Setting The Hostname

Code:

cho server1.example.com > /etc/hostname
/bin/hostname -F /etc/hostname

as it shows is the how to ..perfect setup! the thing is that i don't understand what it does exactly!

i replaced server1.example.com with the one i use ( ady.xhost.ro ).
hostname shouldn't be replaced with the nostname name i gave during installation ( e.g.: host1 )?
i followed the 2 stepts and no message replied! is that good or what?

 

It gives your system a new hostname.

That's ok.

Which installation?

That's normal. You can check your new hostname by running

Code:

hostname

or

Code:

hostname -f

 

The Perfect Setup - Debian Sarge (3.1) - Page 3 installation.
i ran " hostname " and it worked
i ran " hostname -f " and it replied

Code:

hostname: hostname lookup failure

...why is that? does it need to be connected to the internet to reply a positive answer?
thx very much falko! & till! you've helped me so much! thx again!

 

What's the output of

Code:

hostname

?

What's in /etc/hosts?

 

when i run " hostname " the output is

Code:

upload4me.ws43.com

as i intented to be.
when i run " nano hostname " ( i don't know if this is the way i should ).. thers is nothing there ( inside the file? )

in /etc/hosts , suppose using

Code:

nano /etc/hosts

there is :

Code:

127.0.01   localhost.localdomain   localhost   adeekos

# 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

...allthough i don't know what each mean

 

I have this in /etc/hosts

Code:

127.0.0.1 localhost.localdomain localhost alcon

# 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

Would it be correct if I added this line? Change X with corresponding numbers:

Code:

200.104.X.X mundohosting.cl

Or would it be necessary to put subdomain.mundohosting.cl ? Note that 200.104.X.X is my public IP.
Many thanks.
