[ns] broadcast works! but can't trace when SENDING!

[kenneth at daimi]

Ok, this one is new.

Finally I got broadcast to work thanks to Jeff Boleng posting:
http://mailman.isi.edu/pipermail/ns-users/2000-June/009635.html

So I can know send and receive packets using broadcast.
The problem is that I CAN'T see the packets send by the agent (AGT) in the trace file.
What I can see is the packets send and received by the MAC, and only see the packets received by the AGT. I repeat, I can't see the packets send by AGT.

As a said I made the necesary changes proposed by Jeff Boleng.

Somebody have the solution to my problem?

Regards, Kenneth

THIS IS THE C++ CODE THAT SEND THE PACKET.

      Packet* pkt = allocpkt(); 
      hdr_cmn* cmnhdr = hdr_cmn::access(pkt);
      hdr_ip* iphdr = hdr_ip::access(pkt);
      hdr_ping* hdr = hdr_ping::access(pkt);
      iphdr->daddr() = IP_BROADCAST;
      iphdr->dport() = 5555;
      iphdr->ttl() = 1;
      hdr->ret = 0;
      hdr->send_time = Scheduler::instance().clock();
      Scheduler::instance().schedule(ll, pkt, 0.0);

THIS IS THE TCL CODE
