uftpserver

I wanted a simple way of remotely managing files on my ESP8266 so I experimented with this minimal FTP server enough to get file listing, retrieving, and uploading working.

It's a functioning prototype now with a lot of room for improvement but it seems to work fine with the standard mac FTP client and ftp:// access via Chrome.

Check out an alternative FTP server that expanded quite a bit on this prototype here.

Limitations

• Passive mode only
• A single data connection at a time
• Data transfer is assumed to be in binary mode (ascii setting is ignored)
• Operation blocks the thread
• No authentication support

What is supported

• Changing directories (cd/CWD)
• Directory listing (ls/LIST with no parameters)
• File retrievals (get/RETR)
• File uploads (put/STOR)

Future Work

Here are some items I have in mind:

• non-blocking/callback based so it can run in the background with other scripts
• refactor the code for encapsulation purposes and to reduce memory use
• support for more commands and bit more robustness with the current ones
