ftp

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

Full documentation for the package is available on godoc

Installation

go get gortc.io/ftp

Changes from goftp

1. Handle ABOR command
2. Extend drivers
   • Notify about ABOR via Abort()
   • Call Close on FTP connection termination
   • Add offset to PutFile
3. Fix STOR error code from 450 to 550
4. Fix data race in Shutdown

Warning

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

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.
