Becoming Superuser (root)

Most administrative tasks such as adding users require that you log in as root (UID=0) first. The root account is also known as the superuser account because it's used to make system changes and can override user file protection in emergency situations.

The superuser account should only be used to perform administrative tasks to prevent indiscriminate changes to the system.

You can either log into the system as superuser or use the su(1M) command to change to the superuser account.

How to Become Superuser (root)

Become superuser by one of the following methods. Both methods require that you know the root password.

• Change to the superuser account by using the su command.

  % su Password: root_password #

  The pound sign (#) is the Bourne shell prompt for the superuser account.

• Log in as superuser on the system console.

  hostname console: root Password: root_password #

  This method is not enabled by default. You must modify the /etc/default/login file to log in as superuser on the system console. See "Securing Systems (Tasks)" in System Administration Guide, Volume II for information on modifying this file.

Setting Up User Accounts Task Map

User Information Data Sheet

You may find it useful to create a form like the one below to gather information about users before adding their accounts.

How to Customize User Initialization Files

1. Become superuser on the system where the users' home directories are created and shared.

2. Create a skeleton directory for each type of user.

   # mkdir /shared-directory/skel/user-type

   shared-directory	The name of a directory that is available to other systems on the network.
   user-type	The name of a directory to store initialization files for a type of user.

3. Copy the default user initialization files into the directories you created for different types of users.

   # cp /etc/skel/local.cshrc /shared-directory/skel/user-type/.cshrc # cp /etc/skel/local.login /shared-directory/skel/user-type/.login # cp /etc/skel/local.profile /shared-directory/skel/user-type /.profile

   ---

   Note -

   You can use the ls -a command to list . (dot) files.

   ---

4. Edit the user initialization files for each user type and customize them based on your site's needs.

   See "Customizing a User's Work Environment" for a detailed description on the ways to customize the user initialization files.

5. Set the permissions for the user initialization files.

   # chmod 744 /shared-directory/skel/user-type/.*

Example--Customizing User Initialization Files

The following example customizes the C-shell user initialization file in the /export/skel/enduser directory designated for a particular type of user.

# mkdir /export/skel/enduser
# cp /etc/skel/local.cshrc /export/skel/enduser/.cshrc
 
(Edit .cshrc file-see "Example--.cshrc File ")
# chmod 744 /export/skel/enduser/.*

How to Start Admintool

1. Verify that the following prerequisites are met. To use Admintool, you must:

   • Have a bit-mapped display monitor. The Admintool software can be used only on a system with a console that is a bit-mapped screen such as a standard display monitor that comes with a Sun workstation.

   • Be running an X Window System, such as the OpenWindows environment.

   • Be a member of the sysadmin group (group 14).

   If you want to perform administration tasks on a system with an ASCII terminal as the console, use Solaris commands instead. See useradd(1M) for more information.

2. Start Admintool.

   $ admintool &

   The Users main window is displayed.

Example--Starting Admintool

This is the Users main window, which enables you to manage user account information.

How to Add a Group

1. Start Admintool, if it's not already running.

   See "How to Start Admintool" for more information on starting Admintool.

2. Choose Groups from the Browse menu.

   The Groups window is displayed.

3. Select Add from the Edit menu.

   The Add window is displayed. If you need information to complete a field, click on the Help button to see field definitions for this window.

4. Type the name of the new group in the Group Name text box.

5. Type the group ID for the new group in the Group ID text box.

   The group ID should be unique.

6. (Optional) Type user names in the Members List text box.

   The list of users will be added to the group. User names must be separated by commas.

7. Click on OK.

   The list of groups displayed in the Groups window is updated to include the new group.

Example--Adding a Group

The following example adds a group named users that has a group ID of 101.

How to Add a New User Account

1. (Optional) Fill out the user information data sheet on "User Information Data Sheet".

2. Start Admintool, if it's not already running.

   See "How to Start Admintool" for more information.

3. Choose Add from the Edit menu.

   The Add User window is displayed.

4. Fill in the Add User window.

   If you need information to complete a field, click on the Help button to see field definitions for this window.

5. Click on OK.

   The list of user accounts displayed in the Users main window is updated to include the new user account.

Where to Go From Here

If you created a user's home directory, you must share the directory so the user's system can remotely mount it. See "How to Share a User's Home Directory" for detailed instructions.

If disk space is limited, you can set up a disk quota for the user in the file system containing the user's home directory. See "Managing Quotas (Tasks)" in System Administration Guide, Volume II for information on setting disk quotas.

Example--Adding a New User Account

The following example adds the user kryten to the system.

How to Share a User's Home Directory

1. Become superuser on the system that contains the home directory.

2. Verify that the mountd daemon is running.

   # ps -ef | grep mountd root 176 1 0 May 02 ? 0:19 /usr/lib/nfs/mountd

   The /usr/lib/nfs/mountd line is displayed if the mountd daemon is running.

