9.0 Managing Users:

Generally, users are created and managed within the MultiNet system through the

creation of the Business Unit. See section 6.2. Within a server environment a

user would be given specific access rights to areas on a server where they could

do things such as view, create, delete, modify and other actions to files while

limiting access to areas where they do not need to be. This protects the system

and other users.

User “root” and several other users were created on your MultiNet receiver at the

factory. Default passwords were assigned to those users. User root is typically

the most powerful user in a Linux server and has access to do anything on the

server. Other factory created users are AES Engineering and Technical Support

user access accounts that were created to provide factory assistance and support

for your system and the passwords are not published.

You should change the factory default password for user root to protect against

unauthorized access. See “Changing a user’s Password” below.

Remote access to a MultiNet receiver is possible once attached to a network. The

VNC Server program is configured to start automatically on boot up and this will

allow remote access. There are also other readily available programs that can

gain access without special programs running on the receiver. Not changing the

password could easily allow remote access to those that know or discover the

server exists on an available network.

Where users are mostly managed by the creation and deletion of the Business

unit, you will not typically need to create your own users directly. Changing

passwords of a user is one operation that must be done outside the Admin GUI.

See “Changing a user’s Password” below.

9.1 Adding a user:

This is done when you create a Business Unit. The username is the name you

give to the Business Unit during the Add Business Unit process.

9.2 Retrieving user Display Number and Password:

An initial password and a unique Display number are generated automatically

during the Add Business Unit process. The password and Display number for

users created in the Admin GUI are located in the file named “user_info”

located in root directory. Only the root user can read the file. This is the

directory you would be looking at after a successful login as user root. Type

the following command at a command prompt to view this file:

cat user_info<Enter>

After reviewing the information press Q to quit the viewer and return to the

command prompt:

If you are not in the root directory or to be sure you are type the following:

cd /root<Enter>

Or to view the from any other directory type the following command:

cat /root /user_info<Enter>

1 2 ... 53 54 55 56 57 58 59 60 61 62 63 ... 110 111
