Bitcoin Forum

Hi,

I work in a Call Center as the TI admin.

These machines stay turned on from 23h to 8am just with screen saver. So I´d like to let them mining during this time.

As the computers r not very good to fight against ASICs miners to get Bitcoins, I have some questions:

 1) I think that should be better work with script coins. Am i right?

 2) If so, what coin (in your opinion) I should start mining?

 3) And what is the best software do mining the coin you suggested? (cpuminer, bfgminer, cgminer, etc...)

 4) I am working in a linux to be the pool server (P2Pool). Do you suggest another? (Windows / Linux)

I´m not english speaker, so I have some dificulties to understand ALL the details about cryptocurrency, but I am studying and count on you to help!

Thanks in advance!

Best regards!

If there are no GPU's you should check out some CPU only coins. Quark or the newly announced Memory coin.

you will need to try your luck with CPU mining..

stuff like quark, memory, frozen and prime...

Google and find out what you can

I got to ask, wouldn't this be illegal? using company resources for personal use?

Then again, idk what your companies policies are. You could just be fine?

He is the admin, I'm sure it's all right...  ;)

I would recommend this site, it's a lot easier than mining for cryptos.

http://cloud.mql5.com/

Pays with paypal or webmoney. It's been paying me for years....

I've got payment proof on my site, see signature.

It is stealing of electricity and installing unwanted programs, so definitively good reason to get fired

Let's just assume it's ok... the thread isn't about him asking if he could get fired for this.

Did you know these programs are flagged as malware with antivirus software?

I think hes lying and wants to mine with a botnet  ;D ;D :D  8)

Make sure that you have access to the Antivirus Console server. Then add the folder you put the miners into to the exception list. Also, in group policies add the firewall rules for your miners.

Hi! tks for answering!!

The GPUs are poor.. .like Intel HD 3000 on board.

I´m watching Quark ... Will check Memory Coin!

Tks!!

If you are new to this all together I suggest you sell your coins on BTER if possible. Crypsty just has too many problems.

Referral link: https://bter.com/ref/29371

Referrals get 10% off their fees for 6 months on BTER.

Also once you trade into bitcoin gyft is great if you are cool with having giftcards for your coins.

Memory coin has been having some mining issues, but quark should be mineable for you without difficulty.

Hi! I´m having some dificulties to answer...lol

The site ins´t alowing me to post too fast...

Well.. we are in Brazil ... my father is the owner.

He and me wants to bet in a new business... Cryptocurrencies appear to be a nice issue....

We are still learning...

Thanks for your worries about the legallity.

We will watch for the electricity bill in order to track if worth or not.

Tks!

this will not end well

I think if he'd have a botnet, that would give out impression that he is well versed in this 'scene' and would not ask such simple questions.

There´s no problem with virus or bots here. I can install everything I want.. since it doesn´t disturb the attendants while working.

This is why I have to get all doubts solved. There are almost 100 computers to be configured!!...lol

I must have a "pack" of programs: miner + scheduler + all information ready.

With this in hands, I can install in each computer.

Can you imagine if I have to change some configuration after everything ready? OMG!!...lol

Thanks for your help!!!

Hi Manobra,

Since the 93 computers do not have good graphics cards you will need to mine with the CPU. Use cpuminer for that. Also, you should set up one of the computers as a stratum mining proxy. Find a scrypt altcoin pool to join and set up a unique username and password for each miner, this will take a while since you have so many computers. Then point your proxy at the pool and point your miners at your stratum proxy. Even if the version of cpuminer you use supports stratum I think it's still a good idea to run your own stratum proxy. This allows you the flexibility of changing pools quickly. Instead of changing each individual miner, you can just point your proxy to the new pool.

You may also want to check with the pool admin first and make sure they allow that many workers. Some pools may suspect you of running a botnet. I use wemineltc.com and I believe they allow up to 100 but will allow more if you put in a request. 

I think you should stay away from mining any sha256 coins and stick with scrypt but that's just my opinion. I suggest trying a few different coins and stick with what you like.

