I want to execute a script when network (any interface) goes up and when goes down (with parameters).
I've found easy to trigger first part with
start on (net-device-up IFACE!=lo)
but didn't manage to found an easy way to trigger either net-device-down, net-device-remove(d) , deconfiguring-networking
my job loks like this:
##################################################################
description "network test"
start on (net-device-up IFACE!=lo)
# stop on ((net-device-down IFACE!=lo) or deconfiguring-networking)
stop on net-device-removed IFACE!=lo
pre-start exec /opt/test.sh start "$UPSTART_JOB - EVENT: $UPSTART_EVENTS"
post-stop exec /opt/test.sh stop "$UPSTART_JOB - EVENT: $UPSTART_STOP_EVENTS"
##################################################################
to test it I just go to nm-applet and deactivate one interface.
I've finally managed to make it work creating a simple script in '/etc/network/if-post-down.d' to force emmiting the signal. something like this:
########################################
#!/bin/sh
[ "$IFACE" != "lo" ] || exit 0
initctl emit -n net-device-removed IFACE=$IFACE
########################################
I'm not sure if this is expecte behaviour, if this is a feature request or if it's a real bug, but for company pourposes I really need to emit a signal when any interface (not lo) goes down.
please, ask for further info |

EDITED: I can see here
https://lists.ubuntu.com/archives/upstart-devel/2011-January/001379.html
that '/etc/network/if-down.d/upstart' should emit net-device-down but in my case that's not true. so maybe the bug should be:
event not emited by '/etc/network/if-down.d/upstart' |
