Introduction

Chapter 1

This chapter guides you through the process of connecting and conﬁguring the Cobalt Qube 2 for your network and user community. A typical setup process takes less than 15 minutes, after which you can begin using all of the Qube 2 services.

If the Qube 2 has been conﬁgured previously for a different network, refer to “Changing network conﬁguration” on page 156 in Appendix A.

Qube 2 setup

The setup process occurs in two phases.

• “Phase 1: Making the Connection” explains the physical connection of the Qube 2 to a power source and the network.

• “Phase 2: Setting up with the Web browser” explains the network integration process and allows the administrator to select services and create users and groups, using any browser-enabled computer.

Chapter 2

Setting up the Qube 2

Phase 1: Making the Connection

Connecting to the network

Connect the Primary Network Interface (10/100 BaseTX) of the Qube 2 to your local network with a twisted-pair ethernet cable; see Figure 5.

Chapter 2

If you want to connect the Qube 2 to the Internet, you can use either an external modem or the Secondary Network Interface (if you have a leased line to the Internet).

• For a modem connection to the Internet: Connect a standard (Hayes-compatible) external modem to the serial port of the Qube 2; see Figure 5.

• For a leased line connection to the Internet: Connect the Secondary Network Interface (10/100 BaseTX) to your Internet line with twisted-pair ethernet cabling; see Figure 5.

Connecting the locking power supply

To connect the locking power supply, pull back on the sliding connector and push the connector into the 12V DC locking power socket; see Figure 5. Connect the other end of the power supply cord to an electrical outlet.

Powering on the Qube 2

Turn on the power by pressing the On/Off switch on the back of the Qube 2; see Figure 2.

The hard disk spins up and the fan turns on. The light bar on the front of the unit blinks a few times and then glows steadily.

A number of status messages are displayed on the LCD screen as the Qube 2 completes its boot process.

Caution: It is important to follow the proper power-down procedure before turning off the Qube 2. Refer to “Powering down” on page 158 in Appendix A.

Conﬁguring Network Settings

Now that you have made the network and power connections, you can conﬁgure the network settings.

The Qube 2 requires speciﬁc network information in order to function properly. Depending on the network environment, the Qube 2 may be able to obtain all of the necessary information from a dynamic-host-conﬁguration-protocol (DHCP) server on the network. If

Setting up the Qube 2

so, the Qube 2 tries to conﬁgure itself automatically. If not, you must enter the necessary information manually, using the LCD console on the back of the Qube 2; see Figure 6.

Before you proceed, make sure you have the following information:

• the IP address assigned to the Qube 2

• the subnet mask of your network

Note: A gateway or router address is not required for a Qube 2 that is only connected to a local area network (LAN). If you connect to another network through the Qube 2, you require a gateway address. If you use a modem to connect to the Internet, the modem serves as the gateway.

Using the LCD console to conﬁgure the network

Figure 6 shows the LCD console for the Qube 2.

The LCD screen on the back of the Qube 2 displays two lines of text. The top line of the LCD presents instructions on data to enter; the bottom line displays the data already entered. Use the arrow buttons below the LCD screen to enter the required network information manually.

Appendix A, “Using the LCD console”, on page 155 provides more information about the LCD console.

Chapter 2

During startup, the LCD screen on the back of the Qube 2 displays status information about the boot process itself. When setting up the Qube 2, you use the LCD console to enter network conﬁguration information for the Qube 2. Once the Qube 2 is running, the LCD console is used to change network conﬁguration information, reboot the unit and power down the unit.

The arrow buttons function as follows:

The Left arrow button moves the cursor to the left between the digits displayed in the LCD screen.

The Right arrow button moves the cursor to the right between the digits displayed in the LCD screen.

The Up arrow button increases the digit located at the cursor position.

The Down arrow button decreases the digit located at the cursor position.

Conﬁguring the Qube 2 through a DHCP server

The Qube 2 ﬁrst checks to see whether a DHCP server is present on the network. If there is a functioning DHCP server that is set up to serve leased IP addresses, the Qube 2 conﬁgures itself automatically. If the network information can be conﬁgured automatically, the LCD screen displays the Qube 2’s actual IP address upon completion of the boot process.

