Installing the DNCA software

Use the following information to install the DNCA software to your physical server or virtual machine. If you are deploying your Network Capture Application to a cloud-based environment, refer to the installation procedures for those environments.

Procedure

  1. Log in to the server by using the root account.
    Note: The installation must be run as root.
  2. Open a command prompt.
  3. Enter yum install Discover-DNCA-<nn.n.n>-<rrr>.<distro>.<architecture>.rpm to install the DNCA software.

    Where:

    • <nn.n.n> is the build version number.
    • <rrr> is the RPM revision number. The revision numbers is usually a single digit number.
    • <distro> is an identifier for the Linux™ distribution, such as "RHEL n" for Red Hat Enterprise Linux release n.
    • <architecture> is i686, x86_64.

    By default, the DNCA software is installed in /usr/local/dncauser. You specify the alternate directory by using the rpm command's --prefix option along with the installation and upgrade commands.

    The following are some sample rpm invocations.

    rpm -i --prefix=/opt/Discover Discover-DNCA-<nn.n.n>-<rrr>.<distro>.i386.rpm
    rpm -U --prefix=/home/Discover Discover-DNCA-<nn.n.n>-<rrr>.<distro>.i386.rpm

    When you do not use the --prefix option during an install or upgrade, RPM uses the default installation directory that is specified in the DNCA package file, which is /usr/local/dncauser. Once you relocate a package, you must specify the alternate directory when you apply upgrades so that the package correctly checks for and updates previous installations.

Results

When the files are extracted from the rpm package, follow the post-installation checklist to validate the installation and begin the configuration process.
