I think you'll find that most embedded hardware has your "broken" IP implementation. Probably partly because it's more work to set it up correctly, but also because there are a lot of times where installers in the field or repair people in the shop have no way of knowing what the IP address of this stuff is supposed to be and need to be able to get at it. Devices that I have personally worked with would include a plethora of security cameras, Seimens I/O panels, Lantronix and Mercury TCP/IP to serial I/O converters, AMAG security hardware, two kinds of infant abduction systems, intercoms, and emergency alert systems. Some (most?) SCADA hardware is set up that way as well, I've been told. I suppose the reason why this isn't really considered a security issue is that you need physical access to the device to make it work.

You are a gigantic liar, which became clear as day over the course of this thread. Good luck to you in all your endeavors, liar. A liar lies even as his lies are clearly pointed out.

'Corporations are not and have never created jobs' + 'corporations create jobs because they buy labour'. This is on you, I have nothing to do with it. Production allows consumption, never the other way around. Without production there is no consumption. Production creates the markets. You don't understand that part, fine. That is just economic ignorance and stupidity and likely class warfare, but making opposing statements and denying them outright in the same thread is a clear sign of a liar and I do not waste time on liars.

Inflation is in double digits and nowhere near 0. Of course you can choose to believe government propaganda or you can choose to see reality of 0% interest rates for 6 years but that is your choice.
Inflation is not just bad in a conventional sense, it is absolutely destructive to the economy and thus society. It is what destroyed savings and productivity in the USA and some other countries, it is the actual reason behind the demolition of quality of life of people in the USaa since 1917 ( when the Fed was authorised to monetize government debt).

Inflation is what caused the Great Depression, stagflation of the seventies, collapse in the late nineties, collapse in late 2008, and the current state of destruction of the economy and the impending collapse of the USA bonds and the dollar.

USA is Greece but with a printing press and with what is considered 'the reserve currency'. This allowed the USA to run the scam for much longer than anybody else. This is why the collapse will be so much more spectacular.

The rich should not be forced to do anything by the mob and the state for anybody, they should be left alone to make profits. Profit is what creates the economy. Without profit motive there is no economy. Of course the world lost that understanding, but not everybody. Those who get it are the economy of the world and the funny thing is they are the biggest capitalists and they give communism good name... The USA is a collectivist semi socialist semi fascist state, but it gives capitalism bad name. USA is not a free market society, which is what it should be, why people used to go there. China used to be communist or whatever sollectivism they had and yet they are now the biggest free market there is. Funny how things go and funnier still how blind people like you are.

My problem is oppression by the mob and or state of the individual. Personal charity is personal matter. Nobody should be forced under any circumstances for any reason and for anybody to give up their time and or savings. Anybody can make a case for private charity and people are often generous. Nobody should think they have entitlement for institutional theft and redistribution.

That is a private charity case. Only an idiot like you would fail so bad by appealing tovemotion with me. Policy built on edge case scenario and being forced down everybody's throats is exactly the wrong 'solution', which as I said leads to long term instability and destruction and it is an immoral policy of violence and oppression of the individual by the mob.

As to your case, the violence of the parents in that case is criminal and justice can easily include financial retribution. But all of that is beside the point.

The point is that all edge cases need somebody willing to be charitable and if absolutely nobody is and nobody would help, then the person will be left to fend for him or herself on their own and correctly so. Nobody should be forced by the violence of the state to give up their savings and or time. If the person dies that means that nobody was willing to help and that is a completely acceptable outcome for all involved. The person couldn't make a charitable case and nobody did on their behalf, too bad for them, I guess nobody liked them and nobody had savings to spare, thus the markets are still protected against destruction in the long term and the resources are put to better use.

'We' shouldn't be doing anything. 'We' means oppression and theft. You, as an individual can spend your savings however you want, run your charity all you want. Children should be raised by their parents or somebody feeling charitable to children. You can start and advertise an orphanage, that is your right. Nobody ever should be forced to participate.

Works, I've done it several dozen times. You're communicating at the physical layer. The exception would be if some absolute moron of a programmer hard coded an IP address for the source in the application.

The only one? :) ha! Read my journal and some comments...

Nothing should be done about anything. Failures need to be allowed and nobody should be given any bailout. Not banks, not countries, not businesses and not individuals. All forms of welfare must stop. Economic activity is bring destroyed by inflation (money printing) and by fake centrally planned and controlled interest rates. Free markets are destroyed and this means economies are destroyed. People need to learn within their own means, to spend only what they have and not ge t into debt for consumption and all government debt is consumption debt. Debt for production I'd investment made from real savings of real money, that is not what governments and nations are doing, they are spending other people's money for consumption and there can be no return on any of that, none of it is investment.

Socialism only 'works' as long as the promises of the politicians can be delivered based on stolen (taxed) and borrowed (printed) money. Once that dries up there is no sustainable model for collectivism to survive. It can prolong the suffering with tighter central control and basically slavery and possibly a war for resources but it cannot be sustainable in the long run. Nothing that relies on violence as opposed to voluntary cooperation (free market) has a long term future. So nothing 'should be done', failure must be allowed.

Your words are you think cooperation is better than competition, my answer to it is: OK, but do not even think of forcing cooperation upon me, that will not end well.

Everybody competes. Communism is exactly as evil as fascism since both are collectivism forms that require destruction of the individual freedom, individual choices and individual ownership and operation of property so that the mob is getting the benefits supplied by those who can produce more. The ones producing more are absolutely willing to trade. Trade for the productive output of others and if they want to be charitable it is their choice. But nobody under any circumstances should ever for any reason be forced to support anybody, be forced into any form of collectivism at all, regardless of whatever the intentions may be of the collective. The collective must never be allowed above any individual, that is the point of individual freedom. That is why people ran away from their oppressive governments to the USA. That was what made USA unique.. But today the US is no different and in many cases even worse than many other countries in that respect.

If you want to cooperate with others, you have plenty of ways to do it. Start your own partnership, do whatever you want as a group of like minded individuals.

But that is not your desire. Your desire is not cooperation of like minded individuals. It is oppression of everybody under your favorite form of collectivism. You will never have me join on my own accord, so you want to force me to join so that I can be brought down to your level and oppressed by your violent political structure. The answer is no.

Because the device isn't identified by its IP address at the physical level, but by the MAC address. Your NIC will first do a MAC broadcast to see if the target is on the same network segment. If you use a hub it will be forwarded to all the other ports and the other NIC will answer, if you're on a switch it **should** forward the packet, but sometimes they'll be flaky and ignore a MAC broadcast.

- good.

- good.

- good

- irrelevant.

In fact the syntactic sugar added starting with Java 5 is mostly bad. Generics - bad, horrible code. 'for (blah: type)' - bad, no Iterator access. Autoboxing - horrible, gigantic mistake, etc.

But what do I know, I just end up releasing one working project after another by hiring novices and training them in a month to a level they become to projects.

"for example 172.16.16.20" Example.

The arp command will work with any valid IP address, not just 172.x. I assume that the IP address is not hard coded into the app.

MAC addresses are assigned by NIC manufacturers, not the pump manufacturer (and I'll guarantee that a pump manufacturer has no clue how to build a NIC). Every NIC manufacturer has a set range of MAC addresses assigned to them, and each NIC gets its own unique MAC. I can look at a list of MAC addresses connected to a switch and tell you which devices are Lantronix boxes, which are Axis cameras, and which are Mercury access control panels just by looking at the MAC address ranges in use.
