Building the WSL2 kernel with Clang
by Simon Eigeldinger 01 Nov '20

01 Nov '20

Some nerds might be interested: Building the WSL2 kernel with Clang Last updated: 22:10 30.10.2020 Or just get it and this documentation from here: https://www.dropbox.com/sh/nhcbxnv5zllxuof/AABbHdkf3Yd4RuEPnkBf5MMLa?dl=0 Sources https://nathanchance.dev/posts/wsl2-kernel-clang/ https://www.xyb.name/2020/03/14/build-your-kernel-for-wsl2/ Howto 1. Download and install the needed tools. Use Ubuntu 20.04. Ubuntu 20.10 seems not to work at the moment. $ sudo apt update $ sudo apt upgrade $ sudo apt install -y --no-install-recommends bc bison build-essential ca-certificates flex git gnupg libelf-dev libssl-dev lsb-release software-properties-common wget Install Clang 11 $ cd ~ $ wget https://apt.llvm.org/llvm.sh $ chmod +x llvm.sh $ sudo ./llvm.sh 11 2. Download the kernel source code The latest is 5.9.2 at the moment. $ wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.9.2.tar.xz $ tar xf linux-5.9.2.tar.xz $ cd linux-5.9.2 $ wget https://raw.githubusercontent.com/microsoft/WSL2-Linux-Kernel/master/Micros… 3. Build the kernel. An out directory (out.x86_64) can be handy to have a clean environment. $ make -j$(nproc) -s CC=clang-11 KCONFIG_CONFIG=config-wsl LD=ld.lld-11 O=out.x86_64 distclean olddefconfig all 1. Move the kernel to the Windows file system. I have my kernels sitting at e:\wsl\kernel. $ cp out.x86_64/arch/x86/boot/bzImage /mnt/e/wsl/kernel/linux-5.9.2 2. Tell WSL2 to use that kernel when booting up. Create a .wslconfig file in your user directory for example at c:\users\username. This file should contain the following: [wsl2] kernel = e:\\wsl\\kernel\\linux-5.9.2 Note that you need to use double backslashes. Then do on a cmd window. $ wsl --shutdown Then load a linux distro and type $ cat /proc/version Now you should see something like that Linux version 5.9.2-microsoft-standard (root@SimonPC) (Ubuntu clang version 11.0.0-++20201021094914+176249bd673-1~exp1~2 0201021075533.113, LLD 11.0.0) #1 SMP Fri Oct 30 21:04:46 CET 2020 Some have noticed that the VM gets stuck starting with a custom kernel at times; if that happens, run wsl --shutdown and try reopening one of the distributions again, it will usually work after a couple of times. Enjoy.

hyper v
by Marvin Hunkin 30 Oct '20

30 Oct '20

Hi. Okay will go and research that. And do have jaws running, unless need the remote jaws and then either need to get a trial licence or need to then purchase. With nvda, does this process work. When I launched nvda, it was able to read the configuration dialog and the preferences. But jaws did not. Okay will see if there's an article how to forward all keystrokes to hyper vi via nvda key strokes. Thanks. Ps: my friend install virtual box, but kept crashing and powering off. My 30 day vm ware workstation trial ended, and did not want to use crack keys. And when I did research, the vm ware key is stored on the copy or a hidden folder in windows. Thanks.shadow

Hi. A sighted friend is mentoring me for my network course from http://www.upskilled.edu.au. Got windows 10, windows server 2019 and hyper v. is there a way for screen readers to read the content. Jaws , nvda , windows narrator just says input capture. Would window-eyes read this content any better. Thanks.

Evening all, Just wondering if anyone here has experience of SCCM labs. I’m doing the administrateing and configuring SCCM course this week and I’m working through the labs with colleagues. I’m just wondering if there is any value in seeing if work will get me my own platform / machine with enough power to run several VM’s? I’ve seen the Microsoft demo labs, are they any good? grateful for any tips/advice. Thanks, Kieran. Get Outlook for iOS<https://aka.ms/o0ukef> Save Time Do It Online!

