Remote Cellular TCP/IP Access to Rockwell Ethernet and Serial Devices
Remote Cellular TCP/IP to Rockwell Devices Remote Cellular TCP/IP Access to Rockwell Ethernet and Serial Devices Keywords: Cellular, SLC5/05, ControlLogix, MicroLogix Abstract: This document describes how to set up the Digi Connect™ WAN products (Digi Connect WAN, Digi Connect WAN RG, and Digi Connect WAN VPN) for remote cellular TCP/IP access to Rockwell equipment, such as the PLC5E, SLC5/05, ControlLogix, and MicroLogix. The Digi Connect WAN Family functions much like a home DSL/Cable modem, except the connection is by digital cellular signals such as GSM or CDMA. This enables wireless “Ethernet” solutions on a metro, regional, or global scale. 1 Introduction 1.1 Example Application To illustrate the use of Digi Connect WAN products with your Rockwell equipment, consider the following example: Key Features: The Digi Connect WAN product used with your Rockwell equipment provides several key features: • Provides outgoing Network-Address-Translation (NAT) and incoming TCP/UDP port forwarding. Some models act as VPN end-point. • Maintains an always-up IP connection, either on either the public Internet or by customized private networks established through your cellular carrier. • Being IP-based, all common Ethernet protocols can be used concurrently, including HTTP (Web browsing), ODVA Ethernet/IP, CSPv4, and Modbus/TCP. PN: 90000772_A http://www.digi.com/support/ia Page 1 of 37 Remote Cellular TCP/IP to Rockwell Devices • Existing applications, such as RSLinx, RSLogix and OPC, can be configured to access the field equipment through existing corporate LAN connections. • Intelligent field devices can use IP-based protocols to send email, file updates, or report-by-exception notifications. -

Microsoft DNS
1 a. Domain Name Service (DNS) encompassing Microsoft DNS From Wikipedia, the free encyclopedia Jump to: navigation, search Microsoft DNS is the name given to the implementation of domain name system services provided in Microsoft Windows operating systems. Contents [hide] 1 Overview 2 DNS lookup client o 2.1 The effects of running the DNS Client service o 2.2 Differences from other systems 3 Dynamic DNS Update client 4 DNS server o 4.1 Common issues 5 See also 6 References 7 External links [edit] Overview The Domain Name System support in Microsoft Windows NT, and thus its derivatives Windows 2000, Windows XP, and Windows Server 2003, comprises two clients and a server. Every Microsoft Windows machine has a DNS lookup client, to perform ordinary DNS lookups. Some machines have a Dynamic DNS client, to perform Dynamic DNS Update transactions, registering the machines' names and IP addresses. Some machines run a DNS server, to publish DNS data, to service DNS lookup requests from DNS lookup clients, and to service DNS update requests from DNS update clients. The server software is only supplied with the server versions of Windows. [edit] DNS lookup client Applications perform DNS lookups with the aid of a DLL. They call library functions in the DLL, which in turn handle all communications with DNS servers (over UDP or TCP) and return the final results of the lookup back to the applications. 2 Microsoft's DNS client also has optional support for local caching, in the form of a DNS Client service (also known as DNSCACHE). Before they attempt to directly communicate with DNS servers, the library routines first attempt to make a local IPC connection to the DNS Client service on the machine. -

B. TECH, COMPUTER SCIENCE AND ENGINEERING Student, 3rd year-2nd Semester GITAM UNIVERSITY Visakhapatnam, Andhra Pradesh India 2.Assistant Professor Computer Science and Engineering GITAM UNIVERSITY Visakhapatnam, Andhra Pradesh India ABSTRACT This paper is focused on the evolution of SSH, the need for SSH, working of SSH, its major components and features of SSH. As the number of users over the Internet is increasing, there is a greater threat of your data being vulnerable. Secure Shell (SSH) Protocol provides a secure method for remote login and other secure network services over an insecure network. The SSH protocol has been designed to support many features along with proper security. This architecture with the help of its inbuilt layers which are independent of each other provides user authentication, integrity, and confidentiality, connection- oriented end to end delivery, multiplexes encrypted tunnel into several logical channels, provides datagram delivery across multiple networks and may optionally provide compression. Here, we have also described in detail what every layer of the architecture does along with the connection establishment. Some of the threats which Ssh can encounter, applications, advantages and disadvantages have also been mentioned in this document. Keywords: SSH, Cryptography, Port Forwarding, Secure SSH Tunnel, Key Exchange, IP spoofing, Connection- Hijacking. 1. INTRODUCTION SSH Secure Shell was first created in 1995 by Tatu Ylonen with the release of version 1.0 of SSH Secure Shell and the Internet Draft “The SSH Secure Shell Remote Login Protocol”. -

