Registered ports are 1024 to 49151. TCP/IP Sockets in Java: Practical Guide for Programmers (The Practical Guides) [Kenneth L. iproxy comprises of a client-side proxy and a server-side proxy that allows arbitrary TCP/IP services to run over Broadcast, Multicast or Unicast UDP. The TCPServer class is a class derived from the socketserver. For Example: UDP client sents a broadcast message to IP address 192. To satisfy this with EC2 server hardware at a default limit of 4,096 TCP connections we would need 34,424 EC2 servers. Registered ports. at the same time. The main difference is the server loop. A simple Java TCP/IP server and client socket application is created in this example. The following articles describe features of the HTTP client API. use Discovery to detect brokers (multicast or rendezvous). channel() with a class. Here is the Java code for the data generating server. That the daemon process is written in C doesn't really matter if you are communicating with it via TCP/IP packets. HTTP client API. This java temperature conversion application converts temperature between Celsius, Kelvin, Fahrenheit, Reaumur and Rankine scales. You broadcast a WebTemplate which contains several tabs. It introduces some basic concepts and terminology related to networks and TCP/IP. Let's cover Java TCP sockets first since they are much simpler than Swing. , and a different application could move into 9876 UDP Ln. TCP is reliable protocol. Unfortunately, you can’t tell it how frequently to send the heartbeat probes. TCP/IP Sockets in C Practical Guide for Programmers Second Edition Michael J. Java not needed in 10. This kind of socket is used on the client-side to listen for packets that the server broadcasts to multiple clients. Port TCP UDP Description Status 0 UDP Reserved Official 1 TCP UDP TCP Port Service Multiplexer (TCPMUX) Of. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) needed only one port for full-duplex, bidirectional traffic. There is no such thing as TCP multicast or broadcast or even unicast. Opening a lot of TCP connections to a lot of clients is not broadcast. Unicast is anything that is not broadcast nor multicast. exe from debug folder, and you can open the client exe for many form at he same time. Java Socket programming is used for communication between the applications running on different JRE. Modbus TCP/IP clients and servers listen and receive Modbus data via port 502. Chat Application using TCP Socket in Java. transport and routing is provided by Ethernet mechanisms. HTTP client API. Most importantly UDP is a connectionless protocol. MulticastSocket-class. webpush 1001. Donahoo Kenneth L. net) takes care of all of. Can you explain the difference between UDP and TCP internet protocol (IP) traffic and its usage with an example? A. Options 0 and 1 are exactly one octet which is their kind field. Well-known ports range from 0 through 1023.

Apache ActiveMQ™ is the most popular open source, multi-protocol, Java-based messaging server. It is represented with the 255. Chat Program Java is a continuous communication between two systems. What this means is that you cannot do broadcast transmissions to multiple device in TCP like you could with a serial connection. TCP/IP (Transmission Control Protocol/Internet Protocol) is the globally accepted group of protocols that form the core of the Internet and organizational intranets. The server can send data to the client at any time. Socket programming boils down to two systems communicating with one. Net Tutorial. 0 license) for embedded tcp/ip free download - SourceForge. Java TCP Socket 编程 TCP 的 Java 支持 协议相当于相互通信的程序间达成的一种约定,它规定了分组报文的结构、交换方式、包含的意义以及怎样对报文所包含的信息进行解析,TCP/IP 协议族有 IP 协议、TCP 协议和 UDP 协议。. The beauty of Java sockets is that no knowledge whatsoever of the details of TCP is required. 2)Print Exception stack trace in catch block to know exception. import java. This information is useful for troubleshooting, and when configuring a firewall to allow Reflection connections. A multicast socket is based on a group membership. It accomplishes this task by having the sender break up the input data into data frames (typically a few hundred or few thousand bytes) and transmit the frames sequentially. He described it as being like HTTP, but faster and less reliable. If UDP broadcast method was unsuccessful, TCP connect may allow you to pass through software/hardware firewalls. Project 1 Implement the project as described using Java Sockets (TCP). Because it runs over TCP, it also provides a low-latency low-level communication and reduces the overhead of each message. Socket programming boils down to two systems communicating with one. Splunk logging for Java enables you to log events to HTTP Event Collector or to a TCP input on a Splunk Enterprise instance within your Java applications.

