Location

You should consider the physical sites and network bandwidth when choosing the installation location of

the CentreWare Web server. These items include the number of devices to be managed, as well as the

anticipated scheduling impacts and network traffic during discovery, status renewal, email notifications,

and device management work processes.

NTFS

For security functionality, you must install CentreWare Web on systems running NTFS. If you do not have

NTFS, there is no security access checking.

Selecting an Account

During software installation, you are prompted to select an account for the application. You can change

the account using the CentreWare Web Configuration Utility application or using Windows Administrative

Tools.

Print Queue Management

The application can monitor print queues on Windows workstations in addition to printers. Printing

problems can occur on printer queues or on printers. The queue management capability allows you to

monitor and troubleshoot the problems in an end-to-end fashion (from queue to printer).

To get detailed information on a print queue, you must have local administrator privileges on the actual

server where the print queue is attached. You can configure CWW to use a domain user account, and if that

account has administrative privileges to the server where the queues reside, CWW can monitor and

troubleshoot issues with those queues.

Security Features

CentreWare Web uses the security features built into Microsoft Windows operating systems including:

User authentication and authorization

Services configuration and management

Secure Terminal Services support

Group policy deployment and management

Internet Connection Firewall including:

- Security Logging settings

- CMP settings

Print Queue Management

The application can monitor print queues on Windows workstations in addition to printers. Printing

problems can occur on printer queues or on printers. The queue management capability allows you to

monitor and troubleshoot the problems in an end-to-end fashion (from queue to printer).

Xerox® CentreWare Web Installation Guide

Installation

To get detailed information on a print queue, you must have local administrator privileges on the actual

server where the print queue is attached. You can configure CWW to use a domain user account, and if that

account has administrative privileges to the server where the queues reside, CWW can monitor and

troubleshoot issues with those queues.

Microsoft Active Directory

The recommended installation configuration for CentreWare Web in a Windows Server environment is to

install the application using the domain administrator’s account of the highest domain in the Microsoft

Active Directory (Active Directory) tree. This allows the application to have permissions to manage (add and

remove) queues throughout the directory tree or domain.

CentreWare Web works with Active Directory and NTFS security. For more information, visit the Microsoft

Web site at www.microsoft.com.

Proxy Server Settings

If you are using a proxy server to connect to the Internet, you must configure the proxy server or change

settings in your browser to prevent the proxy server from interfering with browser authentication to

CentreWare Web. You can configure the proxy server once you have installed the application. Proxy server

settings may be required when using the Auto Driver Download feature or when enabling SMart eSolutions

since communication is required outside the firewall.

1. Open CWW.

2. Go to Administration > E-mail & External Servers.

3. Select Use Proxy Server proxy.

4. Add and verify the server address.

5. Add and verify the proxy server port.

6. If proxy security is required, enter the username, domain, and password of the proxy server. Contact your

administrator for more information.

7. Click Test to verify the proxy server connection and authentication information that you entered. CWW

displays an Intenet Connect Test Passed messaged when th test is successful.

Installing

Otaining the Installer

1. Access the Xerox Web site at www.xerox.com/centrewareweb and locate the executable (.EXE) file for

CWW.

2. Download the file.

Running the Installer

When installing the application software, the user who is logged on must have administrator privileges. If

the SQL server resides on a different server, then both servers must be domain members and the logged-on

user must have administrator privileges on the remote SQL Server as well.

1. Run the .EXE file to extract the files and begin the installation. The installation program checks to see if

the Microsoft®.NET framework is installed. If it is not, then the installation stops. Install the required

Microsoft .NET framework as described in the Software Requirements section.

8. Restart the Xerox Scheduler Service and Xerox Discovery Service.

Modifying the CentreWare Web Account

The application runs as the user account that is configured during installation. The account is visible by

opening Windows Administrative Tools and viewing properties and identity. This account determines the

security permissions of the application. After installation, you can modify this account by using one of the

following methods:

CentreWare Web Configuration Utility. See the CentreWare Web Configuration Utility section for the pro-

cedure.

