Command line Programs and Functions


NetSH

Network shell netsh is a command-line utility that allows you to configure and display the status of various network communications server roles and components after they are installed on computers running Windows Server 2008 R2 and Windows Server 2008

Some client technologies, such as Network Access Protection (NAP) client and Dynamic Host Configuration Protocol (DHCP) client, also provide netsh commands that allow you to configure client computers running Windows® 7 and Windows Vista®.

In most cases, netsh commands provide the same functionality that is available when using the Microsoft Management Console (MMC) snap-in for each server role or component. For example, you can configure Network Policy Server (NPS) by using either the NPS MMC snap-in or the netsh commands in the netsh nps context.

In addition, there are netsh commands for network technologies, such as for IPv6, network bridge, and remote procedure call (RPC), that are not available in Windows as an MMC snap-in

[[..]] Parameters

/? Displays help at the command prompt. abort

Discards any changes made in offline mode. Abort has no effect in online mode.

Syntax

abort

Parameters

/? Displays help at the command prompt. add helper

Installs the helper dynamic-link library (DLL) in netsh. Syntax

add helper DLLName

Parameters

DLLName

Required. Specifies the name of the helper DLL that you want to install.

/?

alias

Adds an alias that consists of a user-defined character string, which netsh treats as equivalent to another character string. Used without parameters,alias displays all available aliases. Syntax

Parameters


alias[ AliasName]

Displays the specified alias.

alias[ AliasName][ String1[ String2...]]

Sets AliasName to the specified strings.

Displays help at the command prompt.

Examples

The following netsh sample script sets two netsh aliases, Shaddr and Shp, and then leaves the Netsh command prompt in the Interface IP context:

alias shaddr show interface ip addr

alias shp show helpers�interface ip

If you type shaddr at the Netsh command prompt, Netsh.exe interprets this as the command show interface ip addr. If you type shp at the Netsh command prompt, Netsh.exe interprets this as the command show helpers. bye

Exits Netsh.exe.

Syntax


bye

Parameters


/?

Displays help at the command prompt.

commit

Commits any changes made in the offline mode to the router. Commit has no effect in online mode. Syntax

DLLName

Required. Specifies the name of the helper DLL that you want to uninstall.

/?

Displays help at the command prompt.


dump

Creates a script that contains the current configuration. If you save this script to a file, you can use the file to restore configuration settings that have been changed. Used without parameters, dump displays all of the netsh context configurations. Syntax

dump [FileName]


Parameters

[ FileName]

Specifies the name of the file to which you want to redirect output.

/?

Displays help at the command prompt.

exec

{/? | ? | help | h}

Parameters

none

offline

Sets the current mode to offline.

Syntax

offline

Parameters

/? Displays help at the command prompt.

Remarks

Changes that you make in this mode are saved, but you must run the commit or online command to set the changes in the router.

When you switch from offline mode to online mode, changes that you made in offline mode are reflected in the configuration that is currently running.

Changes that you make in online mode are immediately reflected in the configuration that is currently running.

online

Sets the current mode to online.

Syntax

online

Parameters

/? Displays help at the command prompt.

Remarks

Changes that you make in online mode are immediately reflected in the configuration that is currently running. When you switch from offline mode to online mode, changes that you made in offline mode are reflected in the configuration that is currently running.

popd

Restores a context from the stack.

Syntax

popd

Parameters

/?

Displays help at the command prompt.

Remarks

Used in conjunction with pushd, popd enables you to change the context, run the command in the new context, and then resume the prior context.

Examples

The following sample script changes a context from the root context to the interface ip context, adds a static IP route, and then returns to the root context:

netsh>pushd

netsh>interface ip

netsh interface ip>set address local static 10.0.0.9 255.0.0.0 10.0.0.1 1

netsh interface ip>popd

netsh>

pushd

Saves the current context on a first-in-last-out (FILO) stack.

Syntax

pushd

Parameters

/?

Displays help at the command prompt.

Remarks

Used in conjunction with popd, pushd enables you to change the context, run the command in the new context, and then resume the prior context.

quit

Exits Netsh.exe.

Syntax

quit

Parameters

/?

Displays help at the command prompt.

set file

Copies the command prompt window output to a file.

Syntax

set file [ mode= ]{openFileName | appendFileName | close}

Parameters

openFileName

Sends the command prompt window output to the specified new file.

appendFileName

Appends the command prompt window output to the specified existing file.

close

Stops sending output and closes a file.

/? Displays help at the command prompt.

If the specified FileName does not currently exist, netsh creates a new file with that name. If the specified FileName does currently exist, netshoverwrites the existing data.

Examples

To create a new log file called Session.log and copy all succeeding netsh input and output to Session.log, type:

set file open c:\session.log

You can then use set machine again in the same script to specify another destination computer (Computer B), and then any additional commands you add to the script will run on Computer B.
