LinuxQuestions.org - [SOLVED] -current changing hostname

-current changing hostname

Did a fresh install of -current today and have a weird situation.

During install I set the hostname to "2540p" and when I rebooted I noted that my hostname was changed back to the default "darkstar".

I ran netconfig and changed it back to "2540p" and rebooted, no dice, it was back to "darkstar" again.

Code:

sqdnguns @ darkstar  ~ >> cat /etc/hosts

#

# hosts        This file describes a number of hostname-to-address

#              mappings for the TCP/IP subsystem.  It is mostly

#              used at boot time, when no name servers are running.

#              On small systems, this file can be used instead of a

#              "named" name server.  Just add the names, addresses

#              and any aliases to this file...

#

# By the way, Arnt Gulbrandsen <agulbra@nvg.unit.no> says that 127.0.0.1

# should NEVER be named with the name of the machine.  It causes problems

# for some (stupid) programs, irc and reputedly talk. :^)

#



# For loopbacking.

127.0.0.1              localhost

127.0.0.1              2540p.sqdnguns.com 2540p



# End of hosts.



sqdnguns @ darkstar  ~ >> cat /etc/HOSTNAME

2540p.sqdnguns.com

sqdnguns @ darkstar  ~ >>

Any idea as to what I am doing wrong?

What is the output of the hostname command?

What is the output of the hostname command after you have run netconfig?

Maybe -current is different but 13.37 sets the hostname in /etc/rc.d/rc.S from the contents of /etc/HOSTNAME. Would you like to (make a backup of rc.S and) add some debugging to rc.S?

Code:

# Set the hostname.

if [ -r /etc/HOSTNAME ]; then

  echo "/etc/HOSTNAME is readable and contains '$(cat /etc/HOSTNAME)'" >> /tmp/rc.S.log

  echo "Input to hostname command: $(cat /etc/HOSTNAME | cut -f1 -d .)" >> /tmp/rc.S.log 

  /bin/hostname $(cat /etc/HOSTNAME | cut -f1 -d .)

else

  # fall back on this old default:

  echo "/etc/HOSTNAME is not readable: '$(ls -l /etc/HOSTNAME)'" >> /tmp/rc.S.log

  echo "darkstar.example.net" > /etc/HOSTNAME

  /bin/hostname darkstar

fi

Found this:

Code:

# /etc/NetworkManager/NetworkManager.conf

#

# See NetworkManager.conf(5) for more information on this file



[main]

plugins=keyfile

dhcp=dhcpcd



[keyfile]

hostname=darkstar

I am not familiar with Network Manager so I need to read up on it.

Not related to original topic but I see that when I drop into Run Level 3, I lose my network connectivity.

It appears that it was NetworkManager.conf

I edited the hostname and it appears to have fixed it.

Is this a "bug" with Networkmanager?

I will not mark this as solved until it is determined to be end user error or an actual bug.

Marked as solved. Pat fixed this in the -current updates released tonight!

Code:

n/network-scripts-13.42-noarch-1.txz:  Upgraded.

  Add a 'NetworkManager' option to netconfig.

  Copy the hostname into NetworkManager.conf.  Thanks to SqdnGuns.
