ftp-go

An FTP server implementation in Go.

Forked from https://gitea.com/goftp/server (Contributors).

Installation

go get github.com/globalcyberalliance/ftp-go

Usage

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

Look at the file driver to see an example of how to build a backend.

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

host: 127.0.0.1
port: 2121
username: admin
password: 123456

This uses the file driver mentioned above to serve files.

Warning

FTP is an incredibly insecure protocol. Avoid forcing users to authenticate with important credentials.

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.
