From your terminal of choice, logging in to an ESXi host is as simple as specifying the connection protocol, in this case "SSH" followed by the "user name" @ IP Address of the intended host.

If you have created another user and/or disabled logging in as root. Then you'll need to replace "root" with the "user_name" @ IP address. Example shown below, to establish the connection process, press the ENTER key. Up on successful connection, you'll be prompted to save the secure connection key for future connections to this host. Type YES to save the key or NO to use once. Upon making a choice, you will be prompted for the account password. (Replace "root" with the user name) Once logged in you'll be able to enter the command above to disable or enable the USB Arbitrator setting.

After a fresh install, ESXi will look for a DHCP server from NIC port 1. You can set this manually or

Usually when making a change such as this, you'll have more than one host to action the same change on. We can speed this up a fews ways. From Linux or WSL, you can install "sshpass", this small tool can insert the password in to an SSH session, logging in and allowing you to run just the ESX-CLI commands. To install "sshpass" type the command below. You'll be asked for your password.