IPPROTO_UDP says that it will use the UDP protocol (the standard transport layer protocol for datagrams in IP networks). It is represented with the 255. A multithreaded client/server Chat application based on the console which uses Java Socket programming and multi-threading. Java Socket programming can be connection-oriented or connection-less. TCP Java Socket or Robust Socket [5] we show that VSC solves Reliable Broadcast in a system model with "program-controlled crash". Unlike UDP, TCP is a connection-oriented protocol. If you are on a LAN, UDP broadcasting might work; receivers could keep track of a list of the packets they haven't yet gotten, and when the initial broadcast ends, they can requests updates. Well-known ports range from 0 through 1023. This basically means I had to emulate TCP over UDP. Port TCP UDP Description Status 0 UDP Reserved Official 1 TCP UDP TCP Port Service Multiplexer (TCPMUX) Of. TCP and UDP are used to deliver data from one end to another, but still, there is a slight difference in their structure, working. 1, NetBSD 5.

Calvert AMSTERDAM •BOSTON HEIDELBERG LONDON NEW YORK •OXFORD PARIS • SAN DIEGO SAN FRANCISCO •SINGAPORE SYDNEY TOKYO Morgan Kaufmann Publishers is an imprint of Elsevier. In TCP data is sent over the network quickly but in UDP data is sent in different segments. The exploits are all included in the Metasploit framework and utilized by our penetration testing tool, Metasploit Pro. Within each Namespace, you can also define arbitrary channels (called room) that the Socket can join and leave. 0 is the network number. Most importantly UDP is a connectionless protocol. This article provides an overview of ports that are used by Citrix components and must be considered as part of Virtual Computing architecture, especially if communication traffic traverses network components such as firewalls or proxy servers where ports must be opened to ensure communication flow. Red5; Red5 Pro. Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker. in what sort of applications we have to use UDP? or in other words in what situation using UDP is more beneficial than TCP?. GitHub Gist: instantly share code, notes, and snippets. It is also shown how to run the socket application with the java command and how to use Wireshark for monitoring TCP/IP network traffic between the server and client socket. From the man page: /dev/tcp/host/port If host is a valid hostname or Internet address, and port is an integer port number or service name, bash attempts to open a TCP connection to the corresponding socket. Otherwise you could receive data twice, or data that isn't part of the connection, and TCP is defined not to do that. The client is able to read two numbers from its keyboard and then to send two numbers to the server. The following example program creates a server that receives connection requests from clients. The requirements make sense and the common usages for UDP fit these requirements. Unfortunately, you can’t tell it how frequently to send the heartbeat probes. A curated repository of vetted computer software exploits and exploitable vulnerabilities. IO::Socket::INET provides an object interface to creating and using sockets in the AF_INET domain. Port Unreachable" message. This method is commonly refered to as a UDP rendezvous. Java Chat room application using UDP The following is a Java program for chatting. Ping/HTTP Calls 8000 servers in 12 seconds. The Linux Socket Programming book cites several programs which were too lengthy to include entirely in the text. To broadcast, you need to use a UDP socket (DatagramSocket). This will be a connection-oriented client-server system with reliability built-in since TCP provides guaranteed delivery. * This was created to work with the program UDP_Minimum_Listener. These messages are sometime called events or intents. The TCP stack on kang receives the ACK for the FIN and removes the connection entirely. Similar to remote X11, the TCP transport has no integrity or confidentiality protection, so it should normally only be used across the local loopback interface, for example using an address like tcp:host=127. com, and Cisco DevNet. The unit id of 0 can be seen as a broadcast address. This chapter provides an introduction to the book, TCP/IP Sockets in Java: Practical Guide for Programmers, the goal of which is to help understand how a program communicates with another program over a network, in the context of the Java programming language. Netty TCP can be configured to use old blocking Java IO or non blocking Java NIO. , and a different application could move into 9876 UDP Ln. A responsive and accurate temperature converter program can be made using java. It is most widely used protocol for data transmission in communication network such as internet. net package. コンピュータネットワークにおいて、インターネット・プロトコル・スイートのトランスポート層にあたるTransmission Control Protocol (TCP) やUser Datagram Protocol (UDP) では、他のプロトコル同様、ホスト間通信のエンドポイントを指定する際に数字の. java because it will later be implemented (probably).

