Ricardo, | Active FTP connection from behind a router/firewall/etc? I had the same | problem last days. Just tell dupload to try passive FTP (and upload some | .commands file before that to remove the 0 bytes freefem_3.5.7-3.tar.gz) thanks for the help the *.commands stuff worked fine the passive flag was the solution!
