HOSTS.EQUIV(5) FreeBSD 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 Internet 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".
