Note however that the "echo" above has to be done by "anotheruser"; you
can't do it. Rsh is insecure, but it at least verify that ONLY anotheruser
is able to write to its own "~/.rhosts" :-)
And if you'r e fool enough to do this, you may as well do that:
$ echo "my password" > ~/THIS_IS_MY_PASSWORD
$ chmod a+r ~/THIS_IS_MY_PASSWORD
