Best FTP settings

Over USB? How did you manage that?

You're right - I thought the FTP was working over the USB but it was actually working over Wifi.
What are the recommended FTP settings to get a smooth connection to the Duet SD card?

The main setting you need is to use only one connection to Port 21 at a time. Some FTP clients default to using a second connection for file uploads, but that won't work with the Duet.

What FTP clients are known to work with the Duet Wifi? I can't get WINSCP to work with the Duet Wifi. I'm running Duet Wifi firmware 1.20 and the latest Widows Device Driver files.

FileZilla

FileZilla is the client that I test with. You need to create an entry in Site Manager for the Duet, and set it to "Max concurrent connections: 1".

Thanks, I loaded FileZilla. As advised above, I created an entry in Site Manager for the Duet, and set it to "Max concurrent connections: 1" and left the transfer mode set to "default". I'm still getting the kinds of errors as below.

What are the settings under the FileZilla general tab that I should be using? Port, protocol, encryption, logon type? And how do I define the FTP "user" name for the logon….do I need to add it into the Duet config.g file or do I just re-use the host name as the FTP user name or do I just leave it blank?

Is there a Duet wiki that I am missing that covers all this?

Sorry - the last log had a password error which I fixed. This one lists the main SD directory but bangs out when I try to see inside /www/css. So previous questions in my last post still hold if anyone can please help….

I have FileZilla set for passive, 1 connection, no encryption (plain), server type is Default (autodetect), character set is autodetect.

I've not yet been able to successfully transfer a file to or from either of my Duets.

Try firmware 1.21RC3 which includes a fix for some similar FTP issues.

Marc Lee · 9 Mar 2018, 05:13

Thanks for the FileZilla config info Richard…and for confirming that it is probably a bug (and not just me going crazy!) I think I might just have to wait for the 1.21 release launch - when is that likely to be David?
