Ping

Today, other methods of checking connection speed and quality exist, such as traceroute or pinging other large sites such as google.com or cnn.com, but due to the meme Yahoo has remained popular.
. It caught on, because in early 1990s, Yahoo was the primary hub of useful information and the domain name was already well known, and had a high uptime due to its then-unique use of Akamai load balancing. From the classical political economists to Michal Kalecki it was known that prices for industrial goods behaved differently from prices for agricultural goods, but this idea could be extended further to other broad classes of goods and services. Many Internet Service Provider support technicians and simply tech-savvy individuals recommended pinging yahoo.com, creating this meme. One insight often ignored in the debates about price theory is something that businessmen are keenly aware of: in different markets, prices may not function according to the same principles except in some very abstract (and therefore not very useful) sense. In the early 1990s, many people began to ping yahoo.com when their internet connection seemed slow or dead. Marginalist theory lacked anything like a theory of the social framework of real market functioning, and criticism sparked off by the capital controversy initiated by Piero Sraffa revealed that most of the foundational tenets of the marginalist theory of value either reduced to tautologies, or that the theory was true only if counterfactual conditions applied.

The Windows ping utility returns the same information as the Unix implementations, albeit with different formatting. This would then result in a much more realistic theory of price and of real behaviour in response to prices. On a system with a BSD Unix lineage, ping traditionally only answers whether a host is ”alive” or not, but modern systems may provide a more System V–like output as shown above. Without denying the applicability of the Austrian theory of value as subjective only, within certain contexts of price behaviour, the Polish economist Oskar Lange felt it was necessary to attempt a serious integration of the insights of classical political economy with neo-classical economics. The above sample is typical of ping on an operating system with a UNIX System V lineage. Neoclassical economists sought to clarify choices open to producers and consumers in market situations, and thus "fears that cleavages in the economic structure might be unbridgeable could be suppressed". Below is a sample output where the wikipedia.com server is "pinged":. As William Barber put it, human volition, the human subject, was "brought to the centre of the stage" by marginalist economics, as a bargaining tool.

The output of ping, and its cousins, generally consists of the packet size used, the host queried, the ICMP sequence number, the time to live, and the round-trip delay time, with all times given in milliseconds, and times below 10 milliseconds often having low accuracy. One solution offered to this paradox is through the theory of marginal utility proposed by Carl Menger, the father of the Austrian School of economics. The syntax is "ping -x <input>". Adam Smith described what is now called the Diamond–Water Paradox: diamonds command a higher price than water, yet water is essential for life, while diamonds are merely ornamentation. The following switches are available to expand Ping's usefulness. The last objection is also sometimes interpreted as the paradox of value, which was observed by classical economists. The syntax is "ping -x <input>". Six criticisms Marxian economists make of neoclassical economics are that neoclassical price theory:.

The following switches are available to expand Ping's usefulness. According to Marxian economists, while all labor-products existing in an economy have economic value, only a minority of them have real prices; the majority of goods and assets at any time are not being traded, and they have at best a hypothetical price. Internet worms such as Welchia flooded the Internet with ping requests as they sought to locate new hosts to infect, causing problems to routers across the Internet. Most equilibrium prices are hypothetical prices, which are never realised in reality, and therefore of limited use, although notional prices can influence real economic behaviour. The usefulness of ping in assisting the "diagnosis" of Internet connectivity issues was impaired from late in 2003, when a number of Internet Service Providers filtered out ICMP Type 8 (echo request) messages at their network boundaries. Ideal prices are hypothetical prices which would be realised if certain conditions would apply. Mills provided a backronym, "Packet Internet Grouper (Groper)", also by other people "Packed Internet Gopher", after the small rodents ). Real prices are actual market prices realised in trade.

(Later David L. Marxian economists distinguish very strictly between real prices and ideal prices. He named it after the pulses of sound made by a sonar, since its operation is analogous to active sonar in submarines, in which an operator issues a pulse of energy (a network packet) at the target, which then bounces from the target and is received by the operator. Money prices are merely the most common form of prices. Mike Muuss wrote the program in December, 1983, as a tool to troubleshoot odd behavior on an IP network. However, in an anthropological-historical sense, Marxian economists argue a "price" is not necessarily a sum of money; it could be whatever the owner of a good gets in return, when exchanging that good. . In Marxian economics, the increasing use of prices as a convenient way to measure the economic or trading value of labor-products is explained historically and anthropologically, in terms of the development of the use of money as universal equivalent in economic exchange.

