FTP über SSL

  • Hallo NetCup Forum Users,


    Ich bin Programmierer in Delphi und möchte einen FTP Zugriff über mein Programm erhalten. Dort gibt es eine FTP Komponente, diese Besitz aber lediglich nur FTP over SSL.
    Derzeit gibt es leider keine anderen Alternativen zu dieser Komponente. Daher muss ich wohl oder übel meinen FTP Server umstellen auf SSL. Dies habe ich bereits getestet. Bin aber dann beim Einloggen gescheitert (Tests mit FileZilla durchgeführt). Bzw. der Client loggte sich ein (als root) und erhielt sofort nach dem Einloggen "Permission denied". Dies habe ich auch mehrfach gegoogled, aber ohne Erfolg. Das einzige auf was ich gestoßen bin, ist "SELinux", dass man dort etwas einstellen sollte. Daraufhin habe ich nachgeschaut ob SELinux installiert ist. Dies bestätigte sich daraufhin. Nur leider war es deaktiviert/disabled.
    Meine Frage: Kann jemand von Ihnen mir helfen, den FTP mit Erfolg umzustellen?


    MFG,
    im Voraus Fabian L.


    Edit: Besitze den KVM-VServer Jupiter

  • Du sagst du willst FTP über SSL.


    Du nutzt FTP über SSH.


    Das ist nicht das gleiche (ftps != sftp) und da ist der Fehler.


    Je nachdem was du wirklich willst musst du es entsprechend einrichten bzw. wirst du mit dem Wissen besser Googlen können.

  • Falsch, SFTP ist der FTP-Zugriff über SSH und kein anderes Protokoll! ;)


    SSH File Transfer Protocol – Wikipedia


    Und bei Wikipedia steht allerdings "Alternative" und es werden sogar Unterschiede genannt...
    Im englischen Wikipedia-Artikel wird es deutlicher:

    Zitat

    SFTP is not FTP run over SSH, but rather a new protocol designed from the ground up by the IETF SECSH working group.

  • Back to topic: Nutz ein ftpd und konfiguriere den nach deinen wünschen

    Genau, habe ich ja bereits gemacht, aber nachdem ich es konfiguriert habe und ich mich eingeloggt habe mit ssl (FileZilla port 21), stand dort "Permission denied" nach dem "Successfull logged in".
    Ich denke ich habe dort was falsch gemacht oder was übersehen, ich poste einfach mal die vsftp.conf. Vielleicht hilft es ja ;)



    Und Vielen Dank für die schnellen Antworten! :)

  • # Example config file /etc/vsftpd.conf
    #
    # The default compiled in settings are fairly paranoid. This sample file
    # loosens things up a bit, to make the ftp daemon more usable.
    # Please see vsftpd.conf.5 for all compiled in defaults.
    #
    # READ THIS: This example file is NOT an exhaustive list of vsftpd options.
    # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
    # capabilities.
    #
    #
    # Run standalone? vsftpd can run either from an inetd or as a standalone
    # daemon started from an initscript.
    listen=YES


    #
    # Run standalone with IPv6?
    # Like the listen parameter, except vsftpd will listen on an IPv6 socket
    # instead of an IPv4 one. This parameter and the listen parameter are mutually
    # exclusive.
    #listen_ipv6=YES
    #
    # Allow anonymous FTP? (Beware - allowed by default if you comment this out).
    anonymous_enable=NO
    #
    # Uncomment this to allow local users to log in.
    local_enable=YES
    #
    # Uncomment this to enable any form of FTP write command.
    write_enable=YES
    #
    # Default umask for local users is 077. You may wish to change this to 022,
    # if your users expect that (022 is used by most other ftpd's)
    #local_umask=022
    #
    # Uncomment this to allow the anonymous FTP user to upload files. This only
    # has an effect if the above global write enable is activated. Also, you will
    # obviously need to create a directory writable by the FTP user.

    # go into a certain directory.
    dirmessage_enable=YES
    #
    # If enabled, vsftpd will display directory listings with the time
    # in your local time zone. The default is to display GMT. The

    # Enable this and the server will recognise asynchronous ABOR requests. Not
    # recommended for security (the code is non-trivial). Not enabling it,

    # By default the server will pretend to allow ASCII mode but in fact ignore
    # the request. Turn on the below options to have the server actually do ASCII
    # mangling on files when in ASCII mode.
    # Beware that on some FTP servers, ASCII support allows a denial of service
    # attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
