RHOSTS(5)

NAME
rhosts, hosts.equiv - trusted remote users or hosts

SYNOPSIS
~user/.rhosts
/etc/hosts.equiv

DESCRIPTION
The per user .rhosts and the per system hosts.equiv files can be used to allow users to use rlogin or rsh without a password. The remote login services first check the system wide /etc/hosts.equiv file and then the ~user/.rhosts of the intended user. Both files contain lines of one of two forms:

    host
    host ruser

The first form tells that any user from host is allowed to login to this system under the same name. The second form allows ruser from host to login.

Under Minix host may be a pattern using * as a wildcard. One can use this, carefully one may hope, to allow an entire domain to log in. Host may also be an IP address, or a network specification in CIDR form, e.g. 172.16.102.64/27.

SEE ALSO
rlogin(1), rsh(1).

NOTES
Minix has no restrictions on becoming super-user remotely. Other systems usually require one to log in as a user and then use su to become root.

You must use fully qualified hostnames, it is not possible to omit the domain part.
