Both /etc/issue.net and /etc/issue are used to display a banner to SSH users before the login prompt.
Such banners may cause a Mammoth upgrade to fail. As such these banners need to be disabled prior to upgrade and must be disabled for the duration of the Mammoth upgrade.
The banner can be restored when the upgrade completes.
If such banners are active:
1. Logging into a node via ssh issues a message like below before the login prompt.
To disable a banner in "/etc/issue.net" and "/etc/issue" raised during an ssh login or dcli command, follow the steps in the Solution section below.
