how to use file manager on android to access ftp-es?

#1 Post by zcfz » 2019-12-13 08:48

I deployed a ftps server (ftp-es) by Filezilla server, which is certificated by itself. Filled the common server name as '192.168.0.102'. The filezilla client access just fine, while the fx file manager or any other file manager in android fail to use it. And I'm sure I checked the 'remember certification' in fx file manager.
Filezilla client access normal.
fx or other file manager can only access regular ftp.

Code: Select all

Not possible, FileZilla Server doesn't support this command. The error is non-fatal and the client continues normally, but...

The FTP clients you are using don't support TLS session resuming. They must be updated to implement this important security feature.

Session resuming can requirement be disabled in the server settings (TLS page), but doing that lowers security. Thus, it's only good as a short-term workaround.

FTP connection problems? Do yourself a favor and read Network Configuration.
All FileZilla products fully support IPv6. http://worldipv6launch.org

Thanks a lot! It can list files now.
But the 'user' settings panel cannot checked to 'force tls for user login' or the list would be empty.
I've mailed them a few days ago, maybe they would notice that.
