Bug Description
I routinely sit on our work guest network which has a 1 hour DHCP lease time.
What I'm noticing is that every hour skype and pidgin are reporting "buddy offline,.....,buddy online". What appears to be happening is the NetworkManager is (successfully) renewing the lease - but appears to trigger whatever APIs it normally triggers when network changes occur. In other words, renewing a DHCP lease seems to be treated the same as resetting a network interface
I don't know if this is a bug or is expected behaviour, but from a user perspective I do not understand why successfully checking if the IP address you have is still valid should trigger anything: nothing has changed, so why "tell" other applications that something has? To put it another way, if I set a static IP, I bet these applications would no longer think network changes are occurring, so why can't the same thing happen with successful DHCP renewals
Thanks for listening
Jason
