Some DNS providers that support NAPTR records

Sometimes you might want/need to use NAPTR DNS records as part of your SIP setup. A while ago it was quite difficult to find DNS providers that support them and don’t charge you an arm and a leg for it, but the situation has improved quite a bit. Below are some DNS service providers that claimed to support NAPTR records:


About PCI-passthrough’d graphics cards and monitors

Setting up a Windows VM to use a graphics card via PCI-passthrough can yield great performance benefits for the VM. However, one loses the flexibility of easily moving the VM’s video output from one monitor to another; in the past, one could just drag the VM’s VirtualBox window from one screen to another and maybe hit the fullscreen button. Now, the monitor that’s being used by a VM is dictated by the cabling between the graphics card and the monitor(s). How can one now use the same monitor at times for Linux, and at other times for the Windows VM? I will discuss two methods for achieving this, and then finish off with some forward-looking closing notes.

OS switcher

Black plastic project enclosure with a 3-state toggle switch on the side, with 3 positions: Linux, ?, and Win.

My latest hack is for dual-booters: The OS switcher lets you select the operating system (OS) you wish to boot at the flick of a switch, anytime. Booting the OS of your choice no longer requires you to sit in front of your computer, wait for a boot selection screen to show up, and then press some buttons at just the right time.

Installing windows for both native and virtual machine use

My quest to setup a perfect VM to replace my native Windows installation continues…

Previously, I selected appropriate components back when I built my PC. More recently, I managed to setup a VM with GPU and NIC passthrough. Now it was time for the disk: I’d like to to use a dedicated SSD for my Windows installation. The interesting question is, can I install Windows on this dedicated HDD in such a way that I can run it natively as well as a VM? That would allow me to squeeze out the remaining percentages of performance if I absolutely have to.

Moving GPT partitions to another SSD

I started off with one 240GB SSD having both my Windows and Linux partitions, and wanted to upgrade my PC to have 2 SSDs, one with Windows and one with Linux. I run Windows Server 2008r2, which is basically Windows 7 once you’ve set it up appropriately, and Arch Linux. Both are installed as UEFI systems, and thus my SSD has a GPT partition table. I decided I wanted to move the Windows partition, since I’ve found my Windows partitions to run out of space first and the new SSD is bigger than the old one.

Using GnuPG 2.1.x on Windows

I use GPG, specifically GnuPG, on Arch Linux and Windows. Both OSes mount my home directory from my NAS, which contains amongst others my GPG settings and keys. Now, my Arch Linux GnuPG installation got updated from the “stable” 2.0.x series to the “modern” 2.1.x series, which seems to use a new keyring for storing keys. Now, the Windows Gpg4Win installation came with GnuPG 2.0.x, which could no longer find secret keys created under Arch Linux… Continue reading “Using GnuPG 2.1.x on Windows”