IMPORTANT: To function properly over long periods of time, the IP address of the Qube 2 must remain ﬁxed, meaning that the DHCP server must not assign it to a different machine at a later date. Unfortunately, some DHCP servers do not honor requests for permanent IP addresses. As a result, the system or network administrator may need to assign a different (and permanent) IP address to the Qube 2. If so, you will need to change the network conﬁguration information.

Coordinate any changes to the IP address, subnet mask or gateway address with your system administrator.

Setting up the Qube 2

Conﬁguring the Qube 2 manually

IMPORTANT: In this phase, you conﬁgure only the Primary Network Interface. To complete this phase, you must know:

• the IP address assigned to the Qube 2

• the subnet mask of your network

If the Qube 2 is unable to ﬁnd a DHCP server on the network, the LCD display reads:

PRIMARY IP ADDR:

00.000.000.000

A blinking cursor appears on the second line of the LCD display. The following steps explain how to enter the required network information for the Primary Network Interface. The Secondary Network Interface is conﬁgured through the Web browser as described in the next section.

An IP address consists of four numbers, ranging from 0 to 255, separated by periods (for example, 192.168.25.77).

Entering the IP address

To enter the IP address for the Qube 2:

1. Use the arrow buttons on the LCD console to enter the IP address assigned to the Qube 2.

2. Press the button to accept the IP address.

Enter

If the IP address is valid, the following prompt appears:

PRIMARY NETMASK:

00.000.000.000

3. Enter the IP address of the netmask for your network.

4. Press the button to accept the entry.

Enter

If the netmask is valid, the following prompt appears:

ENTER GATEWAY:

00.000.000.000

see:

VERIFYING AND SAVING

Note: Selecting [C]ancel cancels the conﬁguration and the LCD screen displays: PRIMARY IP ADDR: again. You must go through the entry process again.

After verifying and saving, the Qube 2 completes the boot process. The LCD screen shows several messages in succession before displaying the IP address assigned to the Qube 2.

Conﬁguration is complete when the LCD screen displays the IP address assigned to the Qube 2, for example:

IP Address:

192.168.25.77

Setting up the Qube 2

Phase 2: Setting up with the Web browser

The remainder of the setup process is performed through a Web browser on any computer on your network. Use one of the standard browsers available (for example, Netscape Navigator or Microsoft Internet Explorer, versions 3.0 or later) to do this. Once the setup process is complete, the Qube 2 can be managed from any computer on the network that has a browser. To use the browser to set up the Qube 2, follow these steps:

1. Launch a standard Web browser on any computer connected to the network.

2. Enter the IP address of the Qube 2 (displayed on the LCD screen on the back of the Qube 2) in the URL ﬁeld of your browser, for example:

3. Then press Return (or Enter) on your keyboard.

If you conﬁgured the Qube 2 network settings successfully, the Cobalt Welcome screen appears; see Figure 7.

Network Integration

Figure 8 shows the Network Integration screen. For more information on the network settings, see “Network” on page 80.

If the Qube 2 obtained its network parameters from a dynamic host conﬁguration protocol (DHCP) server, the Network Integration screen of the Setup Wizard appears with all the ﬁelds ﬁlled in. You just need to click the NEXT button to move to the next screen.

For more information, see “Dynamic Host Conﬁguration Protocol (DHCP) server” on page 47.

On this screen, you can:

• assign a host name (for example, qube1) to the Qube 2

• enter your domain name (the ofﬁcial name that is registered with InterNIC, for example, cobalt.com)

The host name and domain name must be coordinated with your network administrator in order for you to access the Qube 2 by its name and not just by its IP address.

• enter the IP address of your domain name system (DNS) server

A DNS server maintains a list of computer names and their IP addresses. The Qube 2 needs access to this list on the DNS server in order to convert between IP addresses and names. This conversion is essential for sending and receiving email external to the Qube 2.

For more information on DNS, see Appendix D, “Domain Name System”, on page 173.

• modify user

• email

• usage data

• backup

• restore

• Page Builder

For more information, see “Personal Proﬁle” on page 144.

