Description Bastien Nocera 2007-04-04 13:06:56 EDT

eth0 is an e100 card

Despite having no wired cable plugged into my machine, NetworkManager still
tried to get an IP address on the wired network.

$ sudo ethtool eth0

Same here with the Fedora 7 test 4 KDE Live CD and ethtool correctly reporting 
no link detected because the cable is unplugged on purpose.


In /var/log/messages I have:

... NetworkManager: <info> Deactivating device eth0.
... NetworkManager: <info> Will activate wired connection 'eth0' because it 
now has a link.

but it doesn't.

looks like dup of #230256
Comment 3 Bastien Nocera 2007-05-21 17:58:09 EDT
A dupe indeed.
