Unreliable Operation: FTP, Telnet, Power, ...

[mhepp]

Yes, i also found that when the FTP client does not observe the constraints (e.g. trying TLS or opening a second connection), the whole system seems to freeze. I tested this by running a loop in a Telnet window, which suddenly stopped when the FTP client opened a second connection.

Yes I am aware that other clients can make it crash. I'll work on that soon.

I found out how to see what commands are being sent by lftp, and it looks like this:

Code: Select all

---- Connecting to 192.168.0.17 (192.168.0.17) port 21
<--- 220 Micropython FTP Server
---> FEAT
<--- 332                         
---> AUTH TLS
<--- 332                        
---> USER micro

At this pooint WiPy probably crashes, as it becomes unresponsive and the heartbeat LED stops blinking. I can totally understand that TLS is not supported, but I'm quite sure it shouldn't cause the board to crash.

UPDATE: "set ftp:ssl-allow no" makes it work just fine, so that must be it.

Thanks deshipu!

I agree! I need to investigate why it crashes when a secure connection is attempted.

I think what will help future users to avoid my problems is adding a one-page instruction sheet to the box that

Thanks, that's a good idea.

Hi all,

The crash issues when a secured or multiple FTP connections are attempted should be fixed now. Damien has setup a daily build of the WiPy here: http://micropython.org/download/ , feel free to test it and let us know if the FTP problems are gone. Thanks!

Cheers,
Daniel

What's that about? Any idea what are the errors that lftp refers to?
