    I have recently noticed that I cannot have more then one simultaneous FTP connection. If I have one connection open, then try to open another one, the FTP client hangs until I close the first connection.

    Also, when trying to upload files larger that around 20mb, the upload starts again or the connection cuts of. The support team for my hosting said there may be a setting in Plesk to allow more then one connection or keep uploads from timing out.

    Hi,

    As far as I know there are no such settings in Parallels Plesk panel as to limit number of simultaneous connections or set transfer timeout.

    So you can configure this in proftpd configuration.
    For simultaneous connections:
    http://www.proftpd.org/docs/directives/linked/config_ref_MaxInstances.html
    http://www.proftpd.org/docs/directives/linked/config_ref_MaxClients.html

    and if proftpd is running through xinetd then it is worth setting
    instances = UNLIMITED

    in /etc/xinetd.d/ftp_psa


    For transfer timeout:
    http://www.proftpd.org/docs/directives/linked/config_ref_TimeoutIdle.html
    http://www.proftpd.org/docs/directives/linked/config_ref_TimeoutStalled.html

    Hope this helps.

    Thanks.

    Actually "instances" was already set to UNLIMITED.

    However, in Plesk / Security Policy / Secure FTP, i set "Allow only non-secure FTP connections. Do not use FTPS" instead of "Allow both secure FTPS and non-secure FTP connections" and now we can have several active FTP sessions on the same account at the same time :)
    So it SEEMS to be the solution (...)
