Setup SSH Server Key

Overview

This function sets up the SSH server key that is used when encrypting communication using Secure SHell (SSH).

SSH is used when accessing from CLI.

Caution

  • After the SSH server key setting has been changed, the information must be updated in the storage system before accessing from CLI via the SSH connection. Log out from CLI and wait a few minutes before logging in again.

Note

  • The SSH server key is specified in the factory settings (key length: 2048 bits).

  • Even if the SSH server key setting are changed, a setting PC that logs in to CLI via a Telnet connection is not affected.
