How to test cat5/cat6 cable runs, using software-only, or simple tools? [closed]

Are there any utilities or simple tools or techniques to easily test a CAT5 cable, to see how well was it installed?

Cat5 is often installed by amateurs, but has been installed and "working" for years. Proper cable testers and certifiers like a Fluke or LanTech often cost over USD$1000 and people who have them are few.

Aren't there some sort of special network cards, or USB cat5-testing devices, one can plug into a computer and test the cat5 with software? Perhaps an Intel utility for their cards?

Buy a Fluke cable tester, they're what everyone else uses.

If you are going to continually test cables afterwards buy a fluke you won't be disappointed. If this is a one time only call around locally to companies and IT shops see what they would charge you to come out and test your runs. You could also do some searches on Google to rent a fluke cable tester. I found a few companies that do it.
