Configure Fileserver with the Phone

[geronimo123]

Hello on the Forum

I was trying to setup my Fillezilla Server with the Phone. Basically, I wanted to configure phone to manually synchronize files from Keepass2android and with my computer.
So, I've setup server, estabilished connectivity with it, but apperently I couldn't really connect the app with my server.

I don't reallly understand how can I do it.
My phone is connecting thru Wi-Fi. My computer is over cable. Both in the same private network.

When I try to add IP of my phone I got a erorr: Couldn't bind on "my phone IP address":21. Reason: WSAEADDRNOTAVAIL. - Cannot assign requested address.

When I try to connect to the server on my application thru FTP - I type my creds (I've created user before with password) - but when I try to connect (server is seeing my phone) but I got erorr: 503 Use AUTH first.
I've put down my firewall so I don't really understand what I am doing wrong.

Any help in that matter? I've try to search over the internet, but without success.

The server's listeners can only be bound to interfaces local to the server machine.

Make sure to use a modern FTP client that speaks FTP over TLS.

Hey, thanks for the reply!

- Well, phone is connecting to my home router, so basically isn't that makes it local? Same network as computer (so basically server I've created)

Make sure to use a modern FTP client that speaks FTP over TLS.

There is an option, you can create a rule that states: Explicit FTP over TLS and insecure plain FTP
So, basically Keepass2Android is connecting with insecure plain FTP. My phone also (that why I can connect to the browser ftp:\\ ??
Maybe I'm missing something...

There are different types of local. Local to the machine and local to the network are quite different.

Not uncommon for many telephone apps to have sub-par, if at all, security.

So, basically you are telling, there is no way this connection could work?
I mean FileZilla Server to the Application? Even thru server is connecting to the application?

You have it backwards. Servers listen on a network interface local to the machine for connections coming from other machines.

Okay, I actually understand, that application is connecting to the server, but I am not sure why this connection is failling...

EDIT: You said "coming from other machines" so the phone could be treat as such.

You seem to require FTP over TLS on your server. The FTP client on the phone tries to log in unencrypted. Thus the server tells the client there is no way of logging in without sending AUTH TLS or AUTH SSL, to enable FTP over TLS Explicit communication.
