guys, when I do putty, what is the username and password?
Default user is m1 and password is miner1

you are the best! thanks! oh and how do we change the bash file or the miner settings from putty? and how to stop the miner and start? thanks!
In v0019 you dont need to kill 3main. just killing miner will make wdog re-init 3main and run it with your new edited 1bash
but if you want to kill best way is :
pkill -e screen # to kill miner, wdog and temp
pkill -f 3main # to kill 3main
bash /home/m1/3main # to load 3main again
one line cmd :
pkill -e screen && pkill -f 3main && bash /home/m1/3main &
Click enter when 3main loaded, and miner started, dont do ctrl+c
