- 7. Delphi 11 Copyright © 2022 by Embarcadero, an Idera company Benefits and Use Cases ● Ability to run unmodified ELF64 Linux binaries, expand toolkit and capabilities ● Flexibility of combining Windows and Linux tool chain on one computer ● Less overhead than a traditional virtual machine means better performance ● Local build environment with containers, etc. ● Testing server applications from Windows without additional infrastructure ● No need to mess with dual boot or 3rd party VM installation ● Invoke Linux binaries from Windows and Windows executables from Linux ● Runs as you need it, less management ● Memory and drive space are dynamically shared

- 9. Delphi 11 Copyright © 2022 by Embarcadero, an Idera company Available Distributions ● Ubuntu, Kali, & Pengwin are in the Debian family (using .deb pkgs - apt) ○ Kali is focused on security ○ Pengwin is designed around WSL ● SUSE and Fedora are in the RPM family with Red Hat ● Alpine is an independent, lightweight, security-oriented, Linux distribution ● Some distros include multiple versions
- 10. Delphi 11 Copyright © 2022 by Embarcadero, an Idera company Managing WSL Distros ● List distributions ○ wsl --list --all or wsl --list --running ● Set default distribution ○ wsl --setdefault <DistributionName> or wsl -s <DistributionName> ● Run a specific distro ○ wsl --distribution <DistributionName> ● Run as specified user ○ wsl --user <Username> (or use the specific distro name) ● Unregister and uninstall a distribution ○ wsl --unregister <DistributionName> ● Shutdown all WSL instances ○ wsl --shutdown
- 11. Delphi 11 Copyright © 2022 by Embarcadero, an Idera company First Run ▪ On first run you are usually prompted for a username and password ▪ openSUSE uses YaST2 for a nice ASCII GUI
- 12. Delphi 11 Copyright © 2022 by Embarcadero, an Idera company Connecting from the IDE ● Tools -> Options -> Deployment -> Connection Profile Manager ● The IP address and ports are shared with the host ● So you connect to 127.0.0.1 ● Can only use each port number once (even if you have multiple distros setup) ● So use different port numbers for multiple instances if you want to run them simultaneously
- 13. Delphi 11 Copyright © 2022 by Embarcadero, an Idera company Linux User Password Reset 1. Note your username 2. From Windows terminal get the distro name ➢ wsl -l 3. From Windows terminal switch default-user to root ➢ ubuntu config --default-user root 4. Launch the WSL distro (you will be logged in as root) ➢ ubuntu 5. Change the user’s password ➢ passwd username 6. Change the default user back ➢ ubuntu config --default-user username 7. Launch the WSL distro again
- 14. Delphi 11 Copyright © 2022 by Embarcadero, an Idera company Accessing Files Between Systems ● Access Windows from Linux ○ cd /mnt/c/ ● Open WSL in current Windows directory ○ wsl ○ wsl -d ubuntu ○ ubuntu ● Access Linux from Windows ○ wsl.localhost ● Open current Linux path from Windows ○ explorer.exe . ○ cmd.exe ○ powershell.exe
