I am getting a security alert...can anyone help ?

My security prog pops-up every half hour and tells me there are two unknown devices on my network.

It gives an IP and a MAC address for each one.
The IPs are: 192.168.93.254 and 192.168.72.254
The macs are: 00:50:56:f8:c0;93 and 00:50:56:fd:19:8d

Any clue as to what these might be ?

I have a D-link router (supposedly secured) with wireless disabled.

You have a router, is there anything besides your computer connected? VOIP gizmo? Squeezebox? Anything?

That's a VMware mac address, so either you have VMware loaded and are emulating some other OS, or someone else on the network is.

solved - this could happen to you......

Earlier today, I downloaded the free VMWARE player and was having fun running Ubuntu Linux as a virtual machine.

When I exited, two VMWARE virtual networks were left behind and it was those networks that were showing unknown devices.
This is apparently how Linux connects with the internet in a virtual environment.

In any case, I disabled those networks and the alert went away.

Interesting. Where do you look up MACs like that?

The worst part is I have a couple hundred OUI's memorized at this point. I had to look up the VMWare mac, but often... I just know what brand it is.

Hmmmm....Usually geeks don't have such nice cars.

Seriously though, that would worry me. Maybe you just need to drink more.
