ESXi 5.5: How to install an update via SSH Online

In this previous post, I have explained how to install an update to ESXi when you are offline.

Find below the instructions to use when your ESX host is connected to the internet:

Login to ESX via SSH (e.g. with PuTTY)

Run the command to allow the traffic to the Internet

esxcli network firewall ruleset set -e true -r httpClient

Run the command to install the update

esxcli software profile update -d -p ESXi-5.5.0-20140902001-standard

Wait until this completes successfully (this can take a while).

Shut down all guests.

Put host in Maintenance Mode.

Reboot VMWare ESXi
