Peer to peer networking disabled diablo 2

Local clients. Use the ntp server command to individually specify the time server that you want your networking device to consider synchronizing with and to set your networking device to operate in the client mode. When a networking device is operating in the symmetric active mode, it polls its assigned time-serving hosts for the current time and it responds to polls by its hosts. Because this is a peer-to-peer relationship, the host will also retain time-related information of the local networking device that it is communicating with. This mode should be used when a number of mutually redundant servers are interconnected via diverse network paths. Most stratum 1 and stratum 2 servers on the Internet adopt this form of network setup. Use the ntp peer command to individually specify the time serving hosts that you want your networking device to consider synchronizing with and to set your networking device to operate in the symmetric active mode. The specific mode that you should set for each of your networking devices depends primarily on the role that you want them to assume as a timekeeping device (server or client) and the device’s proximity to a stratum 1 timekeeping server. A networking device engages in polling when it is operating as a client or a host in the client mode or when it is acting as a peer in the symmetric active mode. Although polling does not usually place a burden on memory and CPU resources such as bandwidth, an exceedingly large number of ongoing and simultaneous polls on a system can seriously impact the performance of a system or slow the performance of a given network. To avoid having an excessive number of ongoing polls on a network, you should limit the number of direct, peer-to-peer or client-to-server associations. Instead, you should

Several mutually redundant servers that are interconnected via diverse network paths. Most stratum 1 and stratum 2 servers on the Internet today adopt this form of network setup. Use the peer command to individually specify the time-serving hosts that you want your networking device to consider synchronizing with and to set your networking device to operate in the symmetric active mode. When the router polls several other devices for the time, the router selects one device with which to synchronize. Note To configure a peer-to-peer association between the router and another device, you must also configure the router as a peer on the other device. You can configure multiple peers and servers, but you cannot configure a single IP address as both a peer and a server at the same time. To change the configuration of a specific IP address from peer to server or from server to peer, use the no form of the peer or server command to remove the current configuration before you perform the new configuration. If you do not remove the old configuration before performing the new configuration, the new configuration does not overwrite the old configuration.

OS X and iOS provide four APIs for discovering and advertising network services:NSNetService—A high-level Objective-C API suitable for most app developers.CFNetService—A high-level C API suitable for use in Core Foundation code.DNS Service Discovery—A low-level C API suitable for cross-platform code. This API also offers more flexibility than the higher-level APIs.Game Kit framework—A high-level Objective-C API that provides peer-to-peer communication support for games, both locally (using infrastructure Wi-Fi and Bluetooth) and globally over the Internet.In addition to these APIs, the Multipeer Connectivity Framework provides support for discovering and communicating with instances of your app and related apps on nearby devices using infrastructure Wi-Fi, peer-to-peer Wi-Fi, and either Bluetooth (for iOS) or Ethernet (for OS X).As a rule, you should use Game Kit only for game-related peer-to-peer networking. For other peer-to-peer networking between iOS devices running iOS 7 and later, you should consider using the Multipeer Connectivity framework.For compatibility with older versions of iOS, you can also write your own networking code and use CFNetService or NSNetService to advertise its availability.Bonjour Service OverviewA Bonjour service advertisement consists of three parts:Service name—This name must be unique to a particular instance of your program running on a particular computer.Service type—This must be the same for all instances of your program, and should be registered with the Internet Assigned Numbers Authority (IANA).Domain—If the domain value is empty, the host chooses the appropriate domains in which to publish or browse.When an app browses for Bonjour services, it asks for services matching a particular type in a
