The OP is broken (at least in my browser), all images lost ....

Yes should have of course, it was on one of my miners and I did not have access to it when I wrote. However, now its solved, really stupid. The .bat was a .sh  which came from a Linux box which I started to edit  and I was playing with a Win7 machine => wrong line breaks => all crap in windows cmd ...

Thanks for the reply

I have been trying to use Ethermine with Claymore dual 4.7, with no luck. There is probably something obvious I am missing.

1) When I use the supplies start.bat, it starts and submits shares, if I add a worker (test123), the worker shows up in stats.

2) When I change Eth-address in startup.bat to my own, I get error message that dev fee is not supported on pool and that I have to use the -allpools 1 switch.

3) When I ad the -allpools 1 switch to my bat I get only rejected shares from pool and my worker never shows up.

Is the ethermine pool no longer supported, although the OP says so? Anyone who get this working with 4.7 and can share their .bat?

I am currently on miningpoolhub, but I get rather low payout, and my miners keep disconnecting and reconnecting. I think this messes up the difficulty or something, cause I am getting low yields, or simply the downtime is the problem. Is it only me having problem with miningpoolhub?

Thx

From the image you seem it looks that you are mining fine. You are submitting deadlines, so that is good. The failed info line is just saying that your miner did not get a conformation for whom (i.e. that URL you have in in you miner.conf under get mining info) you set to inform you who solved a certain block and also the network size and possibly some other info.

As far as I understand this does not affect your mining

It's difficult to quantify the value of reading through the Plots faster, but my feeling is that every second counts, particularly on any Block that is found in under a minute. I have got rid of my Hub as that was slowing things compared to USB drives plugged straight to the mainboard and have also added a USB controller with 4 dedicated 5Gbps channels for the rest.

The main 36TB now is read in 9 Seconds and I am sure it has increased the amount of Burst I am earning. Only trouble is that it's expensive to have a dedicated channel for each USB drive...

36 Tb in 9 seconds is very fast, guess these are optimized plots? I am currently optimizing my plots on the main host (a Semi professional QNAP, NAS which has 43 Tb) and it currently takes 45 seconds (un-optimized plots) so nowhere near your speed. I don't think that hardware is rate limiting, it has a dual GB connection (trunked) and it reads to my workstation with 235 MB / s (close to the 2 Gbit it should have). The other drives are more of a problem, some reside in old DLINK NAS units which reads at best 15 MB / s. Those that are hooked up directly to internal SATA channels are fine (Seconds to read) but one computer has 12 drives hooked up. I don't know how the threading works in the miner (Blagos miner), but it seems that some are read very late. The CPU on that machine is a 2 core i3 so it does not handle threads well.

I did not realize this was a major problem, but I will try to optimize the hardware. Do you have any feeling if internet connection could be limiting (I am on a slow DSL (8 mbit) connection, which is stable but latencies are probably terrible.

I can maybe have a little input on the 23 blocks on the same file if it's the same I've noticed with mine. I've swapped drives and replotted many of them starting from scratch a few times, from nonce 0 I mean. Upon replotting a drive from zero nonce months after starting to mine burst I was checking a couple new plots for overlaps. It showed that they had found blocks already but they were new plots but were do overs if u will. The blocks were found using older drives but with similar plot ranges, I had just altered the ranges due to using bigger drives. Hope that maybe makes sense, best way I can explain it.
[/quote]

That makes complete sense, I should have realized this. I have been mining burst for almost two years and made new plots several times, but with the same logic on how to organize plots. Therefore, some plots might be in the same scope as the new ones, and I never changed my account, so the system can not know if it is the current or a deleted plot that did find the  block. I am sure that is the case, but I don't have the info to backtrack it.

Always nice with smart persons

Thanks

I just noticed one strange thing on my blocks. The webtool to check if plots overlaps also lists how many blocks a certain plotfile has found. In my case most plot files (=ranges) had 1 a few had 2 or 3 (some 0) and one has 23. Those plots are all 1.3 Tb in size. I wonder what the likely hood of this (its to late to calculate this now) is?

