ubuntu:

sudo apt-get install pptpd
//--------------------------------------------------------------------

$ sudo vi /etc/pptpd.conf

#把logwtmp註解掉
#logwtmp

#這兩行去掉註解
localip 192.168.0.1

$ sudo vi /etc/ppp/chap-secrets
#增加一個帳號密碼
# client    server  secret          IP addresses
user        pptpd   password        *

//----------------------------------

重新啟動pptpd
$ sudo /etc/init.d/pptpd restart
//--------------------------------
開啟 ipv4 forward
sudo vi /etc/sysctl.conf
#將以下值改為1
net.ipv4.ip_forward=1
使修改生效
$ sudo sysctl -p 

//---------------------------------

＊ 設定 iptables
#防火牆開這兩個：
iptables -A INPUT -p TCP -i $EXTIF --dport 1723 -j ACCEPT # vpn
iptables -A INPUT -p gre -i $EXTIF -j ACCEPT
#設定路由
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eth0 -j MASQUERADE
#eth0為對外連線的網卡介面
#若MSN或一些網站無法連，可能是MTU問題，加下面這行限制MTU大小

NX Client for Windows:
http://64.34.173.142/download/3.5.0/Windows/nxclient-3.5.0-9.exe

記得填
gnome-session --session=ubuntu-2d
或

sudo apt-get install xfce4

/usr/bin/startxfce4 

ubuntu 11.10開機進入文字畫面

sudo vi /etc/default/grub

把
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
改成：
GRUB_CMDLINE_LINUX_DEFAULT="text"
再執行sudo update-grub即可

如果是lightdm

sudo vi /etc/X11/default-display-manager
把
/usr/sbin/lightdb
改成
false

有

gdm的話：/user/sbin/gdm
lightdm：/user/sbin/lightdm
lxdm：/usr/sbin/lxdm



要進入X用
sudo start gdm
或
startx

記得在
~/.profile加上

export LANGUAGE="en_US.UTF-8"

export LANG="en_US.UTF-8"

避免中文亂碼

Xen

建立硬碟 (20000M=20G)

dd if=/dev/zero of=xen.img bs=1M count=20000

設定檔
注意boot = "c"是硬碟開機 boot = "d" 是光碟開機
vif中bridge=virbr0,script=vif-bridge"為橋接
vif = [ "ip=192.168.1.100, bridge=virbr0, script=vif-bridge" ]
如果要NAT的話
vif = ['ip=10.0.0.1' , script='vif-nat']

每台虛擬機要配不同port號(5900+N)
vncdisplay =要配的號碼
或者用自動找可用的port分配
vncunused = 1

不限定連進IP
vnclisten = "0.0.0.0"
限定本機
vnclisten = "127.0.0.1"

看開啟的Dom-U
sudo xm list

啟動Dom-U(對設定檔檔名)
sudo xm create neo.cfg

關閉Dom-U(對設定檔裡的name)
sudo xm shutdown neo


 brctl show

/sbin/ip a | grep '^[0-9]'

 vif0.0 綁到 virbr0 ：
brctl addif virbr0 vif0.0

建立bridge
brctl addbr xenvbr11
brctl stp xenvbr11 off
brctl setfd xenvbr11 0 //set forward delay time
ip link set xenvbr11 up
建vlan(區隔區網)
vconfig set_name_type DEV_PLUS_VID_NO_PAD
vconfig add peth0 11 //在peth0上创建vlan
ip link set peth0.11  address fe:ff:ff:ff:ff:ff
ip link set peth0.11 up





把vlan加入到网桥中
brctl addif xenvbr11 peth0.11
创建端口配置文件
cd /etc/sysconfig/network-scripts/
