I was almost right, as sad as I am to say it. My prediction was 245,000-255,000. Much closer than the people thinking 200-210,000.

Are you trying to set up for solo or pooled mining? For solo you need to start the bitcoin client as a server.
I've just come back to say I've solved it and found this had been posted! This was the problem. Thank you to everyone anyway for your prompt responses. Incase anyone reading this has a similar problem. Dont open bitcoin seperately. There is an option in the guiminer under the solo utilities heading to "launch bitcoin client as a server. solo will take forever on that card, a pool would be a better option |

Its funny you say that. After posting this thread I did some more research and found and installed the gui miner.
I'm now stuck with that too. I've followed the instructions on the website but when I try to connect I get the message: problems communicating with bitcoin rpc.
I've opened port 8332 and allowed bitcoin .exe and gui miner through my firewall.
I get the same message when trying to do solo mining or pooled mining.
I've self taught my self everything I know about computers with the power of google but this one has me stumped. Any ideas anyone?
You need to port forward 8333 to the computer hosting the bitcoin software. You don't need to open 8332 for the clients, they run off nat just fine. What are the settings that you're putting into guiminer to connect to which pool? |

Someone has probably tried it somewhere. You would definitely need about 2000 watts between at least 2 power supplies since overclocked they pull close to 400 watts a piece |

I am running Windows 7.
I am planning to run 10 Machines each with 2 x 6990 cards in them. So that's a total of 13ghash/s. I want to know how to set everything up to mine to 1 single wallet. I read another thread that if I don't set it up that way they will be mining and competing against each other. Any help is appreciated. Thanks guys. Again, I will donate to you for your help.
You could install the bitcoin software on your Windows box and configure it to talk to the Bitcoin network be a server for all the other boxes. Then for every 6990 you have to run 2 clients and you set then up to talk to the bitcoin server on the Windows machine. The cards don't compete with each other. They each get their own work to work on to try to solve a hash that generates a block of coins. |

When I was at 600 Mh/s I spent a lot of time at deepbit. Since I've added some more speed to my rig and deepbit took off I decided to move to smaller pools. Interface: I like having a website so that I can check my progress (shares and rewards) and the pools progress (speed and solved blocks) from a web browser, i.e. phone and ipod. Speed: I personally like being in a pool above 40 Gh/s because it gives me an acceptable return relative to my rig speed, and the higher the speed, the less solved blocks variate. Fees: Less would be better, but I don't mind giving a little for a nice functional site. I'm liking http://www.btcguild.com/ right now. |

Also assuming the motivation for such attack would be economical is a weakness too.
Suppose the US decide to get rid of bitcoin. They only need to put CIA to DDoS the 3 pools, and Roadrunner to create a chain split that make business unreliable (if not outright seemly fraudulent), as soon people start to mistrust each other unti they figure what is going on, not only the bitcoin market will crash, but people will freak out, and stop using BTC, in a worry that it will happen again, and after that we will have the issue of merging the chains again or rolling back everything or something like that.
People that assume someone will attack the network to doublespend are naive, at best. Or so greedy that they can only think in greedy terms.
The US government would be more inclined to listen in on the network and watch transactions or just find where the pools are hosted and raid them, including Great Britain, Canada, and any other friendly countries. From there they would find out who was making the most amount of money and trace them back by IP wherever possible within their jurisdiction and build an income tax fraud case against them. This wouldn't happen for a few years though since coins didn't have much value this tax season, not many people could say they actually made a profit. No government has been able to shut down Bittorrent. They raid and seize servers that are hosting pirated movie, music, games, software, etc. but they haven't stopped it from existing. It's just psychological warfare to make people think twice before pirating. The only time they manage to take down a network is when it has a central point like Napster and Limewire. To think that any government or treasury would bother with bitcoin anytime in the near future seems pretty far fetched to me. There's only 6.245 million in existence at a peak ( ~8.00 ) value of about US $50 million. Two things: First, the US government attack is a example of non-economical attack. Second, as you said yourself, the time to take down a network is if it has a central point, and deepbit is becoming one, take down deepbit, take down BTC with it. Your example is a poor example then. Everything is the US is about money one way or the other. Whether it's businesses supposedly being harmed by piracy or possibly losing tax revenue. The US Government doesn't care where your money comes from (as long as it's legal, and even then sometimes they don't care) as long as they get their share of it. Bitcoin is not going to be confused with US currency like the case with the Liberty Dollar. Pools are not a central entities. deepbit is not Bitcoin, it is a large entity on the Bitcoin network. Bitcoin will NOT die if deepbit goes down, or even if deepbit and slush both went down at the same time. People would probably freak out, but they can go to other pools or mine solo. Napster was killed because the company was the network, they hosted the servers. They killed the company and killed the network at the same time. That's not the way Bitcoin works. |

