Hello everyone,

I have some problems in the use of nanolog.

I use l2_switch to be my target and use python code to start my mininet.
I want to see the message in ipc, so I use

~/bmv2/tools$ ./nanomsg_client.py --socket
There is not any message.

But the
~/bmv2/targets/l2_switch/learn_client$ sudo ./learn_client
It still can receive message from bmv2-0-notifications.ipc
I received 2 samples
Calling callback function
CB with 2 samples
ingress port is 1
ingress port is 2

I can't figure out what happened.

Thank you.

Best regards,
