    Welcome Page

    Use this program to install TCP/IP 4.1 for OS/2. Before doing so, please review the README.TXT file packaged with this product.

    Install this release on any of the following operating systems:

    Be sure the drive containing your SWAPPER.DAT file has plenty of available disk space (40 Mb or more, depending on your machine) in the event OS/2 may need to occasionally swap the TCP/IP Installation Program.

    Two Installation Paths

    This program lets you install TCP/IP two ways.

    Users unfamiliar with installing products like TCP/IP can select a fast path where most of the installation choices are made for them. Users can accept these default choices or change them. This is the Guided Path.

    Users comfortable with installing products like TCP/IP can select a path where more setup and configuration choices are available. On this path users can supply TCP/IP Configuration Notebook information such as IP address, host name, subnet mask, router, domain, and name server. Any basic TCP/IP configuration information previously available on the computer is displayed by TCP/IP and users can modify it. This is the Advanced Path.

    Beginning Your Installation

    To begin installation, click either the Guided Path or Advanced Path push button. Accept or change the default entries on each page. Assistance is always available; just click Help (the question mark button at the bottom center of your browser window). Actual installation of files will not begin until you click the Install button at the bottom of the Ready to Install page.

    To exit the TCP/IP Installation Program at any time before then, double-click the browser application icon at the upper left corner of your browser window.

    Note: This release of TCP/IP lets you configure all the TCP/IP configuration parameters at installation time using CID. See the SAMPLE.RSP file shipped in the root installation directory for details on using CID.

    The push buttons available from this page are:

    Guided Path
    Use the installation fast path, which provides most information for you.

    Advanced Path
    Use the installation path that has the most setup and configuration options.

    Guided Path

    Use this installation path if you are unfamiliar with installing products like TCP/IP. The Guided Path is a fast path where most installation choices are made for you. The Guided Path will not prompt you to change your existing TCP/IP configuration information. TCP/IP gathers any information it needs from your computer.


    Component Selection Page

    Use this page to tailor your TCP/IP-related components. Some components on this page are preselected. You can change any selection by checking or unchecking a component's check box. The default is to install the same TCP/IP components that already exist on your computer. If TCP/IP is not present, the default is to install only the TCP/IP base applications.

    The fields on this page are:

    TCP/IP Base Applications
    Check the box to install, uncheck the box to decline installation.

    DHCP/DDNS Server
    This check box is enabled only on Warp Server 4 and Warp Server SMP computers. This check box is disabled on client computers.

    Check the box to install, uncheck the box to decline installation.

    DHCP, or Dynamic Host Configuration Protocol, automatically assigns an IP address and configures TCP/IP every time a client computer starts. The Dynamic Domain Name System enables clients to dynamically and directly register their names and addresses in DDNS tables, ending the need for a network administrator to do this manually.

    Choose this selection if your computer is a DHCP or DDNS server.

    Note: When you check this box, both DHCP and DDNS servers will be installed on the same computer.

    Also note: If you are updating your server, you may want to have your clients update MPTS as well. The new DHCP/DDNS Client code is shipped with MPTS.

    Personal Communications Entry V4.1
    This check box is disabled when you have Personal Communications Fullpack installed on your computer.

    Check the box to install, uncheck the box to decline installation.

    Personal Communications Entry is an emulator that provides PC/3270 terminal emulation. Choose this selection if your computer does not already have S/390 host session capability, and you want it.

    Virtual Private Network (VPN)
    Check the box to install, uncheck the box to decline installation.

    Select VPN only if your business's intranet uses IBM Firewall 3.1 (or later) and you want to set up a virtual private network.

    TCP/IP for OS/2 uses the IBM Secure Remote IP Client program, together with IP Security, to configure a VPN for this computer. The VPN provides a secure communications channel from a remote computer across the Internet to an intranet protected by the IBM Firewall.

    As a result, you can use the Internet rather than costly switched phone lines and modems to securely connect to your business's private intranet from a remote location, such as your home.

    When VPN is enabled, IP security is also enabled.

    Drive Selection Page

    Use this page to select the drive on your computer where the TCP/IP for OS/2 files will be stored.

    Drive choices are displayed on the left side of the page. Your used, available, and required disk space information for all available drives is displayed on the right.

    On the left, your default TCP/IP drive is preselected. The default is your current TCP/IP drive if you have one; otherwise, the default drive is the drive where OS/2 is installed. The TCP/IP Installation Program will place its files on the default drive, unless you specify otherwise. Most users can accept the default drive.

    If you select another drive for this installation, the TCP/IP Installation Program will first verify that the new drive has enough disk space for the installation. If so, any existing TCP/IP files will be moved to the new location and installation will occur in directory \TCPIP on the new drive. If not, installation will default to your current TCP/IP drive and directory if you have one; otherwise, to directory \TCPIP on the drive where OS/2 is installed. The default drive used will be displayed as the selected drive in the drive selection box.

    The fields on this page are:

    TCP/IP Drive
    Select the drive where you want this version of TCP/IP installed, or accept the default. The default location is your current TCP/IP drive and directory if you have one; otherwise, directory \TCPIP on the drive where OS/2 is installed. If you select a new drive for TCP/IP, it will be installed in directory \TCPIP on that drive. In the event the new drive cannot be used, the default drive will be used.