obviously the solution here.. isnt necessarily that tycho's pool should be smaller.. its that it should be more reliable and spread out. say 10 pools, each one hosted in a different country on a different server... :p take out one, you only take out 10% of his total.
just telling him to shrink his pool isnt going to be effective.
Yeah, he should up his fee to 7.5% to help pay for all that too. |

I think GUIminer has an option to run on startup. You just need to figure out what --device and --platform options you need for poclbm.

Does this try to use the opencl interface in Firefox 4, Chrome, and IE9 or is it strictly CPU?

I "bricked" my cards a few times while trying out different BIOS's on them. Put a cheap PCI card in the PCI slot closest to the CPU, go into the BIOS and change primary video to PCI and set bootable flash drive to primary hard drive. Boot dos from bootable flash drive and flash cards with working BIOS. Reboot, change primary video option back to Auto. Boot and try again.

If you're worried about having parts just laying around loose why not get just a motherboard tray instead of a whole case.

The idea Tycho would do something with his 'powers' as soon as his pool reaches 50% is just simply stupid.
Currently (in the current market) the guy makes 1000 - 1300$ PER DAY , that is 30k to 39k PER MONTH. In untaxed money even.
He would be stupid to do anything to destabilize the bitcoin market.
The idea that his pool is too large is not stupid, it is a valid concern. If you are worried about the security of bitcoin you should try to not put such a large area of trust in anyone's hands. While I agree it is not in Tycho's interest to do anything bad and really doubt he would..... an intrusion (attack) into his systems (online or physical) could effect the network. So someone get's into his network. Say they manage to take every coin in the system and send it to themselves. Say they even manage to wipe out the logs files so it can't be tracked. It would still show in the block chain. If the pool operators didn't notice it, the users surely would when they weren't getting payouts, and pretty quickly inform the pool operators. Worst case scenario they halt all mining and go into investigation mode. People see that the pool is inaccessible and go elsewhere just like they did when slush's pool went down. There's a very limited time window for an attack like that. A more sophisticated approach would be to redirect the last 2 or 3 digits of the balance, but since people with updated clients can see that and all transactions are public it would be found out eventually. Sure people would freak out, but the network would endure. |

This has potential to decrease barrier of entry into double spending biz significantly, at least temporarily. This is a valid attack vector. Take down major miners and pools with DDOS, than deploy your hashing capacity and do whatever a short term 50% attack allows you.
Better start thinking about network resiliency now.
On the other hand, any such attack will only generate another wave of publicity for bitcoin.
Someone would either already have to have a LOT of coins, buy up a lot of them at the market, or investing in a lot hardware to get enough coins to make an attack like that worth it. They would have to accurately predict what the network hash speed after said take down would be and have more than that running. I doubt DDos could do it effectively, it would have to be a more sophisticated attack than that on all pools are the same time and something to leave them offline for an extended period of time. Compound that by pools starting to have backups on different continents now. After all is said and done, someone might try this just so they can double spend what? 100,000? 200,000? 250,000 BTC? Confidence would definitely take a hit and value would definitely plummet for sure. At best they would be getting their almost worthless coins back. It sounds more far fetched and much harder than pool operators conspiring to pull double spend attacks. I agree it would be great publicity, especially when the network survived. BTC might be back to $US0.25 per BTC, but it would survive like it was designed to do. |