Windows Administrative Tools.

To modify the account using Windows Administrative Tools:

1. In Control Panel, click Administrative Tools > Component Services.

2. From the Component Services tree, click Component Services > Computers > My Computer > COM+Ap-

plications > Xerox CentreWare Web Components.

3. Right-click Xerox CentreWare Web Components and select Properties to access the application prop-

erties.

tab.

5. Close the application by right-clicking Xerox CentreWare Web Components and selecting Shut Down.

The components automatically start as the newly selected user the next time they are used.

Administrators and Power Users Groups

During installation, two Windows Security groups are created in the location where the application is

installed: CentreWare® Web Administrators, Power Users and SQL Users. Members of the Administrators

group have complete administrative and operational access to the application. They do not, however, have

administrative privileges on the application server. Power Users can change the contents of the application

database, but are not administrative in nature. Membership in this group is the minimum requirement for

access to the following functions:

Create and generate reports from the Reports page

Troubleshoot printers using the following tools:

- Troubleshoot Printer Action

- Troubleshoot Printers Wizard

- Remote Reboot Printer Action

Creation and administration of groups using the following functions:

- New Group page

- Copy to Group Printer action

Configure printers using the following tools:

Xerox® CentreWare Web Installation Guide

Installation

- Edit Properties

- Configuration Sets

The SQL Users group is used when it is not desirable for CWW to use the Network Services account. If the

SQL logon is changed, the user needs to be part of this group in order for CWW to operate properly.

The groups are standard Microsoft users groups and are managed as other groups on your system. Use

Windows Administration Tools to add or delete users in these groups:

Click Start > Control Panel > Administrative Tools > Computer Management > Local Users and Groups.

Anonymous Access

Anyone who has access to the network where CentreWare Web is installed can view portions of the

application. The areas that anonymous or unauthenticated users can access are limited to viewing groups,

printers, servers and queues, and troubleshooting. Administrative and device management functions

require an authenticated user, which is defined as:

An administrator of the server where CentreWare Web is installed, or

A member of the Administrators group where the application is installed, or

A member of the Power Users group where the application is installed. Members of this group have no

administrative privileges within the application, but can perform other functions that affect the data-

base. See Administrators and Power Users Groups section for a list.

Unauthenticated users are prompted for a valid username and password in areas of the application where

an action would modify the database, group, or Printer Properties, for example:

New group

Printer/queue install

Printer/queue deletion

Configure group

Configure server

Add/Delete server

Configure directory

Create/edit queue or printer E-Mail Alert Profiles

Install, Upgrade, Clone or Export wizard

Reports

Administration

Xerox® CentreWare Web Installation Guide

Getting Started

Upgrading the Application

For this release, you may upgrade from the two previous major releases. To upgrade from an earlier release

requires a new installation.

Basic Set Up Tasks

This section outlines the basic tasks necessary to input the data for configuring the application:

Discovering printers

Verifying discovery

Setting mail server parameters

Configuring historical data collection

Creating groups

Adding queue servers

Enabling Remote Services

Note: For more information, see the application online help or go to product support for Centreware Web

and select Documentation to view the CentreWare Web User Guide.

Discover Printers

Populate the CentreWare Web database initially with printers by running a discovery. If you did not run the

Getting Started Wizard to perform an initial discovery after installation, run the wizard. You can also use Dis-

covery Quick Configuration from the Administration > Quick Configuration page as an initial discovery.

Verify Discovery

After discovery concludes, use the Printers view page to verify that the printers you expected CentreWare®

Web to find are in the database. If you know of printers in an error state, such as Out of Paper, they should

be members of the Error group as well. Click the Error group (Printers view page) to verify.

Set E-mail Parameters

You must configure the e-mail setting on the Administration tab to send printer alerts and reports from Cen-

treWare Web.

