早上来上班，装了一个主题，�l�果让我explorer.exe无法正常��h��Q�桌面看不到�Q�只能用��d��理器来做一些事情�?br /> 解决�Ҏ��Q?下蝲了新的explorer.exe�Q�覆盖，搞定。费��！
———————————————————————�?br />

Rundll32.exe, ��֐�思义�Q�“执�?2位的DLL文�g”。它的作用是执行DLL文�g中的内部函数�Q�这样在�q�程当中�Q�只会有Rundll32.exe�Q�而不会有DLL后门的进�E�，�q�样�Q�就实现了进�E�上的隐藏。如果看到系�l�中有多个Rundll32.exe�Q�不必惊慌，�q�证明用Rundll32.exe启动了多��个的DLL文�g。当�Ӟ��q�些Rundll32.exe执行的DLL文�g是什么，我们都可以从�pȝ��自动加蝲的地�Ҏ��到�?

Rundll32.exe使用的函数原型：
Void CALLBACK FunctionName (
HWND hwnd,
HINSTANCE hinst,
LPTSTR lpCmdLine,
Int nCmdShow
);

其命令行下的使用�Ҏ��为：Rundll32.exe DLLname,Functionname [Arguments]
DLLname为需要执行的DLL文�g名；Functionname为前辚w��要执行的DLL文�g的具体引出函敎ͼ�[Arguments]为引出函数的具体参数�?

利用rundll32重启机器的实�?: 点击“开始－�E�式�Q�Ms�Q�Dos方式”，�q�入Dos视窗�Q�然后键入rundll32.exe user.exe,restartwindows�Q�再按下回�R键，�q�时你将看到�Q�机器被重启了！

RUNDLL.EXE
�q�里要注意三点：1.Dll档案名中不能含有�I�格�Q�比如该档案位於c:\ProgramFiles\目录�Q�你要把�q�个路径�Ҏ��c:\Progra�?\�Q?.Dll档案名与Dll入口炚w��的逗号不能��，否则�E�式��出错�ƈ且不会给��Z�Q何资讯！3.�q�是最重要的一点：Rundll不能用来呼叫含返回值参数的Dll�Q�例如Win32API中的GetUserName(),GetTextFace()�{�。在Visual Basic中，提供了一条执行外部程式的指��oShell,格式为：
Shell “命令列�?
如果能配合Rundll32.exe用好Shell指��o�Q�会使您的VB�E�式拥有用其他方法难以甚��x��法实现的效果�Q�仍以重启�ؓ例，传统的方法需要你在VB工程中先建立一个模�l�，然后写入WinAPI的声明，最后才能在�E�式中呼叫。而现在只需一�?

Shell “rundll32.exe user.exe,restartwindows”就搞定了！

# Please see vsftpd.conf.5 for all compiled in defaults.
#

# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=yes

# Uncomment this to allow local users to log in.
local_enable=YES
#local_root=/var/ftp
#
# Uncomment this to enable any form of FTP write command.

# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
local_umask=022
#user_config_dir=/etc/vsftpd/userconf
#
# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will

# recommended for security (the code is non-trivial). Not enabling it,
however, may confuse older FTP clients.

# By default the server will pretend to allow ASCII mode but in fact ignore
# the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode.
# Beware that turning on ascii_download_enable enables malicious remote parties
# to consume your I/O resources, by issuing the command "SIZE /big/file" in
# ASCII mode.
# These ASCII options are split into upload and download because you may wish

#
# You may activate the "-R" option to the builtin ls. This is disabled by

VNC�q�程控制LINUX 之一

Kimi — Fri, 31 Mar 2006 03:55:00 GMT

[b]什么是VNC?[/b]

VNC是虚拟网�l�计��Virtual Network Computing的羃�? 他是一个远�E�控制程�?允许用户在因特网的�Q何地方��用简单的�E�序来和一个特定的

计算�?服务�?�q�行交互. 两个交互的计��机不一定非得是同一�c�d��,所以你可以在家里的�q�行windows的PC上来察看办公室里�q�行LINUX的机�?br />
。VNC可以自由获取�q�且有上百万的�h在��用，他们来自工业、学术和个�h应用�{�不同层�?

