RPC Miners (CPU/4way/CUDA/OpenCL)

[DrivingVertigo]

I'm getting 0/khashs on the windows binaries you compiled. doesn't matter if it's CPU, CUDA, or screensavers.

If you don't see a line that says "Target = " with something other than all ffs, then the miner couldn't connect to the RPC server and couldn't download work.  Check that your arguments are correct, particularly the login info.

Thanks, that got the wheels turning upstairs.  I had to register a worker first on bitcoin.cz before it would allow me to get work units. I thought that simply signing up for an account was enough. Now I am getting work and hashing roughly 45000 khash/s on my GTX 260.

I compiled the cpu only version of rpcminer on mac osx and it compiled with no problems.  However, it's still only getting 0khash/s.  Is there a way to test it in non-network mode to see if it's just having problems getting data to work on? 

Code:

./rpcminer -url=http://mining.bitcoin.cz:8332 -user=user.1 -pass=pass
Client will start 2 miner threads
Work will be refreshed every 4000 ms
0 khash/s
0 khash/s

I tested minerd just before this and it works great

Code:

./minerd --url=http://mining.bitcoin.cz:8332 --userpass=user.1:pass -t 1
1 miner threads started, using SHA256 'c' algorithm.
HashMeter(0): 16777215 hashes, 822.86 khash/sec
HashMeter(0): 8388607 hashes, 823.86 khash/sec

Whatever version of libCURL you linked against isn't redirecting to the correct URL.  Use the correct URL and password parameter in the arguments instead and it should work.

Code:

./rpcminer -url=http://mining.bitcoin.cz:8332/ -user=user.1 -password=pass

I compiled with curl 7.21.2 and appended the "/" on the end of the url and got the same result, 0 khash/s

Also, I was able to use the command line to get a response from the server using curl.

Code:

Updated first post with latest release.  The only major change is this release will let you know if there was an issue getting work from the server and will stop hashing stale blocks.

I really appreciate those updates!  I got the new source and built, now I get:

Code:

./rpcminer -url=http://mining.bitcoin.cz:8332/ -user=hidden.1 -pass=hidden
Client will start 2 miner threads
Work will be refreshed every 4000 ms
Could not retrieve work from RPC server.
CURL return value = 22

I'll start trying to figure out what's up with CURL...

Just a couple things I noticed using tcpdump -A and watching the html packets when executing /usr/bin/curl and rpcminer.  /usr/bin/curl sent a GET request and i'm not sure what data to expect as a response, but I got an HTTP/1.1 200 OK when using /usr/bin/curl manually and it responded back with that string I listed above, which looks like what you guys are probably parsing as the data input for the program.  When I run rpcminer, it is using a POST request, and from looking at the source you are using a content-type of "application/json" and I get an HTTP/1.1 401 UNAUTHORIZED as a response.  Are these recent builds working for anyone using linux/mac osx?  It could be my libcurl install is messed up somehow, but I used mac ports.  We could verify it is my setup of libcurl if someone else can compile the current source for linux/mac osx and it successfully gets data.

thanks for all the help and time so far!

It's returning unauthorized because you're not supplying the password correctly.  The parameter is -password not -pass.

I found if I comment out this section in "rpcrequest.cpp",

Code:

        std::ostringstream istr;
        istr << m_readbuff.size();
        std::string headersize("Content-Length: "+istr.str());

        headers=curl_slist_append(headers,"Content-type: application/json");
        headers=curl_slist_append(headers,headersize.c_str());
        headers=curl_slist_append(headers,"Expect:");

        curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);

It computes hashs and I get a
Target = 00000000ffffffffffffffffffffffffffffffffffffffffffffffffffffff

[JollyGreen]

I think I'm finally getting somewhere,

I added
curl_easy_setopt(curl, CURLOPT_VERBOSE, 1);
to your code and compiled.  Upon running I get some very interesting results in the verbose debug of curl.

Code:

./rpcminer -url=http://mining.bitcoin.cz:8332/ -user='hidden.1' -password=hidden

Looks like the user string getting passed to curl is varying for some reason, notice after the last Server auth with user 'thin???' it is followed by a HTTP/1.1 200 OK.  I guess in that case lib curl is masking the user/pass info with '' ?  Could it be that the string used to create the username/pass combo is having it's memory stomped on or some other weird memory thing?

[JollyGreen]

I think this is confirmed....it seems like lib curl should copy your userpass string into its own internal buffer, but I don't think that it is doing that.  You have a local variable defined for userpass and are calling curl_easy_setopt(curl,CURLOPT_USERPWD,userpass.c_str());

that local variable is getting blown away after it leaves the scope.  I defined userpass as a global variable for a test and then the curl debug always has the correct username rather than the varying "garbage".  Also, I get < HTTP/1.1 200 OK everytime and it is performing ~ 1500 khash/sec

I also get
Target = 00000000ffffffffffffffffffffffffffffffffffffffffffffffffffffff
not sure if this is good or not,

basically I'm using your software asis, but I made userpass a global variable, not sure how best to do that or if this is a correct fix yet.  I wanted to get your opinion

Any ideas?

I tried all the suggestions listed so far in this topic and feel like I am missing something.

The one thing I havent done is:

As I said before, if you don't see a line that says "Build program rval=0" the kernel didn't get built successfully and you're not going to be doing any hashing.  You can try this kernel.  If that doesn't work you'll have to edit the kernel and find out what's causing it not to build.

I tried the other kernel, no luck... and i have no idea where I would start with editing the kernel, but if someone could point me in the right direction... or has an idea... I would appreciate it!

I'm not familiar with miner source, but does it support long live http connections, "keep-alive"?
