In my case, having a root account on a few public-facing web servers translated to "Linux sysadmin, 3y experience", helping out a classmate with his freelancing project "C++ and Qt framework, 1y experience", e.t.c.
Second, if you want to continue in your studies, you should be able to get a paid internship in some local corporation. It is then easier to transition to full employment with one leg in the door already. That is how I got to company I work for now :)
Or you might go even further into academia, i.e. if you enjoyed writing your thesis, your advisor might help you with a teaching-assistant job, or a faculty sysadmin job and some universities even have their own developer departments (mine had one developing their university information system). Or maybe even a research fellowship.
And last, ask your classmates.
Some of them might be freelancing, and you might be able to get client/work from them (i.e. a friend of mine had a a mobile-app shop, and once he needed to finish one more app in the pipeline he had people for, and thats how I paid for half of my wedding :-)
Some of them might already be working, and if they remember you as a guy they would like to work with, you might be able to get a round or two of interviews head-start :-)
Ok, I think I might start with my friends/classmates first :-) That is how I got to the "Linux sysadmin, 3y experience" anyway :)
Good luck!
