I am posting so that others might learn.  I will send mail to Dan, as he

/etc/hosts.equiv performs the same function as ~/.rhosts.  It tells the
system which hosts are to be trusted.  When a host listed in
/etc/hosts.equiv connects, the daemon assumes that similarusernames on both
machines are allowed to connect.  ~/.rhosts lists machines and users that
are allowed to connect to this account.

In your setup, having vs1 in the hosts.equiv on myhost doesn't help.  What
would happen if I put the name of your machine in my hosts.equiv and su'ed
to barrett.  I would then be able to connect to your account without a
password.

Make sure that all three machines have the other two in their hosts.equiv.
This should solve the problem.
