Problem in connecting to pyftpdlib from remote FTP client #519

Closed ebrahim-abbasi closed 4 years ago

ebrahim-abbasi commented 4 years ago

Dear all,

I am running pyftpdlib on ubuntu with python 3.6 in a virtual environment. When connecting from a local FTP client, it works perfectly. But when connecting from a remote FTP client I am getting the following error:

unhandled exception in instance <DTPHandler(id=139896849234072, addr='192.168.33.101:52720', user='ftptest')>
    Traceback (most recent call last):

        data = first[:obs]
    TypeError: 'BufferedIteratorProducer' object is not subscriptable

    During handling of the above exception, another exception occurred:

I also disabled the firewall.

Thanks for any help
