Xen 3.0.3 on Debian 4.0 Etch

Here is the instruction for running XEN on Debian Etch on Core2Duo 6300 with 2GB Ram.

First, install all the packages that related to XEN.

apt-get install  libc6-xen linux-headers-2.6-xen-686
linux-headers-2.6-xen-vserver-686 linux-headers-2.6.18-4-xen
linux-headers-2.6.18-4-xen-686 linux-headers-2.6.18-4-xen-vserver
linux-headers-2.6.18-4-xen-vserver-686 linux-image-2.6-xen-686
linux-image-2.6-xen-vserver-686 linux-image-2.6.18-4-xen-686
linux-image-2.6.18-4-xen-vserver-686 linux-image-xen-686
linux-image-xen-vserver-686 linux-modules-2.6.18-4-xen-686
linux-modules-2.6.18-4-xen-vserver-686 xen-hypervisor-3.0.3-1-i386
xen-hypervisor-3.0.3-1-i386-pae xen-ioemu-3.0.3-1 xen-tools
xen-utils-3.0.3-1 xen-utils-common bridge-utils iproute sysfsutils

Then, boot reboot the machine and choose the pae kernel to boot.

Next, add the following into /etc/network/interface for the Xen Bridge neteork.

auto xenbr0
iface xenbr0 inet dhcp
bridge_ports eth0
# optional
bridge_maxwait 0

To build a new debian domain:

Configurature /etc/xen-tools/xen-tools.conf collectly such as kernel version and initrd.

Then, run

xen-create-image --hostname=<name_of_DomU> --dir /home/xen/images/debian

Next, configurature

/etc/xen/<name_of_DomU>.cfg

to make sure all the Tag are correct.

Finally, run

xm create test.cfg -c

to run the VM.

As Core2Duo 6300 support VT, we could run Windows under Xen.

To run Windows in Xen,

first, build an image file for windows.

dd if=/dev/zero of=/home/xen/images/WinXP.img bs=1M count=4096

Next, copy the Windows XP install CD in to an iso format

dd if=/dev/cdrom of=/home/xen/cds/winxp.iso

Then, build a winxp config file in /etc/xen as the following. eg:

vi /etc/xen/winxp

kernel = "hvmloader"
builder='hvm'
memory = 512
name = "winxp"
vif = [ 'type=ioemu, bridge=xenbr0' ]
disk = [ 'file:/home/xen/images/WinXP.img,ioemu:hda,w',
'file:/home/xen/cds/winxp.iso,hdc:cdrom,r' ]
#cdrom = '/dev/hda'
device_model = 'qemu-dm'
boot="dc"
sdl=1
vnc=0
nographic=0
localtime=1

Run

xm create winxp -c

to boot up the VM and install XP.

After finished installing the XP, turn off the VM and

change the

boot="dc"

to

boot="c"

in

/etc/xen/winxp

How to generate a self-signed certificate for apache2 in Debian

While the Debian apache2 package was in Apache version 2.0, there was a tool called "apache2-ssl-certificate" for the users to use that script to gererate their own self-signed cert themselves. However, the script was removed since the apache2 package had been upgraded to Apache v2.2.

I had modified the old script so that it can generate a suitable self-signed cert for the new apache2(Apache v2.2) in Debain.

Here is the code:

#!/bin/sh -e

DAYS="365"
CERTPATH="/etc/apache2/ssl"
CERTNAME="apache"
KEYBIT="1024"
FORCE="0";

usage(){
    echo "This is a program for the users to gernate their own self-signed certificate."
    echo
    echo "Usage:  $0 [[OPTION] [VALUE]]..."
    echo
    echo "OPTIONS:"
    echo "  -h | -help | --help -- To Show This Help"
    echo "  -f | --force        -- Force to generate the cert"
    echo "  -d | -days | --days -- cert to expire after x days, default is 365"
    echo "  -p | -path | --path -- Path of the cert will be stored,"
    echo "                         default is /etc/apache/ssl"
    echo "  -n | -name | --name -- the name of the cert, default is apache"
    echo "  -b | -bit  | --bit  -- length of the key, default is 1024"
    echo
}

