elephantsaunter / server

A FTP server framework written by Golang

server

A FTP server framework forked from github.com/yob/graval and changed a lot.

Full documentation for the package is available on godoc

Version

v0.2.1104

Installation

go get github.com/goftp/server

Usage

To boot an FTP server you will need to provide a driver that speaks to your persistence layer - the required driver contract is listed below.

There is a sample in-memory driver available as a demo. You can build it with this command:

go install github.com/goftp/ftpd

Then run it:

./bin/ftpd

And finally, connect to the server with any FTP client and the following details:

host: 127.0.0.1
port: 2121
username: test
password: 1234

Warning

FTP is an incredibly insecure protocol. Be careful about forcing users to authenticate with a username or password that are important.

Contributing

All suggestions and patches welcome, preferably via a git repository I can pull from. If this library proves useful to you, please let me know.

Further Reading

There are a range of RFCs that together specify the FTP protocol. In chronological order, the more useful ones are:

• http://tools.ietf.org/rfc/rfc959.txt
• http://tools.ietf.org/rfc/rfc1123.txt
• http://tools.ietf.org/rfc/rfc2228.txt
• http://tools.ietf.org/rfc/rfc2389.txt
• http://tools.ietf.org/rfc/rfc2428.txt
• http://tools.ietf.org/rfc/rfc3659.txt
• http://tools.ietf.org/rfc/rfc4217.txt

For an english summary that's somewhat more legible than the RFCs, and provides some commentary on what features are actually useful or relevant 24 years after RFC959 was published:

• http://cr.yp.to/ftp.html

For a history lesson, check out Appendix III of RCF959. It lists the preceding (obsolete) RFC documents that relate to file transfers, including the ye old RFC114 from 1971, "A File Transfer Protocol"

This library is heavily based on em-ftpd, an FTPd framework with similar design goals within the ruby and EventMachine ecosystems. It worked well enough, but you know, callbacks and event loops make me something something.
