For most users, the message headers of any given email are irrelevant; the email has arrived, and that is all there is to say about that. It does, however, have applications both in IT support and in information security. While those applications are outside the scope of this article, accessing the message header is not.
Thoughts on many things Posts
Last week’s post was my review of the reMarkable. As I noted, though a very good device, it is not perfect. Specifically, there are a few things I would like to see change on the hardware level:
Despite being very much a citizen of the digital world, I am a long-time lover of hand-written notes. I read and annotate reports, and prefer doing so with pen in hand. As such, I suppose it was inevitable that I would find and try out the reMarkable. Their ad blurb says:
With surprising regularity, I need to check when a user last logged in. I recently found a command that returns this information;
quser. Using it is simple enough; open a command prompt, enter the command, and hit return:
I have been a fan of Star Trek since I first saw “Encounter at Farpoint” something like thirty years ago. The combination of curiosity, science fiction, and a society to which I believe we would do well to aspire genuinely makes me happy. Although I wouldn’t claim that all of Trek is good (but rather that there is a fair amount of schlock in Trek), I enjoy it a lot.
Depending on how things are being run, you may need to change the UPN (User Principal Name) of individual users in your Active Directory. One reason for doing so is to use a hybrid local/Azure AD setup, where users use their email address for logging on to Azure, but their ordinary username to log on to the local domain. At any rate, here’s how to change the UPN of an individual user in Microsoft Active Directory:
I believe very strongly in the power of documentation, for a number of reasons. Knowledge should be kept in an ordered manner, and writing documentation is a good way of not only ordering the knowledge, but double-checking it. In addition, by placing the documentation somewhere accessible, you can share it.
Whenever I get a new (Windows) computer, one of the very first pieces of software I download and install is Notepad++. It gets used for just about anything, and everything, and takes the concept of Notepad, a simple text editor, up a few hundred notches.
Last week, I showed you how I find all the nested members of a specified group. When we get requests for such audits, however, they usually specify doing so for a number of groups. Now, we could of course do it, one group at a time, adding information to the
Some time ago, I was asked to provide a list of everyone with access to a specific system. After communicating with the client, it transpired that they were particularly interested in knowing who were the members of a set of Active Directory groups. While this can be done manually, I wanted to try my hand at building a PowerShell-script that returned the information the client was asking for, and which I could reuse at some later point, as such requests pop up with some regularity.
Some software comes and goes, and other software is there for you for the long term. Spacemonger is one of the latter category. Simply put, it scans a hard drive and shows you what’s on it using blocks to represent relative file/folder size, like so:
