I followed SFC 101 and in the last section which is "send packet" I get this error:

ERROR:__main__:No response from

and from start_agent.sh file I get this error:

struct.error: unpack requires a bytes object of length 20

I run their command which is:

sudo python3.4 sff_client.py --remote-sff-ip --remote-sff-port 4790 --sfp-id 1 --sfp-index 255

Any idea what I should do?
