[Bug 702802] Re: event "net-device-up" is triggered too early

[Stéphane Graber]

Current ifupdown does wait for DAD to complete so chances are that this
specific issue has now been resolved for IPv6 at least.

Also note that the event is called net-device-up, not net-device-
connected. All the event means is that the interface has been brought up
and the configuration has been applied. It doesn't do any connectivity
check with the outside world nor should it.

There is another ifupdown bug report covering suggestions on how to
address this bug #848823.


I'm going to close this bug as fix released for the DAD case, for the NFS case, this is a duplicate of 848823 (even though this bug technically came first, the latter has more information).

Title:
  event "net-device-up" is triggered too early

Status in “ifupdown” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: ifupdown

  Hello,

  on booting, the event "net-device-up" is triggered too early. The
  event is "sent" to other jobs immediately after the ifup command has
  been executed, but neither ifup nor the calling script /etc/network
  /if-up.d/upstart perform a test if the network connection is really
  working. The result of this behaviour is that a job needing network
  functionality, e.g. mounting NFS filesystems, is possibly started
  before other network machines are reachable and makes the computer
  hang. This happens when the network interface needs some time to
  negotiate the ethernet parameters with the network switch.

  Regards
    Christoph