createcert() {
    if [ "$FORCE" != "1" -a -f $CERTPATH/$CERTNAME.pem ]; then
        echo "$CERTPATH/$CERTNAME.pem exists!  Use \"$0 --force.\""
        exit 0
    fi
    echo
    echo creating selfsigned certificate
    echo "replace it with one signed by a certification authority (CA)"
    echo
    echo enter your ServerName at the Common Name prompt
    echo
    echo If you want your certificate to expire after x days call this programm
    echo with "--days x"

    mkdir -p "$CERTPATH/"

    export RANDFILE=/dev/random
    openssl req $@ -new -x509 -days $DAYS -nodes
    -newkey rsa:$KEYBIT
    -out $CERTPATH/$CERTNAME.pem
    -keyout $CERTPATH/$CERTNAME.pem
    chmod 600 $CERTPATH/$CERTNAME.pem
}

case $1 in
    -h|help|--help)
        usage
        exit 0
    ;;
esac

until [ -z "$1" ]  # Until all parameters used up . . .
do
    case $1 in
        --force|-f|-force)
	    FORCE="1"
	    shift
        ;;
	--days|-d|-days)
	    DAYS=$2
	    shift
	    shift
	;;
	--path|-p|-path)
	    CERTPATH=$2
	    shift
	    shift
	;;
	--name|-n|-name)
	    CERTNAME=$2
	    shift
	    shift
	;;
	--bit|-n|-bit)
	    KEYBIT=$2
	    shift
	    shift
	;;
	*)
	    usage
	    exit 0
	;;
    esac
done
createcert

Debian GNU/Linux 4.0 released

Debian Etch finally released on 8th April, 2007.
Here is the notice from debian-announce@lists.debian.org.

Debian GNU/Linux 4.0 released

The Debian Project is pleased to announce the official release of Debian
GNU/Linux version 4.0, codenamed "etch", after 21 months of constant
development.  Debian GNU/Linux is a free operating system which supports
a total of eleven processor architectures and includes the KDE, GNOME
and Xfce desktop environments.  It also features cryptographic software
and compatibility with the FHS v2.3 and software developed for version
3.1 of the LSB.

Using a now fully integrated installation process, Debian GNU/Linux 4.0
comes with out-of-the-box support for encrypted partitions.  This
release introduces a newly developed graphical frontend to the
installation system supporting scripts using composed characters and
complex languages; the installation system for Debian GNU/Linux has now
been translated to 58 languages.

Also beginning with Debian GNU/Linux 4.0, the package management system
has been improved regarding security and efficiency.  Secure APT allows
the verification of the integrity of packages downloaded from a mirror.
Updated package indices won't be downloaded in their entirety, but
instead patched with smaller files containing only differences from
earlier versions.

Debian GNU/Linux runs on computers ranging from palmtops and handheld
systems to supercomputers, and on nearly everything in between.  A total
of eleven architectures are supported including:  Sun SPARC (sparc), HP
Alpha (alpha), Motorola/IBM PowerPC (powerpc), Intel IA-32 (i386) and
IA-64 (ia64), HP PA-RISC (hppa), MIPS (mips, mipsel), ARM (arm), IBM
S/390 (s390) and -- newly introduced with Debian GNU/Linux 4.0 -- AMD64
and Intel EM64T (amd64).

Debian GNU/Linux can be installed from various installation media such
as DVDs, CDs, USB sticks and floppies, or from the network.  GNOME is
the default desktop environment and is contained on the first CD.  The K
Desktop Environment (KDE) and the Xfce desktop can be installed through
two new alternative CD images.  Also newly available with Debian
GNU/Linux 4.0 are multi-arch CDs and DVDs supporting installation of
multiple architectures from a single disc.

Debian GNU/Linux can be downloaded right now via bittorent (the
recommended way), jigdo or HTTP;  see <http://www.debian.org/CD/> for
further information.  It will soon be available on DVD and CD-ROM from
numerous vendors <http://www.debian.org/CD/vendors/>, too.

This release includes a number of updated software packages, such as the
K Desktop Environment 3.5 (KDE), an updated version of the GNOME desktop
environment 2.14, the Xfce 4.4 desktop environment, the GNUstep desktop
5.2, X.Org 7.1, OpenOffice.org 2.0.4a, GIMP 2.2.13, Iceweasel (an
unbranded version of Mozilla Firefox 2.0.0.3), Icedove (an unbranded
version of Mozilla Thunderbird 1.5), Iceape (an unbranded version of
Mozilla Seamonkey 1.0.8), PostgreSQL 8.1.8, MySQL 5.0.32, GNU Compiler
Collection 4.1.1, Linux kernel version 2.6.18, Apache 2.2.3, Samba
3.0.24, Python 2.4.4 and 2.5, Perl 5.8.8, PHP 4.4.4 and 5.2.0, Asterisk
1.2.13, and more than 18,000 other ready to use software packages.

Upgrades to Debian GNU/Linux 4.0 from the previous release, Debian
GNU/Linux 3.1 codenamed "sarge", are automatically handled by the
aptitude package management tool for most configurations, and to a
certain degree also by the apt-get package management tool.  As always,
Debian GNU/Linux systems can be upgraded quite painlessly, in place,
without any forced downtime, but it is strongly recommended to read the
release notes for possible issues.  For detailed instructions about
installing and upgrading Debian GNU/Linux, please see the release notes
<http://www.debian.org/releases/etch/releasenotes>.  Please note that
the release notes will be further improved and translated to additional
languages in the coming weeks.

うれしい時には　君が笑ってて
悲しいときいつでも　僕がそばにいて

沢山の経験　重ねていく度
理想と現実との　距離が近付く

いつか君は　教えてくれた
思いやりと　涙のわけを

振り向けば君はそこにいて
受けとめてくれた
今度は誰かに
この気持ちかえそう
何もできないなんて言わない
何か出来ること
ひとつでもいいから
手をのばすんだ
届く日まで



悩んでる君に　何が出来るだろう
立ち尽くしてしまうよ　言葉届かずに

信じているけど　とても苦しくて
希望と絶望とが　交差している

君自身が　君の力で
歩けるまで　待っていなくちゃ

素直とわがままは全然　違うものなのに
なぜだろう時々　わからなくなるんだ
抱きしめたい気持ち押さえて
黙って見ている　切ない勇気で
少しでもいい　近付きたい


振り向けば君はそこにいて
受けとめてくれた
今度は誰かに
この気持ちかえそう
何もできないなんて言わない
何か出来ること
ひとつでもいいから
手をのばすんだ
届く日まで

MAKING LOVE OUT OF NOTHING AT ALL

MAKING LOVE OUT OF NOTHING AT ALL (Air Supply)

I know just how to whisper
And I know just how to cry
I know just where I find the answers
And I know just how to lie
I know just how to fake it
And I know just how to scheme
I know just when to face the truth
And then I know just when to dream
And I know just where I touch you
And I know just what to prove
I know when to pull you closer
And I know when to let you loose

And I know the night is fading
And I know the time’s gonna fly
And I’m never gonna tell you everything I gotta tell you
But I know I’ve got to give it a try

And I know the roads to riches
And I know the ways to pain
I know all the rules and then I know how to break’em
And then I always know the name of the game

But I don’t know how to leave you
And I’ll never let you fall
And I don’t know how you do it
Making love out of nothing at all

Making love
Out of nothing at all
Making love
Out of nothing at all
Making love
Out of nothing at all
Making love
Out of nothing at all
Making love
Out of nothing at all
Making love
Out of nothing at all

Everytime I see you, well the rays of the sun are all
Streaming through the waves in your hair
And every star in the sky is taking aim at your eyes
Like a spotlight
The beating of my heart is a drum and it’s lost
And it’s looking for a rhythm like you
You can take the darkness from the deep of the night
And turn it to a beacon burning endlessly bright
I gotta follow it ‘cause everything I know
Well, it’s nothing ‘till I give it to you

I can make the runner stumble
I can make the final block
And I can make every tackle at the sound of the whistle
And I can make all the stadiums rock

I can make tonight forever
Or I can make it disappear by the dawn
And I can make you every promise that’s ever been made
And I can make all your demons be gone

But I’m never gonna make it without you
Do you really wanna see me crawl ?
And I’m never gonna make it like you do
Making love out of nothing at all

Making love
Out of nothing at all...

卒業 Next Graduation

已經有好幾年停了玩純愛系列的GAME，

最近在GAME舖看到這隻，



卒業 Next Graduation，就買了回來。

卒業，相信各位對這GAME並不陌生，

卒業可以說是在PC上最早期的純愛GAME之一，

1992年6月在日本發售，之後翻譯成中文版，

相信各位在DOS年代應曾努力過去執行這GAME，

因為這GAME需要580K以上的MEMORY才能執行，

當年DOS上限是640K，玩這GAME前，要花不少功夫改CONFIG，

不過本人是沒成功執行過卒業這GAME就是了。

對卒業的認識，是看動畫吧了。

卒業其後亦出過2代3代等的延續，不過由於太早期關係（94年及98年），

亦沒有玩過其後的作品。

（本人正式開始玩純愛GAME是1999年會考後，第一隻是初戀，第二隻是青澀之戀，第三隻才是心跳回憶，其後亦開始迷上了動畫。）

卒業 Next Graduation，這隻是最新作，

主人公已由第一代的新入行教師，成為這代的校長，

而今次5位問題學生女主角，正是一代那5位主角的女兒，

果然10年人事幾番新，

不經不覺卒業已有10幾年的歷史。

卒業 Next Graduation這GAME，對本人最大吸引在於配音，

女主角的母親，由卒業動畫版原班人馬配音，

分別是鶴ひろみ，島方淳子，芳野日向子，冬馬由美 及 久川綾。

由於本人是比較算是ACG早期的人，

因此只對一些舊的配音員比較熟識，

新角色，除了配助手的滿仲由紀子（青澀之戀中的夏穗）是所認知之外，

其他的配音都是本人所不認知的。

絕望真相

剛問同事借了戈爾的＜絕望真相＞回來看，發覺地球溫室效應加劇，令地球氣候環境改變的情況，比自己原本所認知的嚴重，而且若我們還在坐視不理的話，地球很有可能會在我們這一兩代變成不適合人類居住。

地球只有一個，是我們在這宇宙中唯一的家，
地球會否毀在我們手上，就要看我們現在決定。

求今天所得　永遠守

命運是對手永不低頭
從來沒抱怨半句　不去問理由
仍踏著前路走青春走到白頭
成功只有靠一雙手

水調歌頭 蘇軾

明月幾時有，把酒問青天。

不知天上宮闕，今夕是何年。

我欲乘風歸去，又恐瓊樓玉宇，高處不勝寒。

起舞弄清影，何似在人間。

轉朱閣，低綺戶，照無眠。

不應有恨，何事長向別時圓。

人有悲歡離合，月有陰晴圓缺，此事古難全。

但願人長久，千里共嬋娟。

A Life Among Whales

今晚National Geographic Channel做了2套有關鯨魚的記錄片，

內容值得我們反思。

第一個節目是談到Dr Roger Payne研究鯨魚時的發現，他的研究令世界對鯨魚的看法改變，以及世界對保護鯨魚的努力。另亦提及國際捕鯨協會（International Whaling Commission）在80年代禁止商業捕鯨，各捕鯨國，如丹麥，日本等國，如何用“科學”一詞來繼續無視地繼續捕鯨，以及對國際捕鯨協會（International Whaling Commission）在商討恢復商業捕鯨的無奈。

鯨魚的腦比人類大，而且皮層亦比人類厚，以現在生物學的觀念，是比人類聰明，
但科學家到現時，對鯨魚的智力仍所知甚少。Dr Roger Payne在研究座頭鯨時，發現鯨魚發出的聲音，
以人類的定義，那些聲音叫旋律，以15分鐘為一週期，不斷重複，而且旋律會押韻。
因此推斷，鯨類的智力，至少和人類不相上下。

節目中，Dr Roger Payne有2句話，非常發人深醒，
大意是“若我們連這些大型鯨類，我們有能力保護但都保護不了，我們憑什麼可保護自己”，
“不要以為自己一個就做不了什麼，要改變現在，正是要由自己做起”。

保護環境，救救地球。
