SysAdmin

IMHO, Below is most important things to do, when you’re in sysadmin positions.

  • Respect your user.
  • Don’t fix things that ain’t broke.
  • Never do something you can’t undo.
  • Always check the backups, never assume they are working.
  • Research first, If you really have no idea why you’re changing something, or what it means.
  • Gather all system information configuration automatically every month or before and after make changes on your system.
  • Take some time to build up knowledge about what’s “normal” on your system.
  • If you do it more than once, simple, just write a #!script.
  • Write down all you did on your system.
  • Never stop learning.

May the force be with you

What Does a System Administrator Do?

What is a system administrator? Well, look at the title. Administrator of systems. A system administrator takes care of systems.

Now, most people read “system” to mean an individual computer, and think that all a sysadmin does is clean viruses off your computer and replace your monitor. That’s not wrong — but it is only one page of the whole story.

A real computing system is larger. Very few computers work just on their own anymore; when you use the web, play a game online, share files with a friend, or send email, you’re using a complex and intricate collection of computers, networks and software that come together to do the job you’re asking.

A sysadmin manages these systems — they figure out how to bring storage from one server, processing from another, backups from a third and networking from a fourth computer all together, working seamlessly. For you.

It’s not an easy task. Your sysadmins need to understand in depth computing protocols. They often have to know something about programming, something about hardware, a lot about software — and even more about the people using their system.

A sysadmin is a professional, with complex skills, ethical challenges, and a daunting job. Many, if not most, people find computers difficult to use, and sometimes they’re unreliable. Being a sysadmin doesn’t absolve someone of dealing with unreliable computers. Oh, one can dream of such a day, but the opposite is true; no one sees more dead computers in a day than a sysadmin. No one sees them doing truly baffling things, and no one has more stories of computers failing, acting possessed, or even catching on fire.

The challenge of a sysadmin is making a computing system — a whole network of resources and servers and software — work together, work right, work even when parts of it fail — and work for you.

That’s the most important job of the sysadmin: to work for you. To take the staggering array of technologies, acronyms, protocols, networks, vendors, budgets, limited time, competing products, and threats to the computing network, assemble them all together in a working system. Their job is not only to be the geek in the corner who types all day. What they’re doing is bringing these diverse pieces of technology into order, and fitting them together to fill your needs at work and home; to translate the world of computing into human terms.

This is a daunting task and we’re still at the cutting edge; we’re not perfect, and the field is still figuring itself out. Being a sysadmin takes a certain boldness, to be one of the first people to take on the challenge of turning difficult computers into easy to use systems. But hundreds of thousands of people are working in that field now, from the entry level help desk tech to the corporate CIOs and everyone in between.

So when you think of a sysadmin, think of the people who run the servers that help you clean it off, the people who run your backups to make sure your data is safe, the people who bring you the network, the people who monitor it for security — and yes, the person who cleans the virus off your computer and replaces your monitor.
