How to disable ASLR for FreeBSD?

Question

I am currently taking a computer security class and want to try porting some of the class exploits to my FreeBSD machine. For linux, I managed to disable ASLR using

 "echo 0 > /proc/sys/kernel/randomize_va_space". Compiling with "-fno-stack-protector -z execstack" 

Flags

on gcc NX and canaries , and I assume this will be the same for FreeBSD. Does FreeBSD have similar features to disable ASLR? Thank you for your time.
