hello everybody

it is my first using of contiki i dont know anything about it, but i
started to learn it, so i started by two examples of rpl-border-router,
the first is to use rpl with udp and the second use rpl and websense to
add other mote, in the second i can't connect the node and when i use :

user [ at ] instant-contiki:~/contiki$ make connect-router-cooja TARGET=sky

i found

make: *** No rule to make target `connect-router-cooja'. Stop.

or

user [ at ] instant-contiki:~/contiki$ make TARGET=sky

i found

make: *** No targets specified and no makefile found. Stop.

so how can i resolve this problem

and how is the difference between this two examples?
