We made actions plugin for OLSR for this purpose:
For example, we run it like this:
PlParam "trigger" "0.0.0.0>/etc/actions.d/olsr_gateway_action"
PlParam "trigger" "10.254.0.1>/etc/actions.d/olsr_dns_action"
PlParam "trigger" "10.254.0.2>/etc/actions.d/olsr_dns_action"
So if route to default gateway or dns server is made or it drops shell
script is called. We use this to get node into "isolation" mode where
we display special splash page for all request going outside of the
mesh telling the user that there is currently no connection and we are
sorry, but that he/she can help by making a node. It is much better
than that request just timeout.
