Strange loopback entries in /etc/hosts

Passions · 04-13-2007, 08:23 PM

Hi,

The way how I understand loopback entries in /etc/hosts should be the format:

127.0.0.1 localhost.localdomain localhost

But on some of my computers I will see:

127.0.0.1 localhost.localdomain <hostname> localhost

or even...

127.0.0.1 <hostname> localhost.localdomain localhost

Does anyone know why this is happening?

Should I keep the hostname in there or remove it??

Thanks!!

From 'man hosts':

Quote:

For each host a single line should be present with
the following information:

IP_address canonical_hostname [aliases...]

Fields of the entry are separated by any number of blanks and/or tab
characters.

In other words, multiple aliases are permitted.
