The main problem with /etc/hosts.equiv is that it is a VERY bad security hole.

By using IP spoofing, anyone can break into your system. There are other good ways to check the users when the login.

If someone can login as one of your users via /etc/hosts.equiv that could be very dangerous.

Is /etc/securetty an option?

HOSTS.EQUIV(5)						      BSD File Formats Manual						    HOSTS.EQUIV(5)

NAME
hosts.equiv, .rhosts -- trusted remote host and user name data base DESCRIPTION
The hosts.equiv and .rhosts files contain information regarding trusted hosts and users on the network. For each host a single line should be present with the following information: simple hostname [username] or the more verbose [+-][hostname|@netgroup] [[+-][username|@netgroup]] A ``@'' indicates a host by netgroup or user by netgroup. A single ``+'' matches all hosts or users. A host name with a leading ``-'' will reject all matching hosts and all their users. A user name with leading ``-'' will reject all matching users from matching hosts. Items are separated by any number of blanks and/or tab characters. A ``#'' indicates the beginning of a comment; characters up to the end of the line are not interpreted by routines which search the file. Host names are specified in the conventional Internet DNS dotted-domains ``.'' (dot) notation using the inet_addr(3) routine from the Inter- net address manipulation library, inet(3). Host names may contain any printable character other than a field delimiter, newline, or comment character. For security reasons, a user's .rhosts file will be ignored if it is not a regular file, or if it is not owned by the user, or if it is writable by anyone other than the user. FILES
/etc/hosts.equiv The hosts.equiv file resides in /etc. $HOME/.rhosts .rhosts file resides in $HOME. EXAMPLES
bar.com foo Trust user ``foo'' from host ``bar.com''. +@allclient Trust all hosts from netgroup ``allclient''. +@allclient -@dau Trust all hosts from netgroup ``allclient'' and their users except users from netgroup ``dau''. SEE ALSO
