of root passwords to remember:

Note: During the initial installation, the password you enter does not appear on the screen. The password is shown on the screen in Figure 1-3 to clarify the example.
