I am newbie to scripting. I have debian squeeze installed on my box. I have BIRD daemon to route traffic of particular IP. We add IP to bird-route.conf automatically from ruby script if traffic spikes up to specific range. I would like to know the possible ways to send notification of added IP to remove from bird-route.conf after certain period, for example say If script adds the IP in bird-route.conf file at 12.00AM so notification script should notify me after 48 hours to remove it. How can I achieve this ? shell, perl or ruby any of the scripting would work. Any help would be appreciated.