It is a Java application that allows you to play with different slaves (registers and coils). I also guide them in doing their final year projects. Hinden in 1982. The second method of sending messages is called the broadcasting. The following rules allow outgoing ssh connection. 1, NetBSD 5. the broadcast address used is suitable for the client machine, and the client machine is permitted to print to the queues of. Full form TCP stands. DatagramPacket; import java. Calvert, Michael J. It implements a TUN virtual network interface which accepts all incoming TCP and UDP, and forwards them through a HTTP, SOCKS4, SOCKS 5. It should be noted the Socket doesn't relate directly to the actual underlying TCP/IP socket and it is only the name of the class. In this chapter, we're going to extend Python Network Programming I - Basic Server / Client A, and try to file transfer from a server to numerous clients. It is written in Java, runs an all major platforms and it is easy to use. Utilisez la procédure suivante pour configurer le sous-système JGroups pour qu'il puisse utiliser la monodiffusion TCP à la place. But my problem, and with this article its the same, is that this article and a lot of other questions about tcp vs udp started a huge discussion about tcp evangelists vs udp evangelists :D. The TCP and UDP binding is built on top of camel-netty and supports most of options for this endpoint. TCP and UDP Port Configuration Quick Reference Guide Solution The following table has been created to show the communication ports used by individual products. RT communications bypass the standard TCP/IP interface to expedite the data exchange with Programmable Controllers. Problem Description. Channel endpoints have unique names within a facility, and the default name resolution method is UDP broadcast prior to connection. DatagramSocket class in Java Datagram socket is a type of network socket which provides connection-less point for sending and receiving packets. Java Program to Implement Broadcasting System Between a Server and Many Clients Screenshot of broadcast server and clients using java In this post we will see a java program which implements a broadcasting system. Although not developed under the OSI Reference Model and not strictly conforming to the OSI definition of the transport layer, the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) of the Internet Protocol Suite are commonly categorized as layer-4 protocols within OSI. Port Unreachable" message. The EPICSv4 network protocol is pvAccess. You can vote up the examples you like. Your votes will be used in our system to get more good examples. HI –FI Infirmary Portal Java Project Report. -Also, on the client you don't need to declare a new reader everytime you move through the while loop. TCP and UDP Client Server Programs In JAVA In addition, DatagramPackets can be broadcast to multiple recipients all listening to a MulticastSocket. I designed and implemented the deep packet inspection (DPI) configurations on Nokia GGSN equipments, including DNS sniffing to identifying and categorizing traffic in different layers (L3-L4 and L7-HTTP/HTTPS), based on IP header information (TCP/UDP) in order to create differentiated traffic treat for specific services and products (provider. 1x A standard that blocks all traffic on a port-by-port basis until the client is authenticated using credentials store on an authentication server. This is a list of TCP and UDP port numbers used by protocols of the Internet protocol suite for operation of network applications. the broadcast address used is suitable for the client machine, and the client machine is permitted to print to the queues of. This solution explains a socket approach to sending a message (broadcast message) to clients in the same VLAN (Virtual Lan). It can be used to test any server or client that uses TCP or UDP protocol to communicate. In general, a computer network composed of one or more servers, workstations, network interface cards, active and passive hub, routers, bridges, gateways, modem, software components like network operating systems, and other application software. In the TCP protocol first a connection is established by. A TCP application layer Internet protocol engages two computer processes linked by a single or multiple (e. tcp/ip library free download. Here is an example of how a very simple client-server chat application works. When shutdown is called on TCP server sockets, the effect should be to close the listening socket, and discard all incoming connections in the listen queue. Here is an example on using pthread condition variables: In thr_func1(), we are locking the count_lock mutex so we can read the value of count without entering a potential race condition. When a packet arrive at network layer, how to know which application to send to?. 0, than broadcast address is 10. AMQP 0-9-1 Overview and Quick Reference. 