and another Ubuntu upgrade oddity!

Following on from this collection, I've just noticed this

$ iwlist eth1 scanning
eth1 No scan results
$ ifconfig eth1
eth1 Link encap:Ethernet HWaddr 00:1a:73:28:ec:d6
inet addr:192.168.1.9 Bcast:192.168.1.255 Mask:255.255.255.0

so I'm connected wirelessly through eth1 (I am honestly!) but it can't see any wireless access points. Pardon!?
PS - all explained now - you need sudo iwlist eth1 scanning
they've tightened up permissions on scanning for wireless connections. Not too surprising when you think about it.
