Accessing the network

Hello all :wink:

since last update, it seems that something is trying to SYNC with on TCP port 49152.
here is what netstat is showing me :
> $ netstat -tpn

Proto Recv-Q Send-Q Adresse locale Adresse distante Etat PID/Program name
tcp 0 1 SYN_SENT -

As you may have notice with netstat, my network is, so NOWHERE I’ve setup something to…

Please trust me on word : I don’t use any strange/customize addon or something.
As OSMC is installed on RPi2 I use few addon ; the only installed addon is Youtube.

Any idea how to identify what is trying to contact that unkown machine?

PS : (before someone ask : NO I don’t have new router/WIFI or network device that is trying to do something)

Maybe providing a debug enable complete log could help to go to the bottom of this issue
Alternatively record the request with tcpdump