255 TCP/IP address. Unlike in the case of point-to-point communication, we don’t have to know the target host’s IP Address. TCP provides a much richer functionality for sending data, but requires that the remote socket first be connected. Here is an example on using pthread condition variables: In thr_func1(), we are locking the count_lock mutex so we can read the value of count without entering a potential race condition. The destination address in the packet is the special broadcast address. A private network address is an IP address range that is used only within the confines of a single organization. TCP/IP layers (contd. We are running +141 million TCP connections concurrently. Sockets are a low-level data transfer technology on top of which many networking protocols are implemented. Sockets Imports. There are two types of Broadcast: Limited Broadcast - Sent to all NICs on the some network segment as the source NIC. See also port 888. Plus quelques tutoriels. Project 1 Implement the project as described using Java Sockets (TCP). Broadcast networks. Traditionally, this operation is called "assigning a name to a socket". Note that you can implement TCP behaviour with UDP. The Transmission Control Protocol. This article only gives you a simple idea as how to implement a duplex WCF service to broadcast events to all connected clients. 5 build 57 and newer. I want to know what I can do better in terms of exception handling (and otherwise) in the below code Server import java. Après tu fais références au modèle OSI, repose ta question plus précisement, mais je peux déjà te dire que seul le modèle TCP/IP correspond à TCP/IP et que le modèle OSI n'est pa un réel modèle mise en pratique, c'est uniquement un modèle de référence (un langage commun à chacun). The requirements make sense and the common usages for UDP fit these requirements. How to get Server IP Address and Hostname in Java Last Updated on July 16th, 2017 by App Shah 4 comments In Java, you can use InetAddress. As part of the upgrade the vendor offered to supply anti-malware software for a cost of $5,000 per year. Our TCP/IP, IP and IPv6 training courses range from non-technical training to 'hands on' engineering courses in live classroom labs, and include topics such as the OSPF and BGP4 protocols, network security and IPv6.

Java ME is a platform for applications running on mobile phones. 0 is the network number. Socket and ServerSocket classes are used for connection-oriented socket programming and DatagramSocket and DatagramPacket classes are used for connection-less socket programming. This chatting application uses UDP (User Datagram Pr How to Change Shape of JFrame - Rounded Rectangle, Circle, Ellipse etc. The following articles describe features of the HTTP client API. In computer networking, the protocols of the Transport Layer of the Internet Protocol Suite, most notably the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP), but also other protocols, use a numerical identifier for the data structures of the endpoints for host-to-host communications. Connection Transmission Control Protocol is a connection-oriented protocol. How to create a multithreaded server ? Solution. In this case that’s NioServerSocketChannel which is an implementation of ServerChannel. rmi)!!RMI allows distributed components to be manipulated. In the TCP protocol first a connection is established by. It is represented with the 255. TCP is connection oriented - reliable protocol which transfer the data in continues streams. If you want to use TCP connection, then there is NO broadcast. Broadcast is a packet that’s sent to all devices on specific network. When an application no longer needs to be connected to the server, it should gracefully close its AMQP 0-9-1 connection instead of abruptly closing the underlying TCP connection. Data on port 1352 is TCP (Connection orientated) and not UDP(Broadcast). One is known as Transmission Control Protocol while the other is called User Datagram Protocol. txt capsecs=-5 sendquit=outfile. Right-click Local Area Connection, and then click Properties. It is also shown how to run the socket application with the java command and how to use Wireshark for monitoring TCP/IP network traffic between the server and client socket. Since TCP supports only the unicast mode, multicast applications must use the UDP transport protocol. In this article I will show you how to write one in C#. Hello Friends, I am Free Lance Tutor, who helped student in completing their homework. The source code is available in the Android Open Source Project, and you can get started with it in the Reference TV app article. Robust TCP Connections for Fault Tolerant Computing. Overview of networking facilities in java. Anyway TIME_WAIT has nothing to do with UDP. Check SNMP counters. This gives you the classes you need for network communication. Utilisez la procédure suivante pour configurer le sous-système JGroups pour qu'il puisse utiliser la monodiffusion TCP à la place. In order to do communication over the TCP protocol, a connection must first be established between the pair of sockets. This is a list of TCP and UDP port numbers used by protocols of the Internet protocol suite for operation of network applications. net package • import java.

