[Mukanyiligira Didacienne]

Hello,
I am sending a multicast datagram using the
Example: Sending multicast datagramand
Example: Receiving multicast datagram

The sender is a linux container and receiver is a node in ns3 simulation.

and the following are error I am getting while I run those examples.

Could any one tell me how to solve such kind of problems.


This is the message I am getting while I run the code on sender side.

sudo: unable to resolve host left
Opening the datagram socket...OK.
Setting the local interface...OK
Sending datagram message...OK

and this this the message I getting while I run the code on the receiver
side.
