Adventures in WordPress-ing, Oh My!

( Or How Restore your WP Site Manually, no Mirrors!)

The end of October brought a few surprises including a PHP vulnerability and a Kernel flaw.

As of this writing there is no patch for the Kernel issue, however patches for PHP were issued. Since this was a serious vulnerability, I decided to upgrade my WordPress instances.

One of my instances still uses a classic rather than a block theme. Thus I also decided to migrate it.

Well let’s say, I encountered a few issues during this process.

IPv6 Neighbor Discovery (ND) Proxy, Oh My!

In a couple of blogs and I had mentioned ND-PROXY.

OpenNebula, Virtual Routers, VXLan, Oh my!

Hello There.

I did create a lab in which I was able to convert a minione server into a 3 node server, with the initial minione server acting as a controller. Eventually I will write how to do that.

This Blog instead is about the travails of configuring Open Nebula and the limitations of Sunstone the GUI. In particular trying to use VXLans and Virtual Routers.