Using email on the Qube 2

To use all of the Qube 2’s email capabilities, you must conﬁgure the email parameter settings correctly. You must also conﬁgure your email client to send email to and retrieve email from the Qube 2.

For more information on setting up email on the Qube 2, see “Email server” on page 89.

Services on the Qube 2

Setting up your email client

Ensure that the following information is entered into your email client on your personal computer.

Note: The Qube 2 does not offer an email client. The Qube 2 is an email server that receives email addressed to a domain name. To access your email messages, you require an email client such as Microsoft Outlook or Qualcomm’s Eudora products.

1. Email address The format is either

<username>@domainname (see the note below) or

<username>@hostname.domainname

(for example, myname@qube1.cobalt.com) where:

• <username> is the user ID assigned to you (for example,

myname)

• <hostname> is the name assigned to the Qube 2 (for example,

qube1)

• <domainname> is either the official domain name that is

registered with InterNIC (for example, “cobalt.com”), or an intranet domain name specific to your network. Obtain this information from your system administrator.

Note: To use the shorter email format <username>@domainname, you must enter the domain name in the email parameters table, in the ﬁeld “Receive email addressed to these hosts/domains.”

2. SMTP server The format is hostname.domainname (for example, qube1.cobalt.com).

3. POP3 server The format is hostname.domainname (for example, qube1.cobalt.com).

4. IMAP server The format is hostname.domainname (for example, qube1.cobalt.com).

Note: Occasionally, an email application asks for an “incoming” mail server. The incoming mail server is the POP3 server.

Chapter 3

Email aliases

Each registered user on the Qube 2 must have a unique user name (for example, mary or john.smith or khoward). This user name is used to send or retrieve email.

The Email Alias feature allows you to create an arbitrary email address without creating a user account on the Qube 2. An email message addressed to the alias is forwarded to an existing email address.

If you add more than one alias for a user, enter one alias per line. You can only use lowercase alphanumeric characters, periods (.), hyphens (-) and underscores (_) in the alias.

Let us say that the XYZ Company has a Qube 2 and that the company’s domain name is xyz.com. The email addresses for the users of the Qube 2 is <username>@xyz.com. Employee Timothy Stonis has a user name of “tstonis”; his email address is “tstonis@xyz.com”.

A user can have several email aliases that point to a his or her user name. For example, Timothy Stonis can have can have the aliases “timothy@xyz.com” and “tim.stonis@abc.com”; if he were an avid soccer player, he might want to use the alias “striker@xyz.com”. All of these aliases point to his user name <tstonis> at xyz.com. Emails addressed to any of these aliases are forwarded to “tstonis@xyz.com”.

However, having a large number of aliases for each user can cause problems. If a new user is added and the user name that is automatically generated by the Qube 2 is already in use, a warning appears in the help text at the bottom of the screen, stating that <username> is already in use as a mailing list or alias. The Qube 2 does not accept the New User entry.

Following the previous example, let us say that Timothy Howard is a new employee at the XYZ Company. If he wanted to have “timothy” as his user name, the Qube 2 help text would state that “Name timothy is already in use as a mailing list or alias.”

A Qube 2 Administrator can also set up aliases such as webmaster@xyz.com, info@xyz.com, sales@xyz.com, comments@xyz.com or support@xyz.com that point to a speciﬁc user name.

Services on the Qube 2

Email relaying

Simple Mail Transfer Protocol (SMTP) service is different from Post Ofﬁce Protocol (POP), telnet and ﬁle transfer protocol (FTP) services in that SMTP does not try to authenticate a user when an SMTP connection is made. Every email server on the Internet has to be able to deliver email to you, so the email servers must be able to connect freely to send the email.

The Qube 2 accepts email if the recipient has a user account or an alias email account, or if the sending host (your client computer) is trusted to relay outgoing emails to another domain. These trusts are deﬁned by host or domain names, as well as by IP addresses and networks. A network is a range of IP addresses; a network can be as small as one IP address, but that is not very practical.

Caution: Some users advise you to open relay to all.com, .edu, .net and other top-level domain addresses. This is BAD ADVICE. Doing so allows hosts belonging to .com, .edu, .net and others to relay email through your Cobalt server. These open relays can lead to unsolicited commercial email (“spam mail”) being forwarded through your server.

