ESXi doesn’t have a Service Console like ESX. Therefore, you can’t SSH to the server without entering unsupported mode. That process may be a hassle if all you need to do is modify VM configuration files. Of ourse, you could use the Datastore Browser from the VI/vSphere Client, but to make file edits you would have to download a file to your desktop, edit it, and then upload the changed version back to ESXi again. On the other hand, with Veeam’s free FastSCP editing files on ESXi datastores is easy.
To be clear, you can’t edit configuration files of the ESXi host itself with FastSCP, but there really should not be a need to do so. That’s one of the benefits of ESXi not having a Service Console!
Download FastSCP here. You will have to register with Veeam first, and the registration form will not accept a personal email. I’m guessing there is some kind of lead qualification strategy and support registration involved with this requirement for download, but I learned a work address is unavoidable. I tried to use my gmail address but received a message similar to “you must use a company email address.” The registration process ends with a confirmation email to be acknowledged before you can download, so making up a fake email is futile. Hey, it’s a small price to pay for a free, quality admin tool.
After you install FastSCP you’ll discover you have access to a trial period of Veeam Backup and Replication. I suggest exploring
