SFHA Solutions 6.2: Configuring secure shell or remote shell communication between nodes when installing Symantec products

Level 4
Employee Accredited

To install and configure Symantec software, you need to establish secure shell (ssh) or remote shell (rsh) communication with superuser privileges between the nodes where the installer is running and the target nodes.
You can install products to remote systems using either ssh or rsh. Symantec recommends that you use ssh as it is more secure than rsh.
You can set up ssh and rsh connections in the following ways.

  • You can use UNIX shell commands to manually set up the connection. Using this method, you can log into and execute commands on a remote system. You can run the installer directly to set up the ssh/rsh connection interactively during the install procedure.  You first create a Digital Signature Algorithm (DSA) key pair. From the key pair, you can append the public key from the source system to the authorized keys file on the target systems.
  • You can run the installer -comsetup command. Using this method, you can interactively set up the ssh and rsh connections using the installer -comsetup command.
  • You can run the password utility. If you want to run the installer with the response file present in your own scripts, then the ssh connection should be set up prior to running installer. The password utility,, is bundled in the Symantec Storage Foundation and High Availability (SFHA) Solutions 6.2 release under the scripts directory. You can run the utility in your script to set up the ssh and rsh connection automatically.

 Both the script-based and web-based installers support establishing passwordless communication.
