ANTMINER S3+ Discussion and Support Thread

Now, I'm curious, why do you want to reboot every day?  And, here's another way, put in cron or loop script to run every few minutes or hour

Code:

upsecs=`cat /proc/uptime |cut -d'.' -f1`
if [ $upsecs -gt 86400 ]
    then
        reboot
fi

Since you are good at this sort of thing, how would you write a script that would restart cgminer if the hash rate (which you'd get from the cgminer API) fell below a certain threshhold in an hour?

I know this question has been asked before a long time ago, but I can't find it anymore...
Is there a way to automatically let an AntMiner S3 reboot every eg 24 hours?
Thank you!

This will greatly reduce the life of any electronic item. A large temperature jump (more than 5c per hour) will half the life expectancy of a chip each time. Whilst they may last decades... well you get the idea. However, since these units are only designed to last 6 to 12 months, go for it!

I'm sure this could be cleaner but here's a first go

Code:

sleep 600 # ten minute ramp up time for cgminer? 
mingh=500
lastgh=`cgminer-api lcd|grep -o '\[GHS5s\] => .*$'|cut -d' ' -f3|cut -d'.' -f1`
m=0
while [ $m -lt 3000 ] 
    do             
        m=$(( $m + 5 ))
        thisgh=`cgminer-api lcd|grep -o '\[GHS5s\] => .*$'|cut -d' ' -f3|cut -d'.' -f1`
            if [ $thisgh -lt $lastgh ]                                                 
                then                  
                    lastgh=$thisgh
            fi                    
       echo "lastgh $lastgh"
       echo "at $m seconds" 
       sleep 5             
    done      
        
if [ $lastgh -lt $mingh ]
    then                 
        cgminer-api restart

You ARE good at this sort of thing, aren't you? And yes, thanks for that.
Well then onto the next logical questions .... well, I think they are logical ..
1. would this be a drain on system resources to an extent that it may impact on the actual hashperformance?
2. if I saved the script as /sbin/hashRestart and chmod +x it, would it be enough to run it at startup and if not, what do I need to do?

thanks again.

Save the script as you say, then create an entry for it in cron to run every hour

Code:

echo '0  *  *  *  *    /sbin/hashRestart' >> /etc/crontabs/root

[chinesebob]

And, I have no idea how that will affect your performance, I doubt this script would affect anything, but my guess is it that restarting cgminer would affect performance

Top man! You are good at this, ey? thats done for me and documented for anyone that would like to do the same (the mingh is 500GH/s, so that is good for me as I have mine OC'ed a bit and they run a tad above that, though they tend to fall away).

I'll monitor my poolside performace and report back if there are any adverse effects, else no news is good news!
Thanks again (I keep saying that!)

BITMAIN:

Did your site recently change its security certificate? To one issued by a company in Scottsdale, Arizona?

Having problems logging in after no problems up until just now. Did the password reset request, got the email, clicked on the link, verified and reset the password to a new one, then got the log in page and tried to log in. Got message back saying password was incorrect, but it was the one I had just entered as the new password on your reset script/page.

I tried the log on and the reset process in Firefox and IE, with the same results in both.

I'm wondering if anyone else is having this problem, if your site has been hacked or there's a 'man in the middle' attack going on.

1Neptune,

Walk softly my friend.  I am able to login with no issue.

Thanks. It appears to be from them changing / integrating their web site with the antpool and their system didn't like the special characters I used in the new password.

My app can do that.

What are you guys accomplishing by rebooting the miner every hour or when it hits a threshold?

[cdjbolton]

Hi everyone.


Just received another 4 machines from bitmain today, 3 machines are running really well, better than any have before.

But one machines seems to have a dead board, When it was first switched on there was one string with just x all across, after a while it disappeared all together, So it appears only one board is effected, I have checked the internal cables, and also swapped the control board out to make sure it wasn't that.

How is bitmain with its RMAs - As touch wood this is the first machine out of 30 to have an issue.

Also any advice on maybe getting this one working would be much appreciated.

I had the same issue. My old password had a special character in it as well, and after going through the password retrieval process, I saw the interface had changed a bit, and there were no unrecognized logins to my account. Given I don't use Bitmain's pool or hosting services, there's only so much a thief could steal from my account (my coupons that expire in 6 days and Bitmain has said they'd hand out to anyone who wants them?).

It was disconcerting though. And I wish every website supported the same standard password characteristics. None of these "maximum of 12 characters" or "0-9 a-Z only" sites!

Agreed. Good to know I wasn't the only one with the issue.

Go to your scheduled tasks and put this in

0  23  *   *   *     /sbin/reboot

This means my machines reboot every 24hrs at 11pm at night just before i go to bed.

One of mine is acting up (an S3) and I've set it to reboot every 2 hours:

* 0,2,4,6,8,10,12,14,16,18,20,22  *   *   *     /sbin/shutdown -reboot

Hi 1Neptune, praeluceo,

We ever filtered the special characters of password setting to avoid a hacker attack through the password input box. So you encountered above situation. 
But we upgraded software this morning, and currently system accepts the special characters.

Suggest that you reset your passwords again.
