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

/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.
