Customization

Introduction

The Toshiba Magnia SG20 is a multifunction server appliance, designed to provide ease

of use and a friendly setup and management environment. The appliance is based on

Red Hat Linux 7.3. Because the Magnia SG20 is an appliance, it contains the Red Hat

7.3 RPMs needed to provide its feature set, as well as a variety of tools that allow direct

access and modification of the system for more experienced users. It does not contain

the entire suite of Red Hat 7.3 RPMs.

The Magnia SG20 provides a number of features targeted for small workgroups, remote

offices and small business. These features are configurable through its administrative

Web interface, and include:

❖Second HDD option (customer installable)

❖Built-in 7-port local LAN switch

❖Built-in wireless access point option

❖Built-in modem for dial-in networking and dial-out to Internet

❖Ethernet port for broadband Internet connections

❖Parallel port for printer sharing

❖LCD panel to display status (configurable)

❖Soft power shutdown

❖Easy-to-use client setup CD

❖System reports

❖File sharing (SMB)

❖Local email

❖Internet email retrieval service

❖Internet gateway (sharing of a single Internet port, dialup or broadband)

❖Firewall

Customization Introduction 7

❖Internet caching and content filtering

❖Backup and restore to clients or Internet

❖Primary HDD snapshot to second HDD (optional)

❖HDD used for additional space (optional)

❖User accounts and security

❖Disk quotas

❖Software upgrade process over the Internet

❖Internal hardware health monitoring

❖Built-in Intranet (customizable)

❖Easy-to-use VPN for remote access

❖FTP, Telnet

❖Digital Central Web site with picture, music sharing, and camera monitoring

❖Home automation controller interface

When customizing a Magnia SG20 image to create a new preinstall image for your

customers, it is important to ensure that the preset factory configuration is not modified

without care. Doing so can result in a custom image shipped from the Toshiba factory to

your end users with modifications which may result in increased service calls and a

reduced initial customer satisfaction with the new system. This guide outlines some basic

areas of which you should be aware, and provides some techniques for customizing the

system while maintaining a favorable customer out-of-box experience.

The Magnia SG20 uses a custom Web-based interface and a set of middleware tools to

enable the end user to manage the system. The internal mechanisms of this middleware

use unique methods to manage system configurations, such as template-based

configuration files and triggers. Direct modification of configuration files is not

recommended. This guide contains information about the internal management

techniques and how you might take advantage of them during your application

integration process.

Customization Customization overview 8

Customization overview

Before beginning the process of customizing a Magnia SG20 image, you can capture the

clean, unmodified image on another hard disk. Doing so enables you to reinstall a

factory-fresh image if you need to restart the integration process. See Custom image

backup on page 13 for more information.

Generally, the process of installing a custom application involves three basic steps:

❖Identifying and installing added Linux-based software to support your integration

process, such as libraries, newer versions of standard Linux software, or custom

support software.

❖Moving your application files onto the Magnia SG20 and installing it if necessary.

❖Optionally, adding links or Web pages to the Magnia SG20 Web-based administration

or preinstalled intranet pages.

Accessing the Magnia SG20

For most customization, installation and modifications access the system directly using

Telnet, using a shell command prompt. You can accomplish almost any task from this

environment.

Access the Magnia SG20 by performing the following steps:

1Set up a client computer connected to a private Ethernet port. Verify you can access

the Web administration pages using the URL http://192.168.1.1. When this has been

verified, bring up a command prompt and run Telnet:

telnet 192.168.1.1

2When the Linux login prompt appears, use the account “telnetuser” with the default

password “toshiba”.

3When at a shell prompt, you can switch to the root account using the su command.

4When at a root command prompt, you can install, recompile or modify software for

your application integration.

Copying software to the Magnia SG20

When you have access to the Magnia SG20, you will need to copy your application to the

system, as well as possible additional Linux support software such as databases or other

tools. You can copy new software to the Magnia SG20 by using one of the following

protocols:

Customization Customization overview 9

❖FTP

❖SMB file sharing access (Samba)

To copy files using FTP, invoke a command prompt from any client attached to the

Magnia SG20 built-in Ethernet switch. When prompted, log in to the FTP as an

anonymous user (the default Magnia SG20 configuration only allows anonymous

access). Use normal FTP commands to copy files to the incoming directory. When these

files are transferred, use Telnet to browse to the /home/ftp/incoming directory. You

can then move and use these files as needed.

To copy files using file sharing, connect a client to the Magnia SG20 local network and

browse the network neighborhood. The Magnia SG20 will appear in the workgroup

“saworkgroup” and will have the (default) computer name of “myserver”. Navigate to the

share named “public”. Copy files to this directory, then use Telnet to move and use these

files within Linux as needed. The “public” share is mapped to the directory /home/

public on the Magnia SG20.

Modifying the Magnia SG20 GUI

When your application is installed and running on the Magnia SG20, you may wish to

provide additional links or methods of accessing your application Web interface. There

are several ways of accomplishing this:

❖Add descriptive text and a hyperlink to your own Web pages.

❖Add complete Web pages to the existing Web administration or preinstalled intranet.

❖Add your own intranet Web site.

Listing installed Linux packages

To determine the list of Linux packages installed on your copy of the Magnia SG20

preinstall image, use the RPM command. This will allow you to determine what revision

of each package has been installed on your working system. Use the following command

to list the installed RPMs:

rpm –qa

Customization User accounts and passwords 10

User accounts and passwords

Default accounts and passwords

The Magnia SG20 is delivered with three predefined accounts:

❖applianceadmin: This account is the primary administrative account for the Magnia

SG20. It has access to the entire Web Administration UI, as well as complete access

to all files on the system. It cannot be deleted using the Web Administration.

❖telnetuser: This account logs in to the system using Telnet. While not encouraged for

the typical end user, for developers it represents an important method of access to

the system.

❖root: This is the standard linux root administrative account with complete system

privileges.

All accounts are assigned a default password of “toshiba” when delivered from the

factory. Changing this password is not recommended, because doing so can make it

difficult or impossible for the end user to log in and administer the system.

Initial account creation

To assure that the default password for critical privileged accounts such as

applianceadmin are changed, the Magnia SG20 uses a specific mechanism to update

the password when the server is initialized. When the user creates the first user account,

the password to all three predefined accounts are changed to the password of this first

account.

An example scenario is for the user to open a new Magnia SG20, turn it on, and connect

a PC to the built-in network. The user then runs the Setup CD to configure the client PC.

During the Setup CD setup process, the Setup CD software creates a new level 3

account on the server (for example, “jsmith”). The user also selects a password at this

time (for example “maxmoney1”). This process changes the passwords for the

predefined accounts to “maxmoney1”.

NOTE: Do not change the default passwords of the system.

NOTE: Do not create a new user on your Magnia SG20 using the Setup CD or the

Administrative Web interface. Use the existing applianceadmin account to access

the Web Administration or to access Network Neighborhood. Use the existing Telnet

and root accounts to access the system using Telnet. Modifications to the system

internals can be accomplished using these accounts.