Spam mail can appear as though it originated from your server and as a result, others may blacklist your server as a known spam site. If your server is blacklisted, many mail servers will not relay your email and your customers will not receive a large amount of their email messages.

Chapter 3

If you have users who access your server through the Internet, ask your Internet Service Provider (ISP) which networks are used by their remote access (dial-up) equipment.

For example, if the ISP says the network 192.168.10.5 through

192.168.10.24, then enter “192.168.10” to the “Relay email from these

hosts/domains” ﬁeld of the Email Parameters menu. If your ISP gives you a list of 30 networks used by 30 points-of-presence (POPs) (which are regional ISP ofﬁces) across the country and your clients can dial in from any of them, then you must trust all 30 networks or these users cannot send email through your Qube 2.

Note: If you do not want to allow email to be sent through the Qube 2, leave the “Relay email from these hosts/domains” ﬁeld blank.

For more information, see “Enabling the email relaying feature” on page 94.

Developing Web pages

The Qube 2 automatically provides a default home page for each individual user and each group. It also supports a broad range of Web publishing capabilities that allow both novice and expert users to build and publish custom Web pages.

Note: To access your home page, enter the URL http://<hostname>/users/<username>/ , where <hostname> is the fully qualiﬁed domain name of your Qube 2 and <username> is your user identiﬁcation on the Qube 2.

FrontPage 98 and FrontPage 2000 Server Extensions

The Qube 2 includes the FrontPage 98 and FrontPage 2000 Server Extensions, which allow users with FrontPage client applications to publish and edit Web content easily. Users can create and post Web pages using standard style templates and pre-conﬁgured tools— including form processing and search tools. It is not necessary to know anything about FTP or other ﬁle transfer protocols.

Services on the Qube 2

Using Page Builder

The Qube 2 includes Page Builder, a tool that allows you to create Web pages without having to learn how to write HTML scripts.

To enter the Page Builder tool:

• click Edit This Page at the bottom of your home page, or

• from the Personal Proﬁle screen, click Page Builder at the top

Once you are in the Page Builder tool, you can get instructions for using it by clicking the Instructions button on the left side of the screen.

For more information, see “Page Builder” on page 149.

Using an HTML editor

You can create complex Web pages using any of the standard HTML editors and the HTML publishing capabilities of many popular desktop productivity applications. You can create and link the Web pages themselves on your desktop computer, and then move them to the appropriate subdirectory in the Qube 2 through an FTP application; see “Publishing Web pages using FTP” on page 40.

CGI scripts

The Qube 2 supports common gateway interface (CGI) scripts, such as those written in Perl or C, as well as Unix shell scripts.

CGI scripts allow you to develop highly interactive, powerful Webbased applications by building server-side CGI scripts that generate Web pages in response to speciﬁc user inputs. These applications range from simple scheduling and conferencing applications to sophisticated electronic commerce solutions.

You can develop CGI scripts on your desktop machine and then transfer them to the Qube 2 through an FTP-based application that allows permission bits to be set to “Executable”.

CGI scripts must use .pl or .cgi ﬁlename extensions in order to be executed by the Web server.

Chapter 3

Use FTP to upload .cgi and .pl ﬁles; use ASCII mode to upload CGI ﬁles. Once the ﬁle is on the Qube 2, use your FTP program to make the script executable. You can also use the telnet command: chmod 775 <ﬁlename>.cgi.

The path to Perl is /usr/bin/perl .

To set the access rights for installing CGI scripts, see “Install CGI scripts” on page 104.

Publishing Web pages using FTP

After creating your Web pages, you can publish them on the Qube 2 using FTP.

Ensure that you have the following information:

• the host name or the IP address of your Qube 2

• your username and password

• a ﬁlename of your choice to save as your main page (the default ﬁlename is index.html)

Launch your FTP software and establish an FTP link to the Qube 2. Upload your HTML ﬁles. If you need help, consult the instructions for your FTP application.

