cgminer extranonce.subscribe extension (binaries available for download)

[miguelmorales85]

My S5 work fine with #xnsub but I cant make my Avalon4 and SP20 to use #xnsub.

Could you provide screen shot of myminer.io to see how you write it. Maybe Im doing something wrong.

Thanks

For avalon you have to compile your own cgminer (or use provided if you're using Linux). Devs should add extranonce.subscribe to firmware.

For SP20 - first check which cgminer version do you have - check at SP20 homepage - is it written cgminer4.7.0 or cgminer4.8.0?

what can I do after I check if the SP20 have the cgminer4.7.0 or 4.8.0?

in the pool configuration does the #xnsub parameters goes after or before the stratum+tcp:URL address?

If you have cgminer4.7.0, then first update your miner to the latest firmware. And then you have to use SSH (download putty on windows or use "ssh" command on linux/mac). You can connect as "root" (password "root") user to your miner's IP address and then issue these commands:

cp /etc/bin/cgminer /etc/bin/cgminer.orig
cp /cgminer-extranonce  /usr/local/bin/cgminer
cp /cgminer-extranonce  /etc/bin/cgminer

Then set your pool connection URL like this:

stratum+tcp://stratum.westhash.com:3334#xnsub

or

stratum+tcp://stratum.nicehash.com:3334#xnsub

And restart miner.

Now you'll notice cgminer4.8.0 version on your miner's home page and extranonce should be enabled.

first update firmware for S1

[russy121]

ty for the reply

but can you paste me the link for the firmware you suggest
as i did it with the latest firmware from bitmain

[Subw]

i take it from bitmain's site: antMiner-S1_openwrt20140207.bin
follow the instructions in txt file from cgminer archive and you will be fine. i have eight S1 and they work with extranonce @nicehash

[nicehash]

Here is an updated firmware for AntMiner C1 which includes cgminer 4.9 with extranonce.subscribe, feel free to try it out: https://www.nicehash.com/download/antminer_c1_4.9.0.tar.gz

Please note that this firmware was provided by third-party (smit1237; https://bitcointalk.org/index.php?action=profile;u=363314), and was confirmed to be working (https://bitcointalk.org/index.php?topic=841344.msg10706798#msg10706798)

i have followed the nicehash/westhash guide

[Subw]

i have followed the nicehash/westhash guide

same here, i don't think this is a problem, pool registers full speed of the miner so don't worry

[russy121]

phewww i will just leave it running then ty

What about the S2

[nicehash]

A quick update for Spondoolies users (SP20, SP3x): if you upgraded to a recent stable firmware you'll have an option to set "ExtraFlag" = "2" at the "Settings" page. After setting this flag you only have to reboot the miner (not just restart the mining, but actually reboot it) and it will boot into cgminer4.8.0 with extranonce.subscribe enabled (no need to use SSH, etc.). Then set your pool connection URL and you're all set:

stratum+tcp://stratum.westhash.com:3334#xnsub

or

stratum+tcp://stratum.nicehash.com:3334#xnsub

Hi, can somebody tell me the commands to put in ubuntu command line after I downloaded the git repo for cgminer 4.9.1 how to include the extranonce subscribe extension please? I see all kinds of links to where it is but I don't know how to merge it with the one on my computer.
Thanks

what does exranonce do?

[emdje]

Take a look at this to read up on what extranonce does: https://bitcointalk.org/index.php?topic=1040859.0

what does exranonce do?

It says to the work source that is providing you with work, that they are allowed to change the coinbase transaction however they like whenever they like.
It is a major security risk.
