How to Enable or Disable SSH on VMware ESXi via Web GUI, vSphere Web GUI (vCenter), vSphere Client and Shell Console

Posted in Virtualization & VM Backup

SSH access to VMware’s ESXi server is by disabled by default however there are many reasons where SSH might be required. VMware and System administrators often find the need to perform advanced administrative tasks that require SSH access to the ESXi host. For example, deleting or reloading a VM with an Invalid Status can only be performed via SSH.

In this article, we’ll show you how to enable SSH on your ESXi host with just a few simple steps. This task can be achieved via the ESXi Web GUI, vSphere Web GUI (vCenter) vSphere client or ESXi console. We’ll cover all three methods.

Execution Time: 5 minutes

Security Tip: If your ESXi host management IP is not protected or isolated from the rest of the network, it is advisable to enable SSH on an as-needed basis.

Enabling and Disabling SSH Console on VMware ESXi via Web GUI

Log into your ESXi server and select the host from the Navigator window. Next, go to Action > Services and select the Enable Secure Shell (SSH) menu option:

vmware esxi enable ssh

This will immediately enable SSH. To disable SSH, repeat the same steps. You’ll notice that the Disable Secure Shell (SSH) option is now available:

vmware esxi disable ssh

Enabling and Disabling SSH on VMware via vSphere Web GUI Client (vCenter)

For those with a VMware vCenter environment, you can enable SSH for each ESXi host by selecting the host and then going to Manage > Settings > Security Profile > Edit.  In the pop-up window, scroll down to SSH Server and tick it. Optionally enter the IP address or network(s) you require to have SSH access to the host:

vmware esxi enable ssh vsphere web gui
