Just wondering: Are you using NetworkManager?
When I installed Fedora 9, and was trying to resolve a problems with
various daemons that needed a working network, I played around with ifup
and ifdown, and noticed that they weren't working properly. A taken
down network was otherwise seen as still up, but not actually working.
And trying to bring a network back up again was hit and miss, it worked,
it didn't work, the network status was correct and incorrect.
[tim at localhost ~]$ uname -r
Don't send private replies to my address, the mailbox is ignored. I
read messages from the public lists.
