Thanks for help.
but the problem persist
I have one client with every node but with
$ns set-address 26 5
I have a message telling that i exceed the port field
I had change that to
$ns set-address 20 11
with that i succed to have 700 nodes but with 1000 nodes i have a
segmantation fault
I don't understand the reason
Can someone help me
