fineFTP Server

FineFTP is a minimal FTP server library for Windows and Unix flavors. The project is CMake based and only depends on asio, which is integrated as git submodule. No boost is required.

You can easily embed this library into your own project in order to create an embedded FTP Server. It was developed and tested on Windows 10 (Visual Studio 2015 / 2019, MinGW) and Ubuntu 16.04 - 21.10 (gcc 5.4.0 - 11.2.0).

Features

FTP Passive mode (the only mode you need nowadays)
Listing directories
Uploading and downloading files
Creating and removing files and directories
User authentication (and anonymous user without authentication)
Individual local home path for each user
Access control on a per-user-basis
UTF8 support (On Windows MSVC only)

fineFTP does not support any kind of encryption. You should only use fineFTP in trusted networks.

Example

Using fineFTP in your application is simple. Just create an FtpServer object, add one or multiple users and start the server.

#include <fineftp/server.h>
#include <thread>
 
int main() {
  // Create an FTP Server on port 2121. We use 2121 instead of the default port
  // 21, as your application would need root privileges to open port 21.
  fineftp::FtpServer ftp_server(2121);
 
  // Add the well known anonymous user. Clients can log in using username
  // "anonymous" or "ftp" with any password. The user will be able to access
  // your C:\ drive and upload, download, create or delete files. On Linux just
  // replace "C:\\" with any valid path. FineFTP is designed to be cross-platform.
  ftp_server.addUserAnonymous("C:\\", fineftp::Permission::All);
  
  // Start the FTP Server with a thread-pool size of 4.
  ftp_server.start(4);
 
  // Prevent the application from exiting immediately
  for (;;) std::this_thread::sleep_for(std::chrono::milliseconds(100));
  return 0;
}

How to checkout and build

There is an example project provided that will create an FTP Server at C:\ (Windows) or / (Unix).

Install cmake and git / git-for-windows

Checkout this repo and the asio submodule

git clone https://github.com/eclipse-ecal/fineftp-server.git
cd fineftp-server
git submodule init
git submodule update

CMake the project (Building as debug will add some debug output that is helpful so see if everything is working)
```
mkdir _build
cd _build
cmake .. -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=_install
```
Build the project
- Linux: make
- Windows: Open _build\fineftp.sln with Visual Studio and build the example project
Start fineftp_example / fineftp_example.exe and connect with your favorite FTP Client (e.g. FileZilla) on port 2121 (This port is used so you don't need root privileges to start the FTP server)