By default, the ﬁles you upload using FTP are stored in your personal directory; the directory path is

/<IP address>/users/<username

> where

• <IP address> is the Qube 2’s IP address

• <username> is your user name

Note to Qube 2 Administrators: To post Web pages for the private home site, you must upload to the directory /groups/home/private/ .

Sharing ﬁles and transferring data

You can access or connect to the Qube 2 through your desktop computer as you would any other shared network volume. The Qube 2 can be mounted from any Windows or Macintosh computer — it appears as a mounted volume on your desktop computer.

Note: Windows ﬁle sharing is enabled by default on the Qube 2; Appleshare must be enabled by the user. For more information, see “Windows ﬁle sharing (SMB)” on page 97 and “Apple ﬁle sharing (AppleShare)” on page 98.

Once you have mounted the Qube 2, you can copy and move individual ﬁles and entire subdirectories to and from the Qube 2 by dragging and dropping.

The method of connecting to the Qube 2 varies, depending on your computer’s operating system.

The Qube 2 offers several methods for transferring data. Use the following guidelines to decide which method is appropriate:

• Windows ﬁle sharing (Server Message Block [SMB]) for Windows 95, Windows 98 and Windows NT.

• Apple ﬁle sharing (AppleShare) for Macintosh.

• File Transfer Protocol (FTP) on all platforms. Advanced users use FTP to transfer ﬁles.

Services on the Qube 2

Note: The ﬁle-sharing protocol is selected in the Setup Wizard or in the Control Panel screen of the Qube 2 Administrator Site. See “Control Panel” on page 87.

Chapter 3

Using Windows ﬁle sharing (SMB)

Windows-based machines use a ﬁle-sharing protocol called Server Message Block (SMB) or Common Internet File System (CIFS). Once SMB is set up, the Qube 2 appears in your Network Neighborhood as a machine named <hostname>. The <hostname> is the name that the Qube 2 Administrator assigned to the Qube 2, either in the Setup Wizard or the Control Panel screen of the Qube 2 Administrator Site.

Clicking the <hostname> icon in Network Neighborhood opens a window that provides an overview of the ﬁles and subdirectories that you can access.

Note: If you don’t see the Network Neighborhood on your computer, consult with your network administrator.

Before you begin: Windows 95 and Windows 98 users

The user name on the Qube 2 must be identical to the user name on your computer before you can access your subdirectory on the Qube 2. If necessary, restart your computer and log in as a new user, using the user name and password that are stored on the Qube 2.

Chapter 3

Using AppleShare over IP

The Qube 2 supports the use of AppleShare over IP, which means you can access your Qube 2 across an intranet or over the Internet. The Qube 2 shares its volume through AppleShare over IP by default.

If you want to connect to a remote Appleshare volume over the Internet:

1. From the Apple menu in the top left corner, select Chooser. The Chooser dialog appears.

2. In the window on the left, select AppleShare.

3. In the right corner, click Server IP Address. The Server IP Address dialog appears.

4. Enter the fully qualiﬁed host name or IP address of the Qube 2 that you want to access.

5. Click Connect.

Using FTP

File Transfer Protocol (FTP) is typically available on platforms that support Transmission Control Protocol/Internet Protocol (TCP/IP), which are the underlying protocols used by the Qube 2. FTP is designed for transferring individual ﬁles.

1. In your FTP application, enter the IP address or the host name of the Qube 2.

2. Enter your user name and password.

You are logged into the user main directory. Refer to the documentation of your FTP program for instructions on transferring ﬁles.

Note: The user root directory is not the same as the Qube 2’s root directory. Many HTML publishing programs that use FTP require full path names to transfer ﬁles.

For example, user Bill Lumbergh’s home directory is accessed through the URL ftp://<hostname.domainname>/home/users/ blumbergh/ . The “sales” group home directory is accessed through the URL ftp://<hostname.domainname>/home/groups/ sales/ .

Services on the Qube 2

Working in collaboration through discussions

Threaded discussions allow groups of individuals to develop and document a body of information on a particular topic. The discussion feature lets users collaborate without having to meet face-to-face. This feature is especially useful for individuals who are geographically dispersed or who otherwise ﬁnd it difﬁcult to meet.