To access e-mail server parameters, choose Administration > E-Mail & External Servers > Outgoing Mail

Server.

These parameters include:

Mail server name

CentreWare Web e-mail account name

Additional security information (if required)

Xerox® CentreWare Web Installation Guide

Getting Started

You can use the E-Mail & External Servers page of the application to add or change these parameters at

any time.

Note: Check Status Alerts on the Network Usage Configuration page if you plan to use this feature.

Configure Historical Data Collection

If you wish to track page counts and alerts for reporting purposes, you must enable and schedule the

collection of historical data. You can set collection to run as often as hourly, depending on need. To use

Historical Data, you must configure historical data collection for built-in groups on the Administration >

Network > Historical Data page. Custom Groups historical data collection can be enabled and configured

through a Group’s Configuration Group action.

Add Groups or Subgroups

You can sort network printers into different groups by using default groups, and by creating other custom

groups for your site. You can organize printers into groups according to the physical location, brand, or

other printer characteristic. You can also define subgroups to further sort printers.

Group membership can be either static or dynamic (automatic). Administrators assign printers to static

groups manually. Automatic assignment of printers to dynamic groups is done by creating membership

filters.

After verifying the success of your discovery, you can begin creating custom groups and assigning printers

to them. Your implementation plan should include information that describes the groups and subgroups to

create, as well as their assigned printers or filtering criteria.

Verifying Network Printer Discovery/Monitoring Requirements

For successful management by Centreware Web, all SNMP-based printer devices should support the mandatory MIB

elements and groups as defined by the following standards.

Network Printer

Discovery/Monitoring Requirements

Recommendations

RFC 1157 SNMP Version 1

RFC 1213 MIB-II for TCP/IP-based Internet

RFC 1514/2790 Host Resources MIB v1/v2

RFC 1759 Printer MIB v1

RFC 3805 Printer MIB v2

RFC 3806 Printer Finishing MIB

Optional: RFC 2271-2275 SNMP v3 Architecture

SNMP V3 Security Enhancements

SNMP is the most widely used in-band management protocol for communication among network

management stations and the devices being managed. In its current form, SNMP's security is limited to

three methods of access:

Read-Only

Write-Only

Read-Write

Xerox® CentreWare Web Installation Guide

Getting Started

Access from the management station (Centreware Web to the devices is granted by community strings,

which are the groups to which the devices belong). Although disabling the Write function can prevent most

in-band attacks, SNMP is a relatively insecure protocol, with nothing more than the community strings

acting as passwords.

SNMP V3 includes security and administration. The SNMP V3 framework supports multiple security models,

which can exist simultaneously in an SNMP entity. SNMP V3 messages contain a field in the header that

identifies which security model must process the message. To ensure some form of interoperability, a User-

based Security Model (USM) is implemented to defend against unauthorized modification of managed

elements and spoofing. Although SNMP V3 is a huge step forward in secure manageability, it cannot

prevent denial-of-service attacks. In addition, its security system must stand alone, meaning every device

must have a database of users/passwords. Since this is not likely to happen in most companies, all devices

are at risk.

Please note that the more robust security provided by SNMPV3 can slow run times; this is especially true for

printer groups with hundreds of devices. When managing large fleets of devices configured with SNMP v3,

you may notice longer wait times or timeouts when utilizing large group sizes.

There are many factors that can affect response time including network bandwidth, topography, meter

data sizes, device models, etc. For these reasons we recommend smaller groups when the communication

technology is SNMP v3 vs SNMPv1/v2.

Recommendations:

Xerox

Versalink

Devices – no more than 500 devices per group

Xerox

Altalink

Devices – no more than 600 devices per group

Xerox

ConnectKey

2.0 Devices – no more than 500 Devices per group

Use the above group sizes as a starting point to find a group size that works best for your environment. If

you adhere to these recommendations and still notice long communication times that result in timeouts,

continue to reduce the size of the groups until the issue is resolved.