If any sort of takeover happens, I can garuantee you Bitcoins will be almost worthless faster than you could react and will have a very hard time ever recovering.
People will never value a currency that can be taken down this easily. No value, no currency.
Currency exists on trust, value is secondary. Everyone seemed to trust it enough to to be making businesses exchanging it for cash back when it was US$0.80 per BTC when I first started using Bitcoin. The fact that it floats between US$7-8 per BTC is nice, but if you're only worried about it's value then apparently that's all you're into it for. Every currencies value fluctuates all the time, there is no question that Bitcoins will be minted in the future and there will be a finite amount of coins in the end. I trust that more than the US printing more money. |

Lots of people are MISSING THE GODAMN POINT.
With 3 pools having way more than 50% of power (this already happens), WE DO NOT NEED THE POOL OPERATORS TO DO SHIT, WE ONLY NEED SOMEONE TO DDOS THEM TO HAVE BITCOIN FAIL.
You people understood now?
Ok, I already wrote that before and it do not worked.
WE DO NOT NEED THE POOL OPERATORS TO DO SHIT, WE ONLY NEED SOMEONE TO SOMEHOW SHUT THEM DOWN AT THE SAME TIME TO MAKE BITCOIN FAIL.
I hope now people understand better the risk of the 3 pools with more than 50%
Bitcoin doesn't fail because the pools go down. There's still at least 1/4-1/3 of the network out there working solo and as soon as people see that the pools are down all the technical users will switch to solo and the semi-technical will be looking for information on how to go solo. The network will most likey be back to at least half speed in 6-8 hours at the most. That's a far cry from total failure! And since both slush and bitcoinpool have both publicly acknowledged being ddos'd and they're stlll surviving it would take a lot more than that. |

So what? There are lots of entities that would like to endanger Bitcoin and they would certainly bribe/infiltrate with money that would let your figures look like peanuts. But yeah, let’s just wait until this happens and trust in Bitcoin vanishes in an instant. As long as you can get USD for your Bitcoins everything’s fine. Yes, there's a long theoretical list of people who might like to endanger Bitcoin. If any one of them have that much cash available to them then they can also build a super cluster and/or manipulate/corner the market. Both can be accomplished pretty easily and with relative anonymity for someone with said amount of cash. Trust would only vanish for people who are only worried about getting USD for their Bitcoins. |

Except the community is the one causing the "problem". It's not Tyco's or Slush's fault that a majority of people are using their services! It's pretty basic nature that most people want to be part of the largest group. So far the only "do something" I have seen is to ask them to limit their member, to which I would say no if I were them. Again, this is the 3rd time I have seen the argument that they need to be regulated when people are going to them freely. The only thing that can be done it to ask/motivate miners to diversify themselves. The only way to reach them all is for the pool to disappear since some percentage of them probably don't use the forums let alone live on them. It's also not very productive to try to get people to diversify in threads like this that start out dramatic, post incorrect information, and degenerate into flaming and conspiracy.
The basis of bitcoin is a free (as in open) currency and economy, even down to the code. I'm shocked! ShOcKeD! I tell you that free market principles have sprung up. Simple stuff like, providing the best service for an acceptble fee for example. Who would have though?!
Well yes, the community is the 'problem', but only out of ignorance. An astounding amount of deepbit pool users that I've chatted to don't even know how to edit their bitcoin.conf to solo mine. Once they become cognisant of the fact that distributed pools are probably a lot better (or neutral) for themselves profit-wise (and for the well-being of bitcoin's longevity and security in general), we will probably see a change. Once setting up a pool becomes easy/straightforward for users with little technical knowledge, the numbers in these huge pools will likely diminish or at least stop increasing at the rates they are. > An astounding amount of deepbit pool users that I've chatted to don't even know how to edit their bitcoin.conf to solo mine. An astounding amount probably don't care and aren't willing to learn how to do it as long as they are making money in the pool they are at. Unless you want to manage a bunch of people's setups manually a lot of them are probably better off left there until they come looking for the information. It depends on how they were introduced to bitcoin. Some probably got some very specific instructions on how to set it up, some got it set up for them, some set it up themselves but don't know or care about anything past that, then there's the ones who actually know more about it overall and willing and capable to learn more. > Once setting up a pool becomes easy/straightforward for users with little technical knowledge, No matter how easy you try to make something it will be too much for some people. No matter how idiot proof you make something they will always make a better idiot. There's only so far you can go to make it easy for the non technical that don't want to learn. |
