|
|
.Nd IEEE EUI-64 address database
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
database contains information regarding known IEEE EUI-64s of hosts.
|
|
The data is stored in a file called
|
|
.Pa /etc/eui64
|
|
in the following format:
|
|
.Bd -ragged -offset indent
|
|
.Em EUI-64 host-name
|
|
.Ed
|
|
.Pp
|
|
Items are separated by any number of blanks and/or
|
|
tab characters.
|
|
A
|
|
.Ql #
|
|
at the start of a line indicates the
|
|
beginning of a comment that extends to the end of the line.
|
|
Valid lines may also contain comments.
|
|
A
|
|
.Ql +
|
|
at the start of a line will cause the
|
|
.Xr eui64 3
|
|
library functions to use data stored in the
|
|
NIS
|
|
.Pa eui64.byname
|
|
and
|
|
.Pa eui64.byid
|
|
maps in addition to the data in the
|
|
.Pa /etc/eui64
|
|
file.
|
|
.Pp
|
|
An EUI-64 is expressed in
|
|
.Tn ASCII
|
|
form as
|
|
.Qq x-x-x-x-x-x-x-x
|
|
where
|
|
.Ar x
|
|
is a hexadecimal value between 0x00 and 0xFF.
|
|
The address values
|
|
should be in network order.
|
|
Hostnames specified in the
|
|
.Pa /etc/eui64
|
|
database should correspond to entries in the
|
|
.Xr hosts 5
|
|
file.
|
|
.\" .Pp
|
|
.\" The
|
|
.\" .Fn eui64_line
|
|
.\" function in the standard C library can be used to break individual
|
|
.\" lines in the
|
|
.\" .Pa /etc/eui64
|
|
.\" database into their individual components: a binary EUI-64 is
|
|
.\" stored as an
|
|
.\" .Pa eui64_addr
|
|
.\" structure, and a hostname stored as a character string.
