Installing the Network Shell (Linux and UNIX)

This topic provides instructions for installing the Network Shell on a Linux or UNIX computer.

To perform a silent installation of the Network Shell, see Using-silent-mode-to-install-the-Network-Shell-Linux-and-UNIX.

Before you begin

Linux platforms on which you plan to install the Network Shell must have the libtermcap.so.2 shared library installed. Install the shared library before installing the Network Shell. For more information, see Requirement for installing the Application Server or Network Shell on Linux.

To install only the Network Shell

1. Navigate to the directory containing installation files and run the installation script for Network Shell. (Script names follow the convention: NSHversion-platform.) You must execute the installation from a root shell. Do not execute the installation script from a non-root account.
   The following message is displayed:
   Please choose the installation directory. [/opt/bmc/bladelogic]
2. To install Network Shell in /opt/bmc/bladelogic, press Enter. Or enter another directory path.
   A message is displayed letting you choose a language for the installation program.
3. Enter the number representing the language that you want to use for the installation.
   A welcome message is displayed.
4. Press Enter.
   The following message is displayed:
   Do you agree to the terms of the license agreement (y for Yes) ?

5. Enter y.
   The following message is displayed:

   ============== Select Installation Components =============
   Server Utilities
   1 - RSCD Agent
   Client Utilities
   3 - Network Shell
   9 - Start the installation
   A - Select all components
   Select component

6. Enter 3.
   A plus sign (+) appears next to Network Shell to indicate you have chosen to install it.

   To install both the RSCD agent and Network Shell, choose the A - Select all components option.

7. Enter 9.
   A message is displayed, asking you if you want to continue.
8. Enter y. The following message is displayed:
   Do you wish to install the default .nsh resource files into /etc/skel (y/n)?
   These files make it easier to set up Network Shell as a logon shell. This prompt is not displayed when installing on an AIX platform.
9. Enter y.
   
   If the installation program detects that the computer does not include a hardware device for generating random numbers, the installation program explains why TrueSight Server Automation needs random numbers.
   TrueSight Server Automation uses random numbers to encrypt communication securely. If a server includes a hardware device for generating random numbers (usually at /dev/random or /dev/urandom), but that device is not functioning properly, the installation program advises you to install a patch to correct the problem. BMC recommends this approach for setting up random number support on a server.
   The installation program gives you the option to install an entropy gathering daemon (EGD) that performs a variety of actions to generate random data in a secure manner. The TrueSight Server Automation EGD is called the Pseudo Random Number Generator Daemon (PRNGD).
   The installation program displays the following message:
   Do you wish to install the TrueSight Server Automation PRNGD (y/n)?
10. Do one of the following:
    • To install PRNGD, enter y. This is the default.
    • If you do not want to install PRNGD, enter n.
      A message warns that the RSCD agent will not be started because no suitable random number generator was found and you have chosen to install and configure a working device of your own. The RSCD agent can be started when that has been done.
      Installation is complete.
