FTPS implementation is not secure tight

[Sentinel]

FTPS actions require FTP server to have disabled following options:
- Force PROT P to encrypt file transfers when using FTP over TLS
- Require TLS session resumption on data connection when using PROT P
These settings need to be enabled for file transfer to be secure.

When these option on server are enabled (which are as default for filezilla) uploaded files by automagic are empty or actions don't work at all (for example "connection closed by peer" error).

I ever setup Filezilla FTP too and remember got the similar error. But the solution is shortlived, as I quickly found a better way to transfer file to my Windows.

Is FTP (specifically filezilla) a must? Or you are just looking for ways to automating transfer files from Phone to PC? If you don't mind the method, the better solution for me is using native SMB shared folder. Install MiXplorer (from xda) and use the intent broadcast to transfer the file. You can do it vice versa too, starting FTP at your phone. I have show the example here : viewtopic.php?f=4&t=7261 You can find the link to the SMB tutorial too. It takes some setup, but only once. Later you only need to change the destination path only. If you don't mind to configure the FTPS settings, I am sure the Start activity setting is also just another setup for you.

With MiXplorer broadcast actions I don't have the direct ability to check within automagic if the file is successfully overwritten (without redownload and compare or reading the MiXplorer notification in a trigger).

[Desmanto]

Oh, I forgot to state that this is still considered to be a bug and need to be resolved. I just give alternative meanwhile it is being fixed.

MiXplorer doesn't give feedback except the toast message. I thought of catching the notification using trigger notification on screen displayed, and then parse the message from MiXplorer. But most of usage will prompt me error if the files is not sent properly, so I put it aside. Let me check if there is other method we can use to crosscheck the transfer status (success or failed).

Hi,

Did you try to set field Data Channel Protection to Private - P in the configuration of the FTP action? If yes, could you please activate the debug log in the settings of Automagic, execute the action one more time and then send the log by mail to me (menu->Manage->Log, menu->Send Log)

Regards,

I always use the data channel protection "Private - P".

Hi,

Looks like the server closes the connection. Is there anything in the log of the server that indicates the reason for this? Can you please send the log to info@automagic4android.com?

Thanks & Regards,
Martin
