.SH SYNOPSIS

|
||
|
|
.SH DESCRIPTION
|
||
|
|
The hosts database lists the IP addresses and the hostnames that translate
|
||
|
|
to these IP addresses. It is used by
|
||
|
|
.BR nonamed (8)
|
||
|
|
in a network without name servers. A simple
|
||
|
|
.B /etc/hosts
|
||
|
|
may look like this:
|
||
|
|
.PP
|
||
|
|
.RS

|
|

These two entries give names to two IP addresses. The file may contain
|
||
|
|
comments marked with '#'.
|
||
|
|
.PP
|
||
|
|
You can have aliases (more hostnames on the same line) to give a machine
|
||
|
|
more than one name, like
|
||
|
|
.BR www ,
|
||
|
|
if you run a web server on one.
|
||
|
|
.PP
|
||
|
|
If your PC is Internet connected then you can specify the name server(s)
|
||
|
|
to get more information from with %nameserver entries:
