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.
