How to get self Interface address in receive packet method from socket?

[Hassam Mughal]

Greetings everyone!

I am trying to print the IPv4 Interface address of the interface that receives the packet. However, there is no method in the socket. My Code snippet is following;

static inline std::string
PrintReceivedPacket (Ptr<Socket> socket, Ptr<Packet> packet, Address senderAddress)
{
  std::ostringstream oss;


  oss << Simulator::Now ().GetSeconds () << " " << socket->GetNode ()->GetId ();
 
  if (InetSocketAddress::IsMatchingType (senderAddress))
    {
      InetSocketAddress addr = InetSocketAddress::ConvertFrom (senderAddress);
      oss << socket-> GetNode()->GetDevice(socket->GetNode ()->GetId ()) << " received one packet from " << addr.GetIpv4 ();
    }
  else
    {
      oss << " received one packet!";
    }
  return oss.str ();
}

Any guidance or help in this regard will be highly appreciated.

Thanks

Hi,

Maybe you can try something like this:

Ptr<Node> node = socket->GetNode ();
Ptr<Ipv4> ipv4_ptr = node->GetObject<Ipv4> (); // Get Ipv4 instance of the node
Ipv4Address addr = ipv4_ptr->GetAddress (1, 0).GetLocal (); // Get Ipv4InterfaceAddress of 1st interface.
std::cout << "Node: " << node->GetId() << " Address: " << addr<<std::endl;

Best regards,

George

Dear George,

Thanks for this solution. Let me try it and get back to you.

I am encountering an issue, which is that as I have 3 interfaces, so I don't know on which Interface I have received this packet on, and If I do this for every interface, it will give me the result as follows:

So, what should be my strategy in such situation?

Kindly find my code attached hereby. I have tried to have three interfaces with different port numbers for each interface.

Well, my first instinct is to say that the interface that receives the packet is that on the same subnet, in that case 10.1.3.1.

Have you tried checking on your trace file to see the traffic? You could try and run: tcpdump -nn -tt -r <your-trace>.pcap

The traffic for the Dsdv_Manet_2Nodes_10SimTime-0-1.pcap is as follows: Which shows that the packets are received at their respective interfaces such that for 10.1.1.2 --> 10.1.1.1 and 10.1.2.2 -->> 10.1.2.1

That was the desired outcome, right?

Yah. Thanks, So it is working fine. But when I install a routing protocol on it, it doesn't print routing table accordingly. And the table looks like this

I don't have any relevant experience with the routing protocol, so I can't be of help on that, sorry.

Best regards,

George

Ahan, it's alright. Thanks a ton. Do you have any experience with DCE ?
