HTTP file sharing server

This is a file sharing server that runs on HTTP. It will list the files and directories in it's working directory, and the client can choose to download a specific file. Currently, only HTTP GET method is supported. As of now, every connection will be closed once the request has been served (no persistent connections)

Features

• Configurable working directory (using -d option)
• Concurrent connections (using a thread pool of configurable size: -t option)
• Zero copy file send (using sendfile)

Building

use GNU make

make

Portability

This code is mostly portable. As of now, the platform specific functionalities are:

• poll ()
• MSG_NOSIGNAL flag for send ()
• Unix sockets (not supported on windows)
• sendfile ()

Issues

This server is not very secure, and I'm not talking about the fact that it's not running on HTTPS. This server is prone to simple Denial-of-Service attacks. Please ensure that you don't run this as root. If you do need to bind it to port 80, you can set the capabilities of the server using

sudo setcap cap_net_bind_service=ep <path-to-binary>
