my old father is using ubuntu-gnome. He has no static ip address. In order to perform remote administration, I need to know his ip. I was using dyndns free account (configuration in the adsl modem), but this will stop working in a couple of days.
I would like to run a script each time he logs in to publish his ip on my website. I have tried to put a script on the boot, but the network is not available. It seems that it is gnome 3 that starts the network, but I do not know much about gnome 3.
How should I do to have my script run automatically as soon as the network is available ?
One possible non-elegant solution for this is to put your script in his cron to run every X minutes :)
Looking to mine /etc/NetworkManager/ looks like there is a folder dispatcher.d that I think it'll do what you want. Just experiment with a bash/perl/python w/e script in there set the permission appropriately. You can find the UUID in the system-connections/ folder. More information is available in man networkmanager.
EDIT: Look what I found: https://askubuntu.com/questions/13963/call-script-after-connecting-to-a-wireless-network. Seems like this is exactly what you want.