It works by sending ICMP “echo request” packets to the target host and listening for replies (ICMP “echo response” packets). Exchange-value can however also be expressed in trading ratios between quantities of different types of goods. Ping provides estimates of the round-trip time and packet loss rate between hosts. Money-prices are viewed as the monetary expression of exchange-value. It provides a basic test of whether a particular host is operating properly and is reachable on the network from the testing host. In Marxian economics, it is argued that price theory must be firmly grounded in the real history of economic exchange in human societies. Ping is the name of a computer network tool used on TCP/IP networks (such as the Internet). Other stores (such as dollar stores, pound stores, euro stores, 100-yen stores, and so forth) only have a single price point (1$, 1£, 1€, 100¥), though in some cases this may get more than one of some very small items.

-W <timeout> - Time to wait for a response, in seconds. For example, Dollar General is a general store or "five and dime" store that sets price points only at even amounts, such as exactly one, two, three, five, or ten dollars (among others). -w <deadline> - Specify a timeout, in seconds, before ping exits regardless of how many packets have been sent or received. The price of an item is also called the price point, especially where it refers to stores that set a limited number of price points. -V - Show version and exit. From this point of view, a price is similar to an opportunity cost, that is, what must be given up in exchange for the good or service that is being purchased. -v - Verbose output. Prices can also be said to exist in a barter system, although they may not be expressed in money.

-U - Print full user-to-user latency (the old behaviour). Economists, strictly speaking, view price as an exchange ratio between goods which reflects a utility preference by the buyer. -M <hint> - Select Path MTU Discovery strategy. However, in countertrade prices may nevertheless be used to establish trading ratios, and informal bartering continues. -T <timestamp option> - Set special IP timestamp options. Historically, price value has superseded the barter value of pre-monetary systems, in which bartering was used to determine a value of a good or service. -t <ttl> - Set the IP Time to Live. .

-S <sndbuf> - Set socket sndbuf. Price is also central to marketing where it is one of the four variables in the marketing mix that business people use to develop a marketing plan. -s <packetsize> - Specifies the number of data bytes to be sent. The concept of price is central to microeconomics where it is one of the most important variables in resource allocation theory (also called price theory). -r - Bypass the normal routing tables and send directly to a host on an attached interface. In economics and business, the price is the assigned numerical monetary value of a good, service or asset. -R - Record route. Historicalstatistics.org Links to historical statistics on prices.

-q - Quiet output. Wages, Prices & Living Standards: The World-Historical Perspective. -Q <tos> - Set Quality of Service -related bits in ICMP datagrams. Pierre Vilar, A history of gold and money. -p <pattern> - You may specify up to 16 pad bytes to fill out the packet you send. Makoto Itoh & Costas Lapavitsas, Political Economy of Money and Finance. -n - Numeric output only. Simon Clarke, Marx, marginalism, and modern sociology: from Adam Smith to Max Weber (London: The Macmillan Press, Ltd, 1982).

-L - Suppress loopback of multicast packets. Stigler, Theory of Price. -l <preload> - If preload is specified, ping sends that many packets not waiting for reply. George J. -I <interface address> - Set source address to specified interface address. Milton Friedman, Price Theory. -i <interval> - Wait interval seconds between sending each packet. is unable to provide a coherent explanation of the relationship between price and economic value.

-f - Flood ping. disconnects price theory from the real economic history of the use of prices. -F <flow label> - Allocate and set 20 bit flow label on echo request packets. fails to distinguish adequately between actual market prices; administered prices; and ideal, accounting, or hypothetical prices. -d - Set the SO_DEBUG option on the socket being used. assumes equilibrium prices will exist and that markets tend spontaneously to equilibrium prices;. -c <count> - Stop after sending count ECHO_REQUEST packets. simply assumes prices can be attached or imputed to all goods and services;.

-B - Do not allow ping to change source address of probes. is not based on any substantive, realistic theory of economic exchange as a social process, and simply assumes that exchange will occur;. -b - Allow pinging a broadcast address. -A - Adaptive ping. -a - Audible ping.

-w <timeout> - Timeout in milliseconds to wait for each reply. -k <host-list> - Strict source route along host-list. -j <host-list> - Loose source route along host-list. -s <count> - Timestamp for count hops.

-r <count> - Record route for count hops. -v <TOS> - Type Of Service. -i <TTL> - Time To Live. -f - Set Don't Fragment flag in packet.

-l <size> - Send buffer size. -n <count> - Number of echo requests to send. -a - Resolve addresses to hostnames. -t - Ping the specifed host until interrupted.