This chapter provides an introduction to the book, TCP/IP Sockets in Java: Practical Guide for Programmers, the goal of which is to help understand how a program communicates with another program over a network, in the context of the Java programming language. net) takes care of all of. - abhi195/Chat-Server. NET Supports Function Codes: - Re. Otherwise you could receive data twice, or data that isn't part of the connection, and TCP is defined not to do that. The TCP/IP model refers to transmission control protocol and Internet protocol. We have produced a 28 page white paper designed to introduce those not familiar with the field to its nomenclature and the choices to be made when designing a TCP/IP embedded system. A responsive and accurate temperature converter program can be made using java. If you need to connect across subnets, TCP method is the only option. I want to send stuff through an ethernet cable between the two devices. broadcast to. You will be able to create a socket manually, connect it (or listen for connections), send and receive data through it. net, including Addressing, Making TCP Connections, Sending/Receiving Datagram Packets via UDP, Locating/Identifying Network Resources, and Security. Note: Now we have an enhanced version of TCP Connection here, but it's just the code. The following article TCP vs UDP provides an outline of the comparision between both. Après tu fais références au modèle OSI, repose ta question plus précisement, mais je peux déjà te dire que seul le modèle TCP/IP correspond à TCP/IP et que le modèle OSI n'est pa un réel modèle mise en pratique, c'est uniquement un modèle de référence (un langage commun à chacun).

The Java API for WebSocket simplifies the integration of WebSocket into Java EE 7 applications. BaseServer which provides a generic interface for network servers. Wilson's TCP/IP MCSE Microsoft ISO Layers and Protocols The ISO - OSI 7 layer Reference Model (officially known as ISO Standard 7498, 1984, 7498-1:1994. Each of these applications use the client-server paradigm, which we discussed earlier. Real-Time Messaging Protocol (RTMP) was initially a proprietary protocol developed by Macromedia for streaming audio, video and data over the Internet, between a Flash player and a server. All of them are handled via two system calls: setsockopt() (used to pass information to the kernel) and getsockopt() (to retrieve information regarded multicas. In this post, we will see a good temperature converter code. Here, in this tutorial we will learn about TCP/IP Model. If the destination is on the same subnet, ARP is used to figure out the MAC address that goes to the stated IP address. Does java have the capability to send and accept broadcasting UDP packets (to 192. The RMI example allows multiple client programs to communicate with the same server program without any explicit code to do this because the RMI API is built on sockets. TCP Implementation for SWANS Overview The goal of the project is to provide SWANS with TCP layer that can be used for TCP applications such as file transfer, web servers, etc. The transmission Control Protocol (TCP) is one of the most important protocols of Internet Protocols suite. It is a two way communication. Obviously, whenever we connect together device A and device B, there must be some way for A to send to B and B to send to A. It introduces some basic concepts and terminology related to networks and TCP/IP. Well-known ports range from 0 through 1023. If considering extending this example for e. I dis-agree. Abstract: This page describes how to write a simple UDP client/server system in a C/Unix environment. In this article, we describe how one-to-all (Broadcast) and one-to-many (Multicast) communications can be handled in Java. The server can send data to the client at any time. Well-known ports range from 0 through 1023. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. For practice, you can extend it to build a small chat system or a local attendance tracking system. Hi, While going through the hybris OOB features, we observed that we Can\'t use JNDI datasource configuration with JGroups UDP or TCP cluster broadcast method, When we see the source code of JGroupsBroadcastMethod. 30005 (TCP/UDP) Device (UMS agent) Device: The device responds to a broadcast sent by the UMS during a scan. all of we have read in many java books that TCP is connection oriented protocol & UDP is connectionless protocol. 