Issue/Introduction

  • Cluster warning for ESXi Shell and SSH appears on an ESXi 5.x host.
  • ESXi host displays these errors:
     
    • ESXi Shell for the Host has been enabled
    • SSH for the host has been enabled

Cause

Note: This article pertains vSphere 6.x & vSphere 5.x. For vSphere 4.x, see Cluster warning shown in vCenter Server when Remote Tech Support Mode (SSH) or Local Tech Support Mode is enabled (1016205).

In vSphere 6.x, 5.x, you can enable both Remote SSH and the ESXi Shell for management of hosts from the vSphere Client, vSphere Web Client and from the Direct Console User Interface.

These messages that appear with a yellow exclamation mark is a proactive security measure and inform administrators that remote access is enabled for the server.

Disabling Remote SSH and ESXi Shell removes the messages from the host.
