About user equivalence

User equivalence allows a user to use rlogin(1tcp) to log in to an equivalent account on another host without entering a password. SCOadmin managers require this equivalence to allow you to manage other systems over the network using the Open Host selection. You can establish user equivalence between:

• individual remote/local account pairs by using the Accounts Manager to alter a user's $HOME/.rhosts file to add the remote host and account

• a remote account and all local accounts except root (and other non-individual accounts such as bin), by editing /etc/hosts.equiv to add the remote host and account

• all accounts on a remote host and all local accounts except root (and other non-individual accounts) by editing /etc/hosts.equiv to add only the remote host name

Configuring the files manually allows you to set equivalence between accounts with different logins. The simplest option is to use accounts with the same name as described in ``Setting remote access for a user''.

If there are entries in both .rhosts and /etc/hosts.equiv for the same host or host/account combination, the entry from /etc/hosts.equiv determines the extent of user equivalence. For more information, see rhosts(4tcp).