Noted! Thank you very much! This is the "way" I was looking for....

.... Scrypt + cpuminer + (join a pool) or (make my own pool) + (try these coins: Quark, Memory, etc...)

Regarding joining a pool and have to contact them in order to let my 100 worlers, what about my own pool?

I think I misunderstood the issue: "pool server"...

I´ve downloaded P2Pool (and many others), tried to configure ... I made cgminer to connect to it, but no hashrate (0.0Kh/s).

Now you said: "make my own proxy server" and after "will be easy to change from pool" that lead me to think that I can´t have my "own private pool", I can only have a "proxy" to centralize the miners and point it to a pool.

Could you please just try to clarify me this point?

Thanks again!!

I´m almost there!! (I think!!)

I don't think starting your own pool would be a good way to do this.

Have you made any calculations? It depends a little on which i7 you have, but since I don't expect your employer to buy computers with high end CPU's (actually the fact you have i7's is already quite rare, you see i5's or even i3's way more often), lets say you can get ~35kh/s per CPU. That would set your total hashrate at ~3255kh/s, which is quite a nice hashrate, comparable to around 3x 7990 GPU. But, most pools are in the order of several hundred mh/s, and you only get 3.3mh/s.

Since the chance of finding a block is highly correlated with the total hashrate of a pool, I think it would be much better to join an existing pool.

Having that said, the suggestion of Jothand is actually a great way to do this. Set up your own pc as a stratum proxy, and have all the other pc's point at your proxy. If you want to switch pool/coin, you will only have to change the setting on your own computer, and all others will automatically work for that pool.

Apart from mining CPU coins like quark, you could definitely also look at some scrypt coins. Since you don't have to pay power, you could even mine LTC, which would still give you around 1LTC per day at the current difficulty. It may also be worth keeping an eye on this subforum, and mine some of the newly launched coins. At the start of a coin you can easily get huge amounts in a short time frame, which could become a lot more valuable in the future (but this is a gamble of course).

Hmmm... Tks too much!

The i7s (actually only 80 are i7) have 8 cores each (made on 2012). The other 13 computers are mixed (2 quad core, 2 core 2 duo, etc...)....

Yes.. we´re a little afraid because of the electricity bill. But we still want to "see for believe" and maybe make some adjusts to make it be profitable.

No, we dont planing to buy more computers. I convinced my father (owner here), that we could use these computer out working time.

I as far as I could see, LTC have already reached a dificulty level that my computers cant compete with.

Maybe after all working, I can measure my scrypt rate power and point to another coin.... I still didn´t got to connect to my server (P2Pool). ahahahahah!!  it says "connected to 192.168.1.254" but 0.0Kh/s.

But the most important information now, is that I have to confifgure my stratum server and configure all computers to connect to it. So I configure this stratum server to use some pool.

OMG! I almost understanding 100% ... what a weight out of my back!..lol

Tonight I will dive in this issue again and maybe sleep here until make it work!!

Thanks again!!

I agree with maardein on this one. Starting your own pool will be more trouble then it's worth.

Here's a link to the getting started page at wemineltc.com
https://www.wemineltc.com/gettingstarted

It's a great LTC pool if you decide to mine LTC. This link has some great "getting started" info that can be altered for whatever pool you decide to join. It also has download link for a stratum miner with some basic info on how to use it.

Well, yes if you calculate power costs LTC is not worth it at the current exchange rates. But I thought you didn't have to pay for power ;)

If you include power costs, your best option would indeed be to mine CPU only coins. Or, like I said before, mine new scrypt coins right after launch for +/- 2 days, get a lot of coins, and hope the value will rise. This is a bit more gambling, since most new coins barely have any value when they start.

Anyway, good luck with setting things up!

Nice! Thanks!

I´m reading the wemineltc "getting started".. but even downloading cgminer under 3.5 (and newer too), gives the error about opencl.dll (this is not a problem.. i´ll check how to download this file), I tried the cgminer-nogpu.exe but says "--scrypt command not recognized..."

