[Techtalk] /etc/hosts

[k.clair]

Putting it in /etc/hosts I believe will enable the machine to recognize
itself by a hostname instead of an IP. You can also reset the hostname
using the "hostname" command. Without an argument, hostname will return
the hostname, but given an argument (a hostname) it will set the
hostname.

In terms of other computers on the internet recognizing your computer by
its hostname rather than by the IP, you will probably need to get
someone who does DNS (most likely the service provider) to provide you 
with a PTR record which would map
the IP address to the hostname (which would obviously need to be a fully
qualified domain) of your computer.  This mostly comes up when you are
trying to connect to some other service on another computer somewhere
from your computer... often the other computer will do a reverse lookup
on your IP to make sure you are who you say you are.

- I really do appreciate any help.
