Hello, in the following topology: n1----n2----n3----n4 where agents p1,p3,p4(of type "agent_p" derived from Agent) are respectively attached to nodes n1,n3,n4. my questions are: Q1: how to send packets from p1 to p4 without using "connect"? Q2:I want to let p3 read (or receive) packet sent to p4, how to do that? regards Ghassan
