    [Solved] Slow download from own FTP.Server (vsftpd + proftpd) -- Update

    -- Update V3 --

    Hi Guys,

    I think I've solved the problem. Now I have full download speed with both proftpd and ( my favorite ) vsftpd. Also did I limit the passive port range to a normal size.
    And now I'm pleased with everything.

    As I thought, after many try and error, the problem was that I didn't enabled a Passive Port Range in my firewall and in the .conf of both programs.


    -- Update V3--


    -- Update V2 --

    After I enabled a port range for the passive ports it seems that everything works finde now. But my question now: Can I specify the port range a little better ? Now I have a range of 49152:65534. The same as in the proftpd.conf.

    And the second: I have a upload of 100Mbit on my server. When I, for example download something it goes with full speed, when a friend of mine download the same thing my download goes down. I dont understand this. If my friend and I have a dl-speed of 16Mbit then there must be ca. 60Mbit left. But I get a dl-speed of ca. 8Mit or less.

    I tried a direct upload with the rapidshare remote-upload and there I got 90 - 95 Mbit. So It can't really lie on the upload, right ?

    Sorry for the English ... it's late and I'm going to sleep now :)

    I've found out that I have full speed when I go with WinSCP over SFTP.
    Do anyone know why I have problems with the normal FTP ?

    -- End-Update --


    I've got a real big problem. In fact if I try to download a large file ( like a few 100MB or 1GB ) from my own Server via FTP or Browser the download speed is awful slow.
    It doesn't matter what kind of FTP-Prog I use neither vsftpd nor proftpd give full speed. I've searched the Forum and found a lot of threads about this topic.
    I tried every possibility and now I use vsftpd. The issue with vsftpd is, that if I make a fresh vsftpd installation and make the adjustments in the config ( like local_enable=YES and local_umask=022 ) the first download via FTP or Browser is in full speed, but after that the speed goes down and it's slow again (normaly 16000 kb and after the first download only 100 - 250 fluctuating ).
    I've changed also the FTP-Config in the Ispconfig Panel to vsftpd and also the path to the config file.

    I am at my wit's end. And I hope you can help me.

    The only problem is the download - my upload is in full speed.

    Here is my vsftpd.conf

    Code:
    # 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.
    #anon_upload_enable=YES
    #
    # Uncomment this if you want the anonymous FTP user to be able to create
    # new directories.
    #anon_mkdir_write_enable=YES
    #
    # Activate directory messages - messages given to remote users when they
    # go into a certain directory.
    dirmessage_enable=YES
    #
    # Activate logging of uploads/downloads.
    xferlog_enable=YES
    #
    # Make sure PORT transfer connections originate from port 20 (ftp-data).
    connect_from_port_20=YES
    #
    # If you want, you can arrange for uploaded anonymous files to be owned by
    # a different user. Note! Using "root" for uploaded files is not
    # recommended!
    #chown_uploads=YES
    #chown_username=whoever
    #
    # You may override where the log file goes if you like. The default is shown
    # below.
    #xferlog_file=/var/log/vsftpd.log
    #
    # If you want, you can have your log file in standard ftpd xferlog format
    #xferlog_std_format=YES
    #
    # You may change the default value for timing out an idle session.
    #idle_session_timeout=600
    #
    # You may change the default value for timing out a data connection.
    #data_connection_timeout=120
    #
    # It is recommended that you define on your system a unique user which the
    # ftp server can use as a totally isolated and unprivileged user.
    #nopriv_user=ftpsecure
    #
    # Enable this and the server will recognise asynchronous ABOR requests. Not
    # recommended for security (the code is non-trivial). Not enabling it,
    # however, may confuse older FTP clients.
    #async_abor_enable=YES
    #
    # 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
    # predicted this attack and has always been safe, reporting the size of the
    # raw file.
    # ASCII mangling is a horrible feature of the protocol.
    #ascii_upload_enable=YES
    #ascii_download_enable=YES
    #
    # You may fully customise the login banner string:
    #ftpd_banner=Welcome to blah FTP service.
    #
    # You may specify a file of disallowed anonymous e-mail addresses. Apparently
    # useful for combatting certain DoS attacks.
    #deny_email_enable=YES
    # (default follows)
    #banned_email_file=/etc/vsftpd.banned_emails
    #
    # You may restrict local users to their home directories.  See the FAQ for
    # the possible risks in this before using chroot_local_user or
    # chroot_list_enable below.
    #chroot_local_user=YES
    #
    # You may specify an explicit list of local users to chroot() to their home
    # directory. If chroot_local_user is YES, then this list becomes a list of
    # users to NOT chroot().
    #chroot_list_enable=YES
    # (default follows)
    #chroot_list_file=/etc/vsftpd.chroot_list
    #
    # You may activate the "-R" option to the builtin ls. This is disabled by
    # default to avoid remote users being able to cause excessive I/O on large
    # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
    # the presence of the "-R" option, so there is a strong case for enabling it.
    #ls_recurse_enable=YES
    #
    #
    # Debian customization
    #
    # Some of vsftpd's settings don't fit the Debian filesystem layout by
    # default.  These settings are more Debian-friendly.
    #
    # This option should be the name of a directory which is empty.  Also, the
    # directory should not be writable by the ftp user. This directory is used
    # as a secure chroot() jail at times vsftpd does not require filesystem
    # access.
    secure_chroot_dir=/var/run/vsftpd
    #
    # This string is the name of the PAM service vsftpd will use.
    pam_service_name=vsftpd
    #
    # This option specifies the location of the RSA certificate to use for SSL
    # encrypted connections.
    rsa_cert_file=/etc/ssl/certs/vsftpd.pem
