HP-UX/Tru64 UNIX System Administration Interoperability phần 10 pot

Commands and Utilities The User and Group Accounts portion of the HP-UX SAM utility and the Tru64 UNIX SysMan Account Management utility both offer a graphical user interface for adding

Group Accounts

Group accounts offer a means of sharing system resources among certain users and restricting them from others It is possible, even necessary, for some users to be assigned to more than one group This section describes the commands and utilities, and the tasks involved for adding, modifying, and removing group accounts on each operating system

The group account nobody differs between both operating systems Under HP-UX, this account cannot own any files; under Tru64 UNIX, the nobody user account can own files

Group Identifiers

It is important to note that there are discrepancies between the operating systems in the assignment of group identifiers (GIDs) to group accounts

Commands and Utilities

The User and Group Accounts portion of the HP-UX SAM utility and the Tru64 UNIX SysMan Account Management utility both offer a graphical user interface for adding, modifying, and deleting group accounts Also, both operating systems offer the groupadd, groupmod, and groupdel commands

SysMan Account Manager

The Tru64 UNIX SysMan interface also provides a utility that enables you to add, modify, and delete group accounts This is the preferred method under Tru64 UNIX The following illustrates the Manage Local Users window of the SysMan Account Manager utility This chapter provides step-by-step information on how to manage local group accounts using this utility

The groupadd command

This command creates a group on the system by adding the appropriate entry to the /etc/group file Both operating systems have the same options, but Tru64 UNIX also features the following options:

Tru64 UNIX -P creates a PC group only

-x extended_option allows you to enter any number of extended options

See the appropriate groupadd reference page for more information

Chapter 15

328

The groupmod command

This command modifies an existing group account on the system by changing the appropriate entry in the /etc/group file Both operating systems have the same options, but Tru64 UNIX also features the following options:

Tru64 UNIX -D displays and sets the default values used by the account management utilities

-P modifies a PC group, which was created with the groupadd command

-x extended_option allows you to enter any number of extended options

See the appropriate groupmod reference page for more information

The groupdel command

This command deletes a group account from the system There are no options in the HP-UX version of this command, but Tru64 UNIX also features the following options:

Tru64 UNIX -P removes a PC group only

-x extended_option allows you to enter any number of extended options

See the appropriate groudel reference page for more information

Creating a Group Account

The following sections describe how to add a group account using the HP-UX System Administration

Manager and the Tru64 UNIX Account Management under SysMan

Creating a Group Account using HP-UX SAM

Follow this procedure to create, or add, a group account:

1 Log in as root or use the su command to switch user to superuser

2 Invoke SAM

3 Select the Accounts for Users and Groups icon The Accounts for Users and Groups window opens

4 Select the Groups icon The Groups dialog box opens

5 Select Actions->Add The Add a New Group dialog box opens.

6 Enter the Group Name

7 The Group ID field displays the next available GID To change it, first verify that the GID you want to assign does not belong to any other group on the system, then enter the new GID

8 Optionally select users from the Users to Include in Group list

9 Select OK

The dialog box closes and a confirmation dialog box announces that the group is being added to the system The Groups dialog box is updated to list the new group account

Chapter 15

330

Creating a Group Account using Tru64 UNIX SysMan Account Management

Follow this procedure to create, or add, a local group account:

1 Log in as root or use the su command to switch user to superuser

2 Invoke the SysMan Account Management utility in any of the following ways:

• Enter the command sysman to open the SysMan Main Window, select Accounts, select Manage Local Groups

• Enter the command sysman accounts, select Manage Local Groups

• Enter command sysman groups

The Manage Local Groups dialog box opens

3 Select Add to display the Add a Group dialog box

4 Enter the group name in the Group name: field

5 Either enter the group identifier (GID) in the Group ID field or leave it blank, which causes Account Management to use the next available GID Ensure that the GID you enter does not already exist

6 Select a user from the list shown and select Apply to assign that user to the group Repeat this step for each group member

Group members are highlighted in the list Select the user again and select Apply to remove a user from the group.

7 Select OK

Modifying a Group Account

The following sections describe how to modify a group account using the HP-UX System Administration Manager and the Tru64 UNIX Account Management under SysMan Such modifications are assigning new group members and removing others

Modifying a Group Account using HP-UX SAM

Follow this procedure to modify a group account:

1 Log in as root or use the su command to switch user to superuser

2 Invoke SAM

3 Select the Accounts for Users and Groups icon The Accounts for Users and Groups window opens

Chapter 15

332

4 Select the Groups icon The Groups dialog box opens

5 Select the group from the list shown

6 Select Actions->Modify The Modify an Existing Group dialog box opens.

7 Optionally change the Group Name by entering the new name in the corresponding field

8 Optionally change the Group ID by entering its value in the corresponding field

CAUTION Exercise care when changing the Group ID Ensure that the new Group ID is not already

used by another group

Modifying a Group Account using Tru64 UNIX SysMan Account Management

Follow this procedure to modify the parameters of a local group account:

1 Log in as root or use the su command to change user to super-user

2 Invoke the SysMan Account Management utility in any of the following ways:

• Enter the command sysman to open the SysMan Main Window, select Accounts, select Manage Local Groups

• Enter the command sysman accounts, select Manage Local Groups

• Enter command sysman groups

The Manage Local Groups dialog box opens.

3 Select the group account from the list in this dialog box

4 Select Modify to display the Modify a Group dialog box This dialog box is nearly identical to the Add a Group dialog box

Current group members are highlighted

5 Optionally change the group name in the Group name: field

6 Optionally change the group identifier (GID) in the Group ID field or leave it blank, which causes Account Management to use the current GID Ensure that the GID you enter does not already exist if you decide