Another key feature is the self-documenting nature of a threaded discussion: users can review postings to understand the who, what and why of a particular topic.

For more information, see “Working in collaboration through discussions” on page 135.

Dynamic Host Conﬁguration Protocol (DHCP) server

The Dynamic Host Conﬁguration Protocol (DHCP) allows the Qube 2 to assign automatically the network conﬁguration information (such as IP address, domain name, DNS service, subnet mask and gateway) to client computers that support DHCP, including Macintosh and Windows desktop computers.

The Qube 2 Administrator can enable the DHCP feature on the Qube 2 so that the Qube 2 is able to assign automatically the network information necessary for your desktop computer.

For more information on setting up DHCP on the Qube 2, see “Dynamic Host Conﬁguration Protocol (DHCP) server” on page 100.

What is DHCP and what are the beneﬁts?

DHCP is a way for a networked computers to obtain its TCP/IP settings when it boots up. With DHCP conﬁgured and enabled, a network administrator does not need to conﬁgure workstations manually, or modify networking settings when computers move or the network changes. This saves time and expense.

Chapter 3

What is a conﬁguration?

The Qube 2 DHCP conﬁguration includes the default Gateway, DNS servers, subnet mask and IP address from an address pool.

What are leases?

When the Qube 2 sends a conﬁguration to a requesting DHCP client, one of the DHCP options returned is the lease time. The lease time tells the DHCP client how long it can use the IP address. Before the lease time expires, the DHCP client sends a lease renewal request to the Qube 2. The Qube 2 then sends back to the client a renewed lease time, along with any other settings that have changed (for example, new IP address[es] for the DNS server).

A short lease time is useful in a network that has a limited number of IP addresses at its disposal.

How does DHCP work?

DHCP requires a client and a server. The following steps brieﬂy describe how a DHCP server provides a client with its proper TCP/IP conﬁguration:

1. When booted, a DHCP client broadcasts a request, known as a DHCP Discover, looking for a DHCP server to provide TCP/IP settings. DHCP clients are found in most TCP/IP software suites for PC, Macintosh and UNIX workstations.

Services on the Qube 2

2. The Qube 2, as a DHCP server, receives the DHCP Discover request from a client and sends a reply, known as a DHCP Offer, to the DHCP client.

3. The DHCP client looks at the DHCP Offer it has received from the Qube 2 and sends back an acknowledgment (ACK) message to the Qube 2.

4. The Qube 2 responds to the client, reserves the IP address, acknowledges the client’s acceptance of the offer and delivers the conﬁguration information.

Chapter 3

Domain Name System (DNS)

The Domain Name System (DNS) is a vital and integral part of the Internet. Setting up DNS correctly on your Qube 2 is very important. For this reason, we have created an appendix solely for explaining DNS. See Appendix D, “Domain Name System”, on page 173.

The appendix covers the following items:

• basic DNS issues

• advanced DNS issues

• a quick start guide detailing a sample setup of DNS for a Qube 2

• a brief history of the DNS service

If your network administrator is using the Qube 2 as a DNS server, you can enter the IP address of the Qube 2 into the “DNS server” ﬁeld in the TCP/IP conﬁguration on your desktop computer.

Network Address Translation (NAT)

The Network Address Translation (NAT) feature simpliﬁes and conserves IP addresses by presenting a single IP address for a private network to the public network. NAT enables private IP intranetworks that use non-registered IP addresses to connect to the Internet. NAT is both a security measure and a method of conserving IP addresses.

To enable NAT, see “Network Address Translation (NAT)” on page 84.

On the Qube 2, NAT functions as a router connecting two networks together. NAT advertises only one IP address for the entire network to the outside world. This provides additional security, since the entire internal network is hidden from the outside world behind that single IP address.

All packets transmitted from the local area network (LAN) to the Internet (including over modem connections) are masqueraded by NAT.

Services on the Qube 2

For outgoing packets, NAT translates a private IP address (an IP address that is not globally unique) on the internal network into the legal address of the secondary interface; packets are then forwarded onto the Internet.

For incoming packets, NAT does the opposite. NAT receives a packet from the Internet and translates the legal address of the secondary interface into the private IP address on the internal network.

