It works, not as good as I wish because when I look how me file (using ftp) is tranmitted (hash fonctionnality of any ftp client), it looks like my file is uploaded using big blocks of data with a delay between. So even if the file takes more time to be uploaded, my telnet session are slow. Maybe I should use the buffer functionnality, but I don't understand what is this functionnality. I have another problem I've seen today because I was doing some tests. I used the BW restiction as show before (the ipfw commands). But when I want to test my uploads without the pipes, I do a "ipfw flush" and after my upload is really slower, not usable... It looks like the rules are flushed (ipfw list) but my ftp data goes somewhere else... Any Idea ? David ROBERT (sorry for my english).
