Add crontab to execute it every 2 mins

  1. I had to make some alterations to this to get it to work. Putting sudo in front of each instance of ifconfig, ifup and ifdown seemed to solve it. Otherwise I would get an error that each of these commands was “not found” in the output log (I directed crontab to write them to a log file instead of set up email notifications). This was even after changing permissions. After making these changes, things worked great!
