hardware i have:

cheap internet Router and 24 ports Hub
CABLE 1000' CAT5E Without the end
CRIMPER
50 RJ45 Head

Goal:

to make 20 of 25' long cables

---------------------------------
i clip the head to the cable

problems:
1. How to test the RJ45 cable without the network cable tester?
(to make sure all the heads are correctly clipped)

2. How to check the cable's signal good or not?
(transfer speed good or bad )

if i have to buy a network cable tester, do you have any recommandation?
(please! no fluke recommandation sample reason cost too much money)

also any network monitoring software recommand?

thank you

I'll defer the S/W piece to someone else.

As far as checking your connection...What I used to do in the field (in a pinch) is once you have crimped the headshell inspect the bottom of it (the side with the clip) and make sure you can see the copper teeth on all the pins poking thru the wires. Sometimes if you don't crimp hard enough they wont sink all the way through and possibly not make an adequate connection.

Once that is complete...plug it in. You won't get a link light on your DTE/DCE if the cable isn't built properly.

Now like I said, someone will most certainly recommend a piece of software to monitor your bits across the link for errors. but if you are connecting say router to router you can just check the physical interface attributes on both ends while spooling up some test traffic on the interfaces.

oh yea...Don't forget to use the proper wiring standard when building your cable... You can just Google it. Here is an example of T-568A & B

There are cheap cable testers to be bought fgor under 30 US Dollars. They are simply two small boxes with lights on them. You plug one box on either end of your cable, then turn the "Master" box on. The readings will tell you wether you have a straight through, crossover, or rollover cable. Simple as that.

yup, those are good for testing continuity. They are great when you first start learning to build cables however, once you start building a bunch you find yourself not using it.

If you plan to use them for 100/1000 you need something that is going to test for quality.
