Before you begin

Ensure that the NetScaler BLX package is available on the Linux host. For information on how to download NetScaler BLX, see Download the NetScaler BLX package on the Linux host.
Ensure that the Linux host has internet access to install the necessary dependencies. For more information about auto-installed dependencies, see Auto-installed dependencies for NetScaler BLX.
Ensure that you have root or sudo privileges to install NetScaler BLX on the Linux host.

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-13.1-51.15.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-13.1-51.15.
# cd /var/blxinstall # tar -xvzf blx-deb-13.1-51.15.tar.gz # cd blx-deb-13.1-51.15 # pwd /var/blxinstall/blx-deb-13.1-51.15
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
Check the status of NetScaler BLX by running the following command:

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.