Chapter 3

IP Firewall

A ﬁrewall is a set or ﬁltering rules used to allow or deny IP packets access to the Qube 2.

The IP Firewall option allows you to specify simple packet-ﬁltering rules, which limit access to your Qube 2. You can choose to deny or allow communication in either direction between your Qube 2 and any or all IP addresses.

For more information, see “IP Firewall” on page 106.

Internet access through high-speed serial port

The Qube 2 is equipped with a high-speed serial port to which you can connect an external modem. If you have (or can obtain) a standard point-to-point protocol (PPP) dial-up account with an Internet Service Provider (ISP), a phone line and a modem, your Qube 2 can provide Internet access for your network — no router is required.

For more information, see “Modem settings and the high-speed serial port” on page 84.

Searching for information on the Qube 2

The search function allows a user to search rapidly for a string of text in all text and HTML ﬁles on the Qube 2, including the Web pages. The search index is updated nightly.

The results are presented as a list that includes the ﬁle name and a one-line description of the ﬁles that meet the criteria.

For more information, see “Search” on page 141.

An index entry for each stored text ﬁle is created on the Qube 2 every day at 1:00 a.m. This index is a database of all of the key words used in a particular ﬁle, their location within that ﬁle and their relation to other words used in that ﬁle. For more information, see “Designating easy-toﬁnd documents” on page 153.

Managing documents

The InfoPlace Document Organizer allows users to store information — documents, images, graphics, multimedia ﬁles and URLs — on the Qube 2 in such a way that other users can ﬁnd it quickly. The InfoPlace Document Organizer is entirely Web-based; you do not have to leave your browser to use it.

The InfoPlace Document Organizer maintains a database of information about the documents it stores on the Qube 2. This database is called an Infobase. Each Qube 2 group can have several Infobases; each Infobase can be accessed and used only by the group members.

For more information, see “Managing documents” on page 151.

A mailing list with a dimmed trashcan is a mailing list created as part of a group on the Qube 2. To remove this mailing list, you must remove the corresponding group. See “Removing a group” on page 75.

To remove a mailing list:

1. On the Administrator Site screen, click Mailing Lists on the left.

2. In the list, locate the group that you want to remove.

3. Click the brown trashcan icon next to that mailing list. A

4. Click OK in the conﬁrmation dialog box. The UI on the screen

refreshes and the Mailing Lists table appears. The deleted mailing list is removed from the table.

If you change the IP address on this screen (or from the LCD console), the Qube 2 reboots.

IMPORTANT: Coordinate the network conﬁguration information with your system administrator to ensure the integrity of your network. Incorrect network settings can result in a loss of connectivity.

The Qube 2 can be set up in three different ways:

• Both intranet and Internet communication is provided through the Primary Network Interface.

• Intranet access is provided through the Primary Network Interface; Internet access is provided through the Secondary Network Interface.

• Intranet access is provided through the Primary Network Interface; Internet access is provided by modem through the high-speed serial port.

Be sure to enter the IP address of your DNS server(s) here. Otherwise, the Simple Mail Transfer Protocol (SMTP) will not work. SMTP is used for transferring electronic mail messages.

For more information on DNS, see Appendix D, “Domain Name System”, on page 173.

• Host name This is a name you assign to the Qube 2 — for

example, qube1. This field must be filled in.

• Domain name The Qube 2 requires a domain name (for

example, mydomain.com or xyz.com). The host name and domain name must be coordinated by the network administrator in order for you to access the Qube 2 by its name and not just by its IP address.

The Qube 2 Administrator must also register the domain name. Visit the Internet Corporation for Assigned Names and Numbers (ICANN) at http://www.icann.org for a list of accredited domain-name registrars.

• Primary DNS server address This is the IP address of your

primary domain name system (DNS) server. A primary DNS server maintains a list of computer names and their IP addresses. The Qube 2 needs access to this list on the primary DNS server in order to convert between IP addresses and names. This conversion is essential for sending and receiving email external to the Qube 2.

Note: The Qube 2 can serve as the DNS server and provide the host name.

