.Dd Feb 1996 .Dt HOSTS.EQUIV 5 .Os FreeBSD .Sh NAME .Nm hosts.equiv , .Nm .rhosts .Nd trusted remote host name and user data base .Sh DESCRIPTION The .Nm hosts.equiv and .Nm .rhosts files contains information regarding trusted hosts and users on the network. For each host a single line should be present with the following information: simple d -unfilled -offset indent hostname [username] .Ed or the more verbose d -unfilled -offset indent [+-][hostname|@netgroup] [[+-][username|@netgroup]] .Ed

p A ``@'' indicates a host by netgroup or user by netgroup. A single ``+'' match all hosts or users. A host name with leading ``-'' will reject all matching hosts and all their users. A user name with leading ``-'' will reject all matching users from matching hosts.

p 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.

p Host names are specified in the conventional ``.'' (dot) notation using the .Xr inet_addr 3 routine from the Internet address manipulation library, .Xr inet 3 . Host names may contain any printable character other than a field delimiter, newline, or comment character.

p For security reasons, a users .Nm .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. .Sh EXAMPLES

p .Dl bar.com foo

p Trust user ``foo'' from host ``bar.com''.

p .Dl +@allclient

p Trust all hosts from netgroup ``allclient''.

p .Dl +@allclient -@dau

p Trust all hosts from netgroup ``allclient'' and their users except users from netgroup ``dau''. .Sh FILES l -tag -width /etc/hosts.equivxxx -compact t Pa /etc/hosts.equiv The .Nm hosts.equiv file resides in
