I am having subscription to lab . It’s console is getting time out very fast in just a matter of 30 seconds if it is idle.So if we thinking on a piece of code while writing session get’s times out and we need to start over .
If you are using web console and facing the problem it is recommended to use ssh clients like cygwin or putty to connect big data labs.
Use host name gw01.itversity.com
port number 22
username and password from labs.itversity.com
use CTRL+d to end sessions
