No Way Know How

I just upgraded my raspberry pi media centre to raspi 3 running kodi on osmc. all is well apart from being unable to ping or ssh into my new pi on static IP 192.168.1.239. pinging gives me host unreachable. ssh gives me no route to host on port 22. tried adding -v to ping command on the suggestion of a forum troubleshooting post [mitch@latitude ~]$ ping -v 192.168.1.239 ping: socket: Permission denied, attempting raw socket... ping: socket: Permission denied, attempting raw socket...
