localhost changed to (none)

LukeOrland · 2010-01-12 23:43:02

post-upgrade or perhaps after some careless configuration editing, my system started crashing as soon as X starts.

My first troubleshooting step is to identify why the localhost is now coming up as (none) instead of the value I set in /etc/hosts.

my /etc/hosts contains the following:

#
# /etc/hosts: static lookup table for host names
#

#<ip-address>    <hostname.domain.org>    <hostname>
127.0.0.1        localhost.localdomain    localhost arch_dv1000

# End of file

What other config files could impact the name of localhost?

correct. i had the HOSTNAME line commented out in /etc/rc.conf for some reason. dumb mistake. Thanks!

Hi!

I have exactly the same problem except my Hostname line isn't commented. I have the same name in rc.conf and hosts but when I open the console, there is: biniou@(none)
What can I do?

Hostname is set at startup while the system runs /etc/rc.sysinit (which itself is run from /etc/inittab).

rc.sysinit sources /etc/rc.conf and inside it you have:

if [ "$HOSTNAME" != "" ]; then
    status "Setting Hostname: $HOSTNAME" /bin/hostname $HOSTNAME
fi

So along the line something is going wrong. You can:

Check that rc.sysinit is in /etc/inittab.
Insert a debug line in /etc/rc.sysinit before/after above lines, for example:

echo "Before if: HOSTNAME = $HOSTNAME" ; sleep 5

Meanwhile you can execute on the command line:

/bin/hostname WhateverName

Thanks for this answer.

I checked my rc.sysinit and there is no lines

 if [ "$HOSTNAME" != "" ]; then
    status "Setting Hostname: $HOSTNAME" /bin/hostname $HOSTNAME
fi

I also tried in root

 /bin/hostname Laptop

It tells me:

[root@(none) ~]# kdeinit4: preparing to lauch /usr/lib/kde4/libexec/kdontchangethehostname
Warning: No session management specified

Edit: I don't have this message if I stop wicd daemon.

I'm wondering where I screwed up during the installation...I never had this problem before.

biniou,

pacman -Qo /etc/rc.sysinit

outputs:

/etc/rc.sysinit is owned by initscripts 2010.06-2

Start by reinstalling initscripts, and see if things start to make sense.

However, /bin/hostname Laptop should have worked.

bin/hostname is owned by net-tools 1.60-14

Yeah! You rock Mektub, it worked!

Thanks again for your help!
