How to debug nm-dispatcher not calling 01ifupdown

Asked by alainpannetier

Dear all,

I've got two Ubuntu laptops (both 10.10) both v 0.8.1.

"NetworkManager (version 0.8.1) is starting..."

One is a new Maverick install and the other has been upgraded many times since 9.04.

On the latter, setting up a custom script hook in adding 'touch /a.txt' at the top of /etc/NetworkManager/dispatcher.d/01ifupdown worked instantaneously. When the Wifi switch is pressed or the Applet disconnect option is selected, the a.txt file shows up under /

However, on the older laptop, I can't get nm-dispatcher to get called, or at least to execute its hooks. The same test yields nothing.

I've tried to run

NetworkManager --no-daemon -log-level=DEBUG

But there is no mention of nm-dispatcher in the output.

How can I

   1. Have a look at the source (I looked into the git repo but could not find where the source for the dispatcher lives).
   2. Find why the nm-dispatcher never gets called.

You might want to try start NetworkManager the following way:

sudo /usr/sbin/NetworkManager --no-daemon --log-level=DEBUG --log-domain=CORE

However, to figure out why the dispatcher doesn't run hooks on your system, make sure any file in /etc/NetworkManager/dispatcher.d/ is set as executable (permissions rwxrwxr-x or something similar), and that there is nothing at the beginning of a script to stop it from executing in certain specific conditions.

Can you help with this problem?
