Execute a DLL via .xll files and the Excel.Application object's RegisterXLL() method

DLL Execution via Excel.Application RegisterXLL() method

A DLL can be loaded and executed via Excel by initializing the Excel.Application COM object and passing a DLL to the RegisterXLL method. The DLL path does not need to be local, it can also be a UNC path that points to a remote WebDAV server.

When delivering via WebDAV, it should be noted that the DLL is still written to disk but the dropped file is not the one loaded in to the process. This is the case for any file downloaded via WebDAV, and they are stored at: C:\Windows\ServiceProfiles\LocalService\AppData\Local\Temp\TfsStore\Tfs_DAV\.

The RegisterXLL function expects an XLL add-in which is essentially a specially crafted DLL with specific exports. More info on XLL's can be found on MSDN

The XLL can also be executed by double-clicking the .xll file, however there is a security warning. @rxwx has more notes on this here inc

Set up msmtp to send emails emails from Ubuntu/Debian Servers

Setting up email with SMTP on Ubuntu/Debian Servers

I used to sift trough my shell history and bookmarks every time I set up a new testing server in order to be able to send mails. So this should help...

Be aware don't use ssmtp anymore. It's unmaintained and has been removed from Debian and Ubuntu will most definitely follow suit.

Install msmtp

Backup a Raspberry Pi to Proxmox Backup Server using the Proxmox Backup Client

Backup a Raspberry Pi to Proxmox Backup Server using the Proxmox Backup Client

This works on a Pi 4, and should work on a Pi 3, but to work on a Pi Zero you would have to figure out how to compile your own client. More info in this thread on the Proxmox forums.

Determine if your Pi is 32bit or 64bit

Run the following command. If you get arm64, it's 64bit, otherwise you'll see armv7l which is 32bit.

uname -m