0, than broadcast address is 10. In this case, it's TCP since telnet is designed to use this protocol (tcp)to communicate. You can use ModbusPal to simulate the behavior of a Modbus slave. TCP and UDP Client Server Programs In JAVA In addition, DatagramPackets can be broadcast to multiple recipients all listening to a MulticastSocket. Easy Tutor author of Socket program of multi client chat server is from United States. TCP is reliable protocol. To broadcast on each network, the appropriate broadcast address should be used as an argument to sendto() (or related function). MyLanViewer Network/IP Scanner is a powerful Netbios and LAN/Network IP address scanner for Windows, whois and traceroute tool, remote shutdown and Wake On LAN (WOL) manager, wireless network scanner and monitor. These vulnerabilities are utilized by our vulnerability management tool InsightVM. We will look at four network applications, written completely from scratch in Java. In broadcast, the transmission of a packet is one-to-all whereas, in multicast the transmission of a packet is one-to-many. TCP/IP Sockets in Java Practical Guide for Programmers Second Edition Kenneth L. If the packet has a broadcast address, all devices that receive that message will process it. Socket Programming An Introduction using Java. Received broadcast messages contain the sender's address and port, since datagram sockets are bound before a message is allowed to go out. Advanced TCP/IP 5 Working program examples if any compiled using gcc , tested using the public IPs, run on Linux Fedora 3 with several times update, as normal user. As defined in the tutorial above, an EJB is a re-usable and managed component deployed on J2EE Application Server such as WildFly. Create a simple network application. However, in java there is no shutdown method for server sockets (see ServerSocket and ServerSocketChannel), there is only a close method. • Broadcast networks have a single communication channel that is shared or used by all the machines on the network. , but when another application wants to move into the same house, it finds the house already occupied, so it can't move in. Department of Defense (DoD) to ensure that communications could survive any conditions and that data integrity wouldn't be compromised under malicious attacks. Lesson: All About Datagrams Some applications that you write to communicate over the network will not require the reliable, point-to-point channel provided by TCP. You will be able to create a socket manually, connect it (or listen for connections), send and receive data through it. We're giving away four copies of Reactive Streams in Java: Concurrency with RxJava, Reactor, and Akka Streams and have Adam Davis on-line! See this thread for details. x mainline branch - including UDP proxying improvements in the stream module, random load balancing method, support for TLS 1. WebSocket is a very thin, lightweight layer above TCP. Flash Player System Capabilities JavaScript Disabled — cannot deploy Flash object (it's just for the demo, in fact Flash can work without JavaScript) Flash Detection. The idea behind it is that it is inefficient to broadcast a message in clusters where IP multicasting is not available. Network programming in java - PPT with Easy Programs and examples of Java InetAddress Class and java socket programming example. You can assign DNS and DHCP addresses to all computers on the network. Networking 101: TCP In More Depth Much like broadcast, there are special addresses designated for multicast data. Because it runs over TCP, it also provides a low-latency low-level communication and reduces the overhead of each message. It is most widely used protocol for data transmission in communication network such as internet. Free On-Demand Webinar to How to Make In-The-Moment Decisions Part of Your Mission-Critical Business Process With the rise of artificial intelligence and machine learning, businesses are now able to make hundreds of thousands or even millions of intelligent in-the-moment decisions every day. 5 In the world of browser-based development, interoperability is king. All of them are handled via two system calls: setsockopt() (used to pass information to the kernel) and getsockopt() (to retrieve information regarded multicas. For example, DHCP requests will always come from port 67 on a client, and the DHCP service (the server component) always listens on port 68. nsc or Netshow channel is generated which is then delivered to the user from the server. To chyba głupie pytanie ale cz. The first one separates the headers from the body of the HTTP request. import java. Obviously, whenever we connect together device A and device B, there must be some way for A to send to B and B to send to A. The server sets up a socket and generates data of the form "username:event", where event could be "login" or "purchase". If a button is clicked in this UI, the server would then be able to handle passing data back to the client via the ASP. Make sure that < broadcast_setting_authorization_user > has S_RS_COMP1 / RSZCOMPID=* authorization. (Transmission Control Protocol. As defined in the tutorial above, an EJB is a re-usable and managed component deployed on J2EE Application Server such as WildFly.

