If you want a position for sysadmin in the Microsoft world, you're going to have to spend a few thousand getting certifications. You'll need those whether you have a degree or not.
If you're going for a position with Linux or Unix, check out a local LUG (Linux Users Group) for some great resources and job leads.
Don't stop there though. ... You never know when opportunities pop up and where, so keep your eyes open.
This is close, I think, if you want to work for a bigger shop.
As above posters have said, the HR Nazis read the spec and it says "degree in cs or related dis" and the door stays shut unless you know someone.
Get yourself enrolled in a college and go after that degree. You owe it to your future to expand your horizons.
But small and medium biz need help, and in this economy if they can get somebody junior to help BigBuxBob, there's a good chance you can get in the door, study your ass off - learn about EVERYTHING: mail, databases, LDAP, Active Directory, Web Application Servers, IIS & Apache, Linux, Unix, Windoz. Expect to take your lumps and pay your dues. Be ready when Bob has a vacation coming to fill his shoes!
A few tips:
- NETWORK - join users groups and meet people.
- Volunteer to help Non Profits with IT Stuff - heck, even helping cable a network is a good thing for your resume.
- Learn everything about networking and IP.
- Consume slashdot, sourceforge, and support sites.
- Keep a paper brain or a huge doc file that contains urls and commands you have used.
- Have a thumb-drive with a toolkit you can use to fix probs on unix, linux, windows. There are plenty out there - find and compile them for your self.
- Publish - have a blog people can find (which means having useful content, not just drivel).
- Never, ever, be without a current resume ready to email or hand out with 30 minutes notice!
Within a year or so, something will pop.
One final thought: Ask colleagues with degrees what their degree is in. Then ask if they are working in the field of their major. Approx 2/3 in tech will say no. Ask the rest how many hours (not credit hours - actual hours of class and study only) in their four years were in their Major. The answer is probably fewer than 1000. First two years and much of last two years is to make a well-rounded student who can (should be able to) read and write. The extremely competent may have LOTS more hours or be extremely bright, but the average joe... um, maybe not.
Do NOT be impressed by MS degrees from University of Boom Chalawalla or East Cha-ching. I've worked with a lot of guys with MS who can't write a script, couldn't troubleshoot a sick Apache.
Be confident. You will make it.