更多的信息请讉K�� [url]http://www.realvnc.com/[/url]

[b]我的�pȝ��中已�l�有�q�个软�g了吗�Q�[/b]

键入下面的命令来��查vnc客户端和服务器是否已�l�安装在你的�pȝ��中：

[tchung@tchung101 tchung]$ rpm -q vnc vnc-server
vnc-4.0-0.beta4.3.2
vnc-server-4.0-0.beta4.3.2
[tchung@tchung101 tchung]$

要把vnc配置成一��系�l�服务，把你的用户名�U�加入到下面的配�|�文件中�Q?br />
[code][tchung@tchung101 tchung]$ sudo vi /etc/sysconfig/vncservers

# The VNCSERVERS variable is a list of display:user pairs.
#
# Uncomment the line below to start a VNC server on display :1
# as my 'myusername' (adjust this to your own).  You will also
# need to set a VNC password; run 'man vncpasswd' to see how
# to do that.
#
# DO NOT RUN THIS SERVICE if your local area network is
# untrusted!  For a secure way of using VNC, see
# URL:http://www.uk.research.att.com/vnc/sshvnc.html

# VNCSERVERS="1:myusername"
VNCSERVERS="1:tchung"[/code]
在启动vnc服务之前�Q�让我们用vncpasswd�q�个命��o来创��Z��个vnc的口�?br />
注意�q�将同时在你的home目录下，创徏一个隐藏的目录.vnc�Q�其中有一个文件passwd保存着你的vnc口��o.

[code][tchung@tchung101 tchung]$ vncpasswd
Password:
Verify:
[tchung@tchung101 tchung]$ ls -d .vnc
.vnc
[tchung@tchung101 tchung]$ ls .vnc
passwd
[tchung@tchung101 tchung]$[/code]

现在来启动vnc服务.

[code][tchung@tchung101 tchung]$ sudo /sbin/service vncserver start
Starting VNC server: 1:tchung                            [  OK  ]
[tchung@tchung101 tchung]$[/code]

察看一�?vnc�q�个目录的内容，应该�c�M��于下面的东西.

[code][tchung@tchung101 tchung]$ cd .vnc
[tchung@tchung101 .vnc]$ ls
passwd  tchung101:1.log  tchung101:1.pid  xstartup
[tchung@tchung101 .vnc]$[/code]

�~�辑�q�个名�ؓxstartup的脚本，注意��C��面红色的部分的注�?br />��这两行标记成[color=red]�U�色[/color]的内容前面的注释�W�号��L��Q�否则你��只能得��C��个什么都没有的灰屏�?!/bin/sh

# Uncomment the following two lines for normal desktop:

[color=red]unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc[/color]


[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &

因�ؓ我们已经修改了启动脚本，现在来重新启动vncserver.

[code][tchung@tchung101 tchung]$ sudo /sbin/service vncserver restart
Shutting down VNC server: 1:tchung                      [  OK  ]
Starting VNC server: 1:tchung                            [  OK  ]
[tchung@tchung101 tchung]$[/code]

那么怎样来连接到vncserver? 照下面��用客��L��的vncviewer命��o.

[tchung@tchung101 tchung]$ vncviewer localhost:1

输入你的vnc口��o�Q�看一下结�?br />
更新:
在��用防火墙的情况下来连接到一个远�E�系�l?需要打开端口5901.
加入以下�U�色的部分，然后重启iptables服务�?br />
[tchung@tchung101 tchung]$ sudo vi /etc/sysconfig/iptables

# Firewall configuration written by redhat-config-securitylevel
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0]
:FORWARD ACCEPT [0]

[color=red]-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPT[/color]
-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
COMMIT

[tchung@tchung101 tchung]$ sudo /sbin/service iptables restart
Flushing firewall rules:                                  [  OK  ]
Setting chains to policy ACCEPT: filter                   [  OK  ]
Unloading iptables modules:                               [  OK  ]
Applying iptables firewall rules:                         [  OK  ]
[tchung@tchung101 tchung]$

Forrest Taylor 提供的TIP

让vncserver接受两个不同的用�?

[code] VNCSERVERS="1:tchung 2:thomasc"[/code]

当然你要��Z��个用户分别运行vncpasswd来设�|�口�? �q�且在你的防火墙修改中，你应该明白VNC使用端口5901�l�连�?用，如果象上面一栯��?br />
持两个用��P��应同时打开5901�?902.

一、引�a�
我们可以通过telnet、ssh�{�远�E�登录Linux服务器，但都是字�W�界面的。本文介�l�了通过XDMCP+XDM�?br />
�q�程�q�接Linux服务器上的XFree86 Server�Q�可以在囑�Ş环境下远�E�管理Linux服务器�?br />
二、基本概�?br />1、什么是XFree86
XFree86是X Window�pȝ��的一�U�开放源代码的实现。它提供了一�U�对鼠标、键盘、显卡和�H�口囑�Ş环境

