BE tube or do you mean BE Cube?
I've tried to get the stratum proxy running for solo mining via the Qt wallet and gave up very quickly. Much simpler way is to install Bfgminer and proxy through that using the --http-port option, works a dream. Don't forget to run the Bitcoin-Qt with the -server argument.
Although it has to be said if you are only planning on solo mining with a BE Cube, you're wasting you're time, you will never solve a block.
OliRS, many thanks for your help. Sorry for my mistake it's Erupter CUBE not "Tube".
I have used bfgminer for proxy, I used this command to start my bfgminer:
bfgminer.exe -o 127.0.0.1:3333 -u rpcuser -p mypassword --http-port 8332but I got a strange error:"[2014-03-22 19:50:10] blktmpl error: Unrecognized block version, and not allowed to reduce or force it", I mining the SHA coin, I deleted whole directory and re-install QT program and the error still exist. And when I used bfgminer for proxy I got low efficieny, about 86%. That why I decide trying use mining_proxy.
I made a few attempt again, I noticed the mining_proxy not listen at 8332 port, even I add "-oh localhost -gp 8332", and then I found mining_proxy connect the stratum server failed. So, I don't know what is wallet QT's protocol? It seems not getwork and not stratum.
About solo mining's point, I believe you are right, most time solo mining is meaningless, I only trying solo mining for some new crypto coin with low difficulty.
