can someone answer a question about all this firmware exploit talk …

Question one, if you revert back to "FLASH to the last released firmware" would it clear the exploited box ? I get that the Firmware has a hole that MAY be exploited, but could this be stopped by closing a network hole in your own network ? I'm not looking at pointing fingers or debating who's responsibility this is … I manage S2 and S4 box's and I have yet to see any of them exploited . so the next question is, how are these box's being set up so that they can get access to the outside world to be exploited ?

It's a stratum exploit in older versions of cgminer & others, not in the firmware itself. The only way to fix it is by upgrading cgminer. Also, just because you haven't noticed it - it doesn't mean it hasn't/isn't happening Wink

Guess I should set up wire shark to check it out ...

My new PSU just arrived, no duty, tax, etc.

I'll install it when I get home tonight.

Got my first replacement last Friday, put it in and it works great so far… Still no refund on the 10 days mining compensation , I was down for far more then 10 days but at least I'm up and running now … The other two PSU's for the two units that were not impacted should arrive today … On the down side I have to unrack those units and take them apart to make the replacement..

Bitmain, im glad you sent out new PSU's but you forgot to put in a few additional zip ties … just saying lol …

Today received a new PSU for S4. To custom.
with the invoice 140 USD But you can not marked the cost of shipping.

Thanks a lot - BITMAINTECH - for stupidity.
For sending 2,5kg PSU in 1 kg UPS shipment. Do not have the option of weighing ? UPS does.

And now I have to pay custom duty for the shipment weight per volume. 3,5kg. Declared value total 240EUR.
Only 48 EUR + 22.80 EUR for the custom declaration to UPS.

A total of 70 euros for the fact that you have sent me with the S4 a piece of shit, not PSU

Thanks a lot, for new PSU.

This is Tim Shao from Bitmaintech.

At last! A real Bitmaintech employee who can offer some real support, not a moment too soon either.

I hope he cleans up all the dogie poo left on this thread...... Cheesy

hi, dogie is the right person to help u with the operation guide and technical support.
please understand that sometimes customers may come across problems with your miners due to various combinations. And it did happen before we received the so-called faulty items or even the whole unit and found it was actually running well.
And if you found some hardware problems, like the faulty hashing PCBs, controller boards,etc, you can send an email with your RMA request to this email address: [email protected] or contact Bitcoinwarranty directly. We will arrange a return accordingly.
Anyway, we will try to improve our aftersales service.

I would rather deal directly with Bitmain than go through a paid off messenger boy with a bad attitude who's committing tax fraud, thank you.

Can you tell us why you still haven't released the S2 firmware you promised 9 weeks ago to fix the security issues & update cgminer?

Why have you not fixed the latest S3 firmware that actually breaks the S3 & lessens its performance - surely you should take it off your support page?

Will S4 users also have to wait over 9 weeks for a firmware fix & so allow them to use a pool of their choice?

I notice Spondoolies are now issuing compensation payments to their customers for lost mining time & underperforming units - will Bitmain be doing the same?

Thanks.

Hi, yesterday I received an email about sending 3 new PSUs and information that other 7 will be shipped ASAP. I was really happy because I have had 3 miners without PSUs, but not for a long time. Nowadays I have 10 pcs S4 B1 and 10 pcs S4 B2 and a lot of S3+ miners.

Today morning when I arrived to work I smelled burnt stink. Employees were scared, called me and ran around. WTF I said for myself. I hoped that the reason for all arround was not caused by miners but I was not right. I looked at the miners and two of them were down. Immediately I switched off all breakers dedicated for miners. And yes, one miner had PSU burned down. It was very easy to find which miner was bad Sad

It was the fourth failed PSU. I checked all breakers and only one was switched off automatically.

When the smell disappeared from the building (after 2 hours) I started with switching on the breakers one by one. After that I switched on PSUs on S4s. But another one from B1 and also one from B2 could not start. Also fans were stopped. I tried to reconnect the power but nothing helped. I have not understood what happened. All miners were running more than one week continuously.
The PSUs do have really some problems. I hoped that PSUs in B2 were good, but....or today is only bad day for mining

Today status is 5 failed PSUs from 10 pcs from B1 and one failed PSU from 10 pcs from B2.

Truly sorry about that, Sir. This is Tim Shao from Bitmaintech. You may have received an email from [email protected] asking you to specify the PSU type. And i wonder if you can provide some photos to show us the burned PSU, i'm not asking you to risk running the miner again. But it does help if we can glean some actual info from the affected customer and submit them to the PSU supplier, and this will also help us improve the product quality to prevent this from happening again. Thank you for your understanding.
I have the following questions:

1.
"I looked at the miners and two of them were down. Immediately I switched off all breakers dedicated for miners. And yes, one miner had PSU burned down. It was very easy to find which miner was bad"
Two were down, and one miner had PSU burned down? Which one was burned down? And what about the other one? Stop running? cannot power it up?

