Vs-wsl-fortranA Fortran example project using Visual Studio and Windows Subsystem for Linux (WSL).Getting startedRequirementsVisual Studio 2019Windows Subsystem for Linux (WSL)Note: This was tested on a system with Windows 10 2004, Visual Studio 16.6 and WSL 2.Prepare the WSLDownload and install a Linux distribution for WSL.This example was tested with Debian Buster, but other distributions should work just as well.Install the packages needed for your WSL installation to work with Visual Studio:sudo apt install g++ gdb make ninja-build rsync zipFor more detailed instructions see theLinux development with C++ documentation.In addition we need to install the gfortran compiler:sudo apt install gfortranBuild the projectStart Visual Studio and open the vs-wsl-fortran folder.Select the WSL-GCC-Debug target, then build it.Run the Linux executable inside Visual StudioSelect vs-wsl-fortran (src\vs-wsl-fortran) as the startup item and start it (F5).To see the output you might need to open the Linux Console Window view.Cross-compile a Windows executableThe mingw compiler can be used to create Windows binaries.Install an appropriate mingw package in the WSL installation, for example:sudo aptitude install gfortran-mingw-w64-x86-64Build the project for WindowsIn Visual Studio select the WSL-MINGW-Release target and build it.After building the executable you still need to copy some DLLs into that folder.In the case of Debian these DLLs are provided by the mingw package:/out/build/WSL-MINGW-Release/srccp /usr/lib/gcc/x86_64-w64-mingw32/8.3-win32/*.dll .">cd vs-wsl-fortran_folder>/out/build/WSL-MINGW-Release/srccp /usr/lib/gcc/x86_64-w64-mingw32/8.3-win32/*.dll .Now you can run the executable in a Windows PowerShell or CMD:NotesCMakeSettings.jsonNinja is not yet supported for Fortran, so generator has to be set to "Unix Makefiles" instead.When cross compiling the compiler has to be specified with "-DCMAKE_Fortran_COMPILER=/usr/bin/x86_64-w64-mingw32-gfortran" in the CMake Command Arguments.This is not necessary when targeting Linux, in that case the default gfortran compiler is detected automatically.Fortran syntax highlighting in Visual StudioBy default Visual Studio does not provide any syntax highlighting for Fortran code,but it can be added as described here.First create the following folder:%userprofile%\.vs\Extensions\Syntaxes\Then download an appropriate

WSL 2 and Cisco AnyConnect VPN: A Networking SolutionIntroductionThis repository provides a workaround for a known issue with WSL 2 and Cisco AnyConnect VPN. When a VPN session is established, firewall rules and routes are added that disrupt network connectivity within the WSL 2 VM. This issue is tracked in WSL/issues/4277 and WSL/issues/5068.The provided scripts automatically configure the interface metric on VPN connect and update DNS settings (/etc/resolv.conf) on connect/disconnect, thereby maintaining network connectivity.Getting StartedPrerequisitesEnsure that you have WSL 2 and Cisco AnyConnect VPN installed on your system.InstallationClone this repository or download the scripts.Save the scripts to a local directory, for example, %HOMEPATH%\wsl\scripts.Scripts descriptionsetCiscoVpnMetric.ps1This PowerShell script adjusts the network interface metric for the Cisco AnyConnect VPN adapter to prevent the VPN connection from interfering with other network connections in WSL 2.When executed, the script:Retrieves all network adapters on the system using the Get-NetAdapter cmdlet.Filters these adapters to find the one with an interface description that matches "Cisco AnyConnect" using the Where-Object cmdlet.Sets the interface metric of the Cisco AnyConnect adapter to 6000 using the Set-NetIPInterface cmdlet.This high interface metric ensures that the system prioritizes other network interfaces over the VPN when establishing network connections.setDns.ps1The setDns.ps1 script is a PowerShell script designed to update the DNS settings in a WSL 2 Linux VM. This is particularly useful in environments where the VPN connection might interfere with other network connections, such as with WSL 2.When run, the script performs the following steps:It uses the Get-NetAdapter cmdlet to retrieve all network adapters on the system.It filters these adapters with the Where-Object cmdlet to find the adapter with an interface description that matches "Cisco AnyConnect".It then uses the Set-NetIPInterface cmdlet to set the interface metric of the Cisco AnyConnect adapter to 6000.By setting a high interface metric, the system will prioritize other network interfaces over the VPN when establishing network connections. This can help to maintain network connectivity in certain situations where the VPN might otherwise take precedence.UsageWSL configuration (one time setup)Open WSL 2Run the following command to unlink the default /etc/resolv.conf file in WSL 2 and prevent it from being overwritten on startup:sudo
