|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
and
|
|
.Nm .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:
|
|
.Pp
|
|
simple
|
|
.Bd -unfilled -offset indent
|
|
hostname [username]
|
|
.Ed
|
|
.Pp
|
|
or the more verbose
|
|
.Bd -unfilled -offset indent
|
|
[+-][hostname|@netgroup] [[+-][username|@netgroup]]
|
|
.Ed
|
|
.Pp
|
|
A
|
|
.Dq @
|
|
indicates a host by netgroup or user by netgroup.
|
|
A single
|
|
.Dq +
|
|
matches all hosts or users.
|
|
A host name with a leading
|
|
.Dq -
|
|
will reject
|
|
all matching hosts and all their users.
|
|
A user name with leading
|
|
.Dq -
|
|
will reject all matching users from matching hosts.
|
|
.Pp
|
|
Items are separated by any number of blanks and/or
|
|
tab characters.
|
|
A
|
|
.Dq #
|
|
indicates the beginning of
|
|
a comment; characters up to the end of the line are
|
|
not interpreted by routines which search the file.
|
|
.Pp
|
|
Host names are specified in the conventional Internet DNS
|
|
dotted-domains
|
|
.Dq .\&
|
|
(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.
|
|
.Pp
|
|
For security reasons, a user's
|
|
.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.
