Access a NetScaler

A NetScaler appliance has both a command line interface (CLI) and a graphical user interface (GUI). The GUI includes a configuration utility for configuring the appliance and a statistical utility, called Dashboard. For initial access, all appliances ship with the default NetScaler IP address (NSIP) of and default subnet mask of You can assign a new NSIP and an associated subnet mask during initial configuration.

If you encounter an IP address conflict when deploying multiple NetScaler units, check for the following possible causes:

  • Did you select an NSIP that is an IP address already assigned to another device on your network?
  • Did you assign the same NSIP to multiple NetScaler appliances?
  • The NSIP is reachable on all physical ports. The ports on a NetScaler are host ports, not switch ports.

The following table summarizes the available access methods.

Access Method Port Default IP Address Required? (Y/N)
CLI Console N
CLI and GUI Ethernet Y

Command line interface

You can access the CLI either locally, by connecting a workstation to the console port, or remotely, by connecting through secure shell (SSH) from any workstation on the same network.

Log on to the Command Line Interface through the Console Port

The appliance has a console port for connecting to a computer workstation. To log on to the appliance, you need a serial crossover cable and a workstation with a terminal emulation program.

To log on to the CLI through the console port, follow these steps:

  1. Connect the console port to a serial port on the workstation. For more information, see Connect the console cable.
  2. On the workstation, start HyperTerminal or any other terminal emulation program. If the logon prompt does not appear, you may need to press ENTER one or more times to display it.
  3. Log on by using the administrator credentials. The command prompt (>) appears on the workstation monitor.

Log on to the Command Line Interface by using SSH

The SSH protocol is the preferred remote access method for accessing an appliance remotely from any workstation on the same network. You can use either SSH version 1 (SSH1) or SSH version 2 (SSH2.)

If you do not have a working SSH client, you can download and install any of the following SSH client programs:

These programs have been tested by the Citrix NetScaler team, which has verified that they work correctly with a NetScaler appliance. Other programs may also work correctly, but have not been tested.

To verify that the SSH client is installed properly, use it to connect to any device on your network that accepts SSH connections.

To log on to a NetScaler appliance by using an SSH client, follow these steps:

  1. On your workstation, start the SSH client.
  2. For initial configuration, use the default IP address (NSIP), which is For subsequent access, use the NSIP that was assigned during initial configuration. Select either SSH1 or SSH2 as the protocol.
  3. Log on by using the administrator credentials. For example.
login as: nsroot

NetScaler GUI


A certificate-key pair is required for HTTPS access to the Citric ADC GUI. On the ADC, a certificate-key pair is automatically bound to the internal services. On an MPX or SDX appliance, the default key size is 1024 bytes, and on a VPX instance, the default key size is 512 bytes. However, most browsers today do not accept a key that is less than 1024 bytes. As a result, HTTPS access to the VPX configuration utility is blocked.

Additionally, if a license is not present on an MPX appliance when it starts, and you add a license later and restart the appliance, you might lose the certificate binding.

Citrix recommends that you install a certificate-key pair of at least 1024 bytes on a NetScaler for HTTPS access to the GUI, and that you install an appropriate license before starting the ADC.

The graphical user interface includes a configuration utility and a statistical utility, called Dashboard, either of which you access through a workstation connected to an Ethernet port on the appliance.

The system requirements for the workstation running the GUI are as follows:

  • For Windows-based workstations, a Pentium 166 MHz or faster processor.
  • For Linux-based workstations, a Pentium platform running Linux kernel v2.2.12 or above, and glibc version 2.12-11 or later. A minimum of 32 MB RAM is required, and 48 MB RAM is recommended. The workstation should support 16-bit color mode, KDE and KWM window managers used in conjunction, with displays set to local hosts.
  • For Solaris-based workstations, a Sun running either Solaris 2.6, Solaris 7, or Solaris 8.

Your workstation must have a supported web browser to access the configuration utility and Dashboard.

The following browsers are supported.

Operating System: Windows 7

Browser: Internet Explorer (version 9, 10, and 11), Mozilla Firefox (version 3.6.25 and above), Google Chrome (latest).

Operating System: Windows 64 bit

Browser: Internet Explorer (version 8, 9, 10, and 11), Google Chrome (version latest)

Operating System: MAC Browser: Mozilla Firefox (version 3.6.25 and above), Safari (version 5.1.3 and above), Google Chrome (version latest)

Use the NetScaler GUI

Once you log on to the configuration utility, you can configure the appliance through a graphical interface that includes context-sensitive help.

To log on to the GUI, follow these steps:

  1. Open your web browser and enter the NetScaler IP (NSIP) as an HTTP address. If you have not yet set up the initial configuration, enter the default NSIP ( The Citrix Logon page appears.

    Note: If you have two NetScaler appliances in a high availability setup, make sure that you do not access the GUI by entering the IP address of the secondary NetScaler appliance. If you do so and use the GUI to configure the secondary appliance, your configuration changes will not be applied to the primary NetScaler appliance.

  2. In the User Name text box, type nsroot.

  3. In the Password text box, type the administrative password you assigned to the nsroot account during initial configuration and click Login. The Configuration Utility page appears.

    If you need to access the online help, select Help from the Help menu at the top right corner.

Use the Statistical Utility

Dashboard, the statistical utility, is a browser-based application that displays charts and tables on which you can monitor the performance of a NetScaler appliance.

To log on to Dashboard, follow these steps:

  1. Open your web browser and enter the NSIP as an HTTP address. The Citrix Logon page appears.
  2. In the User Name text box, type nsroot.
  3. In the Password text box, type the administrative password you assigned to the nsroot account during initial configuration.