    Administrator Password
    Set a password to give an administrator working from a remote computer access to the Java-enabled TCP/IP graphical user interfaces on this computer. These interfaces are used for configuring TCP/IP functions and dynamic IP servers, either locally or remotely.

    When these TCP/IP interfaces are started, remote users are prompted for the administrator password (local users are not prompted). You can set this password here or, after TCP/IP installation, use the ADMIN_PW.CMD utility to set or reset the password.

    The password must be at least five characters in length, and is case-sensitive.

    Install
    * Figure instarro not displayed.
    Begin TCP/IP file installation. When you click Install, a window will display a progress indicator showing the current percent of installation done. The names of the files being installed are also displayed.

    Advanced Path

    Use this installation path if you are comfortable installing products that require supplying some of your own information. Chosing this path gives you more setup and configuration choices than the Guided Path. You can provide or overwrite information like your IP address, host name, subnet mask, router, domain, and name server. Information already available from your system is gathered for you by TCP/IP, but you can modify it.


    Component Selection Page

    Use this page to tailor your TCP/IP-related components and provide TCP/IP configuration information.

    Component choices are displayed on the left side of the page. Your used, available, and required disk space information for all available drives is displayed on the right.

    Some choices on the left are preselected. You can change any selection by checking or unchecking a component's check box. The default is to install the same TCP/IP components that already exist on your computer. If TCP/IP is not present, the default is to install only the TCP/IP base applications.

    Also on the left you have the option to change the installation path for the TCP/IP base applications, and to configure them. To do so, click Configure and verify or modify the available entries. Do this before clicking Forward at the bottom of the page, unless you are actually ready begin installing files. (Clicking Forward advances you to the Ready to Install page.)

    The fields on this page are:

    TCP/IP Base Applications
    Check the box to install, uncheck the box to decline installation.

    Drive
    Select the the drive where you want this version of TCP/IP installed, or accept the default. The default is your current TCP/IP drive and directory if you have one; otherwise, the directory \TCPIP on the drive where OS/2 is installed.

    If you specify a new drive for TCP/IP, any existing TCP/IP files will be moved to the new location and installation will occur in directory \TCPIP on the new drive--provided the drive has enough disk space for the installation. In the event the new drive cannot be used, the default drive will be used.

    If the default is used, it will be displayed as the selected drive in the drive selection box.

    TCP/IP Base Applications Window

    Use this window to configure the TCP/IP base.

    Providing the information in this window is optional. You can always specify it after installation, in your TCP/IP Configuration Notebook.

    The selections and fields in this window are:

    Configure Manually
    Select this button to configure a LAN interface yourself. If you select this button, you must complete the IP Address and Subnet Mask fields.

    The fields you can configure yourself are:

    IP Address
    Specify a dotted-decimal Internet Protocol address. A dotted-decimal address consists of four numeric fields, ranging from 0-255, separated by periods. For example, 9.67.43.126 is an IP Address.

    Host Name
    Specify the hostname portion of the fully qualified host name of your computer. A fully qualified host name includes both host and domain names, as follows:
    poe.eng.mit.edu
    
    The host name is poe and the domain name is eng.mit.edu.

    For the current field enter only the host name, which in this case would be:

    poe
    

    Subnet Mask
    Specify a dotted-decimal subnet mask. The dotted-decimal subnet mask consists of four numeric fields, ranging from 0-255, separated by periods. For example, 255.255.255.0 is a subnet mask.

    The Subnet Mask field indicates how much of the local address portion of the IP address to reserve for a subnetwork address.

    TCP/IP can divide a single network into multiple logical networks. For example, an organization can have a single IP address that is known to users outside the organization, but it can configure its local address portion of the IP address into a subnetwork number and a host number to represent different departments within the organization.

    Router
    Specify the dotted-decimal IP address of the default router to be used. A dotted-decimal address consists of four numeric fields, ranging from 0-255, separated by periods. For example, 253.253.253.0 is a default router address.

    Domain

    Specify the domain where your host resides, including all subdomains and the root domain, separated by periods.

    A domain name is the second part of a fully qualified host name; for example:

    poe.eng.mit.edu
    
    The host name is poe and the domain name is eng.mit.edu.

    For the current field enter only the domain name, which in this case would be:

    eng.mit.edu
    

    As an alternative, you can use the TCP/IP Configuration Notebook to specify a LAN domain search list of domains to be searched. If you specify both a domain name and a domain search list, the search list will be used.

    Name Server
    Specify the dotted-decimal IP address of the primary server to be used to resolve domain names to IP addresses. A dotted-decimal address consists of four numeric fields, ranging from 0-255, separated by periods. For example, 9.14.3.101 is a name server address.

    Configure Using DHCP
    Select this button to configure your computer automatically for TCP/IP, using DHCP.

    DHCP, or Dynamic Host Configuration Protocol, automatically assigns an IP address and configures TCP/IP every time you start your computer. Choose this selection if your computer has access to a DHCP server.

    The selections available for configuring using DHCP are:

    I want to use DDNS
    Select this button if you are in a dynamically updatable zone. (If you are unsure, ask your LAN administrator.)

    By selecting DDNS, the Dynamic Domain Name System will enable your computer to dynamically and directly register its name and address in DDNS tables. This ends the need for a network administrator to do the updates manually.

    I don't want to use DDNS
    Select this button if you are not in a dynamically updatable zone. If the button is selected, your current host name will not be updated by the DDNS server.

    The push buttons available from this window are:
