graphical ftp client that can copy/paste

[Pollywog <linux-debian@shadypond.com>]

I have to work with an ftp site that does not also have ssh or telnet access 
and I need to move files between directories.  gftp apparently does not have 
a feature to copy and paste files.  I tried it with the file manager and it 
also does not work (the "paste" menu is grayed out).  The command line client 
on my machine, the one that came with Debian, does not have the RNFR and RNTO 
commands in its repertoir.

Is there a way to do what I want to do without resorting to MS anything?

thanks
