Enable DNS over HTTPS and Encrypted SNI in Firefox

Written by Security

In Firefox 62, Mozilla has added two new features called DNS over HTTPS (DoH) and Trusted Recursive Resolver (TRR). The ideal behind each of these features is to improve user privacy and improved performance. DNS has typically been sent over insecure HTTP allowing anyone on the wire, such as your ISP, to monitor what sites you are visiting.

Below we’ll look at how to enable TRR you can tell Firefox to make DoH it’s first choice and use the system DNS as a fallback option.

The second feature we will be enable is Encrypted SNI, which prevents others from intercepting the TLS SNI extension and use it to determine what websites you are browsing.

Upgrade VCSA 6.5 to VCSA 6.7 Update 1

Written by VMware

VMware vCenter 6.7 U1 has recently been released. Last week I posted how to upgrade VCSA 6.7 to 6.7 Update 1, this post will walk you though upgrading VMware vCenter Server Appliance 6.5 to VCSA 6.7 Update 1!

When doing a VCSA version upgrade the upgrade process is much different, than going from say 6.7 to 6.7 U1. When going from 6.5 to 6.7 the upgrade is actually broken up into two stages.

The first stage involves deploying a brand new vCenter 6.7 appliance. Then the second stage will copy the data from your 6.5 VCSA into the newly deployed 6.7 VCSA from stage 1.
