dear all,

I hold my hand up there was an entry in "hosts" GUI of ipfire PC about 
the old domain/ipaddress of windows PC but I swear I cleared out ipfire 
/etc/hosts so I dunno where that came from.

I think it might be something to do with arp cache on all the PCs  going
"I know about that"
Still no funny entries in nmap results now except windows PC doesn't 
show up at all but guess that is windows firewalling.

regards the CCTV camera is another thing. It's there but is not 
streaming on the ethernet, just the WIFI and appears to connect to cloud 
servers ( I'll leave that for another day ). my suspicion is that the 
Chinese are selling these off cheap to have a peek at European domestic 
habits.
