Hostname disappeared

I wasn't sure if I should've put this here or in the network forum, but since I am a newbie to Archlinux I'll post it here.

I installed Arch today, following the tutorial on the wiki, and everything seemed to be working smoothly.  After a reboot, after installing a LXDE and rebooting, however:

My hostname seems to have disappeared, or in some way unable to set.

When I boot up and get to the login prompt I get:

Arch Linux (Core Dump) 2.6.25-ARCH    ((none)) (vc/1)

(none)  login:

once I've logged in, my prompt agrees with the login, there is no hostname:

[user@(none) ~]$

HOSTNAME is set properly in both /etc/rc.conf and /etc/hosts, yet the hostname stays as (none).

If I type hostname in the prompt, I get the same "(none)", even if I try to set it manually with hostname=myhost.

Anyone got a suggestion?

Thanks for your help

Re: Hostname disappeared

That's strange as just specifying it in /etc/rc.conf should do it (as /etc/rc.sysinit sets it up from there)...

You don't need /etc/hosts for setting up hostname, it's there to *associate* ur IP with ur hostname.

Thanks for your reply

It's specified in /etc/rc.conf, and associated to my ip (nothing else) in /etc/hosts.

Post your /etc/rc.conf and /etc/hosts, just in case it's a syntax error?

193... myhost.domain.org myhost
# End of file

As you can see I'm using a static ip, which I have to in order to access the net. And no, it doesn't actually say 193... in the files.

Re: Hostname disappeared

I don't know if this is helpful, but you have myhost set as your host name in rc.conf and localhost set under <hostname.domain.org>. I would set them to match. For instance, my machine is called iasE. So in rc.conf I have HOSTNAME="iasE" and /etc/hosts I have 127.0.0.1   iasE.localdomain      iasE localhost

Re: Hostname disappeared

Tried that just now. No improvement, unfortunately.

Why can't I even set it manually? is something continuously making sure I've got no hostname?

Re: Hostname disappeared

Please post your hosts and rc.conf again - you said you tried what skottish suggested?

Re: Hostname disappeared

The only change is the line skottish told me about.

127.0.0.1        localhost.localdomain    localhost myhost

is now:

127.0.0.1        myhost.localdomain    localhost myhost

Re: Hostname disappeared

Did you reboot after making the changes?

Re: Hostname disappeared

Try setting something other than "myhost",

Re: Hostname disappeared

Just had a look at your rc.conf. There seems to be a syntaxerror indeed:

CONSOLEFONT="lat-1-16.psfu.gz

has no closing quote. I guess thats it.

Re: Hostname disappeared

I wish I'd waited with reinstalling it all until this was posted 

Thanks anyway.

Re: Hostname disappeared

Ouch.  Oh well, at least now you know that sometimes it's the smallest (and seemingly unrelated) things that can make or break a system. The ever-elusive missing quotation is a common one.
