The data is stored in a file called +.Pa /etc/ethers +in the following format: +.Bd -unfilled -offset indent +.Pa ethernet-address fully-qualified-host-name +.Ed +.Pp +Items are separated by any number of blanks and/or +tab characters. A ``#'' at the start of a line indicates the +beginning of a comment that extends to the end of the line. A ``+'' at +the start of a line will cause the +.Xr ethers 3 +library functions to use data stored in the NIS +.Pa ethers.byname +and +.Pa ethers.byaddr +maps in addition to the data in the +.Pa /etc/ethers +file. +.Pp +An ethernet address is expressed in +.Tn ASCII +form as "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/ethers +database should correspond to entries in the +.Xr hosts 5 +file. +.Pp +The +.Fn ether_line +function in the standarc C library can be used to break individual +lines in the +.Pa /etc/ethers +database into their individial components: a binary ethernet address +stored as an +.Pa ether_addr +structure, and a hostname stored as a character string. +.Sh FILES +.Bl -tag -width /etc/services -compact +.It Pa /etc/ethers +The +.Nm ethers +file resides in +.Pa /etc . +.El +.Sh SEE ALSO +.Xr ethers 3 +.Sh HISTORY +The +.Nm ethers +format is based on the format used in SunOS 4.1.x. -- cgit v1.1
