I am running Linux on my PC. Recently I have been getting loads of messages in the sys.log of the form

192.168.1.121 is a Sony android television on my network

As I understand it 224.0.0.251 is related to DNS
192.168.1.51 is my PC

Is my television trying to hack into my computer?

Thanks for any advice.

Tcpdump the packets then check them out in Wireshark. It is some kind of multi cast packet.
 
5353 on multicast is mdns. nothing is hacking anything. :rolleyes:
 
I appreciate that the first line is multicast. The second line appears much more often in the log and appears to be directed at my PC. Does this mean the TV sees my PC on the network and directs a multicast to it?
