FTP connection problem

[serje]

Hi, I have some problems with Total's FTP:

Lock at the server's log:

Well, log looks fine.
So where is the problem ?

It looks like you are using PWD for "keep alive", but the server sees this and terminates the connection anyway after the timeout. You either need to increase the timeout on the server, or use LIST for keep alive (quite rude).
