Been there, done that. Still, '-P' doesn't seem to work for me as
advertised. The translator dies immediately.

What really surprises me is that the ftp translator dies
_momentarily_, as if it even wouldn't bother to contact the server.

At the same time I've seen that I can ftp with it to a neighbouring
box (while any attempts to set up an ftp translator for any server out
in the Internet fail with 100 % reproducibility.

I wonder if there is any way to intercept the communication between
the ftp translator and the server...

Thanks,
