Sorry, my mistake! My line in the ftp script:

	ftp.retrlines('LIST ', lines.append)

has a space after the LIST command. It worked well on one host, but not
on another. By closing it:

	ftp.retrlines('LIST', lines.append)

it works OK. I was a bit flabbergasted by the 'command not understood'
error...
