Tyson was taught to perfection how to work your way inside against somebody with a long jab, as he was very short.

Can anybody here give advise on what techniques to practice to learn getting in on the inside of somebody who is a lot taller than you , so you can actually fight up close.

I find because i am short, its very hard for me sometimes to get on the inside, and its really really frustrating.

Could you not try to bob n weave your way inside? Have you not already asked your trainer for advice?
