Can't the client just specify a filename of "/home/cp_ru/filename"?

That seems to do more or less what you want, but it points out a
gaping security hole in the server; the client could specify a
filename of, say, "/etc/passwd", which would be bad.  (I assume
the server is running as root so it can bind to port 510.)

Why not just use ftp or sftp?
