Netsh Commands for Peer-to-Peer Networking (P2P)

  • Article

Applies To: Windows Server 2008

Peer-to-peer (P2P) technologies are used to facilitate real-time communication and collaboration across distributed networks. In the peer-to-peer model, without using Internet servers, each computer user can do the following:

  • Exchange data

  • Share resources

  • Locate other users

  • Communicate

  • Collaborate directly in real time

By using peer-to-peer technologies, applications that coordinate the use of computer CPU cycles and storage can share resources among large or small groups of computers connected to the Internet. P2P is configured and administered by using Netsh commands.

You can run these commands from the command prompt for the Netsh P2P context. For these commands to work at the command prompt, you must type netsh p2p before typing commands and parameters as they appear in the syntax below.

For more information about netsh, see Netsh Overview and Enter a Netsh Context.

  • Netsh P2P

  • Netsh P2P collab

  • Netsh P2P group

  • Netsh P2P idmgr

For information on how to interpret netsh command syntax, see Formatting Legend.

Syntax

set file [ mode= ] { open [ name= ] <filename> | append [ name = ]<filename> | close }

Parameters

  • Mode
    One of the following values:

    • Open: Creates a new file or overwrites an existing file and streams the console output to the file.

    • Append: Opens an existing file and streams the console output to the end of the existing file.

    • Close: Stops streaming and closes a file.

  • Name
    Name of the file (full path optional)

Examples

set file open c:\logfiles\logfile.txt

The above command creates a file and logs all output to it.

set machinename

Configure the PNRP Machine Name Publication Service.

Syntax

set machinename [[name=]<PeerName>] [[publish=]Start|Stop] [[autopublish=]enable|disable]

Parameters

  • Name
    The name to use as the machine name. If value is null, a secured name is automatically generated.
  • Publish
    If set to 'start,' will cause the name to start being published immediately. If set to 'stop,' will stop the publication of the name.
  • Autopublish
    Sets whether or not automatic publication is enabled. When autopublish is enabled, the machine automatically begins publishing the name at boot.

Remarks

This command allows the user to control the publication of a Peer Name

for the machine using the Peer Name Resolution Protocol (PNRP).

If you use this functionality, it will allow you to resolve the Peer

Name of this machine from other remote machines subject to network

reachability. If you start publication through this command without

setting a name, then a secured name will be automatically generated

for you and will be visible through the 'show machinename' command.

Examples

set machinename publish=start autopublish=enable

set mode

Sets the current mode to online or offline.

Syntax

set mode [ mode= ] { online | offline }

Parameters

  • Mode

    • offline: Delay commit until explicitly requested

Example

Set mode online

Syntax

show registration [[cloud=]<cloud name>]

Example
