实验一

实验一 WINDOWS中的进程

一、目的:

1、了解在WINDOWS的系统进程,了解WINDOWS中进程的控制。

2、了解在WINDOWS中程序的运行原理,特别是自动运行的程序的运行机制。

二、内容:

1、写出本机中的进程。

2、了解以下进程的作用

System Idle Process

System

Smss.exe

Csrss.exe

Services.exe

Lsass.exe

Svchost.exe

Winlogon.exe

3、利用NTSD命令结束以下进程,并记录结束后的系统出现的现象。

Lsass.exe

Scrss.exe

4、了解在WINDOWS中有哪些位置可以在系统启动后自动建立进程,即在WINDOWS 中可自动运行的位置有哪些。

三、实验要求:

可以上网查询。

四、实验说明:

1、NTSD的帮助

usage: ntsd [-?] [-2] [-d] [-g] [-G] [-myob] [-lines] [-n] [-o] [-s] [-v] [-w]

[-r BreakErrorLevel] [-t PrintErrorLevel]

[-hd] [-pd] [-pe] [-pt #] [-pv] [-x | -x{e|d|n|i} ]

[-- | -p pid | -pn name | command-line | -z CrashDmpFile]

[-zp CrashPageFile] [-premote transport] [-robp]

[-aDllName] [-c "command"] [-i ImagePath] [-y SymbolsPath]

[-clines #] [-srcpath SourcePath] [-QR \\machine] [-wake ] [-remote transport:server=name,portid] [-server transport:portid]

[-ses] [-sfce] [-sicv] [-snul] [-noio] [-failinc] [-noshell]

where: -? displays this help text

command-line is the command to run under the debugger

-- is the same as -G -g -o -p -1 -d -pd

-aDllName sets the default extension DLL

-c executes the following debugger command

-clines number of lines of output history retrieved by a remote client

-failinc causes incomplete symbol and module loads to fail

-d sends all debugger output to kernel debugger via DbgPrint

-d cannot be used with debugger remoting

-d can only be used when the kernel debugger is enabled

-g ignores initial breakpoint in debuggee

-G ignores final breakpoint at process termination

-hd specifies that the debug heap should not be used

for created processes. This only works on Windows Whistler. -o debugs all processes launched by debuggee

-p pid specifies the decimal process Id to attach to

-pd specifies that the debugger should automatically detach

-pe specifies that any attach should be to an existing debug port

-pn name specifies the name of the process to attach to

-pt # specifies the interrupt timeout

-pv specifies that any attach should be noninvasive

-r specifies the (0-3) error level to break on (SeeSetErrorLevel) -robp allows breakpoints to be set in read-only memory

-t specifies the (0-3) error level to display (SeeSetErrorLevel) -w specifies to debug 16 bit applications in a separate VDM

-x sets second-chance break on A V exceptions

-x{e|d|n|i} sets the break status for the specified event

-2 creates a separate console window for debuggee

-i ImagePath specifies the location of the executables that generated

the fault (see _NT_EXECUTABLE_IMAGE_PATH)

-lines requests that line number information be used if present

-myob ignores version mismatches in DBGHELP.DLL

-n enables verbose output from symbol handler

-noio disables all I/O for dedicated remoting servers

-noshell disables the .shell (!!) command

-QR <\\machine> queries for remote servers

-s disables lazy symbol loading

-ses enables strict symbol loading

-sfce fails critical errors encountered during file searching

-sicv ignores the CV record when symbol loading

-snul disables automatic symbol loading for unqualified names

-srcpath specifies the source search path

-v enables verbose output from debugger

-wake wakes up a sleeping debugger and exits

-y specifies the symbol search path (see _NT_SYMBOL_PATH) -z specifies the name of a crash dump file to debug

-zp specifies the name of a page.dmp file

to use with a crash dump

-remote lets you connect to a debugger session started with -server

must be the first argument if present

transport: tcp | npipe | ssl | spipe | 1394 | com

name: machine name on which the debug server was created portid: id of the port the debugger server was created on

for tcp use: port=

for npipe use: pipe=

for 1394 use: channel=

for com use: port=,baud=,

channel=

for ssl and spipe see the documentation

example: ... -remote npipe:server=yourmachine,pipe=foobar -server creates a debugger session other people can connect to

must be the first argument if present

transport: tcp | npipe | ssl | spipe | 1394 | com

portid: id of the port remote users can connect to

for tcp use: port=

for npipe use: pipe=

for 1394 use: channel=

for com use: port=,baud=,

channel=

for ssl and spipe see the documentation

example: ... -server npipe:pipe=foobar

-premote transport specifies the process server to connect to

transport arguments are given as with remoting Environment Variables:

_NT_SYMBOL_PATH=[Drive:][Path]

Specify symbol image path.

_NT_ALT_SYMBOL_PATH=[Drive:][Path]

Specify an alternate symbol image path.

_NT_DEBUGGER_EXTENSION_PATH=[Drive:][Path]

Specify a path which should be searched first for extensions dlls

_NT_EXECUTABLE_IMAGE_PATH=[Drive:][Path]

Specify executable image path.

_NT_SOURCE_PATH=[Drive:][Path]

Specify source file path.

_NT_DEBUG_LOG_FILE_OPEN=filename

If specified, all output will be written to this file from offset 0.

_NT_DEBUG_LOG_FILE_APPEND=filename

If specified, all output will be APPENDed to this file.

_NT_DEBUG_HISTORY_SIZE=size

Specifies the size of a server's output history in kilobytes Control Keys:

Quit debugger

Break into Target

Force a break into debuggee (same as Ctrl-C)

Debug Current debugger

Toggle Verbose mode

Print version information