Stateless DNS
Technical Report KN{2014{DiSy{004 Distributed System Laboratory Stateless DNS Daniel Kaiser, Matthias Fratz, Marcel Waldvogel, Valentin Dietrich, Holger Strittmatter Distributed Systems Laboratory Department of Computer and Information Science University of Konstanz { Germany Konstanzer Online-Publikations-System (KOPS) URL: http://nbn-resolving.de/urn:nbn:de:bsz:352-0-267760 Abstract. Several network applications, like service discovery, file dis- covery in P2P networks, distributed hash tables, and distributed caches, use or would benefit from distributed key value stores. The Domain Name System (DNS) is a key value store which has a huge infrastructure and is accessible from almost everywhere. Nevertheless storing information in this database makes it necessary to be authoritative for a domain or to be \registered" with a domain, e.g. via DynDNS, to be allowed to store and update resource records using nsupdate . Applications like the ones listed above would greatly benefit from a configurationless approach, giving users a much more convenient experience. In this report we describe a technique we call Stateless DNS, which allows to store data in the cache of the local DNS server. It works without any infrastructure updates; it just needs our very simple, configurationless echo DNS server that can parse special queries containing information desired to be stored, process this information, and generate DNS answers in a way that the DNS cache that was asked the special query will store the desired information. Because all this happens in the authority zone of our echo DNS server, we do not cause cache poisoning. Our tests show that Stateless DNS works with a huge number of public DNS servers. -
Nokia HA-140W-B
Port forwarding for Nokia HA-140W-B Port forwarding can be used to establish a home-based FTP server, web server or similar kind of a server. The server is located on the LAN client (e.g. desktop computer or laptop). To set up Port forwarding, log into your router and go to Application > Port Forwarding. See image 1. Image 1. Port forwarding configured with port mapping (WAN port maps to LAN port) To set a specific port forwarding rule, select Custom settings for Application Name line. In the WAN Port field, set an arbitrary port on WAN interface of a router (e.g. TCP port 12001). All requests coming to the server from the internet side will have a destination IP address of the router itself, and a destination port as listed in WAN Port fields. For LAN port fields, list the port on which the LAN client server app is running (in this case TCP port 8008). Select the appropriate LAN client (server machine) from the dropdown menu on Internal Client. Protocol is determined by the type of server application (in this case TCP). Tick Enable Mapping and click Add to save the rule. Once the rule is saved, you’ll see the confirmation (see image 2). 1 Image 2. Port forwarding rule confirmation Similarly, ports on WAN and LAN side can be kept the same (see image 3). Image 3 shows the second way things can be configured. It’s up to you whether you prefer to use the methods in image 1 or image 3. Image 3. -

Doodle Labs Smart Radio Advanced MIMO Mesh Router in a Tiny Form Factor
Configuration Guide Doodle Labs Smart Radio Advanced MIMO Mesh Router in a tiny Form Factor Introduction The Smart Radio runs a customized version of Openwrt with enhancements related to the Doodle Labs Mesh Rider® technology. These enhancements are useful for applications requiring low-latency command-and- control transmission and high-throughput video - e.g. UAV and robotics. The purpose of this guide is to aide a programmer in re-configuring common Smart Radio settings once it is deployed in the field. A full technical discussion of all of the different configuration parameters of the Openwrt system is beyond the scope of this guide, and the user is encouraged to explore the OpenWrt website. Smart Radio Configuration Overview Factory Configuration By default, the Smart Radio is configured to connect to a mesh network as shown in the diagram in the next section. There are two networks configured in each Smart Radio. The first is the mesh network, and the second is the configuration network. • The mesh network consists of all Smart Radios and host platforms which join the mesh. ETH0 is bridged to the mesh network. The firewall is set up to allow input access using SSH or the web GUI. The mesh network has two IP addresses. o The first is a DHCP client. o The second is a static IP address equal to 10.223.x.y where x.y is the last four hexadecimal digits of the wireless MAC address. For example, a unit shipped with MAC address 00301A4E7AB0 has the last four HEX digits 7AB0 and x.y is equal to 122.176.
