Before you begin

  • Make sure that NetScaler BLX is up and running on the Linux host. For more information on how to start NetScaler BLX, see Start NetScaler BLX.

Password requirements

  • When you log in with the default admin (nsroot) password for the first time, NetScaler BLX prompts you to change the password for security reasons. After changing the password, you must save the configuration. If the configuration is not saved and the NetScaler BLX restarts, you must log in with the default password again.
  • Strong password enforcement is enabled by default in NetScaler BLX for all local system users. The default minimum length for a strong password is four characters. A strong password must contain the following:
    • One lower case character.
    • One upper case character.
    • One numeric character.
    • One special character from the set (!, @, #, (, ), $, %, \^, &, and *).
Note:
Make sure that the password for each system user of NetScaler BLX matches the strong password criteria.

Access NetScaler BLX and configure NetScaler features using the NetScaler CLI

NetScaler BLX has a command line interface (CLI) where you can run NetScaler CLI commands to configure NetScaler features on NetScaler BLX.
You can remotely access the NetScaler BLX by connecting through the secure shell (SSH) from a workstation.
To access NetScaler BLX by using the NetScaler CLI:
  1. Open an SSH client from your workstation.
  2. Specify the IP address and port on which the CLI of NetScaler BLX is available and connect to the CLI.
  3. Log in to NetScaler BLX using your NetScaler BLX login credentials.
For more information about NetScaler CLI commands, see the NetScaler Command Reference Guide.

Access NetScaler BLX and configure NetScaler features using the NetScaler GUI

The NetScaler GUI includes a configuration utility and a dashboard utility.
The following table lists the default IP address and port on which the NetScaler GUI is available:
Access type IP address and port to access NetScaler GUI
HTTP <NetScaler IP address (NSIP)>:80
HTTPS <NetScaler IP address (NSIP)>:443
You can modify these default port numbers in the blx.conf file. You must restart the NetScaler BLX after you modify the blx.conf file.
Note:
  • You can change the default management port numbers of HTTP and HTTPS using the set ns param command. But, when you use the unset ns param or clear config full command, the default port numbers are not restored.
The NetScaler GUI prompts you for NetScaler BLX login credentials. After you log in to the GUI, you can configure NetScaler features using the NetScaler GUI.

Access NetScaler BLX using the GUI

  1. Open a web browser.
  2. Use one of the following access methods:
    • For HTTP access, type the following in the URL field: <NetScaler BLX IP address (NSIP)>:<HTTP port>
    • For HTTPS access, type the following in the URL field: <NetScaler BLX IP address (NSIP)>:<HTTPS port>
  3. On the login page, enter your NetScaler BLX login credentials and click Login.

Access NetScaler BLX and configure NetScaler features using the NITRO APIs

You can use the NetScaler NITRO API to configure NetScaler features. NITRO exposes its functionality through Representational State Transfer (REST) interfaces. Therefore, NITRO applications can be developed in any programming language. Also, for applications that must be developed in Java or .NET or Python, NITRO APIs are exposed through relevant libraries that are packaged as separate Software Development Kits (SDKs).
Similar to the NetScaler GUI, the NITRO API requests must be sent to the HTTP or HTTPS port of the NetScaler BLX management IP address.

Access NetScaler BLX

  • To configure NetScaler BLX by using the NITRO API in a web browser, type:
    http://<NetScaler BLX IP address (NSIP)>:<HTTP port>/nitro/v1/config/<resource-type>
    https://<NetScaler BLX IP address (NSIP)>:<HTTPS port>/nitro/v1/config/<resource-type>
  • To retrieve statistics of NetScaler BLX by using the NITRO API in a web browser, type:
    http://<NetScaler BLX IP address (NSIP)>:<HTTP port>/nitro/v1/stats/<resource-type>
    https://<NetScaler BLX IP address (NSIP)>:<HTTPS port>/nitro/v1/stats/<resource-type>
