Solaris 2 comes out of the box a heck of a lot more secure than Solaris 1. There is no '+' in the hosts.equiv. root logins are not allowed anywhere except the console. All accounts require passwords. In order to allow root logins over the net, you need to edit the /etc/default/login file and comment out or otherwise change the CONSOLE= line.
This file's CONSOLE entry can actually be used in a variety of ways:
1) CONSOLE=/dev/console (default) - direct root logins only on console
2) CONSOLE=/dev/ttya - direct root logins only on /dev/ttya
3) CONSOLE= - direct root logins disallowed everywhere
4) #CONSOLE (or delete the line) - root logins allowed everywhere
/etc/hosts.equiv is still supported, but there is no default.
