The echo-server should work just fine even if the multicast context cannot be get. By default there are only two contexts so the multicast would fail always anyway and the program would not run properly.

Description of various IP stack test applications ================================================= echo_server ----------- The echo server test implements a network server that listens UDP sockets. If that socket receives data, the server reverses the data and sends it back. The echo client can be running in the host system in which case you need to use SLIP to connect to qemu. This usage scenario is described in net/ip/tools/README file. This is the default if you type "make qemu" in echo_server test application directory. The network IP stack hooks right under IP stack (network level) and sends the IP packet to host using SLIP. The layer 2 is the SLIP layer in this case, no radio layer is simulated or used. The echo server qemu instance can also be running against echo client that is running in another qemu. For this you need two terminal windows. In terminal 1 go to echo_server directory and type "make server". This will start the echo server and setup qemu pipes in suitable way and it will also start monitor application that will store the transferred network traffic into pcap file for later analysis. Then in terminal 2 go to echo_client directory and type "make client". This will start the echo client that will start to send data to the server and verify that it has received the data back correctly. In the two qemu case we are simulating the whole radio network meaning that the saved pcap file will contain 802.15.4 network packets. echo_client ----------- The echo client test implements a network client that will send UDP data to the echo server. The client verifies that it has received data to the sent message and that the data is correct. The echo server can be running in the host system in which case you need to use SLIP to connect to qemu. This usage scenario is described in net/ip/tools/README file. This is the default if you type "make qemu" in echo_client test application directory. The network IP stack hooks right under IP stack (network level) and sends the IP packet to host using SLIP. The layer 2 is the SLIP layer in this case, no radio layer is simulated or used. The echo client qemu instance can also be running against echo server that is running in another qemu. This test scenario is described in echo_server chapter above.
