Per-directory case sensitivity and WSL

If you have used the Windows Subsystem for Linux, you’re probably aware that it allows you to treat your Windows file systems (mounted under /mnt/c, /mnt/d, etc.) as case sensitive. This means, among other things, that you can create files whose names differ only by case (e.g. foo.txt and FOO.TXT). However, using those files in Windows was ...

Windows/WSL Interop with AF_UNIX

Starting in Windows Insider build 17093, a WSL application can communicate with a Windows application over Unix sockets. Back in December, we blogged about bringing AF_UNIX to Windows. Now, we're building on that functionality. Consider a requirement where you want to run some kind of service as a Windows application. Additionally, you would ...

OpenSSH in Windows 10!

SSH is one of the most important tools in the *NIX world, through which users communicate with shells, applications, and services running on remote machines, devices, VM's and containers.

AF_UNIX comes to Windows

Introduction:  Beginning in Insider Build 17063, you’ll be able to use the unix socket (AF_UNIX) address family on Windows to communicate between Win32 processes. Unix sockets allow inter-process communication (IPC) between processes on the same machine.  Overview:  Support for the unix socket has existed both in BSD and Linux for the ...

[Cross Post] WSL Interoperability with Docker

We frequently get asked about running docker from within the Windows Subsystem for Linux (WSL). We don’t support running the docker daemon directly in WSL. But what you can do is call in to the daemon running under Windows from WSL. What does this let you do? You can create dockerfiles, build them, and run them in the daemon—Windows or ...

Background Task Support in WSL

Starting in Windows Insiders Build 17046, WSL supports background tasks (including daemons). In the past, if you opened WSL and started sshd, httpd, screen, or tmux  you needed to have a console window open to keep those tools running. But, starting with 17046, these processes will continue running in the background even after the last ...