的Client-Server接口。所以客��L��E�序可以�q�行在不同的��L��上，�׃��台服务器提供X Window的Server服务�?br />2、什么是XDMCP
XDMCP即“X Display Manager Control Protocol”，是一�U�网�l�协议。由它来建立囑�Ş客户端程�?br />
与X Window服务器的�q�接与通信�?br />3、什么是XDM
XDM即“X Display Manager”，由它来启动X Window服务器，�q�管理图形客��L��E�序的登录、会话�?br />
启动�H�口��理器（KDE、Gnome�Q�等。KDE和Gnome也提供了自己的xdm的实玎ͼ�分别叫kdm和gdm�?br />4、什么是XFS
XFS即“X Font Server”，可以��q��一台服务器来统一提供字体�Q�远�E�图形客��L��E�序��׃��需要单�?br />
安装所有的字体了�?br />
三、配�|�过�E?br />1、我们的环境
我们使用一台装有Mandrake Linux 8.1的计��机作�ؓX Window的服务器�Q�服务器上网卡地址

�?92.168.0.1/24。�ƈ且在安装Linux时一起安装了XFree86相关软�g包�?br />我们在局域网中的另一台装有Windows 2000的计��机上安装了X-Win32软�g�Q�作为X Window的客

��L��。还有很多Windows下的X客户端程序，但大多是商业�E�序�Q�如exceed只提�?0天的试用期�?br />
而X-Win32没有天数限制�Q�只是每�ơ只能��?0分钟�Q�这对于大多数基本的服务器维护操作也够了�Q?br />
旉��C��再连接就是了。免费��用商业程序不能要求太高了:-)

2、配�|�服务器
(1)配置xfs
xfs的配�|�文件是/etc/X11/fs/config�Q�内容如下：
#
# Default font server configuration file for Mandrake Linux workstation
#

# allow a max of 4 clients to connect to this font server
client-limit = 4

# when a font server reaches its limit, start up a new one
clone-self = off

# alternate font servers for clients to use
#alternate-servers = foo:7101,bar:7102

# where to look for fonts
# Some of these are commented out, i.e. the TrueType and Type1
# directories in /usr/share, because they arent forced to be
# installed alongside X.
#
catalogue = /usr/X11R6/lib/X11/fonts/misc:unscaled,
/usr/X11R6/lib/X11/fonts/75dpi:unscaled,
/usr/X11R6/lib/X11/fonts/100dpi:unscaled,
/usr/X11R6/lib/X11/fonts/misc:unscaled,
/usr/X11R6/lib/X11/fonts/Type1,
/usr/X11R6/lib/X11/fonts/Speedo,
/usr/X11R6/lib/X11/fonts/mdk:unscaled,
/usr/share/fonts/default/Type1,
/usr/share/fonts/ttf/big5,
/usr/share/fonts/ttf/gb2312,
/usr/share/fonts/ttf/decoratives,
/usr/share/fonts/ttf/western

# in 12 points, decipoints
default-point-size = 120

# 100 x 100 and 75 x 75
default-resolutions = 75,75,100,1
# how to log errors
use-syslog = on

在配�|�文件中可以定义最大客��L��q�接数量�Q�这里缺省是4。配�|�文件中也指明了字体文�g的位�|�，

特别注意包含了中文字体，否则在客��L��无法正确昄��中文字体�?br />接下来修�?etc/rc.d/init.d/xfs文�g�Q�把所有�?port -1”改为�?port 7100”，�q�是xfs�~�省�?br />
听的端口。��用如下命令来重启xfs�Q?br />service xfs stop
service xfs start
xfs启动成功后，可以使用netstat -ln命��o来确�?100端口已绑定：
tcp 0 0 0.0.0.0:7100 0.0.0.0:* LISTEN

(2)配置xdm
xdm的配�|�文件在/etc/X11/xdm目录下�?br />首先修改xdm-config文�g�Q�找��C��行：DisplayManager.requestPort: 0
注释�q�行�Q?DisplayManager.requestPort: 0
如果有这行，xdm��׃��会监听XDMCP的连接了�?br />接下来修改Xaccess文�g�Q�这是控制客��L��讉K��的配�|�文�Ӟ��修改内容如下�Q?br />#* #any host can get a login window(��L��前面�?�Q?br />现在可以直接使用xdm命��o来启动xdm服务�Q��用netstat -ln命��o来确�?77端口�Q�xdm�~�省的端口）
已绑定：
udp 0 0 0.0.0.0:177 0.0.0.0:*

/etc/X11/xdm/xdm-config:
!Display ManagerrequestPort=0(前面�Q�！�Q?br />
/etc/X11/xdm/Xaccess:
# * # any host can get a login window(��L��前面#�Q?br />

如果惌��在服务器启动后自动运行xdm�Q�就需要修�?etc/inittab文�g�Q��启动后进入�?”运行��别，

修改内容如下�Q?br />id:5:initdefault:
respawn:/etc/X11/profile �Ҏ�� respawn:/usr/bin/gdm

/etc/X11/gdm/gdm.conf
(xdmp)Enable=true
Port=177

我一般��用Xmanager�Q�觉的比较好
