Passwd Service

This repository contains an example project consisting of a simple, cross-platform REST API developed using ASP.NET Core.

Getting Started on Linux and macOS

Download and run the .NET Core SDK installer for your platform. A version 2.2.105 or higher release of the .NET Core SDK is required. The latest available version is recommended. (For reference, the minimum version of the .NET Core SDK required may be found by inspecting the sdk property in the global.json file.)

To clone the example project repository to your home folder, run the following commands:

cd ~
git clone https://github.com/seniorquico/PasswdService.git PasswdService

To build the example project, run the following commands:

cd ~/PasswdService
dotnet publish ./src/PasswdService/PasswdService.csproj --configuration Release --output ~/PasswdService/app/

To configure the example project, open the ~/PasswdService/app/appsettings.json file in your favorite text editor. Adjust the GroupFilePath and GroupFileName settings to point to a valid /etc/group file. Adjust the PasswordFilePath and PasswordFileName settings to point to a valid /etc/group file. For example, your configuration may end up looking similar to the following:

{
  "AllowedHosts": "*",
  "Logging": {
    "LogLevel": {
      "Default": "Warning"
    }
  },
  "PasswdService": {
    "GroupFileName": "group",
    "GroupFilePath": "/etc",
    "PasswordFileName": "passwd",
    "PasswordFilePath": "/etc"
  }
}

The folder(s) identified by GroupFilePath and PasswordFilePath must exist before running the example project.

Depending on your system's security settings, the example project may not be able to access the actual /etc/group and /etc/passwd files when running (for good reason). If this is true for your system, simply copy /etc/group and /etc/passwd to a different folder, remove any sensitive information from the copied files, and update the GroupFilePath and PasswordFilePath settings accordingly.

To run the example project, run the following commands:

cd ~/PasswdService/app
dotnet PasswdService.dll

Congratulations, you're now running the Passwd Service! You may exercise the REST API using your favorite HTTP client with the following base URL:

http://localhost:5000/

Alternatively, you may explore and test the REST API using the bundled Swagger UI utility:

http://localhost:5000/swagger/

Getting Started on Windows

Download and run the .NET Core SDK installer for 64-bit Windows (this example project is not supported on 32-bit Windows). A version 2.2.105 or higher release of .NET Core SDK is required. The latest available version is recommended. (For reference, the minimum version of the .NET Core SDK required may be found by inspecting the sdk property in the global.json file.)

To clone the example project repository to your user profile folder, run the following commands:

cd "%USERPROFILE%"
git clone https://github.com/seniorquico/PasswdService.git PasswdService

To build the example project, run the following commands:

cd "%USERPROFILE%\PasswdService"
dotnet publish .\src\PasswdService\PasswdService.csproj --configuration Release --output "%USERPROFILE%\PasswdService\app"

To configure the example project, open the %USERPROFILE%\PasswdService\app\appsettings.json file in your favorite text editor. Adjust the GroupFilePath and GroupFileName settings to point to a valid /etc/group file. Adjust the PasswordFilePath and PasswordFileName settings to point to a valid /etc/group file. Be sure to escape any backslashes in the GroupFilePath and PasswordFilePath values. For example, your configuration may end up looking similar to the following:

{
  "AllowedHosts": "*",
  "Logging": {
    "LogLevel": {
      "Default": "Warning"
    }
  },
  "PasswdService": {
    "GroupFileName": "group",
    "GroupFilePath": "C:\\Example Configuration",
    "PasswordFileName": "passwd",
    "PasswordFilePath": "C:\\Example Configuration"
  }
}

The folder(s) identified by GroupFilePath and PasswordFilePath must exist before running the example project.

To run the example project, run the following commands:

cd "%USERPROFILE%\PasswdService\app"
dotnet PasswdService.dll

Congratulations, you're now running the Passwd Service! You may exercise the REST API using your favorite HTTP client with the following base URL:
