人種的測驗

http://www.mathsking.net/test/question.htm

You have 37 points. 你是第四種. 你是個充滿愛的人. 浪漫, 花和洒是你用來享受人生必要的東西. 你對承諾十分認真. 你是個很有家庭氣息的人, 你每個星期天都會打電話給你媽媽, 你永遠也不會忘記生日的日子. 不要讓你對浪漫的熱情與現實所發生的混淆一起.

変ですね！！！

夢をあきらめないで

夢をあきらめないで

詞、曲：岡村孝子

乾いた空に続く坂道
後姿が小さくなる
優しい言葉　探せないまま
冷えたその手を　振り続けた

いつかは　皆　旅立つ
それぞれの道を歩いていく

あなたの夢を　あきらめないで
熱く生きる瞳が好きだわ
負けないように　悔やまぬように
あなたらしく　輝いてね

苦しいことに　つまづく時も
きっと　上手に　越えて行ける
心配なんて　ずっと　しないで
似てる誰かを愛せるから

切なく残る痛みは
繰り返すたびに　薄れていく

あなたの夢を　あきらめないで
熱く生きる瞳が好きだわ
あなたが選ぶ全てのものを
遠くにいて信じている

あなたの夢を　あきらめないで
遠くにいて信じている

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
	


	
	
	

		
The source is now on Github: https://github.com/wanleung/self-signed-certificate-generator


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




Here is the file.
