I am having an ongoing issue cannot wrap my head around, ftp (using cmd FTP prompt) to send a 400k text file and when they agree to send the file, the client sends the file over port 20 and .00002 seconds sends a reset without even allowing the receiving end to send an ack back. This results in only a partial file being sent. When I use an FTP client I get "an existing connection was forceabley closed by the remote host. The packet looks like the image below.
