[ns] Source & Destination ip is the same!

[Canhui Ou <canhuiou@yahoo.com>]

Hi,

I noticed that source ip address and destination ip
address in a packet are the same. If you add the
following c code to 'recv' in ping.cc and recompile
it, you can see the situation.

    {
        // Please include arpa/inet.h
	char pBuf[129];
	in_addr srcAddr, dstAddr;
	srcAddr.s_addr = hdrip->src_.addr_;
	dstAddr.s_addr = hdrip->dst_.addr_;
	sprintf(pBuf, "puts \"Source ip addr: %s \
Destination ip Addr: %s\n\"",
		inet_ntoa(srcAddr),
		inet_ntoa(dstAddr));
         // You can use tcl.eval(pBuf)
         printf(pBuf);
    }
I also found that the member variables, here_ & dst_,
of class Agent have the same ip address, namely
here_.addr and dst_.addr are the same.

Is this my mistake or NS's bug? Any suggestions and
comments are welcome.
