paradise_ftp

paradise_ftp is a powerful, 100% native (golang) ftp server that is production ready.

It can handle 1000's of connections and 1000's of files flying back and forward sideways under and through. It does not run out of file descriptors. It does not forget to close any socket connection or socket listener. Ahem hem, cough cough, looking at you https://github.com/goftp/server.

FYI FTP is a big protocol and I only implemented the stuff I needed. Stuff that's here:

Sample Run:

$ ftp ftp://auser:secret@127.0.0.1:2121
