Because it's more `secure', and firewalls are happy with it.
However, it is a bug in that our ftp is supposed to `automatically' fall
back to active mode by default. However, it is not doing it in the case
above because the PASV command was successful, yet the actual transfer
attempt resulted in an error. This should be fixed.
