One of most difficult things to find (imho) is information about API and Service URL’s for just about any and all applications. Microsoft is better than some (Dell, I am looking at you…) but it can still require some metaphorical google search back flips to get to the right information.
That said… I wanted to quickly document the right mix of URL’s that must be allowed in order for Windows OS license activation to work: (more…)
The Event Viewer is a very useful tool however, like any log management solution, the biggest hurdle can be filtering out the noise and returning only the meaningful log data that you care about.
This is a follow-up on a previous article which can be viewed here: Finding Human Logins in the Windows Event Viewer – Suppressing Everything Else
One of the most common requests is seeing who has been in and out of a box. To that end, I want to expand a bit more and talk about how to filter on the following three things… Username, Event ID, and Logon Type.

If you are already somewhat comfortable with Proxmox and Debian configuration and just prefer I get to the point then (more…)

The key information I wanted was:
Date and Time of Successful Connections
In my setup, OpenVPN connected users are put into a unique IP subnet and assigned an address by a DHCP server that is part of Access Server. All very easy to setup. In digging through the logs I found entries that are made whenever an IP address is assigned to a newly connected user.
An entry looked something like this: (more…)
