Triaged/Medium; assigned to myself to look into whether the carrier
detection code does the right thing (which should be to try to re-
establish connections, a *maybe* try connections that were previously
failed).

Title:
NetworkManager does not re-enable connection which was disabled
because DHCP timed out
Status in “network-manager” package in Ubuntu:
Triaged
Bug description:
Binary package hint: network-manager
As requested by Mathieu Trudel in bug #274593, I'm opening a new bug.
If the DHCP server in the network goes down for some reason,
NetworkManager marks the connection invalid once DHCP request times
out:
Nov 8 10:59:19 lempo NetworkManager[975]: <warn> (eth0): DHCPv4 request
timed out.
Nov 8 10:59:19 lempo NetworkManager[975]: <info> (eth0): canceled DHCP
transaction, DHCP client pid 6586
Nov 8 10:59:19 lempo NetworkManager[975]: <info> Activation (eth0) Stage 4
of 5 (IP4 Configure Timeout) scheduled...
Nov 8 10:59:19 lempo NetworkManager[975]: <info> Activation (eth0) Stage 4
of 5 (IP4 Configure Timeout) started...
Nov 8 10:59:19 lempo NetworkManager[975]: <info> Activation (eth0) Stage 5
of 5 (IP Configure Commit) scheduled...
Nov 8 10:59:19 lempo NetworkManager[975]: <info> Activation (eth0) Stage 4
of 5 (IP4 Configure Timeout) complete.
Nov 8 10:59:19 lempo NetworkManager[975]: <info> Activation (eth0) Stage 5
of 5 (IP Configure Commit) started...
Nov 8 10:59:19 lempo NetworkManager[975]: <info> Activation (eth0) Stage 5
of 5 (IP Configure Commit) failed (no IP configuration found)
Nov 8 10:59:19 lempo NetworkManager[975]: <info> (eth0): device state
change: 7 -> 9 (reason 5)
Nov 8 10:59:19 lempo NetworkManager[975]: <info> Marking connection 'Auto
eth0' invalid.
Nov 8 10:59:19 lempo NetworkManager[975]: <warn> Activation (eth0) failed.
Nov 8 10:59:19 lempo NetworkManager[975]: <info> Activation (eth0) Stage 5
of 5 (IP Configure Commit) complete.
Nov 8 10:59:19 lempo NetworkManager[975]: <info> (eth0): device state
change: 9 -> 3 (reason 0)
Nov 8 10:59:19 lempo NetworkManager[975]: <info> (eth0): deactivating device
(reason: 0).
If I now unplug and replug the network cable (a common fix for network
problems), NetworkManager does not try to get a new IP address via
DHCP:
Nov 8 11:02:05 lempo NetworkManager[975]: <info> (eth0): carrier now OFF
(device state 3)
Nov 8 11:02:05 lempo NetworkManager[975]: <info> (eth0): device state
change: 3 -> 2 (reason 40)
Nov 8 11:02:05 lempo NetworkManager[975]: <info> (eth0): deactivating device
(reason: 40).
Nov 8 11:02:07 lempo NetworkManager[975]: <info> (eth0): carrier now ON
(device state 2)
Nov 8 11:02:07 lempo NetworkManager[975]: <info> (eth0): device state
change: 2 -> 3 (reason 40)
Rather, I must log on to my computer, click on the nm-applet and select Auto
eth0. This is highly inconvenient if I'm out of office and would like to do
something remotely. Otherwise I could just ask my colleague to replug the cable.
