/etc/hosts correct format ?

TreeMinds · 2007-09-01 11:32:58

What is the correct format for the /etc/hosts file ? Found in ArchWiki 2 different
here : http://wiki.archlinux.org/index.php/Configuring_network
127.0.0.1 banana.localdomain banana

& here : http://wiki.archlinux.org/index.php/LAMP
127.0.0.1 localhost.localdomain localhost banana

Both of them are correct?

yes

first comes the ip-address, then a list of names

TreeMinds · 2007-09-01 11:40:05

So in the second one you have 2 names localhost & banana
and in the first you have only banana for hostname?
Thanks a lot.

You should always have localhost and localhost.localdomain - add anything else you need after those.

I experienced lag when loading webpages when I had separate entries for /etc/hosts. When I put all entries on the same line, everything works nicely. Like in the beginner's guide in the wiki:

127.0.0.1 yourhostname.domain.org localhost.localdomain localhost yourhostname

FWIW

so if hostname is mm "hello"

it would be

127.0.0.1 hello.domain.org localhost.localdomain localhost hello

right? : o

i'd put something like this into the file:
127.0.0.1 localhost localhost.localdomain hostname hostname.localdomain

but i think that the localdomain stuff isn't needed at all.

Actually it is needed for program compatibility. Certain programs will lag when opening them if the localhost syntax is wrong.

Yes. I suppose YMMV, but I have had 100% success with this syntax, gleaned from the beginner's guide and forum.

These are simple questions, but I have not found the answers anywhere.

First, I can put anything I want for the hostname in rc.conf, right? That is kind of shown here in this thread, but I want to make sure, because that seems odd to me.

Next, what do I replace "localhost" and "localdomain" with? Do literally leave them typed just as your examples show?

Last, how can I tell if I have a static IP or a dynamic IP? Does it have to do with the hardware I have or my Internet provider?

tomk · 2007-09-04 06:32:12

You need the actual words "localhost" and "localhost.localdomain" - everything else is at the mercy of your imagination.

I made it like this:
127.0.0.1 banana.ufo.org localhost.localdomain localhost banana
10.0.0.2 banana.ufo.org banana

Eliteforce · 2007-09-04 11:19:20

so what does banana resolve to now? 127.0.0.1, 10.0.0.2 or both?

TreeMinds · 2007-09-04 11:57:12

I dont know man. Somewhere I saw that (if u have static ip do 2nd line with it)
What do u suggest maybe:
127.0.0.1 localhost.localdomain localhost
10.0.0.2 banana.ufo.org banana
?

Typically if you have a dynamic IP you would want only the 127.0.0.1 line. if you have a static IP you want to add the 2nd line. So assuming 10.0.0.2 is your static IP, this is the correct format.
Also the last entry in the file is the one that will be resolved...So for example, appending banana to the 127.0.0.1 line, when you still have the 10.0.0.2 entry effectively does nothing. banana will still resolve to 10.0.0.2
