my 3 b1 S7 miners goes to silence yesterday, they can reachable but dont hashing, cgminer cant start hashing.
i tried nearly everything 1 solution is flash new firmware and go. but i am using 6hashboards
latest version is not handle 6 hashboards.
I suspect for date settings with ntpd . like a timebomb. change date settings to 2015 not works.
any ideas ?
i am not linux guy i cant figured out.
I had the same problem today and some days in the past also.
When you start or restart cgminer the cgminer.sh script (/etc/init.d/cgminer.sh) checks that the connectivity to 114.114.114.114 is up.
I guess it is a one of bitmain ip.
Today this IP (
114.114.114.114) is
down, so all of Bitmain gear (S3, S4, S5, and S7) will refuse to restart cgminer if you restart the miner or change your configuration.
If 114.114.114.114 is not up, the cgminer.sh script exits and does not start cgminer.
To fix the problem there are 3 possibilities:
1) Wait for 114.114.114.114 to get back up => Seems unacceptable to me.
2) Upgrade the firmware to a newer version
3) Fix the script and restart cgminer.sh
To do that :
3.1)Connect to your miner by ssh
Replace 192.168.0.170 with the IP of your miner
3.2)Edit /etc/init.d/cgminer.sh and comment out 3 lines from line 35 to 37:
vi /etc/init.d/cgminer.sh
#if [ $network_ok -eq 0 ];then
# return
#fi
If you don't know how to use vi :

/etc/init.d/cgminer.sh restart
Warning :You will have to redo the same modification if you reboot !
To avoid that, do after fixing cgminer.sh:
cp /etc/init.d/cgminer.sh /config/cgminer_fix.sh
And then if you reboot you only need to do :
cp /config/cgminer_fix.sh /etc/init.d/cgminer.sh
/etc/init.d/cgminer.sh restart
