Issue : Miner cant connect to P2P Nodes

Miner connects to normal pools w/o Problems, but on P2p we have a stratum auth failure.

Solution found by xmk3 (will post in here below me)

Right, so this is the best version of cgminer for modded gridseeds. However, P2Pool mining is broken for this branch of cgminer-gc3355:
https://github.com/jmordica/cgminer-gc3355

To fix it you need this older branch (that doesn't support freqs above 1150):
https://github.com/girnyau/cgminer-gc3355/

Then you'll build the old branch, but first:

1) From the new branch, copy the driver-gridseed.c, and driver-gridseed.h into the old branch.

2) In the old branch, open miner.h and add the following code beneath line 1048:

extern char *opt_gridseed_freq;

3) In the old branch open cgminer.c and add the following code beneath line 178:

char *opt_gridseed_freq = NULL;

AND the following code block at line 1053:

static char *set_gridseed_freq(const char *arg)
{
opt_set_charp(arg, &opt_gridseed_freq);

return NULL;
}

After that, while in the directory for the old branch run:
./configure --enable-scrypt --enable-gridseed
make

And then you should be all set with high frequency support for P2Pool on your modded gridseed! Cheesy

This doesn't work for me with GridBlades: the "old" patched version is running at an extremely low hashrate (and from what I see, it misses fixes for number of chips, which explains it...).

Instead, it looks like the regression in the jmordica branch was introduced in the commit added support for NiceHash.com, I don't have much time to check what is wrong with the new code, but pulling the repository just before that and compiling it works fine for me (good hashrate+connection to p2pools). In case others are interested (but you obviously won't be able to mine at NiceHash.com... maybe it's better than not being able to mine at *any* p2pool Tongue

), here is the recipe I followed:

Code:

git clone https://github.com/jmordica/cgminer-gc3355/
cd cgminer-gc3355
git checkout f20c066127a843cc75b79a3a29f80cf890341ec6
./configure --enable-scrypt --enable-gridseed
make
./cgminer --script ...
