Twenty Tricky SysAdmin Tasks… And How to Approach Them

  • Twenty Tricky SysAdmin Tasks… And How to Approach Them-

    Maintaining the same DNS namespace across two or more zones tends to drive most admins a little bit nuts. There’s a reason why it has been dubbed a “split-brain” DNS. The key to this task is to perform both the internal and the external updates at the same time. If you have two monitors, run one admin console (or BIND file update) on each monitor, keeping the internal on the left screen and the external on the right one. Get into the habit of also keeping an NSLOOKUP cmd running on the left, and a DIG cmd running on the right, to force that separation while still ensuring that you do both zones at the same time.

A SysAdmin has an almost endless list of tasks they must complete on a regular basis. Some are so routine that they can be done while multitasking, others require careful attention to detail and a laser-like focus to ensure that things are done well and completely. While many admins may look at most of the tasks on this list as run of the mill, they frequently present a challenge to others. In this slideshow, Christina Goggi, writing for GFI Software, provides some tips on how to approach them.
