That is because 'bin.tar.gz' is a parameter to the '-f' option.  Really,
what you are doing is:

tar -z -x -v -p -f bin.tar.gz
tar -z -x -v -f -p bin.tar.gz

The -p option doesn't take a paremeter.  -f take as a parameter the file
you want to extract...

Type "prompt" - it will say "interactive mode off", and then it will
silently get everything matched.  I believe there is still some security
issues with the ftp getting things you don't really want though (like
../.rhosts or something). 

Hope this helps,
