HOWTO: Editing /etc/hosts

[FLeiXiuS]

Here is a quick how to, to edit your /etc/hosts file.
The $ represents a line of code you may enter in a terminal.

Open /etc/hosts with your favorite text editor. Remember to use sudo.


Format:
<IP> <HOSTNAME>.<DOMAIN> <ALIAS>

Example:
127.0.0.1 localhost.localdomain localhost


IP
Replace the <IP> with the IP of your system. If your running DHCP do not worry about editing this file. To detect your IP address run $ lsconfig Then browse for the connected interface (eth0, wlan0, etc)

Hostname
Replace the <HOSTNAME> to your systems hostname.

To view current hostname:
$ hostname

To change hostname:
$ sudo hostname 'enterhostname'
(without quotes)


Domain Name
The domain name can be anything you like unless it must be resolv, which then you must use /etc/resolv.conf. But thats another issue i'll cover later! :o

Alias
Alias are simply another way to combine a set of arguments. When you create a hosts file, its simply creating a list of hosts on the network, or locally. Its much easier to understand if you kept the alias the same as the hostname. It saves a lot of trouble with debugging and troubleshooting. But you are free to use whatever you like.


That should help you out. Please comment!

Nice. You can make shortcuts for webpages with alias
216.239.37.99 www.google.com gType ctrl+L,g,enter in firefox to go to google.

you can do the same more practically by giving a keyword to a bookmark, in firefox.
Just go to bookmars->manage bookmarks
and open the bookmark's properties, entering the keyword and
clicking OK.

this link describes more, quick searches, which in my opinion are great:

Would anyone know why this would not work on Edgy?

I'm trying to access my webserver in my LAN, however due to my firewall I cannot use the external address, I have to use my internal address to my DMZ.

I'd like to have my translation done like this HOST.DOMAIN = DMZ IP. It's very useful when looking at information posted on the web with the source on ur webserver.

victor@victor-laptop:~$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 victor-laptop
10.10.0.2 www.mysite.dyndns.org home
72.14.203.99 www.google.ca g

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts


The alias for google is also not working.

I also restarted my network and logged out and back in, but no doughnut..

sudo /etc/init.d/networking restart


Thanks,


Vic.
