    Issues with FTP server and client features

    Hi there,

    I am surprised as I cant use FTP to connect to/from foobar2000 mobile app (beta 1.1.10 on Android 7.0 Galaxy A3 2017).

    * From foobar2000 mobile app to my NAS
    I entered the address as ftp://userassword@hostort, but I get following error:
    cannot be accessed, reason:
    FTP: 503, bad sequence of command

    However, using another FTP client app (ES explorer), everything works fine.

    * From my Linux PC (Debian 9.4 amd64) to foobar200 mobile (FTP server on):
    If run from a terminal:
    $ ftp IP_ADDRESS:PORT
    I get:
    ftp: IP_ADDRESS:PORT: Name or service not known
    ftp>

    Are there still some bugs with FTP server/client in Android version?
    Does anybody succeed with such tasks?

    Thank you

    Ynn

    Some clarifications about my post (because of unexpected emojis) :
    * From foobar2000 mobile app to my NAS
    I entered the address as
    Code:
    ftp://user:password@host:port/
    but I get following error:
    Code:
    cannot be accessed, reason:
    FTP: 503, bad sequence of command

    Thanks for the bug report. What exact NAS model is this and what FTP software is it running? Do you know of a public server that I can test this against?


    As for connecting from Linux ftp command, it does not take address in IP_ADDRESS:PORT format, the syntax (according to man ftp) is:
    ftp -46pinegvd [host [port]]
    So the command will typically look like:
    ftp 192.168.0.NN 2100

    ( We don't use the standard FTP port 21 as Android system doesn't let us, as far as I know )

    Thanks for your answer.

    I could finally get access to the FTP server running by foobar2000 mobile on my Smartphone. Using the proper command helped! Problem fixed.

    About the access to my NAS, it is the one provided by my french Internet Access Provider (Free). It is integrated in the modem. The model is Freebox Server (v6) and here is an incomplete list of the softwares (opensource) with patches running on it: https://floss.freebox.fr/freebox_ser...2.0/index.html. I could make some screenshots of the full list of software
    list1.jpg
    list2.jpg
    list3.jpg
    I could not manage to find which one is used for FTP.

    I can configure a temporary password to let you make some tests, but with distant access it is ftpes address/protocol (which is not supported in foobar2000 mobile I guess).
    Should I send you the FTP address, login and password by PM ?

    About the NAS-
    If you connect to it using Linux "ftp" command, what lines does it print before asking for login? It should report exact FTP server software and version there.
    Example from my own NAS:
    Code:
    [~] * ftp localhost
    Connected to localhost.
    220 NASFTPD Turbo station 1.3.5a Server (ProFTPD)

    Here is what is printed once I am connecting to the NAS, it does not provide much...
    Code:
    $ ftp -nv mafreebox.freebox.fr
    Connected to mafreebox.freebox.fr.
    220 Welcome to Freebox FTP Server.
    ftp>
    I will try to find more info about the hardware and software.
