Before you begin

Install NetScaler BLX

  1. Untar the NetScaler BLX installation package and then change the working directory to the extracted NetScaler BLX installation directory.
    tar -xvzf blx-deb-<release number>-<build-number>.tar.gz

    cd <path to the extracted NetScaler BLX installation directory>
    Sample output:
    The following sample output shows that the NetScaler BLX installation package blx-deb-14.1-4.42.tar.gz downloaded to the /var/blxinstall directory of the Linux host is untared. Then, the working directory is changed to the extracted directory blx-deb-14.1-4.42.
    # cd /var/blxinstall

    # tar -xvzf blx-deb-14.1-4.42.tar.gz

    # cd blx-deb-14.1-4.42

    # pwd
    /var/blxinstall/blx-deb-14.1-4.42
  2. Run the following command to install NetScaler BLX.
    apt install ./blx*.deb
    Note:
    Installation of NetScaler BLX might fail on a Debian-based Linux host, running Ubuntu version 18 or later, with the following dependency error:
    The following packages have unmet dependencies: blx-core-libs:i386 : PreDepends: libc6:i386 (>= 2.19) but it is not installable
    Workaround: Run the following commands in the Linux host CLI before installing NetScaler BLX:
    • dpkg --add-architecture i386
    • apt update
    • apt install libc6:i386
  3. This is an optional step. To use the custom monitor feature, you must install perl(Authen::NTLM) manually by using Comprehensive Perl Archive Network (CPAN) on the system before proceeding to use nsall.pl and nsntlm-lwp.pl scripts.
    # cpan install Authen::NTLM
  4. Check the status of NetScaler BLX by running the following command:
    systemctl status blx
    By default, NetScaler BLX is in an inactive state.
To uninstall the NetScaler BLX from the Linux host:
  • Run the apt remove blx command on the Linux host to uninstall NetScaler BLX and keep the NetScaler BLX configuration file.
  • Run the apt purge blx command on the Linux host to uninstall NetScaler BLX and remove the NetScaler BLX configuration file.
    Note:
    The Linux host might display warning messages that some NetScaler BLX-related system files are not removed. But, all the NetScaler BLX files are removed when you run the apt purge blx command.
