I have a vsftp server hosted on custom dyndns site. We have a 4mb
ADSL connection. When I tried to download the files from the ftp
server with wan IP address or the dyndns address it downloads some
files and disconnects. Please find below an extract from the log file
(ace ftp client). I would appreciate if someone could guide me,
possibly with a solution for this problem.
Many thanks

Rajeev,
I've been chasing this same problem for a couple of years now. It seems
to happen the most often when first the connection is a fast connection
and second when there are a lot of files to transfer. I've reduced the
number of concurrent connections in my ftp client. I've done passive and
port modes and I still don't know what is causing this but it is
extremely irritating.
If you find a solution, please post it back to this list for others to
learn.
Thanks,
John Hinton