3. If the mountd daemon is not running, start it.

   # /etc/init.d/nfs.server start

4. List the file systems that are shared on the system.

   # share

5. Determine your next step based on whether the file system containing the user's home directory is already shared.

   If the File System Containing the User's Home Directory Is ...	Then ...
   Already shared	Go to the verification step below.
   Not shared	Go to Step 6

6. Edit the /etc/dfs/dfstab file and add the following line.

   share -F nfs /file-system

   file-system

   Is the file system containing the user's home directory that you need to share. By convention, the file system is /export/home.

7. Share the file systems listed in the /etc/dfs/dfstab file.

   # shareall -F nfs

   This command executes all the share commands in the /etc/dfs/dfstab file, so you do not have to wait to reboot the system.

8. Verify that a user's home directory is shared, as follows:

   # share

Where to Go From Here

If the user's home directory is not located on the user's system, you have to mount the user's home directory from the system where it is located. See "How to Mount a User's Home Directory" for detailed instructions.

Example--Sharing a User's Home Directory

# ps -ef | grep mountd
# /etc/init.d/nfs.server start
# share
# vi /etc/dfs/dfstab
 
(The line share -F nfs /export/home is added.)
 
# shareall -F nfs
# share
-               /usr/dist                ro   "" 
-               /export/home/user-name     rw   ""  

How to Mount a User's Home Directory

1. Make sure that the user's home directory is shared. See "How to Share a User's Home Directory" for more information.

2. Log in as superuser on the user's system.

3. Edit the /etc/vfstab file and create an entry for the user's home directory.

   system-name:/export/home/user-name - /export/home/user-name nfs - yes rw

   system-name	Is the name of the system where the home directory is located.
   /export/home/user-name	Is the name of the user's home directory that will be shared. By convention, /export/home contains user's home directories; however, this could be a different file system.
   -	Are required placeholders in the entry.
   /export/home/user-name	Is the name of the directory where the user's home directory will be mounted.

   See Chapter 28, Mounting and Unmounting File Systems (Tasks) for more information about adding an entry to the /etc/vfstab file.

4. Create the mount point for the user's home directory.

   # mkdir -p /export/home/user-name

5. Mount the user's home directory.

   # mountall

   All entries in the current vfstab file (whose mount at boot fields are set to yes) are mounted.

6. Use the mount command to verify that the home directory is mounted.

Example--Mounting a User's Home Directory

# vi /etc/vfstab
 
(The line  venus:/export/home/ripley - /export/home/ripley
nfs - yes rw is added.)
 
# mkdir -p /export/home/ripley
# mountall
# mount

Solaris User Registration

Solaris User Registration is a tool for getting information about new Solaris releases, upgrade offers, and promotions. This graphical user interface (GUI) automatically starts when you first log into your desktop. The GUI lets you register now, later, or never. The registration process also provides Sun with the user's Solaris version, survey type, platform, hardware, and locale.

Accessing Solaris^SM Solve^SM

Completing the Solaris User Registration process provides access to Solaris Solve, an exclusive web site that offers valuable Solaris product information and solutions--all in one convenient location. It provides a quick and easy method for getting the most recent information on what's happening around the latest Solaris release. Solaris Solve also provides a preview to additional Sun contract and service opportunities.

Basically, the steps for completing Solaris User Registration and accessing Solaris Solve are:

1. Fill in the electronic Solaris User Registration profile.

2. Submit the profile by email or print the profile to fax or mail.

3. Create your login ID and password to access the Solaris Solve site.

   Even if you do not access the Solaris Solve site immediately, we recommend that you create your Solaris Solve login ID and password during the Solaris User Registration process. A Solaris Solve login ID and password should contain 6 to 8 alphanumeric characters without spaces and colons.

4. Access the Solaris Solve site.

Solaris User Registration is not invoked if the system administrator or user is logged in as superuser.

If you choose to register, a copy of the completed form is stored in $HOME/.solregis/uprops. If you choose to never register and change your mind later, you can start User Registeration by:

• Typing /usr/dt/bin/solregis at any command line prompt, or

• Clicking the Registration icon in the Application Manager's desktop tools folder (Common Desktop Environment desktop only)

See solregis(1) for more information.

Troubleshooting Solaris User Registration Problems

This section provides troubleshooting tips for solving Solaris User Registration problems.

The following table describes problems that may occur when you try to register, and actions required to resolve these conflicts.

How to Restart Solaris User Registration

Use the following procedure to restart the Solaris User Registration process.

1. Change to the $HOME/.solregis directory.

   % cd $HOME/.solregis

2. Remove the uprops file.

   % rm uprops

3. Restart the registration process.

   % /usr/dt/bin/solregis &

How To Disable User Registration

Table 2-4 shows how to disable User Registration before and after installing Solaris software. Before disabling Solaris User Registration, Sun recommends that system administrators register for their organization.
