Pooled/Remote Mining - Open Source - Updated 2010-12-24

[pc]

I'm having a terrible time trying to get this running on my Mac. I think I've complied and installed the Boost library, and installed the CMake and CUDA library, which this seems to need, but I'm still getting the following when I try to make:

It's highly likely that I've screwed something up trying to get this to all work (my guess is Boost), but there's not really much in the way of direction. Can anyone give me a hand? Thanks.

[puddinpop]

puddinpop, when running this latest version I'm always seeing a message on the remote client saying that my address is not found in the block being solved. It doesn't show the share that I'd get that it used to. Is something broken or is there a change in the behaviour?

It will distribute the coins in the block the same as it did before.  If you see the message that the address wasn't found after the client gets its second block, that means something isn't working quite right on the server.  Check the bitcoin log file to see if there are any messages about clients failing metahash verification.  Most likely, if you are compiling the server yourself, you ran into the same issue I have with release builds in Visual Studio.  If this is the case, try to compile without optimizations turned on.

I've tested with the binaries that I've uploaded, and I can confirm that they are working as they should be.

There are no failed hashes in the log. But there only seems to be one client passing: If I grep the log for "passed metahash" all I see is one client IP address listed. There are 16 clients connected to the server.

Hi puddinpop,

what's the status of your OpenCL implementation atm? I see you have begun a implementation although it is disabled currently.

[BitLex]

the remotminer-cuda.exe seems to work already,
although it's still slower than standalone-versions.

on my GTX260 i get
standalone ~45M
remote-cuda ~17M

hopefully the "Address ... not found in block solved" thingie doesnt cause any bigger problems


update: i just noticed that the remote-cuda.exe also has ~50% CPU usage, that's unpleasant.

[doublec]

There might be some server up and down-age as I add some debugging to investigate this. Clients should reconnect gracefully. Don't panic if you see it

[doublec]

puddinpop, there appears to be no call to SetLastVerifiedMetaHash in the current code, whereas there is in the last version. Is this a bug?

[inertia]

That was graceful.  Nice!

[doublec]

I added a call to SetLastVerifiedMetaHash but that didn't fix the issue for the contributed distributed type. So I've switched back to 'connected' and this displays the address as being in the pool.

I'll switch back to 'contributed' if the issue is resolved.

Imagine there were multiple servers running the contributed method. Wouldn't the optimal thing for a miner to do to be to continually jump to the server that had most recently generated since the same power will be worth more there since you are sharing with fewer previous work units?

[FairUser]

Q: How would one go about running their own mining server?

I read the readme and tried to setup my own mining server, but it doesn't seem to be acting like a server.  I tried the "-remoteserver" flag, but it doesn't take it.

Could someone please provide an example of what command and options I would use to start a mining server?
Also an example of the what client's would have to run to connect to my server.

Thanks!

I'm also having issues building on Debian (Lenny).

Any ideas?

[doublec]

Could someone please provide an example of what command and options I would use to start a mining server?
Also an example of the what client's would have to run to connect to my server.

To run a server on linux:

Code:

bitcoind -remoteserver -remotebindaddr=0.0.0.0 -remotebindport=8335 -gen

Note the 'remotebindaddr'. This is what makes the server accessible over the internet by other clients.

To run clients:

Code:

bitcoinr -server=ip.addr.of.server -address=bitcoinaddress

[doublec]

Any ideas?

You should install libboost-all-dev.

[puddinpop]

I've updated the first post with the latest release.  The "contributed" distribution method should be working now.  That is the only substantial change in this release.

[Cdecker]

I've temporarily hacked in a hard coded limit of 102 clients. Any connects after that will fail. Unfortunately no message is printed to the client and it immediately retries but it beats the server crashing.

You could put haproxy [1] in front of both servers so that the less charged one gets new connecting clients and you even have transparent failover :-)

I'm having the same problem compiling on a Mac.  Compiles fine on Linux.

replace src/remote/remotebitcoinheaders.h with http://www.bluishcoder.co.nz/bitcoin-pool/remotebitcoinheaders.h and see how that goes.

Does that also work for running a server on Windows?

Yes, except replace 'bitcoinr' with 'remoteminer-cpu.exe' or 'remoteminer-cuda.exe'.
