Granted I probably could download the open source project to investigate myself, but I figured that would be a trifle unethical, so instead I'll ask here in the hopes that someone might be willing to point out my flaws. When interpreting commands as they are sent and retrieving the responses from the FTP server, I have found that FileZilla works flawlessly, never hiccuping at all as my own code is prone to do. Currently I'm trying to develop my own automated upload script application, which I be more that happy to use FileZilla for should it ever incorporate any automation. Regardless of such I am still rather confused as to why FileZilla can access the same FTP sites without any problem that my own client has issues with.When sending the LIST command i have found that with more recent FTP server engines, it is possible to receive either a 150 or 125 return command. At first this was a mere annoyance, but what happened next was even more confusing. On the one server that I connect to, when i transmit the LIST command the response code 125 is returned almost immediately followed by the appropriate 226 Transfer Complete command. Nearly before the client class has a chance to instantiate the data socket. I start with the PASV command, followed by the LIST command, and upon receiving the 150/125 codes I start the data socket transfer. (using windows sockets in .Net). THis server happens to be a WIndows_NT server, though i'm not sure it makes any difference. The other server I've been testing with my code is a UNIX server, which in contrast returns with the 150 response code to my LIST command, additionally returning the LIST resFtp 530
