script to run after hotspot authentication?

[Paul Wouters]

Hi,

Is there a way to run a custom command after hotspot authentication?

Fedora has/had some ways of detecting portals. dnssec-trigger,
NetworkManager and Gnome3. I think the current method is supposed
to be based on the latter. So I guess the problem that is used is
/usr/libexec/gnome-shell-portal-helper

Does that signal anything back to NM? It seems the helper itself has
no "post" commands it can run.

Specifially, I'm trying to solve the problem of IPsec MOBIKE support.
When we receive a notification of the new IP address via netlink, the
network isn't working yet and our mobike address update request using
this new IP address dies in the portal filter. The user authenticats
and the captive portal disables the filter, but we no longer receive
any update about this event from netlink/kernel.

You might be able to hook into dhclient.

See /usr/share/doc/dhcp-client/README.dhclient.d

Writing "problem" instead of "program" seems quite appropriate, given
the quality of most software in the world.

That happens when you obtain an IP address. There is no notification
method that I know about that will signal me when the hotspot
authentication has happened. This could be seconds or minutes (minutes
is when I open my laptop without typing and grab my coffee at the coffee
shop :)

What about the NM hoooks[0]?  I've been playing with them recently and 
you get all sorts of events prior to actually gaining a lease.