Administrator Site

• Secondary DNS server address This is the IP address of your

secondary DNS server. A secondary DNS server can provide redundant DNS service to your computers. If the primary DNS server is turned off, then your Qube 2 can use the secondary DNS server with no loss of performance.

Note: Your primary DNS server and secondary DNS server cannot not be on the same server.

• Default gateway This is the IP address of the network

gateway, such as your router or firewall. A gateway address is required to connect to systems outside the local network. It may be left empty if you do not wish to access outside networks. If you are using a modem, the word modem is entered in this field.

• IP forwarding If this feature is enabled, IP packets from one

network interface can be routed to another.

3. Modify the one or all of the interface settings.

• IP address This is the IP address of the primary interface

which connects to your Intranet. This field must be filled in.

• Subnet mask This is the subnet mask of the primary interface.

The normal subnet mask for a class C network is 255.255.255.0. Yours may differ depending on the size of your network.

• Network Address Translation (NAT) If this feature is

enabled, network traffic on the internal network (the primary network interface) sent through the Qube 2 is masqueraded as if it were coming from the external interface (the modem or secondary network interface).

For more information, see “Network Address Translation (NAT)” on page 84.

• Media Access Control (MAC) address The MAC address is

the ethernet hardware address of the primary network interface. This hardware address is unique to every ethernet device; it cannot be changed.

Chapter 4

Network Address Translation (NAT)

The Network Address Translation (NAT) feature allows the Qube 2 to present a single IP address for a private network to the public network. NAT enables private IP intranetworks that use non-registered IP addresses to connect to the Internet. NAT is both a security measure and a method of conserving IP addresses.

For more information on how NAT works, see “Network Address Translation (NAT)” on page 50.

Caution: Before enabling NAT on your network, coordinate this with your system administrator to ensure the integrity of your network.

Enabling or disabling the NAT feature

To enable or disable the NAT feature on the Qube 2:

1. On the Administrator Site screen, click Network on the left. The settings tables for the network conﬁguration appear.

2. In the Interface Settings table, click the check box next to Network Address Translation (NAT). A check mark indicates that NAT is enabled.

3. Click Save Changes.

Modem settings and the high-speed serial port

Using the external modem and the second Ethernet port, the Qube 2 can also act as a router. The Qube 2 Administrator can set the phone number, user name, password and initialization string for the modem settings.

Administrator Site

The Qube 2 Administrator can also determine the connection mode between the Qube 2 and the ISP. There are three possible connection-mode settings; these settings determine how the Qube 2 uses the modem to connect to your ISP.

• “Not Used” means the Qube 2 does not connect at all.

• “Dial-on-demand” means the Qube 2 connects only when there is trafﬁc that is destined for an external network.

• “Always Connected” means the Qube 2 is connected at all times.

The setting you choose depends on your phone line and access charges.

• If you have a dedicated phone line for Internet access, then you can choose “Always Connected.”

• If the phone line you use for Internet access is also used for voice or fax communication, or if your Internet access is charged by the minute, then choose “Dial-on-demand.” The modem accesses the Internet only when a user requires Internet access.

Note: If you choose Dial-on-demand, your ﬁrst attempt to access the Internet may time out before your modem can establish a connection to your ISP. If this happens, wait for a short period, then try again.

• Connection mode The connection mode determines when the

modem connects to the PPP account.

• Phone number This is the phone number to dial to access the

PPP account for the given user. Do not include spaces in the phone number.

• User name This is the user name used to log into the

PPP account. This is set by the provider of the PPP account, for example your ISP.

• New password This is the password used to authenticate the

PPP connection for the given user. Enter the password twice for verification.

• Modem initialization string (optional) Just before dialing, the

initialization string is sent to the modem to initialize the modem, for example ATZ. The Qube 2 brings the modem to its default factory settings.

• Local IP address (optional) This is the IP address for the

PPP link if you are using a fixed IP address assigned by your provider. If the IP address for the PPP link is assigned dynamically by the connecting server, leave this field blank.

• Local subnet mask (optional) This is the netmask for the

PPP link if you are using a fixed IP address assigned by your provider. If the IP address for the PPP link is assigned dynamically by the connecting server, leave this field blank.
