JSON parse error: ?Version and Error from bufferevent error during bitcoin solo mining.

[jeong760]

Hi

I've received a following error message during bitcoin solo mining using Bfgnminer 5.4.1

• SSM: JSON parse error: ?Version
• Error from bufferevent

Regards,

[luke-jr]

Something else did this.

[jeong760]

I was start with following command in order to do bitcoin solo mining with 2 of Antminer S3+ and Spondoolies SP20 miner on windows.

after I ran with following command miner able to connect on but continuously received an error mesaged above. so I don't know how I solved this.

• bfgminer --stratum-port=3333

And miner I was set following
Stratum+tcp://192.168.1.5:333
Username
Password

[jeong760]

Dears,

I was updated what I did with BFGminer.

Regards,
John Ahn

Note that solo mining with --stratum-port is broken in all released versions of BFGMiner, and only latest git is likely to work correctly. In any case, the error is a connection that doesn't do stratum correctly.

[jeong760]

Ok, thank you. so what is correct methond in order to do solo mining with Bfgminer?
And only last git works correctly with --stratum-port option then how do I build for windows version?

[luke-jr]

Generally you would run BFGMiner connected directly to the hardware (ie, on the controller).

You can get the latest git built from http://luke.dashjr.org/tmp/code/webisect/webisect.php?dobuild=bfgminer

[jeong760]

Dears,

Thank you.
and how I setup a solo mining configuration on bfgminer.conf file such as pool and connection port?

John Ahn

Dears,

Following linked Bfgminer is support a --stratum-port option?
When I use that option then I've received an error message that " SSM: No usable 2D work upstream!".

Could you give me a hint for http-port option of solo mining?

John Ahn

[luke-jr]

Can you post a debug log?

bfgminer --debuglog --log-file debug.log --stratum-port 3333

[jeong760]

Ok, please give me a time.

[jeong760]

Dears,

Here I upload a log file but just I changed its extension name as txt because of Git does not support a log.

debug_20160324.txt

[jeong760]

This is bfgminer version 5.4.1 that I download from bfgminer.org. it works with --Stratum-port=3333 but still have an error message and miner goes to Sick mode.

•SSM: JSON parse error: ?Version
•Error from bufferevent

debug.txt

[jeong760]

Dears,

Any update result from the log files?

[jeong760]

Dears,

I've already uploaded a log files for bfgminer with --stratum-port option.
Could you guide me any solution?

I've fund that JSON parse error clue on Git but not sure this is related with bfgminer's behavior.

I see why it won't work for you. I need to wrap up a new version. Give me a few days.

[luke-jr]

(Note this won't fix your original/main issue, though - the ?Version stuff is a problem with your miner)

[jeong760]

Dears,

Thank you. I am surly wating for a new version.
So what is the main issue of current one?

John Ahn

[jeong760]

If the ?Version issuse is my miner problem then what kind of thing do you fixed on next version?

[luke-jr]

The main issue is that working GBT->stratum support requires a newer version of libblkmaker, and is only compiled when the newer version is detected; but it is never detected, because the version number has not been bumped in libblkmaker yet (and the version used in the git submodule is too old anyway). So to finish fixing this, I need to complete the release of the new libblkmaker.

[jeong760]

So, do you possible to solve it on next version?

[luke-jr]

You can try http://luke.dashjr.org/tmp/code/webisect/webisect.php?dobuild=bfgminer again.

[jeong760]

I was tried to run a bfgminer again, which downlaod form above link. but when after start it I've received an error. and I think above linked bfgminer already try to use before.

[jeong760]

What does "Error from bufferevent" meaning? and why does it occurred during solo mining?

[luke-jr]

[2016-03-26 06:32:09] SSM: JSON parse error: {"params": ["jeong760", "56f5ae55-2", "1602", "**V?**e52", "766c90b7"], "id": 5404, "method": "mining.submit"}

This is garbage (see the part in bold). Old versions of cgminer (likely on your miner firmware) are known to have this problem. You'll need to either put BFGMiner on the firmware and use it directly, or at least upgrade the cgminer.

What does "Error from bufferevent" meaning? and why does it occurred during solo mining?

It doesn't, unless your miner is broken.

[jeong760]

I saw that you updated a libblkmake to 0.5.3 version. Does it solved a my issue with bfgminer? if so, I will compile it on windows version and test it again.

[jeong760]

Antminer S series uses a Openwrt but I am not professional to import a BFGminer onto that firmware.
Current cgminer version is 4.6.1-1.

[jeong760]

Sopndoolies SP20 uses a cgminer 4.7.0 version but they've already discontinued this product so no more care about product.

[jeong760]

I was update a cgminer 4.9.0 version on my ANTminers and now there is no Pasrse error. But dueing mining process miner speed is continuously downgrade. It was start as 800GB but 5 minutes later it will decrete as 100GHash in total.

Does it related with bfgminer or my miner's settting issue?

[luke-jr]

Maybe try running bfgminer with --set pxy:diff=128

Happy Easter!

[jeong760]

Happy Easter too

[jeong760]

If I disable a Long-pool using --no-long-pool option of bfgmeiner then what will affect? And what is the long-pool?

[luke-jr]

Longpolling is an optimisation. It has no practical use for disabling, just testing.

[jeong760]

How I express thank you?

[luke-jr]

Please feel free to make a donation to 12hzAYYxm8fTEGRPCRYfSLuk3H5Uwzyx7h if you like.

[jeong760]

Do you accept PayPal? I am start a BTC mining so..

[jeong760]

Following logs are meaning that my miner work for solo mining againest to my personal wallet software. and I was placed my BTC addres as BTC address for just in case.
Am I correct?

[luke-jr]

If you would like to donate via PayPal, please use <retracted> for the email address.

The log looks okay, but note that the stratum username ("BTC address" in the log) is ignored entirely.

[jeong760]

Luke-jr, your PayPal account is not vaild. please check and leave here correct one.

[jeong760]

if stratum is inore my BTC address then how I get a BTC when found? it uses a coin base address, which generate by bfgminer when it start. am I correct?

[luke-jr]

It generates directly to your wallet, using an address your wallet gives it. Or you can use --generate-to ADDRESS to override this.

For PayPal, that is the correct account I login with. You can also try http://paypal.me/lukedashjr

[jeong760]

PayPal.me is not availble in my country. let me know your vaild account.

[luke-jr]

Oh well, I guess PayPal is broken then. luke+paypal@dashjr.org is correct.

[jeong760]

Sent.. please check with PayPal account. and I want to lean about Eloipool setup for my personal mining of bitcoin..

Anyway thank you and appreciate you.

John Ahn

[luke-jr]

Thanks. Note that Eloipool does not support Windows, so you will need a Linux system to set it up.

[jeong760]

Yes, I know and I am famlier deal with Linux OS. I found that following link but is this need to installation a MySQL as its data store location?

Link: luke-jr/eloipool#3

What I did

• Installation a Ubuntu 14.04LTS
• Installation a bitcoind and bitcoin-qt and finished a block sync
• installation a MySQL and its GUI management program

I wat to know exact installation guide for Eloipool but only I found that above link.

Do you have any good guide for it?

[luke-jr]

No, I don't have any guide. If it's just for you, you can just disable share logging with ShareLogging=()
Then no MySQL is required at all.

[jeong760]

Thank you.

[jeong760]

By the way how I download a midstate

[luke-jr]

You don't need it.

[jeong760]

But midstate is mandatory option for The Eloipool setup?

[luke-jr]

No, it works fine without it.

[jeong760]

Could you give me download link for midstate? Http://gitorious.org/midstate/midstate is dead.

[luke-jr]

Again, you literally do not need it. Every miner since 2012 does the midstate on its own.

[jeong760]

Ok, so I will go forward to make my own pool.

Thank you
