Solo Mining with Hardware

[vmfx]

Hi all,

I have been lurking for a while here as I have grown my rig from GPU to ASIC and now to a couple of Antminer S1s - next step will be 2TB's  and beyond and thanks to everyone here for all the help in getting there to date.

I am re-purposing all my U1's for solo mining, since their return against my new rigs is now negligible and i find watching the mining hardware keeps me company whill I am geeking out here writing code.

I am trying to find out what the best setup for BFGminer (or CGminer for that matter) for solo mining using a hardware rig (for me thats currently 10 Antminer U1's giving me around 20GH of solo mining speed).

Assuming I have the latest version of bitcoin-qt running, and the latest version of BFGminer, from what I understand :

1. I need to have long-polling enabled to make sure I am not working on dead shares ? and to do this I need a failover pool ?

2. I need to optimize my settings for scan time, queue, expiry and turn no submit stale on

Is there anything else I REALLY need to be doing ? I can only assume that the large pool operators have tweaked the hell out of their setups for solo mining - care to share ?

Here is my BFGminer setup :

./bfgminer \
 -o localhost:8332 -u bitcoinduser -p bitcoindpass \
 -o http://stratum.btcguild.com:3333 -u user_worker -p pass \
 --failover-only \
 --api-listen \
 --scan-time 1 --queue 4 --no-submit-stale \
 -S Antminer:all --set-device antminer:clock=x0881 \
 --coinbase-addr mywalletaddress --coinbase-sig "This is VMFX's block"

Any help much appreciated!

So based on further digging I have updated the scan-time options to be

--scan-time 2 --queue 2 --expiry 2 --no-submit-stale

if there is anything else I can do feedback is much appreciated!

I would also like to know if I run my bicoind on a separate server, can I solo mine on multiple boxes by pointing them all to the same bitcoind server especiall if i am using

--coinbase-addr 12SVJ3o3jSSnR4PDKWAPLDHnoY7qiFUu1C --coinbase-sig "This is VMFX's block"

to direct my payout address ?

...or would I be better installing a private mining pool like eloipool for this ?

So, I have noticed that when I use the failover pool my miner doesnt detect blocks on the network ?

 [2014-03-17 19:54:19] Pool 1 is hiding block contents from us
 [2014-03-17 19:55:19] Block change for http://127.0.0.1:8332 detection via  http://stratum.btcguild.com:3333 stratum

then it just hangs there and doesnt detect any blocks on the network - though if i turn verbose mode on I can see that my ASIC's are hashing away ?

If I leave out the 2nd pool and add

--no-longpoll

Then it works fine, and i can see blocks being found on the network no problem ?

There is always Ozcoin's solo pool as an option.

yes seen his pool - thanks! - though it feels like cheating should be able to get it working on my box!

but with the difficulty so high I guess there is just no way to really know for sure or get much help since it seems no one is solo mining these days!
