3    Installing the Kit

If you are not currently running Tru64 UNIX Version 5.1A, you must install Version 5.1A before installing this version of the kit. Do the following:

  1. Back up your system.

  2. Install Tru64 UNIX Version 5.1A.

    Caution

    Because of conflicts between files installed by the Mobile IPv6 kit and files installed by the patch kit, do not install any patches after the installation has finished.

You must also configure your system as an IPv6 host node or a router. See the Network Administration: Connections manual for more information.

3.1    Installing the Kit

After you create the /usr/kits directory and copy the compressed file to the directory, do the following to install the kit:

  1. Change to the /usr/kits directory.

    # cd /usr/kits
    

  2. Uncompress the file by using the following command:

    # gunzip -c mobileipv6demo.tar.gz | tar xvpf -
    

  3. Change to the mobileipv6 directory.

    # cd mobileipv6
    

  4. Install the Mobile IPv6 files with the following command:

    # ./installmobileipv6demo
    

    Enter 1 to select Kit Installation.

    Choose which role this system will have:

    Will this system be a Home Agent or Correspondent Node? [H/C]
    

    Enter H for the home agent or enter C for the correspondent node.

    If any errors occur during this step, correct them before going to step 5.

  5. Build a new kernel by using the following command:

    # doconfig -c SYSTEM_NAME
    

    SYSTEM_NAME is the name of your system, in uppercase letters.

  6. Move the new kernel to the root directory, making sure that the original kernel is saved.

    # mv /vmunix /vmunix.save
    # mv /sys/SYSTEM_NAME/vmunix /vmunix
    

  7. Reboot the system. Make sure there are no other users on the system. Use a command similar to the following:

    # shutdown -r +5 "Completing Tru64 UNIX Mobile IPv6 Installation..."
    

The system is now ready to function as either a home agent or a correspondent node.

3.2    Removing the Kit

If you need to remove the kit, do the following:

  1. Change to the /usr/kits/mobileipv6 directory.

    # cd /usr/kits/mobileipv6
    

  2. Remove the Mobile IP files with the following command:

    # ./installmobileipv6demo
    

    Enter 2 to select Kit Removal. This restores the original files.

  3. Restore the original kernel with the following command:

    # mv /vmunix.save /vmunix
    

  4. Reboot the system. Make sure there are no other users on the system. Use a command similar to the following:

    # shutdown -r +5 "Completing Tru64 UNIX Mobile IPv6 Removal..."