Wilson's TCP/IP MCSE Microsoft ISO Layers and Protocols The ISO - OSI 7 layer Reference Model (officially known as ISO Standard 7498, 1984, 7498-1:1994. This article helps you understand InetAddress - a fundamental class in Java Network API. c and the (2) process_put function in sftp. Setting up Cassandra Cluster in Virtual Machines Intro From time to time having just one Cassandra instance installed on your machine is not enough because you want to test certain behaviors when Cassandra cluster is up and running. ZeroMQ (also known as ØMQ, 0MQ, or zmq) looks like an embeddable networking library but acts like a concurrency framework. The fact-checkers, whose work is more and more important for those who prefer facts over lies, police the line between fact and falsehood on a day-to-day basis, and do a great job. Today, my small contribution is to pass along a very good overview that reflects on one of Trump’s favorite overarching falsehoods. Namely: Trump describes an America in which everything was going down the tubes under  Obama, which is why we needed Trump to make America great again. And he claims that this project has come to fruition, with America setting records for prosperity under his leadership and guidance. “Obama bad; Trump good” is pretty much his analysis in all areas and measurement of U.S. activity, especially economically. Even if this were true, it would reflect poorly on Trump’s character, but it has the added problem of being false, a big lie made up of many small ones. Personally, I don’t assume that all economic measurements directly reflect the leadership of whoever occupies the Oval Office, nor am I smart enough to figure out what causes what in the economy. But the idea that presidents get the credit or the blame for the economy during their tenure is a political fact of life. Trump, in his adorable, immodest mendacity, not only claims credit for everything good that happens in the economy, but tells people, literally and specifically, that they have to vote for him even if they hate him, because without his guidance, their 401(k) accounts “will go down the tubes.” That would be offensive even if it were true, but it is utterly false. The stock market has been on a 10-year run of steady gains that began in 2009, the year Barack Obama was inaugurated. But why would anyone care about that? It’s only an unarguable, stubborn fact. Still, speaking of facts, there are so many measurements and indicators of how the economy is doing, that those not committed to an honest investigation can find evidence for whatever they want to believe. Trump and his most committed followers want to believe that everything was terrible under Barack Obama and great under Trump. That’s baloney. Anyone who believes that believes something false. And a series of charts and graphs published Monday in the Washington Post and explained by Economics Correspondent Heather Long provides the data that tells the tale. The details are complicated. Click through to the link above and you’ll learn much. But the overview is pretty simply this: The U.S. economy had a major meltdown in the last year of the George W. Bush presidency. Again, I’m not smart enough to know how much of this was Bush’s “fault.” But he had been in office for six years when the trouble started. So, if it’s ever reasonable to hold a president accountable for the performance of the economy, the timeline is bad for Bush. GDP growth went negative. Job growth fell sharply and then went negative. Median household income shrank. The Dow Jones Industrial Average dropped by more than 5,000 points! U.S. manufacturing output plunged, as did average home values, as did average hourly wages, as did measures of consumer confidence and most other indicators of economic health. (Backup for that is contained in the Post piece I linked to above.) Barack Obama inherited that mess of falling numbers, which continued during his first year in office, 2009, as he put in place policies designed to turn it around. By 2010, Obama’s second year, pretty much all of the negative numbers had turned positive. By the time Obama was up for reelection in 2012, all of them were headed in the right direction, which is certainly among the reasons voters gave him a second term by a solid (not landslide) margin. Basically, all of those good numbers continued throughout the second Obama term. The U.S. GDP, probably the single best measure of how the economy is doing, grew by 2.9 percent in 2015, which was Obama’s seventh year in office and was the best GDP growth number since before the crash of the late Bush years. GDP growth slowed to 1.6 percent in 2016, which may have been among the indicators that supported Trump’s campaign-year argument that everything was going to hell and only he could fix it. During the first year of Trump, GDP growth grew to 2.4 percent, which is decent but not great and anyway, a reasonable person would acknowledge that — to the degree that economic performance is to the credit or blame of the president — the performance in the first year of a new president is a mixture of the old and new policies. In Trump’s second year, 2018, the GDP grew 2.9 percent, equaling Obama’s best year, and so far in 2019, the growth rate has fallen to 2.1 percent, a mediocre number and a decline for which Trump presumably accepts no responsibility and blames either Nancy Pelosi, Ilhan Omar or, if he can swing it, Barack Obama. I suppose it’s natural for a president to want to take credit for everything good that happens on his (or someday her) watch, but not the blame for anything bad. Trump is more blatant about this than most. If we judge by his bad but remarkably steady approval ratings (today, according to the average maintained by 538.com, it’s 41.9 approval/ 53.7 disapproval) the pretty-good economy is not winning him new supporters, nor is his constant exaggeration of his accomplishments costing him many old ones). I already offered it above, but the full Washington Post workup of these numbers, and commentary/explanation by economics correspondent Heather Long, are here. On a related matter, if you care about what used to be called fiscal conservatism, which is the belief that federal debt and deficit matter, here’s a New York Times analysis, based on Congressional Budget Office data, suggesting that the annual budget deficit (that’s the amount the government borrows every year reflecting that amount by which federal spending exceeds revenues) which fell steadily during the Obama years, from a peak of $1.4 trillion at the beginning of the Obama administration, to $585 billion in 2016 (Obama’s last year in office), will be back up to $960 billion this fiscal year, and back over $1 trillion in 2020. (Here’s the New York Times piece detailing those numbers.) Trump is currently floating various tax cuts for the rich and the poor that will presumably worsen those projections, if passed. As the Times piece reported:
