cgminer extranonce.subscribe extension (binaries available for download)

hi nicehash, i am hashing 1Th on your pool but you must to know;
S4 and C1 uses ram file system (initramfs) from SD card, So our any changes will not stay forever, it will work until reboot.
if you want a solid solution, you can teach initramfs modification to us simply.
Best Regards.

It is not problem to log in S4 via ssh and upload binary. Problem is that binary is not compiled for S4.

Ok for us noobs that have no idea how to use linux or putty, Ive got a really dumb question. How come you (the devs) dont make it so that we can log in to our antminers and use the "upgrade" option, and reflash the modified binary file? This to me would be by far the easiest solution. Does this not upgrade cgminer? Is there something I dont know?

We are waiting for Bitmaintech to incorporate this patch into the firmware, but is not released yet, and currently we don't have release date for the new Antminers firmware. Until then, the only way is to manually upload cgminer binary.

Im sorry Im not a software dev, but is there anyway to take their existing firmware and modify it? In other words put the image in their format that their upgrade tool will recognize. They also have a restore command, is there anyway we could use that?

[raskul]

i have no clue how to apply this
i have;

2 x S3+
3 x SP10
1 x SP20
1 x SP35

any help would be greatly appreciated.

Just got it working on 2 S3+ units. I had to use PuTTY and WinSCP together because I am a noob... who cares it worked and now going to try it on an S1

[xZork]

Well crap... it says I have Extranonce subscription but my hashrate drops to 40-50 ghs....  I messed something up.

[xZork]

When I mine on a different pool my hashrate is fine, but when I use westhash it drops. Is something wrong with the pool?

Hello.

I am testing it in antMiner S3 Bath 8.
I Update the last firmware antMiner_S320141126.bin, update the cgminer 4.7.0 and add #xnsub in the pool.
But in 20min, the S3 stop mining and reboot cgminer all the time  . I load default config, but the problem continue. Did you past this has anyone?

I was reinstall the firmware antMiner_S320141024.bin and now it is worked again. I was installed the cgminer 4.7.0. and add #xnsub in the pool and work OK.

I search a new versión of cgminer 4.7.1 or 4.8, but I don't found any new version for S3. If is posible anyone compile it, please?.

If is possible do it in antMiner C1?

Best regards.
Antuam

We have prepared pre-compiled binaries for Spondoolies SP20 with cgminer 4.8 and extranonoce.subscribe patch (instructions included in README file):
Spondoolies-SP20-cgminer-4.8.0.zip (MD5 checksum: 727bbea1dbee633a7f36825a06596c3a)

For S3+ users, you will have to change permissions on the new cgminer file. Easiest way:

chmod 777 cgminer

in the /usr/bin directory. Then it works like a charm.

Also make sure when connecting with winscp that you pull down the protocol option to "SCP" the default is SFTP. You won't connect.

[tmpwhore]

Ok big problem. After a while the hashrate goes down to like 40Gh/s instead of the usual 450Gh/s. I guess it's still fucked like the extronance proxy. I would avoid this unless there is a fix or I can do some more testing.

I repeat for the S3+ Antminer DO NOT APPLY THIS FIX it will fuck you up for now. Hopefully you've backed up the old cgminer. I've put one miner on this fix to see if I can get it to work. I'm going to see how long, if ever, it will take to recover. So don't apply this "fix" until I've tested it after at least 24 hours. It could be that when changing coins it's gradually reducing the hash rate then gradually ramping it up. Whether this is worth it or not I don't know but I'll be watching.

If you want to reconnect without using extronance just kill the #xnsub suffix on the address. After it dies I'll try and connect without the extronance and see if it's actually the new cgminer causing the problem.

Well crap... it says I have Extranonce subscription but my hashrate drops to 40-50 ghs....  I messed something up.

Yep this is a common problem. I'm doing tests now but so far no go. Read my posts. Trying to see if it's the newest flash or the cgminer as even if I turn extronance off it still does the hashrate nosedive of death with no recovery after 20+ mins on the new cgminer from nicehash.

[tmpwhore]

More tests to go but it looks like the culprit is the latest flash of the S3+ miner. DO NOT USE THE LATEST FLASH FROM BITMAIN. It causes the hashrate nosedive of death(at least on nicehash). Testing with the version below the top:


antMiner_S320141024.bin

and the new CGminer with extronance ON...will advise, so far so good.

[tmpwhore]

Cinfirmed bad or incompatible build. Nicehash I would post something about this on the extronance bug quash cgminer page...

Also just to let you know nicehash your S3+ extronance bug quash works beautifully on the S3+ as long as it's build

antMiner_S320141024.bin

Which is one before the latest. If people have the latest build for the Antminer you get the "hashrate nosedive of death"(confirmed on multiple miners) whether they use the new cgminer build or not. I'm going to put an email today for bitmain with some screenies and an explanation. I would advise people on your site of the new build problem because if the S3+ people flash with the latest bitmain build it basically breaks their Miner to use on your pool.


antMiner_S320141024.bin  <--------Good build

antMiner_S320141126.bin  <--------Bad build(latest)


I'll do my part and email Bitmain with screenshots and an explanation of the problem.

someone has a working cgminer with extranonce subscription for the antminer S4 ?
The one on the nicehash site doesn't seem to work....

However, I am getting over 1900 GH/s accepted using default code.  I set the following in /etc/init.d/cgminer.sh based on the site recommendation.  Edit the line with PARAM= and add "--queue 0 --scan-time 1 --expiry 1".  This is not persistent past a reboot, so have to edit again if reboot occurs.

[eljotik]

hello,

I have completely newbee question.

When I try upload cgminer via putty i receive message: No such file or directory

In guide I found

Code:

scp [path where you download and extracted patched cgminer]/cgminer root@[IP of your miner]:/usr/bin/cgminer

I put

Code:

scp [C:/Users/my_comp_name/Downloads/AntMinerS3-cgminer/cgminer]/cgminer root@[Ip_to_antminer3]:/usr/bin/cgminer

In advence ty for any help

my s4 s working latest firmware 16102014, i copied nice hash cgminer and added #xnsub string but S4 dont start hashing. allways 0Gh.
is this --queue 8192 problem ?
