[FIXED] bind9 is running bind9 status reports failed!

bind9 runs in a chroot environment on lenny. The service can be started as usual:

# /etc/init.d/bind9 start
Starting domain name service...: bind9.

Let’s check bind9 status:

# /etc/init.d/bind9 status
bind9 is not running failed!

Well, the first thing I did was to check the log file, in which I found no error related to named. So I tried another way to check the status:

# rndc status
version: 9.6-ESV-R3
CPUs found: 1
worker threads: 1
number of zones: 17
debug level: 0
xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is OFF
recursive clients: 0/0/1000
tcp clients: 0/100
server is up and running

I was convinced that dns service was running. So what went wrong? It must be something in the /etc/init.d/bind9 script that incorrectly reports bind9 status. Opened up this file, I found:


Ah ha, the default location of named.pid is in /var/run/bind/run. In my case, named.pid is located in /var/chroot/var/run/bind/run/named.pid. Therefore in order to fix this, we just need to point PIDFILE to the correct file.


Save bind9 script, and check bind9 status again:

# /etc/init.d/bind9 status
bind9 is running.

Enable Japanese input on Debian/Ubuntu

Normally, I would install Scim and Anthy for Japanese input method on Debian. Recently, I found an easier way to achieve the same thing, which is to use IBus instead of Scim.

  1. Install ibus: sudo apt-get install ibus ibus-anthy ibus-gtk
  2. From the menu, System -> Preferences -> IBus Preference
    IBus Preference should detects that you have run IBus daemon yet, click “Yes” to run it.
  3. You’ll be asked to edit yoru .bashrc and add the following 3 lines:

    export GTK_IM_MODULE=ibus
    export XMODIFIERS=@im=ibus
    export QT_IM_MODULE=ibus
  4. Click on “Input Method” tab, if you don’t see “Japanese – Anthy” listed under the Input Method list, select “Japanese -> Anthy” from the “Select an input method” drop down list, then click Add.
  5. You might want to restart X (logout and log back in)
  6. Open a text editor, and hit Ctrl + Space to toggle the Japanese input method

Stopping hard drive clicking noise on MSI U100

Finally, the OS X has been removed from MSI Wind U100, and completely replaced by Debian (testing).

Whenever the computer is idle, the hdd makes this weird clicking noise. To stop it, we can use hdparm to turn it off.

kenno@tora:~$ sudo hdparm -B 254 /dev/sda

setting Advanced Power Management level to 0xfe (254)
APM_level = 254
