[srslte-users] Listening to M1U interface

[Borja Iñesta Hernández]

Hi,

Is there any way to receive the packets sent to m1u interface between  
mbms gateway and enb? I want to receive the packets that are being  
sent from the mbms gateway to the enbs and write them into a pcap  
file, to inspect them later using Wireshark.

I tried using socat with this command:

socat - UDP4-RECV:2153,bind=0.0.0.0,ip-add-membership=239.255.0.1:<local_if>

But keeps saying that this port is already in use. I have tried with  
multiple ports and starts listening but nothing is received. I used  
2153 because is the one used by the enb to stablish the connection  
with the mbms gateway in m1u.

Also I used 0.0.0.0 address as in the enb code and my local_if is enp3s0.

Thanks, Borja.