Enabling and updating WSL2 and installing a distro on Windows 10 64 Bit
by Simon Eigeldinger 17 Oct '20

17 Oct '20

Enabling and updating WSL2 and installing a distro on Windows 10 64 Bit This is a quick and dirty guide how to enable WSL2 and how to install a distro like Ubuntu. I don't use the Windows Store. This often has older Root FS images and you can't define where to install the disk image later. It just works on Windows 10 64 bit. I heard it also seems to work on ARM64 as well. But then you might need some other instructions. Works on Home, Pro and Enterprise. Enabling and updating WSL1 First we will enable WSL1. This is the old version of WSL and is on by default. So we hit win+r to open the run dialog. then we enter optionalfeatures and hit enter. then we select the checkboxes platform for virtual computers and windows subsystem for linux. then we hit the ok button and the restart button to reboot the computer. Windows then sets up the needed components. After we are in Windows again we download and install the wsl update. That updates the linux kernel for WSL and that it supports WSL2. https://wslstorestorage.blob.core.windows.net/wslblob/wsl_update_x64.msi Enabling WSL2 After we installed above stuff we open a terminal as Administrator. cmd or windows terminal can be used. Then we type wsl --set-default-version 2 to activate WSL2 as default for all new virtual machines. Useful options for the wsl command are for example also: wsl -t distro to terminate and shutdown distributions. wsl --shutdown to shut down the wsl vm server. wsl --help gives much more help to more commands. Downloading and installing Ubuntu 20.04 LTS First let's get WSLDL. This is a 3rd party distro launcher and installer. Latest releases can be found here: https://github.com/yuk7/wsldl/releases/ get the latest launcher.exe. Then we also need a Root filesystem for Ubuntu. This can be found over here: https://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-w… Ubuntu 20.10 can be found here. there are already some daily builds available. though they seem to have not all packages available on apt: https://cloud-images.ubuntu.com/groovy/current/groovy-server-cloudimg-amd64… After that we are going to put all things together. First create a directory on a drive where you have enough space. I created a wsl directory on my e drive because i have a lot of space there. On my computer in the office i created that directory on the c drive. then you create a ubuntu directory in the wsl directory. then you copy the launcher.exe into the ubuntu directory and rename it to ubuntu.exe. So your distro name in wsl will be called ubuntu. you can also rename it to ubuntu-20.04.exe. so your distro name will be ubuntu-20.04. Then rename the .tar.gz file you have downloaded to rootfs.tar.gz and copy it as well into the ubuntu directory. Then execute the exe file as admin. a terminal opens and it says installing... then it displays that you need to hit a key and it installed successfully. you then have a ext4.vhdx file in the directory. This is your disk image. you can delete the rootfs.tar.gz if you want. Though i often keep then so if i want to kill the os i can reinstall it. Starting Ubuntu I often create a desktop icon to the exe and enable start as admin in the compatibility tab of the properties. When hitting enter ubuntu starts. Use your standard terminal navigation keys. Note that you have no window menu with alt+space. Maybe ms will enable that again. Would be much nicer to select the whole terminal buffer. Though you can paste things when enabling ctrl+shift keys in the standard settings of the terminal. using cmd you can do it the following way. open a terminal using cmd. then hit alt+space and select standard values. select the use ctrl+shift+c and ctrl+shift+v for copying and pasting checkbox. then you should be able to paste content with ctrl+shift+v. Accessing files in the Ubuntu disk image You can enter \\wsl$\ubuntu\ in explorer to access all the files of the virtual hard disk. Uninstalling Ubuntu Open up a terminal and enter the ubuntu directory. run ubuntu clean to clean the distro using WSLDL. Backing up Ubuntu To create a backup and to also share your distro with some people you can create a backup. That will be a .tar.gz which someone also can import. Like we did above. Open up a terminal and go into the ubuntu directory. Then execute wsl -t ubuntu to terminate ubuntu Then type ubuntu backup --tgz then a backup.tar.gz will be created which you can share or backup. I hope i haven't forgotten anything.

Installing SageMath on Ubuntu and Arch
by Simon Eigeldinger 16 Oct '20

Installing SageMath on Ubuntu and Arch Another quick and dirty install guide. Installing SageMath on Ubuntu Installing packages with apt update apt upgrade apt install cantor-backend-sage maxima-sage sagetex sagemath sagemath-database-conway-polynomials sagemath-database-elliptic-curves sagemath-database-graphs sagemath-database-mutually-combinatorial-designs sagemath-database-polytopes sagemath-doc sagemath-jupyter screen Then set the jupyter password with the command jupyter notebook password Then you are asked for a password. After that we create a notebooks dir and cd into it. then we start the jupyter server. mkdir notebooks cd notebooks jupyter notebook --allow-root When closing the terminal window you will have no server. You can hold it open with screen. The notebook will be available on http://localhost:8888/ with set password. Installing SageMath on Arch The same as above though with the following install commands. pacman -Syu pacman -S sage-data-elliptic_curves sage-numerical-backends-coin sagemath sagemath-doc sagemath-jupyter sagetex screen
