Cannot set hostname

Hello, recently I moved to a different place, and changed my ISP aswell. Now I'm using the router provided by my new ISP. My problem is, that unlike with the previous ISP the hostname specified in the rc.conf file isn't set correctly.
The corresponding part of my rc.conf:

# -----------------------------------------------------------------------
#
# HOSTNAME: Hostname of machine. Should also be put in /etc/hosts
#
HOSTNAME="skynet"

[...]

interface=eth0
address=
netmask=
broadcast=
gateway=

I've been suggested to add the hostname to /etc/hosts. It didn't work. My /etc/hosts:

[zyxon@dhcppc0 ~]$ cat /etc/hosts
#
# /etc/hosts: static lookup table for host names
#

#<ip-address>	<hostname.domain.org>	<hostname>
127.0.0.1	localhost.localdomain	localhost myhost
127.0.0.1	localhost.localdomain	skynet 
127.0.0.1	skynet.localdomain	localhost skynet 
::1		localhost.localdomain	localhost

# End of file

And the hostname is dhcppcN insted of skynet. How can I use the hostname skynet again?

Re: Cannot set hostname

Instead of

127.0.0.1	localhost.localdomain	localhost myhost
127.0.0.1	localhost.localdomain	skynet 
127.0.0.1	skynet.localdomain	localhost skynet 

use

127.0.0.1	localhost.localdomain	localhost skynet

Thanks for the reply. Still doesn't work.

[zyxon@dhcppc0 ~]$ cat /etc/hosts

#<ip-address>	<hostname.domain.org>	<hostname>
127.0.0.1	localhost.localdomain	localhost skynet
::1		localhost.localdomain	localhost

# End of file

Re: Cannot set hostname

What output do you get when you type

hostname

in a terminal?

And what's inside your /etc/conf.d/dhcpcd file?

Hostname gives "command not found" message.

[zyxon@dhcppc0 ~]$ hostname
bash: hostname: parancs nem található

I have an unedited dhcpcd config file:

[zyxon@dhcppc0 ~]$ cat /etc/conf.d/dhcpcd 
#
# Arguments to be passed to the DHCP client daemon
#

DHCPCD_ARGS="-q"

hostname is provided by inetutils in [core]

Re: Cannot set hostname

Thanks Lars Stokholm and b4data. Output of hostname is:

[zyxon@dhcppc0 ~]$ hostname 
dhcppc0

Re: Cannot set hostname

Take a look at this, the case seems identical. Try modifying dhcpcd.conf the same way, ie. by removing 'host_name', so the line looks like 'option domain_name_servers, domain_name, domain_search'.
