# uftpd: small FTP server for ESP8266, ESP32 and Pyboard D
|
||||
|
||||
**Intro**
|
||||
|
||||
Based on the work of chrisgp - Christopher Popp and pfalcon - Paul Sokolovsky
|
||||
Christopher made a first uftp server script, which runs in foreground.
|
||||
Paul made webrepl with the framework for background operations, which then was used
|
||||
also by Christopher to implement his utelnetsever code.
|
||||
My task was to put all these pieces together and assemble this uftpd.py script,
|
||||
which runs in background and acts as ftp server.
|
||||
Due to its size, for ESP8266 it either has to be integrated into the flash image as frozen
|
||||
bytecode, by placing it into the esp8266/modules folder and performing a rebuild,
|
||||
or it must be compiled into bytecode using mpy-cross and loaded as an .mpy file.
|
||||
The frozen bytecode variant is preferred.
|
||||
|
||||
The server has some limitations:
|
||||
- Binary mode only
|
||||
- Limited multi-session support. The server accepts multiple sessions, but only
|
||||
one session command at a time is served while the other sessions receive a 'busy'
|
||||
response, which still allows interleaved actions.
|
||||
- No user authentication. Any user may log in without a password. User
|
||||
authentication may be added easily, if required.
|
||||
- Not all ftp commands are implemented.
|
||||
- ESP8266 is **NOT** a multitasking platform and the system calls are NOT re-entrant.
|
||||
Even when the ftp server sits in background and can serve requests, **no
|
||||
foreground tasks should run at that time**, especially if they execute system calls.
|
||||
The effects is hardly to predict, although most of the time the device simply
|
||||
crashes.
|
||||
- ESP32 The server is supported from version='v1.9.3-575 on. That is the version
|
||||
which introduced webrepl.
|
||||
|
||||
|
||||
## Start-up
|
||||
|
||||
You'll start the server with:
|
||||
|
||||
`import uftpd`
|
||||
|
||||
The service will immediately be started at port 21 in silent mode. You may
|
||||
stop the service then with:
|
||||
|
||||
`utfpd.stop()`
|
||||
|
||||
When stopped or not started yet, start it manually with:
|
||||
|
||||
`uftpd.start([port = 21][, verbose = level])`
|
||||
or
|
||||
`uftpd.restart([port = 21][, verbose = level])`
|
||||
|
||||
port is the port number (default 21)
|
||||
verbose controls the level of printed activity messages, values 0 .. 2
|
||||
|
||||
You may use
|
||||
`uftd.restart([port = 21][, verbose = level])`
|
||||
as a shortcut for uftp.stop() and uftpd.start().
|
||||
|
||||
## Coverage
|
||||
The server works well with most dedicated ftp clients, and most browsers and file
|
||||
managers. These are test results with an arbitrary selected set:
|
||||
|
||||
**Linux**
|
||||
|
||||
- ftp: works for file & directory operations including support for the m* commands
|
||||
- filezilla, fireftp: work fine, including loading into the editor & saving back.
|
||||
Take care to limit the number of data session to 1.
|
||||
- Nautilus: works mostly, including loading into the editor & saving back.
|
||||
Copying multiple files at once to the esp8266 fails, because nautilus tries
|
||||
to open multiple sessions for that purpose.
|
||||
Configure Nautilus with dconf-editor to show directory count for local dirs only.
|
||||
Once mounted, you can even open a terminal at that spot.
|
||||
The path is something like: /run/user/1000/gvfs/ftp:host=x.y.y.z.
|
||||
- Thunar: works fine, including loading & saving of files.
|
||||
directly into e.g. an editor & saving back.
|
||||
- Dolphin, Konqueror: work fine most of the time, including loading
|
||||
directly into e.g. an editor & saving back. But no obvious disconnect.
|
||||
- Chrome, Firefox: view/navigate directories & and view files
|
||||
|
||||
**Mac OS X, various Versions**
|
||||
|
||||
- ftp: works like on Linux
|
||||
- Chrome, Firefox: view/navigate directories & and view files
|
||||
- FileZilla, FireFtp, Cyberduck: Full operation, once proper configured (see above).
|
||||
Configure Cyberduck to transfer data in the command session.
|
||||
- Finder: Fails. It connects, but then locks in the attempt to display the
|
||||
top level directory repeating attempts to open new sessions. Finder needs
|
||||
full multi-session support, and never closes sessions properly.
|
||||
- Mountainduck: Works well, including proper disconnect when closing.
|
||||
|
||||
|
||||
**Windows 10** (and Windows XP)
|
||||
|
||||
- ftp: supported. Be aware that the Windows variant of ftp differs slightly
|
||||
from the Linux variant, but the most used commands are the same.
|
||||
- File explorer: view/navigate directories & and copy files. For editing files you
|
||||
have to copy them to your PC and back. Windows explorer does not always release the
|
||||
connection when it is closed, which just results in a silent connection, which
|
||||
is closed latest when Windows is shut down.
|
||||
- FileZilla, FireFtp, Cyberduck: Full operation, once proper configured (see above).
|
||||
Configure Cyberduck to transfer data in the command session.
|
||||
- WinSCP: works fine
|
||||
- NppFTP - FTP extension to Notepad++: Works fine and is very convenient.
|
||||
- Mountainduck: Works to some extent, but sometimes stumbles and takes a long
|
||||
time to open a file.
|
||||
|
||||
**Android**
|
||||
|
||||
- ftp inside the terminal emulator termux: full operation.
|
||||
- ftp-express
|
||||
- Chrome: view/navigate directories & and view files
|
||||
|
||||
**IOS 9.1**
|
||||
|
||||
- FTP Client lite: works flawless
|
||||
|
||||
**Windows 10 mobile**
|
||||
|
||||
- Metro file manager: Works with file/directory view & navigate, file download,
|
||||
file upload, file delete, file rename. Slow and chaotic sequence of FTP commands.
|
||||
Many unneeded re-login attempts.
|
||||
|
||||
**Conclusion**: All dedicated ftp clients work fine, and most
|
||||
of the file managers too.
|
||||
|
||||
## Trouble shooting
|
||||
The only trouble observed so far was clients not releasing the connections. You may tell
|
||||
by the value of `uftp.client_list`, which should be empty if no client is connected, or by issuing the command rstat in ftp, which shows the number of connected clients.
|
||||
In that case you may restart the server with uftpd.restart(). If `uftd.client_busy`
|
||||
is `True` when no client is connected, then restart the server with with
|
||||
`uftpd.restart()`. If you want to see what happens at the server, you may set verbose to 2.
|
||||
Just restart it with `uftpd.restart(verbose = 1)`, or set `uftpd.verbose_l = 1`, and
|
||||
`uftpd.verbose_l = 0` to stop control messages again.
|
||||
|
||||
## Files
|
||||
- uftpd.py: Server source file for ESP8266 and ESP32 from version='v1.9.3-575 on
|
||||
- ftp.py: Simple version of the ftp server, which works in foreground. This
|
||||
can be used with all Micorpython versions. It terminates when the client closes the
|
||||
session. Only a single session is supported by this variant.
