If you have DNS server running, make sure you remove the following lines from /etc/hosts:

127.0.0.1 nasbox localhost
::1 nasbox localhost ip6-localhost ip6-loopback

However, if you don’t have DNS server running to manage your domain then you need to explicitly assign the IP address to the domain. Adjust the IP address and hostname to your environment:

#192.168.1.123 nasbox.myserver.com nasbox

In my case, I could successfully start nfs-kernel-server:

# /etc/init.d/nfs-kernel-server start

$ file adb
adb: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.8, stripped

After googling around, the fix is quite simple: re-install ‘libc6-i386′.

$ sudo apt-get install --reinstall libc6-i386
$ ./adb

Change fonts in ~/.gitk to DejaVu Sans Mono.

set mainfont {{DejaVu Sans Mono} 9}
set textfont {{DejaVu Sans Mono} 9}
set uifont {{DejaVu Sans Mono} 9 bold}

I assume you have ‘adb’ working. We are going to replace only 2 fonts – Arial.ttf and Arial-Bold.ttf.

First, let’s back up the old fonts just in case thing didn’t go well as we want to. (I learned this the hard way, and keen to avoid it at all cost)

$ adb pull /system/fonts/Arial.ttf
$ adb pull /system/fonts/Arial-Bold.ttf

You should have a copy of the above 2 fonts on your local computer. Next is to connect to your phone and replace those fonts with DroidSans.ttf and DroidSans-Bold.ttf respectively.

$ adb shell
# cd /system/fonts
# cp DroidSans.ttf Arial.ttf
# cp DroidSans-Bold.ttf Arial-Bold.ttf

Restart your phone. Voila, your text doesn’t look as ugly as before; well at least that’s what I think.

# /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:

...
PIDFILE=/var/run/bind/run/named.pid
...

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.

PIDFILE=/var/chroot/var/run/bind/run/named.pid

Save bind9 script, and check bind9 status again:

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


Usually it works quite well, but not today (and probably some more days to come), it gave me a HTTP ERROR 404.  I thought I should just visit http://three.net.au and find out w-t-h is wrong. Unexpectedly it took me to another site — “callenden group policy wording”. It’s very weird so with some spare time, I decided to do a little investigation.

First let’s check who owns three.net.au:

Now let’s find out the IP address of three.net.au:

According to the query result, three.net.au points to this IP address: 202.139.248.52.
192.168.1.132 is my own DNS server, therefore it may have cached the results. Let’s try to dig against the domain’s DNS servers instead.


$ dig @202.181.231.99 three.net.au

We still get the same result. I did also dig against 202.181.231.99 and 202.181.231.100 which yield the same results.

Now let’s do a reverse lookup of 202.139.248.52.

$ dig -x 202.139.248.52

52.248.139.202.in-addr.arpa. 116 IN PTR www.policywording.com.au.

This explains why visiting three.net.au shows you the webpage of www.policywording.com.au.

My bet is that someone who looks after the DNS of three.net.au domain must have entered the wrong IP address for three.net.au. If I have a bit of free time, I’ll give ’3′ customer service a call and get them fix this annoying error.
