  • Universal Plug and Play: Dead Simple Or Simply Deadly?
    Universal Plug and Play: Dead simple or simply deadly? Armijn Hemel April 7, 2006 1 Universal Plug and Play overview Many devices and programs that exist today have support for the Universal Plug and Play (UPnP) protocol. The UPnP protocol emerged from within Microsoft in early 1999 to bring the plug and play concept as found on Windows desktop machines to the local network. The idea behind UPnP is to enable a user to plug a device into the local network and it will simply work, whether the device is a printer, scanner, fileserver or firewall. All configuration is hidden for the user and instead done automatically by the devices and programs themselves. The first implementations of UPnP were shipped halfway 2000, Windows ME and Intel's open source UPnP SDK for Linux being the first. Windows XP also had UPnP support built-in since its release in 2001. There are currently implementa- tions for various operating systems, including Windows, VxWorks, Linux[1][2] and FreeBSD[1][2]. The UPnP protocol stack uses well-defined Internet standards, such as HTTP, XML and SOAP. One of the best known programs that uses UPnP is Microsoft's MSN Messenger. Ports that need to be opened on the firewall for voice and video traffic (the \web- cam" feature) and direct file transfers in MSN Messenger are allocated dynamically using UPnP. This is done by sending special UPnP commands to a UPnP enabled firewall if the machine that runs MSN Messenger is behind a firewall or NAT de- vice and cannot communicate with the other machine directly.

  • Jini and Universal Plug and Play (Upnp) Notes
    Jini and Universal Plug and Play (UPnP) Notes Abstract Jini and UPnP are overlapping technologies. They both address the area of device connectivity and the ability to dynamically make use of new devices on the network. The emphasis in UPnP is on hardware devices offering services, whereas Jini emphasises services – both software and hardware. UPnP seems to focus on providing the ability of devices to join a network and have those devices provide an API (via HTTP and SOAP) by which other devices on the network can run their software using the offered API. Jini is aimed at providing a broad framework for provisioning distributed computing which includes device collaboration on a network, but also includes additional, required components for robust service offerings across both a LAN and WAN. Probably the most important component to meet the goal of robust distributed computing on a network is the concept of providing code mobility between devices and application spaces. The following document provides an outline of the basics features or functions required for distributed service offering, and tries to compare the methods of providing these services by UPnP and Jini.

    Plug-and-play bug exposes millions of network devices 12 June 2020, by Peter Grad traffic, block legitimate traffic, overwhelm processing resources and cause the systems to crash. Çadirci operates a website dedicated to information about the CallStranger vulnerability. He first detected it late last year and notified the Open Connectivity Foundation, which has since updated UPnP specifications to address the issue. Vendors and Internet service providers requested notice of the vulnerability be withheld until they had time to address the issue. "Because this is a protocol vulnerability, it may take a long time for vendors to provide patches," Çadirci said in his report. Since some manufacturers have Credit: Pixabay/CC0 Public Domain not yet corrected the issue and many IoT devices never receive updates, consumers should contact manufacturers of any UPnP devices they use to determine if software or hardware patches are A bug in a protocol used by virtually all Internet of available.

  • How to Configure a Upnp Internet Gateway Device with Windows XP
    How To | Configure A Router As A UPnP Internet Gateway Device With A Windows® XP® Machine As A UPnP Control Point Introduction This How To Note describes how to configure your router as a UPnP Internet Gateway Device (IGD), and provides a configuration example for setting up UPnP components. This note also outlines how to configure your Windows® XP® machine as a UPnP control point. Note: This How To Note describes the Allied Telesis implementation of InternetGatewayDevice:1 Device Template Version 1.01 for Universal Plug and Play Version 1.0. Although every effort has been made to comply with the Internet Gateway Device:1 Device Template Version 1.01 Standardized DCP, this implementation has not been certified by the UPnP Implementers Corporation. Which products and versions does it apply to? This document applies to the following Allied Telesis routers: z AR720 and AR740 routers, running software release 2.6.4 or later z other AR700 series routers, running software release 2.7.1 or later z AR400 series routers, running software release 2.7.1 or later Related How To Notes You may also find the following How To Note useful: z How To Configure UPnP How To Notes are available from www.alliedtelesis.com/resources/literature/howto.aspx. C613-16001-00 REV B www.alliedtelesis.com What is Universal Plug and Play (UPnP)? Universal Plug and Play (UPnP) is an architecture that allows for dynamic connectivity between devices on a network. Devices may dynamically add themselves to a network without the need for user intervention or configuration. A UPnP-enabled device may obtain an IP address, advertise its capabilities, learn about other connected UPnP devices and then communicate directly with those devices.

  • Universal Plug and Play (Upnp) Configuration on the RV120W Routers
    Universal Plug and Play (UPnP) Configuration on the RV120W Routers Objectives Universal Plug and Play (UPnP) is a network protocol that allows devices to discover each other on the network. The discovered devices can then establish network services for data sharing, communications, and entertainment. UPnP also include a feature that automatically configure the router to open and close ports for internet application, such as gaming. One of the main feature that UPnP option provide is that, when connected to a network they automatically establish working configurations with other devices.The UPnP architecture allows device-to-device networking of personal computers, network capable home appliances, electronics devices and wireless devices. This document explains how to set up UPnP on the Cisco RV120W routers. Applicable Devices • RV120W Software Version • 1.0.4.10 UPnP Configuration Step 1. Log into the web configuration utility and choose Administration > Discovery Settings > Discovery-UPnP. The Discovery - UPnP page opens: Step 2. Check Enable to enable UPnP. Step 3. In Advertisement Period, enter the value in number of seconds,. This will broadcast its UPnP information to all devices within range. Step 4. In Advertisement Time to Live field, enter the value in number of seconds. This will broadcast that an advertisement is active. Note: If the value is 100 or higher in Advertisement Time To Live, this eliminates the need to turn UPnP on/off after each reboot. The UPnP Interface Control Table displays the information: • VLAN ID number —VLAN ID can range from 2 to 4094, VLAN ID 1 is reserved for the default VLAN, which is used for untagged frames received on the interface, and VLAN ID 4092 is reserved and cannot be used .