2.
And you mentioned in the following posts that your B2 has barcode on it and you are sure it's not from the defective batch, can you provide me your order id for this miner, or would you please send me a photo of it? Thanks.

Hi all, yes I have received the email. I am sure that the PSU is from batch 2 (have sticker and SN).
Answers for Tim.Shao19:
1. My miners are connected in pairs to single breaker(2xS4 to 1xC20 breaker). When one PSU burnt down and breaker for this miner went down also another miner switched off. Is it clear?
2. Order is 00120141014004349482tuQeQyd106EE from 2014-10-14 00:43:50.0. PSU SN:188A410120045 PSU don't have visible changes outside and also inside.

Hi there, we may have sent replacement PSUs to you, have u received any tracking no for the replacements? or you can provide me your email address or order id, then i will double check and keep you informed. And can you please provide any proof on your burned PSU if possible? (i know it may be difficult to tell the burned PSU from the appearance.) we need to glean some real info from customers and feedback with the PSU supplier rather than just claim that we got bad PSUs. Thanks.

Yes, you can do so, but you have to log in to S4 via SSH.

Putty software can be downloaded from their website @ http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Modifying the config file value that is not modifiable via the web control panel, may voids the warranty. Use CAUTION when you modify this setting.

Any file you attempt to make changes, please make a back up file first!!

cp originalfilename originalfilename.copy

then use command such as "vi" to edit the file.

If something really goes wrong, you can always try to factory reset the S4 by using a paperclip to the bottom hole (left side bottom) next to the LCB screen. Press and hold the button for at least 5 seconds and let it go. Then wait for 2 minutes, power it off and power it back on!

If that doesn't work, you can always reimage the default image file from http://www.bitmaintech.com Support Page.

Would something like this apply to the S4 to mine multiple pools simultaneously? https://bitcointalksearch.org/topic/bitmain-antminer-step-by-step-how-to-setup-balance-mining-tutorial-395721

Or how would we achieve that for the S4?

How do we make changes like this via SSH to stay on reboots?

Thank you so much for the time you've invested to make the S4 more funtional, ckolivas. I'm going to send you a donation tomorrow morning.

I'd like to try ck's new version tomorrow, but I have no idea how to go about updating cgminer. Can anyone shed some light, or point me towards a guide?

Assuming your S4's IP address was say 192.168.1.99:

Code:

ssh -l root 192.168.1.99 (or equivalent with putty)
wget http://ck.kolivas.org/apps/cgminer/antminer/s4/4.6.1-141018/cgminer
mv /usr/bin/cgminer /usr/bin/cgminer.bak
chmod +x cgminer
mv cgminer /usr/bin/cgminer
/etc/init.d/cgminer.sh restart

I think that might not keep across a power cycle though.

Updating cgminer gets defaulted back to it's original cgminer on reboots.

You haven't answered HOW to do this. What to modify. Which settings to change.

One way is to change the setting on the fly via the screen session, mainly to test it.

1. SSH to S4, Login root/admin. (I use putty.)
2. Type "screen -r" to enter the running screen session, assuming it is running with default image and settings.
- While in the screen session, many messages will go by. You have to read through them.
3. Type "P" to enter Pool Management.
4. Type "C" for Change Management Strategy.
5. Select one of the following: "0"-Failover(default), "1"-Round Robin, "2"-Rotate, "3"-Load Balance, "4"-Balance.
- Load balance requires quotas to be setup first. Balance uses equal share across configured pools. Read the cgminer readme files for more detail.
6. Press Enter key to exit Pool Management menu. Should now be back at main cgminer menu.
7. Exit screen session by issuing "Ctrl-A", "Ctrl-D". (Hold down Ctrl key, press "a/A", then "d/D".
8. Now back at shell prompt.

Hope this helps.
-Scott

This feature is not officially supported. https://bitcointalksearch.org/topic/bitmain-antminer-step-by-step-how-to-setup-balance-mining-tutorial-395721 option can be used if you manually modify the config file, however, the risk of messing up the S4 is too high. (Most of the config file mistakes can be reset via factory reset)

https://bitcointalksearch.org/topic/bitmain-antminer-step-by-step-how-to-setup-balance-mining-tutorial-395721 should give you some insight how to do this step by step!!!

Just mine in solo with this equipment... Even if it will find one block in one year - it's better than any possible pool mining...

What about if no block is found in that time?
So its better to be in a pool than solo.

just got my tracking number too.. but here's the question, do they expect us to pay for the import duty? and same with sending their psu back to them as suggested in the last email? cause thats gonna hurt my wallet if i have to pay for that again..

Duty? Not in the US at least. Is part of the shipping cost.
As for returns/replacements. No duty as long as parts are marked as warranty replacements. Even if Bitmain wants to old one back as long as marked as a Return no duty applies (plus if any did would be their problem, not yours)

the last time i had an issue with the s2 they took the old hashboard back, they were meant to pay the duty, they didnt pay it, and ups were up my ass for the money, so in the end i had to pay for that too
