Customize a login banner
About this task
The /etc/issue file contains a login banner message or system identification, which appears before the login prompt. A login banner can be used for any informational purpose, but is most often used to warn users about unauthorized or improper use of the system.
- Log in to the CLI with your username and password. You must have root privileges to access the /etc/issue file.
- Edit the /etc/issue file using vi or another text editor.
EMC suggests you add an extra carriage return at the end of the banner message.
Use spaces, tabs, and carriage returns to format the message. In general, you should limit the size of the message to no more than a single screen.
NOTE: Because the login banner appears with the login prompt, do not include any sensitive information in the banner message. - Log in to the CLI or Unisphere to view the login banner and verify your changes.
NOTE: You can also customize the login banner using
. You must have root privileges to access the Login Banner field. The
VNX Release Notes describe how to log in to Unisphere as root.