- I have 53 Plotfiles the same size.
-146 blocks found.
- 23 Blocks on the same file

I wish that unequal distribution in this world of randomness could have been used on something else (like increasing the number of blocks I find!). I guess the hits should be randomly distributed?

Just to follow up on this. I switched my machines to solo mining, exactly one on week ago. I have since then on 72.2 Tb of non overlapping plots (calculated that exactly) and mined 51'898 BURST during this week. According to the mining calculator at

http://burstcoin.biz/calculator

this should have given me 78'734 Burst meaning that either I am unlucky (likely I guess, fits with other aspects of life :-)), the calculator is off (?) or there is something wrong with my set up (could my drives be to slow, or my ISP connection?). The drives are mainly scrap that I found, most are mounted in random, old, USB2 cases, some directly to SATA ports and some in old NAS cases (All with gigabit connections, hooked up to a good HP switch, so that should no be the a bottleneck). My ISP is 8 Mbit down 1 Mbit up.

It still pays better then last week of pool mining, so I let it go for another week to see if my luck changes. Any thoughts on if my setup could be too slow is really appreciated.

/

I am not sure if it is a good idea to submit deadlines from different miner instances for one account since higher deadlines may cause a penalty on pool side if one of the other miners already submitted a lower deadline.

anyone knows if there exists some sort of proxy for such setups?

if there exists none a total capacity above 50 tb should also be fine to mine solo with.



[/quote]

A proxy would be the best solution. Isn't all communications with pool through https? Couldn't I use a standard webproxy for this, as long as I can set any port number in the proxy, or are there reasons this won't work.

I could probably try with solo mining, but there must be the same problem with different machines? Or is it so that the likelihood for a "hit" will just be proportional to the amount of plots I have in total regardless on which machine they are on?

I am just a little concerned regarding the bandwidth issue. I need to have a wallet running on each machine, and does that take a lot of bandwidth? Anyone knows how much it consumes regarding bandwidth?

Thank you for the input.

There is this calculator tool you can use

http://burstcoin.biz/calculator

Just remember that this is theoretical average per day. For a single day it can vary a lot. Also, don't know how accurate this calculator is, I know I don't reach the expected number of coins, but that could be due to my other issues.

I use the GPU plotter for plotting and I calculate range for the plots manually, I hope I did this correctly, but when I check overlaps with the plotter it shows no overlap. Hopefully that part should be fine at least.

Thanks for all answers I am using Blagos miner and my plots do not overlap. I actually did a test. I had originally a NAS with 4 Tb attached to the 53 Tb machine (It was 57 Tb at that point) and "moved" I to one of the other machines. Size reported in pool went from 57 Tb to 53 Tb at that point. So pool does only "report" the largest. Question is if it is mining and becoming a part share calculation (I suspect not, since my payouts are to low, but that is only measured for a few days and I can obviously be different between days). I see all three machines submitting deadlines (according to miner).

/Thx

I just noticed something, perhaps this is obvious and just me who don't understand how this works. I have plots on three machines (53 Tb + 10 Tb + 12 Tb). All plots are generated for the same account. Each machine runs a miner and all three miners are pointed at burst.ninja, but in the pool, I only see 53 Tb as ~capacity. Are the other two machines not mining, or is it just the pool which does not show the other two, but they are still being used?

Is there a better way to set this up? The computers (win 7) are physically in different locations so it is not trivial to share drives between them. I could mine with one account for each machine (just set up three burst accounts) but that means I have to replot 22 Tb of plots, which I hope I will not have to do ....

Thx

I throw this question out here in hope of some input, I am totally stuck here ....