So have to solve the DLL problem.

cgminer have a config file that i can reproduce on all my computers. So, I´m thinking in mapp a drive letter (i.e. Z:) in all computers, where Z: = \192.168.1.254\cgminer\" so everybody will use the same .config file (don´t know if it is possible.. i´ll try and make some tests....)

QUESTION: Does it have a problem because too many computers with low hash rate? I read something about errors and loses...

... as much as I understand about this, more I know I´m far to understand everything.. lol!

Thanks again!

If you are going to use the CPU's do not use cgminer! Use Pooler's CPU miner! Works much better/faster.

I´ve realized that right now!

And Pooler´s CPU miner have the 64 bit version! much better!

Thanks!

Please be aware that mining on both cpu and video card  decreases the life of hardware. In the best interest of your company, you might consider not wasting all of that energy mining shit coins.

hey.. I'd buy some 7970's or 280'x and convert your callcenter to a dark inferno  8) you dont need to have 3 gpus per one machine... one would be good enough ;)

people will not notice a thing that their computers gets raped overnight  ;D just tell them to open the windows in the morning.

good luck!

93 gpus could give you ~70MH for GPU mining.

Proceed with caution...  People have been fired for running BOINC / Seti@Home on work computers.

In those cases, the people weren't profiting - I suspect the consequences could be even higher if you are putting software on them to make $$$.

There are other examples - those are just the first two I found.  And yes, they were not very smart about it.  At very least, make sure the powers that be know what you are up to - it's nice to have extra coinage, but probably not worth risking a career over.

Best CPUMiner for quarkcoin.
i3i5i7_Improved2 best hash

Why in the world does a call centre operator need a machine with an i7 in it? Pure overkill!

Focus on being a call centre operation first and not a mining operation.

Seems like a few fundamentals need going over here.

Using it!

Thanks!

They r old i7 (first or second generation). 2630QM

They already have 2 years... time to push them to its maximum power!




If ppl just try to help ... forum would be more clean... (bla.. bla.. bla.... energy... bla bla bla .. overkill... bla bla bla... will be fired.... lol)

DON´T LOSE THE FOCUS... READ THE TITLE AND PLEASE.. TRY TO HELP.. NOT TO MAKE POINTS IN FORUM.. TKS!

TKS FOR EVERYBODY THAT HELPED ME!

My friend is interested in mining quark with some i7 pc's he has access to.
I did a little research, but could not find anything like btc-ltc mining hardware comparison chart for cpus.

How much kh/s are you getting per cpu?
How much should ivy bridge i7 get?

Also - is there a profit calculator for quarkcoin / other cpu currencies?

+1

I have a shitload of high-end enterprise hardware under my control but I'm not going to risk my job running them as CPU miners.
YOU WILL GET FIRED!! The powerconsumption of your systems will skyrocket and they will find out.

Hi!

You have almost the same scenario than me.

I´m getting like 30/35 Kh/s (per computer) when using all cores (8 cores each CPU) - only 5Kh per core) - Mining Quark!!

I didnt find any specific Quark calculator... but u can use some genereic calculator and fill with information like dificulty, etc... (i actually dont know how to do this... but it´s the way...)

Almost 100 computers, but still no coin!!! lol

2 days running and watching to see if i have some coin in my addres, but none..lol

BASIC QUESTION: How can I check if my quark address have some coin? I´m using http://block.lowend.fm/address/QQ1Fnz5bWmibxaKmQ8fNoGTT4tTJHjbAyd

but it says my address have not seen on the network.. Am I mining for someone else? ahahaha!!

Good Luck!

Are you trying to mine solo? If so, you must be very lucky to find a block. Try a mining pool.

You're right - the legitimate suggestion that you are most likely jeopardizing your career and livelihood is not helpful at all.  I should stay on topic, I'm so sorry.  I look forward to hearing about how well this goes for you.  Please report back in a couple of months on how it all worked out.

Relax, his dad is the owner of the company, and he has got permission to experiment with mining.
