Hmm.... Getting closer!

I have a MacBook Pro, when my son turned it on and started watching YouTube, the problem appeared!

The MBP uses Wireless DHCP to obtain it's IP address from the FritzBox 7390 running the latest series 5 firmware (not series 6 as they dropped SMB sharing of USB attached Hard drives for useless features like household control, which I don't use)

I asked him to turn the MBP off and the problem went away.

Back on and to login, the problem returned.

I asked him to close all the running apps but leave the MBP logged in.

The problem persisted.

I asked him to logout of the MBP but leave it turned on.

The problem went away.

I asked him to login but not start any apps, or, if any apps do start, to stop them.

The problem returned.

I login to my account on the MBP

The problem returned.

My account only has Messages, Safari and Finder running.
Using the activity monitor, the only processes that have made any use of the network was SystemUIServer.
Other processes started using the network after I made the above observation, including OwnCloud, Safari and Safari Networking (after I verified the MBP could access my domains), plus others.

Oh, and by the way, the MBP can access my domains! It's only my Gentoo Linux System that can't.

So, what I am really interested in, is that the MBP is affecting my Gentoo Linux in some way. How?

I begin to be suspicious of the routing in the FritzBox...


sigh...

lyallp,

IP address collisions?

Does the Macbook have the same IP address as something else on your LAN, or maybe the Gentoo box?
Horrible things happen to networking if you get the same IP address allocated to two or more devices.

If IP address collisions was the problem, then the situation when the MBP is turned on but not logged in would have the problem persisting, whereas, the problem goes away.

Nice thought, I have installed arp-scan to test it, regardless. :)