I am trying to access the Poloniex tradingApi from JAVA code, and all I get is the error "invalid command". A standalone static (utilities) method that illustrates the problem

public static final long generateNonce(){
      
      Date d = new Date();
      return d.getTime();
   }
   
   public static final String getAddressPoloniex(String currency, double amount, String address) throws IOException{
   
      String result = null;
      String nonce = new BigDecimal(WithdrawUtils.generateNonce()).toString();
      
      String connectionString = "https://poloniex.com/trading?command=returnDepositAddresses&nonce="+nonce;
      
      String hmac512 = MyUtils.hmac512Digest(connectionString, Keys.POLONIEX_SECRET_KEY);
      
      HttpsURLConnection poloniexCon = null;
      
      try {
         poloniexCon = (HttpsURLConnection)new URL(connectionString).openConnection();
         poloniexCon.addRequestProperty("Key", Keys.POLONIEX_API_KEY);
         poloniexCon.addRequestProperty("Sign", hmac512);
      } catch (MalformedURLException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
      } catch (IOException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
      }
      
      try {
         poloniexCon.setRequestMethod("POST");
      } catch (ProtocolException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
      }
      poloniexCon.setRequestProperty("Content-length", String.valueOf(connectionString.length()));
      poloniexCon.setRequestProperty("Content-Type","application/x-www- form-urlencoded");
      poloniexCon.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0;Windows98;DigExt)");
      poloniexCon.setDoInput(true);

      DataInputStream input = new DataInputStream( poloniexCon.getInputStream() );

      StringBuffer s = new StringBuffer();
      for( int c = input.read(); c != -1; c = input.read() ) {
         s.append((char)c);
      }
      
      result = s.toString();
      input.close();
      
      return result; // here result has {"error":"Invalid command."}
   }


This approach works well with for example Bittrex exchange. My feeling is that the problem is in the HMAC SHA512 signing. I do that like this:

   public static String hmac512Digest(String msg, String keyString) {
      String digest = null;
      try {
         SecretKeySpec key = new SecretKeySpec((keyString).getBytes("UTF-8"), "HmacSHA512");
         Mac mac = Mac.getInstance("HmacSHA512");
         mac.init(key);

         byte[] bytes = mac.doFinal(msg.getBytes("ASCII"));

         StringBuffer hash = new StringBuffer();
         for (int i = 0; i < bytes.length; i++) {
            String hex = Integer.toHexString(0xFF & bytes);
            if (hex.length() == 1) {
               hash.append('0');
            }
            hash.append(hex);
         }
         digest = hash.toString();
      } catch (UnsupportedEncodingException e) {
      } catch (InvalidKeyException e) {
      } catch (NoSuchAlgorithmException e) {
      }
      return digest;
   }

If it is not that, I am out of ideas. This HMAC digest works fine with Bittrex. The Poloniex API doc is relatively brief on how this should be calculated. The error is confusing and indicates there is a problem with the command, but all other commands to the trading (private) API gives me the same error. All calls to the public API works fine. I have spent several hours on this now. I know my keys are fine, they work with python code.

The first person with a solution that actually fixes this and send me / post their BTC address will get a 0.1 BTC bounty!

It is actually so that zenhashlets can mine hashcoin (via hashpoints) now and probably for only a few days. Very profitable right now. ~17 hp/mh/day.

Yes, the address is correct. I got my first payments now, all is well. It took an hour for the first to come, although it said confirmed really quickly in the stats.

Thanks

Hi,

I am trying the pool, seems to work fine. Found a few blocks, how are payments handled? I nothing in my wallet yet, is it sent at certain intervals or at a fixed amount?

Thanks

Perhaps also cryptostocks should be reported as well. I don't think I am the only one who had issues with them. Several times it took them a month to remove obvious scams, and never reply to customers. What do you have to do to earn your place at that list?

Actually I fixed it. I switched to Ubuntu 14.04, switched from qmake to make and manually created a /obj directory in the /src folder, cause a missing /src/obj directory was one of the errors qmake spit out. I don't know which of the changes did the trick, but it compiled. 

thanks

Hi,

Anyone been able to compile the latest VMC-source from git on linux? I tried on Ubuntu 13.1, compile failed badly. Seems like files are missing from the source, or is the git link in the OP outdated? 

I tried to compile the vertcoin source on the same machine, which went fine, so I think my environment is sane.

Any help or ideas?
